| #1257097 (Received by flhurricane at: 6:39 PM 13.Jan.2026) AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 529 PM CST Tue Jan 13 2026 ...New AVIATION... .KEY MESSAGES... Updated at 525 PM CST Tue Jan 13 2026 - After today, minimal rain chances until next week - Elevated fire weather conditions Wednesday afternoon behind cold front - Wind chill values in the 30s Thursday and Friday morning && .DISCUSSION... Issued at 1208 PM CST Tue Jan 13 2026 Light rain and virga earlier this morning over South Texas continues to linger in eastern areas early this afternoon. I do expect most if not all of this light rain to come to stop by late this afternoon, with mostly cloudy conditions and light offshore winds limiting highs in the mid 60s. Drier air and mostly clear skies tonight will allow for morning lows to drop into the low-mid 40s and highs to climb into the 70s Wednesday before our next cold front pushes through in the afternoon. Relative humidity values dropping to 20-30% with northerly wind gusts of 20-25 mph and above normal Energy Release Component (ERC) values Wednesday afternoon, will likely result in elevated fire weather conditions across the Brush Country and portions of the inland Coastal Plains. Onshore flow returns briefly Thursday night through Friday, before another cold front moves into South Texas Friday night into Saturday morning. Low confidence on the southern extent of the front, with both ECENS/GEFS showing the front stalling west to east across the CWA while the CMC has the front plow through. Temperatures and any rain chances will be heavily dependent on the location of the front, don`t expect great rain chances with PWAT values just near or slightly below normal. Models are in good agreement with onshore flow and southerly flow aloft returning early next week ahead of a front, bringing PWAT values to the 90-99th percentile and rain chances Monday into Tuesday. Model discrepancies become more apparent with this front and the mid-level low/trough developing off of northeast Canada. Highs into early next week will range from the 60s to 70s and lows in the 40s through the rest of this week, warming into the 50s early next week. && .AVIATION... (00Z TAFS) Issued at 525 PM CST Tue Jan 13 2026 VFR conditions through the TAF period even as a dry cold front moves through the region Wednesday afternoon. Winds overnight will be light and variable. Then as the front approaches then moves through the area, winds with a westerly component will shift from the north and gust up to around 20-25 knots tomorrow afternoon/evening. Rain chances are virtually zero with this frontal passage. && .MARINE... Issued at 1208 PM CST Tue Jan 13 2026 A gentle to moderate (BF 3-4) breeze will continue through Wednesday morning. Winds will increase to fresh to strong and shift northerly (BF 5-6) Wednesday afternoon through Thursday morning as another cold front moves across the waters, leading to Small Craft Advisory conditions. Winds will diminish to gentle to moderate (BF 3-4) Thursday afternoon into Thursday night. A gentle to moderate (BF 3-4) southerly breeze returns Friday before another cold front stalls across the area this upcoming weekend, shifting winds out of the northeast and occasionally fresh (BF-5). && .FIRE WEATHER... Issued at 1208 PM CST Tue Jan 13 2026 A cold front will usher in drier air (minimum relative humidity values less than 30%) Wednesday afternoon and continue each afternoon through the end of the week which, when combined with above normal ERC values, could lead to elevated fire weather conditions through the end of the work week. Elevated fire weather conditions are most likely Wednesday afternoon with northerly wind gusts of 20-25 mph. Following, light winds will limit our fire weather threat and keep us well below thresholds for critical fire weather concerns. && .PRELIMINARY POINT TEMPS/POPS...

| #1257096 (Received by flhurricane at: 6:33 PM 13.Jan.2026) AFDILM Area Forecast Discussion National Weather Service Wilmington NC 631 PM EST Tue Jan 13 2026 .WHAT HAS CHANGED... No significant changes to the forecast have been made. The main focus will be the arctic air moving in Thursday and beyond. && .KEY MESSAGES... 1) Rain Chances Return on Wednesday 2) A pair of strong arctic cold fronts moving through Thursday morning and again Saturday night will bring well below normal temperatures to the area. && .DISCUSSION... KEY MESSAGE 1... Rain Chances Return on Wednesday A lifting shortwave will move through the area on Wednesday in advance of a cold front on Thursday. Moisture above 700 mb is more than sufficient for precip, but dry air in the low levels will likely impact rain rates and QPF. Light rain will likely be focused along the coast where isentropic lift is maximized. Unlikely to see more than a few hundreths of rainfall through 12Z Thursday. Evaporative cooling should keep temperatures in the mid 50s. KEY MESSAGE 2... A pair of strong arctic cold fronts moving through Thursday morning and again Saturday night will bring well below normal temperatures to the area. No measurable precipitation is expected through the period. Cold arctic air will move in behind the first of basically two fronts Thursday and again this weekend. The coldest lows will occur Friday and again Sunday mornings when upper teens to lower 20s are expected. Apparent temperatures will be well into the teens. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... VFR tonight through midday Wednesday with increasing high clouds. An isolated shower is possible at midday through mid- afternoon at inland terminals and mid afternoon through evening for coastal terminals. Potential for brief MVFR if a shower moves over a location, best chances would be along the coast, but duration of any restirction will be brief. Extended Forecast...Restrictions possible before midnight Wednesday night, best chance along the coast. VFR returns Thursday. && .MARINE... Through Wednesday... Winds turn southwesterly this afternoon and this evening, increasing overnight. West to southwest winds on Wednesday will precede a shortwave moving northeastward through the afternoon. With clouds increasing late tonight and early Wednesday, precipitation over the nearshore waters could begin as early as mid morning. Wednesday Night through Sunday...Strong small craft advisory conditions are expected Thursday and again this weekend via strong cold air advection behind a couple of arctic cold fronts. With the offshore flow being primarily offshore significant seas will be somewhat limited considering the wind speeds...mainly 2-4 feet. Some isolated five footers are always fair game outer waters with the strongest of gusts. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...None. SC...None. MARINE...None. && $$ |
| #1257095 (Received by flhurricane at: 6:33 PM 13.Jan.2026) AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 519 PM CST Tue Jan 13 2026 ...New AVIATION... .KEY MESSAGES... - Negative tide levels are anticipated in the bays this week, most significant late Wednesday-Thursday. - Two dry cold fronts are forecast to push through the area: one on Wednesday and another Friday. - Brief warm up on Sunday before a third possible cold front Monday night/Tuesday morning. && .DISCUSSION... Issued at 1213 PM CST Tue Jan 13 2026 A weak upper level low over central Texas this afternoon will continue eastward tonight, merging with a broader trough digging across much of the Central/Eastern Conus. We`ve already seen widespread light showers across the region on radar, indicating that PWs of 0.75-1.00 inches have been sufficient with the amount of lift provided by the low. Shower coverage is expected to peak this afternoon (right around now) as we get the full forcing from the passing upper level low. Activity then tapers off from west to east into overnight into Wednesday as the low exists the area. Anticipate another cold evening with lows for Wednesday morning in the 40s/lower 50s. Wednesday kicks off with the aforementioned upper level low, now shortwave, east of the area, now embedded within the much stronger mid/upper trough spanning the Central/Eastern CONUS. This larger upper level feature is anticipated to push a weaker reinforcing front through SE Texas on Wednesday. Winds may briefly shift W/WSW early in the morning due to a prefrontal trough moving in from the north. The reinforcing front should lag behind it, entering the Brazos Valley during the late morning, then moving off the coast during the late afternoon. PWs will be fairly low, generally under 0.75", thus showers will be extremely sparse if any form to begin with. Breezy northerly winds and cooler temperatures should settle in behind the front. Daytime highs may top out in the 60s/lower 70s, but anticipate much cooler temps overnight with lows for Thursday morning in the 30s/40s. A light freeze could occur in many spots across the Piney Woods area near Crockett. Thursday won`t be a particularly active day as we find ourself post- cold front. Surface high pressure should pass over the region during the daytime with breezy northerly winds early in the day becoming light and variable, then later shifting southeasterly in the evening. Daytime highs will be fairly cool as onshore flow is (tentatively) set to occur after peak heating, with highs topping out in the 50s. After onshore flow is resumes, we`ll see moisture slowly return overnight, which should help limit the full extent of cooling overnight. Lows for Friday morning will should be slightly warmer, though still in the 30s/40s across much of the area with some lower 50s along the coast. Friday should see another mid/upper level trough dig through the Northern Mississippi River Valley/Great Lakes. This trough should send another cold front towards SE Texas, which should push into the Brazos Valley during the late afternoon and later off the coast some time around midnight. PWs by this point are forecasted to be around 0.5" or less. Rain chances will be very low with this frontal passage too, but there is still a chance that some light showers could develop along the coast as moisture pools. Highs during the daytime should top out in the 60s/lower 70s. Breezy and cooler air filters in overnight into the early morning hours with lows for Saturday morning ranging from the 30s/40s to possibly lower 50s at the coast. Could see lows touch the freezing mark across the northern edge of our CWA. Saturday on the whole should feature benign, post-frontal weather as high pressure fills in over the region, causing winds to relax and shift northeasterly. Highs should reach the 50s/60s during the daytime. Clear skies aloft from high pressure and with northerly flow still in place, we should see some of the coolest temperatures overnight into Sunday morning with lows in the 30s/lower 40s inland and mid/upper 40s along the coast. Sunday will see surface high pressure move off to the east into the Lower Mississippi River Valley, allowing onshore flow to return during the afternoon. This will usher in WAA and bring gradually warming temperatures and increasing moisture into next week. Highs for Sunday should reach the upper 50s/60s during the daytime. Overnight temperatures will be slightly warmer, but still cool with lowers for Monday morning anticipated to bottom out in the upper 30s/lower 50s. Forecast certainty decrease heading into next week, but signs suggest that we`ll see at least one more afternoon of warmer weather on Monday. Highs are anticipated to reach the the 60s/lower 70s during the daytime, with some isolated showers/storm chances possible during the daytime as PWs climb above 1.0 inch. Long range models suggest that another mid/upper level trough may dig across the Northern Plains/Great Lakes/Ohio Valley on Monday, sending another cold front into SE Texas. Timing is still up in the air, but anticipate the FROPA to occur some time Monday afternoon/evening or early Tuesday Morning. 03 && .AVIATION... (00Z TAF Issuance) Issued at 515 PM CST Tue Jan 13 2026 Widely scattered light shra will end this evening, yielding to a mostly cloudy VFR deck through the night. Couldn`t rule out localized MVFR cigs by morning. Skies are expected to clear tomorrow while winds increase from the north the wake of a cold front. North winds sustained to around 15 knots with gusts over 20 knots are expected by late morning and early afternoon. && .MARINE... Issued at 1213 PM CST Tue Jan 13 2026 Mariners should remain mindful of negative tide levels through the week, especially around low tide cycles in the central and northern half of the the bays. Another cold front will push off the coast Wednesday afternoon, prompting Small Craft Advisories across all bays and waters. Low Water Advisories may be needed overnight into Thursday morning as water levels approach -1.0ft MLLW. High pressure passes over the area Thursday, causing winds and seas to decrease and shift southeasterly. Another cold front is slated to push off the coast late Friday night/early Saturday morning, bringing moderate northeasterly winds in it`s wake. 03 && .PRELIMINARY POINT TEMPS/POPS...

| #1257094 (Received by flhurricane at: 6:33 PM 13.Jan.2026) AFDBRO Area Forecast Discussion National Weather Service Brownsville TX 530 PM CST Tue Jan 13 2026 ...New AVIATION... .KEY MESSAGES... Updated at 529 PM CST Tue Jan 13 2026 - There is a low (15-30%) chance of intermittent light rain or drizzle late this afternoon into the early nighttime hours tonight. - A cold front is expected to pass through the region Wednesday evening into Wednesday night. - A Small Craft Advisory is likely for the Lower Texas coastal waters Wednesday night into Thursday as strong northerly winds behind the front leads to adverse marine conditions. && .DISCUSSION... Issued at 1149 AM CST Tue Jan 13 2026 A mid-level trough moves eastward over central Texas today, passing north of our region, with slight upper level divergence and a weak jet aloft continuing into tonight, generating a low (15-30%) chance of rain from a line of isolated to scattered light showers or drizzle, moving east from the Northern Ranchlands and Mid/Upper RGV this afternoon and exiting the Lower RGV tonight. Ahead of the line, light northerly winds shift to southwesterly as the line exits, becoming light westerly by Wednesday morning and northerly by the evening hours, influenced by lower level winds shifting ahead of a ridge and cold front diving into the Southern Plains. The cold front passes through Deep South Texas and the Rio Grande Valley Wednesday evening into Wednesday night, leading to breezy conditions near and along the immediate Lower Texas Gulf coast, with northerly winds of around 20-25 mph and gusts up to 30 mph. Thursday into Friday, winds subside and become southerly by Friday as a surface high pressure shifts east from the Southern Plains to the northeastern Gulf. Another ridge flies southeastward over the Plains on Friday, sending another cold front, possibly late Friday night into Saturday, shifting winds out of the northeast through Saturday and gradually becoming southeasterly by Monday. As moisture rebuilds into the region next week, there could be an increase in PoPs to a low (15-30%) chance of rain along the coast Monday, expanding inland into Tuesday. Near to slightly below average temperatures today (highs in the 60s) and tonight (lows in the 40s/50s) become above average on Wednesday as skies begin to clear and downsloping westerly winds raise highs into mostly the 70s to near 80 F. Temperatures falling back to the 40s/50s overnight Wednesday as skies become mainly clear behind the front, allowing for efficient radiational cooling. Cold air advection via northerly to northeasterly winds cool temperatures back to the 60s on Thursday before 70s return on Friday with morning lows in the 40s/50s continuing into the weekend. A moderate risk of rip currents continues through Wednesday afternoon. && .AVIATION... (00Z TAFS) Issued at 529 PM CST Tue Jan 13 2026 Through 00z Thursday....VFR conditions are expected to prevail through the 00z TAF period. Through this evening/tonight, winds will be light and variable to calm if not out of the north with speeds up to 5 kts. During the day on Wednesday, winds will be out of the north with speeds between 5- 10 kts. && .MARINE... Issued at 1149 AM CST Tue Jan 13 2026 Gentle northerly winds become light westerly winds by Wednesday morning along with slight (1-2 feet) seas along with a low (15-20%) chance of patchy light rain or drizzle. Winds turn northwesterly, enhancing to moderate to fresh late Wednesday morning into the afternoon. A Small Craft Advisory is likely Wednesday night into Thursday as a cold front passes through the Lower Texas coastal waters, bringing strong northerly winds and moderate (6-8 feet) seas, followed by improving conditions Thursday afternoon into Thursday night. Winds become southerly along with slight (1-2 feet), possibly by Friday morning, with gentle to moderate southeasterly winds continuing through the weekend with a potential weak cold front Friday night or Saturday as well as building chances of rain next Monday. && .PRELIMINARY POINT TEMPS/POPS...

| #1257093 (Received by flhurricane at: 6:27 PM 13.Jan.2026) AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 623 PM EST Tue Jan 13 2026 ...New AVIATION... .KEY MESSAGES... Issued at 620 PM EST Tue Jan 13 2026 - Tonight, a couple degrees warmer with isolated to widely scattered showers developing, perhaps an isolated lightning storm south of Melbourne, as moisture increases. - Strong cold front arrives Wednesday night into Thursday morning, bringing a brief increase in rain chances. - Below normal temperatures Thursday onward; sub-freezing morning lows and frigid wind chills in the 20s to 30s, especially Friday morning and next Monday morning. && .DISCUSSION... Issued at 308 PM EST Tue Jan 13 2026 Rest of Today-Tonight...Florida remains under weak surface high pressure between a stationary front draped across the Florida Straits to our south and a deep low pressure system tracking across the eastern US to our north. Moisture in proximity of the stationary front extending into Central Florida and a weak surface trough lingering right along/off the Atlantic coast are producing lots of cloud cover, and even a few light sprinkles this afternoon. Through the rest of the evening and overnight, the trough and front are forecast to gradually consolidate into a weak surface low that will begin to lift north-northeastward, dragging higher moisture over the area. Very low (20% or less) rain chances this afternoon gradually increase northward, topping out at 20-30% inland late tonight/early Wednesday morning, before shifting offshore as drier air starts to get wrapped behind a developing weak cool front. Can`t rule out a lightning storm across the Treasure Coast counties and maybe southern Brevard. Afternoon highs up a bit but still in the U60s-M70s. Overnight lows up to he L50s-M60s. Wednesday-Thursday...The weak surface low will continue to lift northeastward, pulling the attendant NNE-SSW oriented cool front draped across the southeast Florida peninsula in the morning offshore by the afternoon. Cool air advection in westerly flow behind this boundary subtly brings temperatures down a bit across most of the area, with Wednesday afternoon highs in the M60-L70s for all but the Treasure Coast counties who remain in the M-U70s. The low early morning rain chances (20-30%) push offshore as the drier and cooler air filters in. There is a low (around 20%) chance for a lightning storm to develop over the Treasure Coast counties, and the nearby Atlantic waters. Some gusty conditions possible Wednesday afternoon with 10-15 mph winds. A slug of very chilly air by way of a pair of cold fronts then pushes into Florida, with the first front arriving Wednesday night, followed by the stronger reinforcing front arriving Thursday morning. Some moisture recovery is expected in proximity of the first front (PWATs down to below 1" in places Wednesday afternoon increasing to 1.25-1.35" overnight), which combined with ample forcing will support areawide 40-60% rain chances Wednesday evening into Thursday morning. However, instability for deep convection is virtually non-existent (MUCAPE only 200 J/kg at best across the southern counties), and as a result lightning storms aren`t expected. There is still some degree of uncertainty when and how much rain locations will receive. General CAMs consensus and HREF has rounds of showers pushing through between 7 PM Wednesday and 9 AM Thursday, but could see showers get started as early as 4 PM pretty much anywhere, and linger into the late morning across the southern counties. QPF also runs the gambit. HREF 24-hour max falls short of half an inch, which is inline with a very dry GFS at around 0.10" in the operational and 0.10-0.25" 90th percentile in the ensemble. The ECM is a little more optimistic at 0.20-0.40" in the operational and up to around 0.60" 90th percentile in a band across the northernmost counties in the ensemble. Overall the rainfall assessment looks to be most places will get 0.10" or less, while a few lucky spots receive up to around 0.50". Temperatures drop a bit Wednesday night, back down into the U40s-U50s, then plunge Thursday between the arrival of the second front and cloudy skies. Afternoon highs forecast to remain chilly in the U50s north of I-4, struggle to make it to the 60s along the corridor, and only reach the 60s to the south. Breezy northwesterly winds (approaching 15 mph with gusts up to 25 mph) will add some bite to the cool Thursday temperatures. Friday-Monday...Before stepping outside for work or school Friday morning, be sure to dress warmly! Forecast morning lows have not changed much from the previous cycle, maintaining the prospect of temperatures at or below freezing along and north of I-4, in addition to sub-freezing lows across interior ECFL as far south as Lake Okeechobee. Making it feel even colder will be a northwest breeze, sending wind chill values into the mid/upper 20s for a majority of the area. As a result, a Cold Weather Advisory will be needed for a large portion of ECFL Friday morning. Winds decrease through the day Friday into early Saturday as high pressure builds over the peninsula behind the fronts. Despite plenty of sun Friday afternoon, temperatures will really struggle to get out of the 50s from Osceola/northern Brevard and points north (low 60s south). Mostly clear conditions Friday night sets the stage for another cold night (30s-mid 40s). With lighter winds overnight, there is a possibility of frost developing Saturday morning over portions of the area. Daytime temperatures make a comeback, climbing into the 60s to low 70s. But then... Below normal temperatures look to be reinforced by another cold front Saturday night into Sunday. A lack of moisture along this front is keeping rain chances out of the forecast. Temperatures swing colder again Sunday into early next week, with lows in the 30s to mid 40s and highs only in the 50s and 60s. Sub-freezing temps are possible again, especially Monday morning. Behind the front, northwest winds will again add a wind chill factor with values falling into the mid 20s to low 30s Monday morning. && .MARINE... Issued at 308 PM EST Tue Jan 13 2026 Rest of Today-Wednesday...Generally favorable ableit a bit rainy boating conditions nearshore forecast through the day Wednesday. A weak low pressure system developing from a surface trough near the Atlantic coast and a stationary front draped over Florida Straits lifts into portions of the peninsula and local Atlantic waters tonight, then pushes well offshore by Wednesday evening. Winds will be shifty at 5-10 kts until the system departs, becoming westerly 10-15 kts nearshore and 15-20 kts (briefly over 20 kts in the afternoon) offshore Wednesday. Small craft should exercise caution offshore Wednesday. Rain chances 20% or less this afternoon gradually increase to 20-30% early Wednesday morning as higher moisture lifts into the area with this system, then decrease through the rest of the morning and afternoon as it departs. An isolated lightning storm mainly across the southern waters and coast can`t be ruled out. Seas 2-4 ft. Wednesday Night-Saturday...Boating conditions deteriorate Wednesday night and Thursday as a pair of strong cold fronts quickly push through Florida and the local Atlantic waters. Westerly winds 10-20 kts early Wednesday night shift northwesterly and increase to 15-25 kts by Thursday morning, then further increase to 20-30 kts Thursday evening, before settling down to 10-15 kts from the north by Friday morning. Seas build to 3-5 ft across the waters by Thursday morning, then jump to 7-10 ft offshore, possibly higher in the Gulf Stream Thursday night. Seas subdued closer to shore by the offshore wind component, but still building to 4-7 ft. Seas subside through Friday, settling to 2-5 ft Friday night. Boating conditions briefly more favorable Saturday before another cold front. Scattered to numerous showers and isolated lightning storms possible Wednesday evening through Thursday afternoon, then dry conditions. && .AVIATION... (00Z TAFs) Issued at 622 PM EST Tue Jan 13 2026 Continued VFR CIGs generally 045-060 AGL for much of the period with ocnl breaks. MVFR CIGs are forecast to develop MCO northward aft 08Z through 14Z-16Z then VFR conds return, again. Winds becoming light/variable this evening.

| #1257092 (Received by flhurricane at: 6:06 PM 13.Jan.2026) AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 551 PM EST Tue Jan 13 2026 .WHAT HAS CHANGED... The model trends continue to agree on a more progressive (faster) and drier solution for the late week system. No accumulation to trace amounts of winter precipitation is expected Thursday morning. && .KEY MESSAGES... 1) Remaining dry and mild through Wednesday with a light breeze. 2) Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thurs. Some light precipitation is possible late Wed, potentially ending as a brief period of non- accumulating to trace light snow Thurs morning. 3) Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. && .DISCUSSION... As of 300 PM EST Tuesday... KEY MESSAGE 1...Remaining dry and mild through Wednesday with a light breeze. Strong surface high pressure (~1028 mb) to the south and southwest dominates the local weather today with mostly sunny skies and temperatures generally in the mid 50s as of the time of writing. Temperatures have begun overachieving slightly as SSW winds allow a warmer airmass over the area. High temperatures will likely be a few degrees above current obs in the upper 50s to near 60F in the SE VA/NE NC. Despite remaining mostly clear tonight, temperatures will be more mild than last night with lows in the mid to upper 30s. Mid to high clouds will increase Wednesday ahead of the next cold front, but SSW flow will remain, keeping temperatures mild with highs in the mid to upper 50s (lower 50s for the Eastern Shore). KEY MESSAGE 2...Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thurs. Some light precipitation is possible late Wed, potentially ending as a brief period of non- accumulating to trace light snow Thurs morning. The 12z/13 models continue to advance a faster, drier solution for the mid to late week system. A potent northern stream shortwave will dig south from the Ohio Valley into the northern mid- Atlantic late Wednesday through Thursday, as a dampening southern stream shortwave traverses the Gulf coast. Models continue to agree that our area will be sandwiched between the two streams in the moisture deprived region. QPF totals remain very low with just a few hundredths of an inch as most moisture gets hung up on the Appalachian mountains or pulled towards the southern stream, resulting in the colder air chasing the moisture which this pattern rarely results in tangible snowfall. A few light showers are possible with the cold front Wed afternoon/evening. With this, any snow on the tail end of the precip Thurs morning will only produce up to a trace amount. Will note, the 12z/HRRR depicts cooler air moving in faster, which would allow for more accumulating snowfall, but this type of system continuously brings the colder air slower (which was observed with the last system), so there`s very low confidence in the HRRR at this point. KEY MESSAGE 3...Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. Behind the strong Arctic cold front Wed/Thurs, strong CAA will bring below average temperatures and breezy/windy conditions. Highs Thurs and Fri will be in the 30s to lower 40s. Low temperatures will be the coldest Thursday night in the mid teens, additionally with near single digit wind chills. Will need to monitor this for any potential Cold Weather Advisories. The next pair of cold fronts will cross the local area Sat/Sun as an upper level trough remains over the eastern CONUS. These fronts once again look to carry little moisture to the area as they progressively moves towards the East Coast, unable to tap into any southern stream moisture. Models have trended slightly drier with now only slight PoPs (15-20%) during the day Sat and again on Sun. Another round of cold temperatures behind the fronts will bring below average temperatures with highs in the 30s and lows in the teens to low 20s. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... As of 550 PM EST Tuesday... VFR conditions prevail across all terminals through the 00z/14 TAF period. Mainly clear skies are present across the area currently, with FEW- SCT high clouds moving into the northern portions. W/SW winds around 10 kt will continue through the period. Additionally, some low- level wind shear is expected this evening into early Wednesday morning, especially at RIC and SBY, as a weak LLJ is positioned over the northern half of the area. SCT- BKN high clouds will return across the entire area Wednesday morning with the cloud shield from the next approaching low pressure system to the north and associated cold front. Outlook: The cold front will cross the local area Wednesday evening through early Thursday with some light rain showers possible. A brief period of sub-VFR conditions will be possible early Thu morning, as a secondary front crosses the region, ushering in a much colder airmass for the late week period into the weekend. && .MARINE... As of 300 PM EST Tuesday... Key Messages: - SCA conditions are expected tonight into early Wednesday morning due to elevated SW winds. - A strong cold front crosses the area Wednesday night, bringing strong NW winds Wednesday night through Thursday night. High end SCA or low end Gale conditions are likely. - Tidal anomalies remain low for the foreseeable future. Latest surface analysis depicted high pressure offshore with a strong area of low pressure over the N Great Lakes. SSW winds were generally 10-15 kt with gusts up to 20 kt across the coastal waters. The aforementioned low moves E tonight while high pressure continues to slide offshore. This will result in a tightening pressure gradient, aided by a strengthening SW low-level jet, tonight into Wed morning. SW winds increase to 15-20 kt on the Chesapeake Bay with the potential for 20-25 kt sustained winds over the coastal waters N of Parramore Island. Gusts up to 25-30 kt are also expected across the coastal waters. As such, SCAs remain in effect across the Ches Bay and coastal waters north of Cape Charles Light tonight into early Wed morning. The only change was to start all SCAs at 6 PM this evening. SW winds remain elevated (but below SCA criteria) Wed into Wed evening ahead of the strong cold front. A strong cold front is expected to move through the region Wed night as the area of low pressure continues to move E into New England, with another low likely forming in New England to the S of the parent low. This front will bring an abrupt wind shift to the NW, along with a substantial increase in the wind speeds to 20-25 kt with gusts up to around 30 kt for most of the local waters. These elevated winds likely persist into Thursday night as CAA maximizes. High-end SCA to low-end Gale conditions are expected given the strength of the CAA. Will note that the HRRR and ARW show Gale conditions immediately behind the front which may need to be covered by an SMW (if short in duration) or Gale Warning (if longer in duration). Wind probs for 34 kt have increased to 30-45% across the portions of the middle Bay early Thu morning but remain <10% for the rest of the Ches Bay and most of the coastal waters (15-35% across the N coastal waters). As such, confidence was too low to issue Gale Warnings at this time. However, if the trend for higher winds continues, a Gale Warning may be warranted for a portion of the local waters (greatest chance across the N waters). Winds quickly subside around sunrise Friday morning before elevated SW flow returns late Fri afternoon into Sat morning ahead of another cold front with SCAs likely. The current model consensus pushes this front through Sat night with additional SCA headlines possible as winds become W/NW into early next week. Seas were 2-3 ft this afternoon with 1-2 ft waves in the bay. Seas and waves build to 3-5 ft and 2-3 ft respectively tonight through Wednesday morning. Elevated seas and waves return Wed night and continue into Thu night in the wake of the cold front. Tidal anomalies remain low for the foreseeable future. Tides generally trend lower by the 17th (Sat) with low water (and Low Water Advisories) possible across much of the coastal locations. The best chance for low water is across the lower Ches Bay, James River, York River, and the Atlantic coast. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.

Updated at 556 PM EST Tue Jan 13 2026 - Occasional showers continue tonight, favoring east coast metro areas. - Another strong cold front could drop across the peninsula on Thursday, bringing reinforcing cold air and more increased rain chances. && .UPDATE... Issued at 1210 PM EST Tue Jan 13 2026 Overcast skies and light shower activity continues through this afternoon and potentially the evening as well due to a lingering frontal boundary to the south over the Florida Straits. This is leading to cloudy skies and stratiform rain over SE Florida. Rainfall rates are very light, so no major hazards will occur. High temperatures will struggle to rise given the ample cloud cover and light rain, likely only reaching the low to mid 70s for most areas, but especially for the east coast metro. && .SHORT TERM... (Today through Wednesday) Issued at 300 AM EST Tue Jan 13 2026 Latest ensembles and global model solutions show a decaying sfc boundary lingering over SoFlo today, and maybe lifting a little northward. This will require keeping some POPs through early this evening, 20-30 percent, favoring the eastern side of SoFlo. 00Z MFL sounding and model data keep PWATs in the 1.3-1.5" range, for which potential for isolated rainfall amounts of 1" still remains in the forecast. By Wednesday, models show a mid lvl shortwave feature moving around the base of a deepening trough over the SE CONUS. Both systems are shown migrating eastward, with overall synoptic flow veering more southwestward/westward by the afternoon hours. This will further focus highest chances of rain over the Atlantic coastline and around the Broward/Palm Beach metro areas. Meanwhile, a more robust sfc cold front will be pushed southward towards northern Florida by late Wednesday. High temperatures for the short term should remain in the upper 70s to near 80, with overnight lows tonight mainly in the low 60s, with some mid 60s around the east coast metro areas. && .LONG TERM... (Wednesday night through Monday) Issued at 300 AM EST Tue Jan 13 2026 Model consensus depict a FROPA reaching the area on Thursday, with rain chances increasing in the Wed night-Thu morning time frame ahead of the front. Latest timing with this feature places the best chances of showers during the mid/late morning hours on Thursday with scattered to numerous showers possible. In general, dynamic support seem to remain poor as the parent trough/low complex will continue to pull NE into the eastern seaboard. And with prevailing cloud cover, the daytime heating component should remain weak enough to keep mention of thunderstorms out of the forecast attm. This, however, will continue to be revised and updated as necessary. 50-70 POPs remain in the forecast for Thursday morning. Winds veer northward Thursday night into Friday as broad high pressure spreads across the SE CONUS, triggering another cold/dry air advection event. Coldest temperatures with this robust cold air mass are expected Friday morning before sunrise, with coastal areas dropping into the upper 30s to mid 40s, and interior/northern areas in the low-mid 30s. Friday afternoon will also remain fairly cool for being SoFlo, with highs struggling to hit the mid-upper 60s. Temperatures then gradually warm up during the weekend, but still remaining around the low 70s in general. Then by Monday, models seem to suggest another possible cool down with a front approaching the area. There is still a lot of uncertainty in long range guidance, so the forecast philosophy beyond the weekend will continue to be updated with new guidance. && .AVIATION...

Issued at 308 PM EST Tue Jan 13 2026 - Today, a couple degrees warmer with isolated showers, mainly Cape Canaveral southward. - Strong cold fronts arrive Wednesday night into Thursday morning, bringing a brief increase in rain chances. - Below normal temperatures Thursday onward; sub-freezing morning lows and frigid wind chills in the 20s to 30s, especially Friday morning and next Monday morning. && .DISCUSSION... Issued at 308 PM EST Tue Jan 13 2026 Rest of Today-Tonight...Florida remains under weak surface high pressure between a stationary front draped across the Florida Straits to our south and a deep low pressure system tracking across the eastern US to our north. Moisture in proximity of the stationary front extending into Central Florida and a weak surface trough lingering right along/off the Atlantic coast are producing lots of cloud cover, and even a few light sprinkles this afternoon. Through the rest of the evening and overnight, the trough and front are forecast to gradually consolidate into a weak surface low that will begin to lift north-northeastward, dragging higher moisture over the area. Very low (20% or less) rain chances this afternoon gradually increase northward, topping out at 20-30% inland late tonight/early Wednesday morning, before shifting offshore as drier air starts to get wrapped behind a developing weak cool front. Can`t rule out a lightning storm across the Treasure Coast counties and maybe southern Brevard. Afternoon highs up a bit but still in the U60s-M70s. Overnight lows up to he L50s-M60s. Wednesday-Thursday...The weak surface low will continue to lift northeastward, pulling the attendant NNE-SSW oriented cool front draped across the southeast Florida peninsula in the morning offshore by the afternoon. Cool air advection in westerly flow behind this boundary subtly brings temperatures down a bit across most of the area, with Wednesday afternoon highs in the M60-L70s for all but the Treasure Coast counties who remain in the M-U70s. The low early morning rain chances (20-30%) push offshore as the drier and cooler air filters in. There is a low (around 20%) chance for a lightning storm to develop over the Treasure Coast counties, and the nearby Atlantic waters. Some gusty conditions possible Wednesday afternoon with 10-15 mph winds. A slug of very chilly air by way of a pair of cold fronts then pushes into Florida, with the first front arriving Wednesday night, followed by the stronger reinforcing front arriving Thursday morning. Some moisture recovery is expected in proximity of the first front (PWATs down to below 1" in places Wednesday afternoon increasing to 1.25-1.35" overnight), which combined with ample forcing will support areawide 40-60% rain chances Wednesday evening into Thursday morning. However, instability for deep convection is virtually non-existent (MUCAPE only 200 J/kg at best across the southern counties), and as a result lightning storms aren`t expected. There is still some degree of uncertainty when and how much rain locations will receive. General CAMs consensus and HREF has rounds of showers pushing through between 7 PM Wednesday and 9 AM Thursday, but could see showers get started as early as 4 PM pretty much anywhere, and linger into the late morning across the southern counties. QPF also runs the gambit. HREF 24-hour max falls short of half an inch, which is inline with a very dry GFS at around 0.10" in the operational and 0.10-0.25" 90th percentile in the ensemble. The ECM is a little more optimistic at 0.20-0.40" in the operational and up to around 0.60" 90th percentile in a band across the northernmost counties in the ensemble. Overall the rainfall assessment looks to be most places will get 0.10" or less, while a few lucky spots receive up to around 0.50". Temperatures drop a bit Wednesday night, back down into the U40s-U50s, then plunge Thursday between the arrival of the second front and cloudy skies. Afternoon highs forecast to remain chilly in the U50s north of I-4, struggle to make it to the 60s along the corridor, and only reach the 60s to the south. Breezy northwesterly winds (approaching 15 mph with gusts up to 25 mph) will add some bite to the cool Thursday temperatures. Friday-Monday...Before stepping outside for work or school Friday morning, be sure to dress warmly! Forecast morning lows have not changed much from the previous cycle, maintaining the prospect of temperatures at or below freezing along and north of I-4, in addition to sub-freezing lows across interior ECFL as far south as Lake Okeechobee. Making it feel even colder will be a northwest breeze, sending wind chill values into the mid/upper 20s for a majority of the area. As a result, a Cold Weather Advisory will be needed for a large portion of ECFL Friday morning. Winds decrease through the day Friday into early Saturday as high pressure builds over the peninsula behind the fronts. Despite plenty of sun Friday afternoon, temperatures will really struggle to get out of the 50s from Osceola/northern Brevard and points north (low 60s south). Mostly clear conditions Friday night sets the stage for another cold night (30s-mid 40s). With lighter winds overnight, there is a possibility of frost developing Saturday morning over portions of the area. Daytime temperatures make a comeback, climbing into the 60s to low 70s. But then... Below normal temperatures look to be reinforced by another cold front Saturday night into Sunday. A lack of moisture along this front is keeping rain chances out of the forecast. Temperatures swing colder again Sunday into early next week, with lows in the 30s to mid 40s and highs only in the 50s and 60s. Sub-freezing temps are possible again, especially Monday morning. Behind the front, northwest winds will again add a wind chill factor with values falling into the mid 20s to low 30s Monday morning. && .MARINE... Issued at 308 PM EST Tue Jan 13 2026 Rest of Today-Wednesday...Generally favorable ableit a bit rainy boating conditions nearshore forecast through the day Wednesday. A weak low pressure system developing from a surface trough near the Atlantic coast and a stationary front draped over Florida Straits lifts into portions of the peninsula and local Atlantic waters tonight, then pushes well offshore by Wednesday evening. Winds will be shifty at 5-10 kts until the system departs, becoming westerly 10-15 kts nearshore and 15-20 kts (briefly over 20 kts in the afternoon) offshore Wednesday. Small craft should exercise caution offshore Wednesday. Rain chances 20% or less this afternoon gradually increase to 20-30% early Wednesday morning as higher moisture lifts into the area with this system, then decrease through the rest of the morning and afternoon as it departs. An isolated lightning storm mainly across the southern waters and coast can`t be ruled out. Seas 2-4 ft. Wednesday Night-Saturday...Boating conditions deteriorate Wednesday night and Thursday as a pair of strong cold fronts quickly push through Florida and the local Atlantic waters. Westerly winds 10-20 kts early Wednesday night shift northwesterly and increase to 15-25 kts by Thursday morning, then further increase to 20-30 kts Thursday evening, before settling down to 10-15 kts from the north by Friday morning. Seas build to 3-5 ft across the waters by Thursday morning, then jump to 7-10 ft offshore, possibly higher in the Gulf Stream Thursday night. Seas subdued closer to shore by the offshore wind component, but still building to 4-7 ft. Seas subside through Friday, settling to 2-5 ft Friday night. Boating conditions briefly more favorable Saturday before another cold front. Scattered to numerous showers and isolated lightning storms possible Wednesday evening through Thursday afternoon, then dry conditions. && .AVIATION...

| #1257088 (Received by flhurricane at: 3:21 PM 13.Jan.2026) AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 307 PM EST Tue Jan 13 2026 .WHAT HAS CHANGED... The model trends continue to agree on a more progressive (faster) and drier solution for the late week system. No accumulation to trace amounts of winter precipitation is expected Thursday morning. && .KEY MESSAGES... 1) Remaining dry and mild through Wednesday with a light breeze. 2) Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thurs. Some light precipitation is possible late Wed, potentially ending as a brief period of non- accumulating to trace light snow Thurs morning. 3) Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. && .DISCUSSION... As of 300 PM EST Tuesday... KEY MESSAGE 1...Remaining dry and mild through Wednesday with a light breeze. Strong surface high pressure (~1028 mb) to the south and southwest dominates the local weather today with mostly sunny skies and temperatures generally in the mid 50s as of the time of writing. Temperatures have begun overachieving slightly as SSW winds allow a warmer airmass over the area. High temperatures will likely be a few degrees above current obs in the upper 50s to near 60F in the SE VA/NE NC. Despite remaining mostly clear tonight, temperatures will be more mild than last night with lows in the mid to upper 30s. Mid to high clouds will increase Wednesday ahead of the next cold front, but SSW flow will remain, keeping temperatures mild with highs in the mid to upper 50s (lower 50s for the Eastern Shore). KEY MESSAGE 2...Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thurs. Some light precipitation is possible late Wed, potentially ending as a brief period of non- accumulating to trace light snow Thurs morning. The 12z/13 models continue to advance a faster, drier solution for the mid to late week system. A potent northern stream shortwave will dig south from the Ohio Valley into the northern mid- Atlantic late Wednesday through Thursday, as a dampening southern stream shortwave traverses the Gulf coast. Models continue to agree that our area will be sandwiched between the two streams in the moisture deprived region. QPF totals remain very low with just a few hundredths of an inch as most moisture gets hung up on the Appalachian mountains or pulled towards the southern stream, resulting in the colder air chasing the moisture which this pattern rarely results in tangible snowfall. A few light showers are possible with the cold front Wed afternoon/evening. With this, any snow on the tail end of the precip Thurs morning will only produce up to a trace amount. Will note, the 12z/HRRR depicts cooler air moving in faster, which would allow for more accumulating snowfall, but this type of system continuously brings the colder air slower (which was observed with the last system), so there`s very low confidence in the HRRR at this point. KEY MESSAGE 3...Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. Behind the strong Arctic cold front Wed/Thurs, strong CAA will bring below average temperatures and breezy/windy conditions. Highs Thurs and Fri will be in the 30s to lower 40s. Low temperatures will be the coldest Thursday night in the mid teens, additionally with near single digit wind chills. Will need to monitor this for any potential Cold Weather Advisories. The next pair of cold fronts will cross the local area Sat/Sun as an upper level trough remains over the eastern CONUS. These fronts once again look to carry little moisture to the area as they progressively moves towards the East Coast, unable to tap into any southern stream moisture. Models have trended slightly drier with now only slight PoPs (15-20%) during the day Sat and again on Sun. Another round of cold temperatures behind the fronts will bring below average temperatures with highs in the 30s and lows in the teens to low 20s. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... As of 1250 PM EST Tuesday... VFR conditions prevail across all terminals through the 18z/13 TAF period. Clear skies across the area currently, with FEW-SCT high clouds moving into the northern portions later this afternoon. W/SW winds around 10 kt will continue through the period, with RIC seeing some gusts to 15-20 kt this afternoon. SBY may see some gusts to 15- 20 kt after 00z/14. Additionally, some low-level wind shear is likely this evening into Wednesday afternoon, especially at RIC, ahead of the next passing cold front. SCT-BKN high clouds will return across the entire area Wednesday morning with the cloud shield from the next approaching low pressure system to the north and associated cold front. Outlook: The cold front will cross the local area Wednesday evening through early Thursday with some light rain showers possible. A brief period of sub-VFR conditions will be possible early Thu morning, as a secondary front crosses the region, ushering in a much colder airmass for the late week period into the weekend. && .MARINE... As of 300 PM EST Tuesday... Key Messages: - SCA conditions are expected tonight into early Wednesday morning due to elevated SW winds. - A strong cold front crosses the area Wednesday night, bringing strong NW winds Wednesday night through Thursday night. High end SCA or low end Gale conditions are likely. - Tidal anomalies remain low for the foreseeable future. Latest surface analysis depicted high pressure offshore with a strong area of low pressure over the N Great Lakes. SSW winds were generally 10-15 kt with gusts up to 20 kt across the coastal waters. The aforementioned low moves E tonight while high pressure continues to slide offshore. This will result in a tightening pressure gradient, aided by a strengthening SW low-level jet, tonight into Wed morning. SW winds increase to 15-20 kt on the Chesapeake Bay with the potential for 20-25 kt sustained winds over the coastal waters N of Parramore Island. Gusts up to 25-30 kt are also expected across the coastal waters. As such, SCAs remain in effect across the Ches Bay and coastal waters north of Cape Charles Light tonight into early Wed morning. The only change was to start all SCAs at 6 PM this evening. SW winds remain elevated (but below SCA criteria) Wed into Wed evening ahead of the strong cold front. A strong cold front is expected to move through the region Wed night as the area of low pressure continues to move E into New England, with another low likely forming in New England to the S of the parent low. This front will bring an abrupt wind shift to the NW, along with a substantial increase in the wind speeds to 20-25 kt with gusts up to around 30 kt for most of the local waters. These elevated winds likely persist into Thursday night as CAA maximizes. High-end SCA to low-end Gale conditions are expected given the strength of the CAA. Will note that the HRRR and ARW show Gale conditions immediately behind the front which may need to be covered by an SMW (if short in duration) or Gale Warning (if longer in duration). Wind probs for 34 kt have increased to 30-45% across the portions of the middle Bay early Thu morning but remain <10% for the rest of the Ches Bay and most of the coastal waters (15-35% across the N coastal waters). As such, confidence was too low to issue Gale Warnings at this time. However, if the trend for higher winds continues, a Gale Warning may be warranted for a portion of the local waters (greatest chance across the N waters). Winds quickly subside around sunrise Friday morning before elevated SW flow returns late Fri afternoon into Sat morning ahead of another cold front with SCAs likely. The current model consensus pushes this front through Sat night with additional SCA headlines possible as winds become W/NW into early next week. Seas were 2-3 ft this afternoon with 1-2 ft waves in the bay. Seas and waves build to 3-5 ft and 2-3 ft respectively tonight through Wednesday morning. Elevated seas and waves return Wed night and continue into Thu night in the wake of the cold front. Tidal anomalies remain low for the foreseeable future. Tides generally trend lower by the 17th (Sat) with low water (and Low Water Advisories) possible across much of the coastal locations. The best chance for low water is across the lower Ches Bay, James River, York River, and the Atlantic coast. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.

The first upper trough will reach its strongest and become highly amplified late Wednesday night, and the second reaching its strongest, becoming medium amplified, around midnight Saturday night. The first trough will feature an associated surface low pressure area moving across southeast Canada by midweek, sending an associated strong cold front through the northern/central Plains and Upper Midwest. This front will continue to move rapidly toward our region on Wednesday and sweep through our area from late Wednesday afternoon through mid- evening. The second trough will feature an associated surface low pressure area slightly further south and move across the northern Great Lakes on Friday and Saturday, sending an associated strong cold front through the northern/central Plains and Upper Midwest Thursday and Thursday night. This front will continue toward our region and pass through our area Saturday morning. A Clipper System diving southeast across the northern Plains and Upper Midwest Saturday night through Sunday afternoon will send a reinforcing cold front through our area Sunday morning. Isolated to scattered light showers are possible late Tuesday night into early Wednesday morning as the upper trough approaches our region and deepens. Isolated to scattered light showers are also possible north of Highway 84 Wednesday afternoon and east of the Tombigbee River Wednesday evening ahead of the cold front. Very little moisture will return ahead of the weekend system, so we are expecting dry weather conditions. That said, there is a small potential of a few flurries late Wednesday night and late Saturday night with the passing of the two surface cold fronts. High temperatures will be near normal Wednesday in the middle 50s and lower 60s before we enter into the arctic airmass, with highs Thursday ranging from 44-49 degrees. Lows Thursday night should fall into the middle to upper 20s inland, with lower 30s along the immediate coast. These high and low temperatures are about 10 to 15 degrees below normal. The apparent temperatures Thursday and Friday mornings in the lower to middle 20s inland and the middle to upper 20s closer to the coast are expected to remain just above cold weather advisory criteria. After a quick moderation in temperatures on Friday, sub-freezing overnight lows are expected again Saturday and Sunday nights in the wake of the second cold front. Beach Forecast: A LOW risk of rip currents will occur through Wednesday afternoon, briefly becoming MODERATE Wednesday night for the Florida beaches. A LOW risk of rip currents will follow through the remainder of the week. /22 && .AVIATION... (18Z TAFS) Issued at 1115 AM CST Tue Jan 13 2026 VFR conditions expected the rest of the day through the evening. A passing system is expected to bring local drops to MVFR levels late tonight into Wednesday morning, Easterly winds of 5 to 10 knots this afternoon will shift to southerly overnight, then westerly Wednesday morning. /16 && .MARINE... Issued at 155 PM CST Tue Jan 13 2026 A Small Craft Advisory (SCA) has been issued for our entire area starting Wednesday night due to a strong cold front passes through the region. This SCA will remain in effect for the coastal waters of Alabama and northwest Florida until 9 AM Thursday, the coastal waters out 20 NM until noon, and from 20 to 60 NM until 6 PM. Prior to the arrival of the front, mariners operating small craft on the Gulf should exercise caution Wednesday afternoon due to a moderate westerly flow. Behind the front, offshore flow will gradually decrease Thursday afternoon through the overnight hours, becoming a light onshore flow on Friday. A light to moderate westerly flow Friday night will shift northwesterly on Saturday in the wake of the next cold front. /22 && .PRELIMINARY POINT TEMPS/POPS...

Issued Cape Lookout to Surf City to the Small Craft Advisory from Wednesday evening through Thursday night. Extended the Small Craft Advisory for Oregon Inlet to Cape Lookout through Thursday night. Probabilities for Gale Force winds has decreased for Thursday night. && .KEY MESSAGES... 1) A low pressure system and cold front Wednesday through Thursday night will bring the next chance of rain, with a slight chance of non-accumulating snow Thursday morning. Strong CAA behind the front will bring wind chill values in the teens Thursday night into Friday morning. 2) A system with limited moisture moves through Sunday, with another surge of cold, dry air behind it. MARINE: SCA conditions Wednesday through Thursday night. SCA conditions possible again for the weekend. && .DISCUSSION... KEY MESSAGE 1... A robust northern stream trough digs into the eastern CONUS today through Wednesday. An embedded shortwave moving across the Deep South will bring improved upper level forcing and expect an area of low pressure to develop off the Southeast coast Wednesday which will pass off the NC coast Wednesday evening. There continues to be some uncertainty with the exact track of the low offshore which will ultimately determine precip coverage and amounts across the region. The best precip chances continue to be along OBX and areas offshore where we continue likely PoPs, which tapers to slight chance well inland. Guidance remains limited with precip amounts which shows around a quarter of an inch along the OBX to little accumulation inland. All liquid precip expected through Wednesday evening. A second shortwave moves through the upper trough Wednesday night with an attendant cold front pushing across ENC early Thursday morning. ENC is removed from best upper level dynamics but sufficient moisture lingers that we could see a brief change over to a rain/snow mix or snow with strong CAA developing behind the front Thursday morning. This will be a typical cold air chasing the moisture, likely keeping us dry Thursday afternoon except possibly for the immediate coast. Additional rainfall amounts will only be a few hundredths of an inch liquid with no snow accumulation expected. The upper level trough axis pushes across the region Thursday evening bringing descent forcing but by this time moisture will be quite limited. Strong CAA continues Thursday night bringing breezy conditions and temps dropping to around 20 inland and mid to upper 20s along the coast, which will result in wind chill values in the teens Thursday night into Friday morning. KEY MESSAGE 2... A deep upper level trough with an associated cold front is expected to move through the region early Sunday. There isn`t much moisture to play with ahead of this front, so precip chance is on the lower side (PoPs 15-20%) and mainly near the coast. NBM called for snow chances, but with sfc temps in the 40-45F range at that time, paired with the drier trend, elected to stick with all rain for the forecast. Cyclonic flow continues aloft early to mid next week with additional dry fronts/troughs pushing across the region keeping temps well below normal with highs generally in the 40s and lows in the 20s, though could see upper teens in coolest inland spots. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... VFR conditions expected through the TAF period as high pressure builds in from the southwest. Southwesterly winds 5-10 kts this afternoon will diminish to 5 kts or less overnight, then remain light southerly on Wednesday. Clouds increase late in the TAF period ahead of an approaching cold front. Outlook: Predominant VFR flight conditions expected through much of the period with high pressure in control. An area of low pressure and cold front will cross through Eastern NC on Wednesday and Thursday, which could produce lowered ceilings and visibilities (MVFR), and light precipitation, which may briefly mix with some snow before ending on Thursday. High pressure returns for Friday into the weekend. && .MARINE... Currently seeing WSW winds less than 15 kt and seas around 2 ft across the waters this afternoon. Will see some strengthening of the winds as a low crosses the Great Lakes and high pressure sits offshore, tightening the pressure gradient. This will bring frequent gusts around 25 kts for the warmer Gulf Stream waters tonight. Winds diminish a bit to around 15-20 knots Wednesday before picking back up to 20-30 knots Wednesday night as a low forms offshore and strengthens. Again, best chance of seeing Small Craft gusts with this low is along warmer Gulf Stream waters with SW flow. Cooler inland sounds/rivers will see much lighter wind gusts with the SW winds thanks to a marine inversion. A cold front will push across the waters Thursday morning with strong CAA developing Thursday afternoon and Thursday night and could see NW winds bring strong SCA conditions across the waters. Guidance is a little weaker with post frontal winds and NBM probs for Gale Force gusts are below 25%. Continue the SCA for Gulf Stream waters for frequent gusts but have extended through Thursday night given the lower probs for Gales. Conditions improve late in the week with high pressure briefly building into the area. This weekend, another cold front moves through, bringing elevated winds and seas once again. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.

No significant changes have been made to the forecast. && .KEY MESSAGES... - Period of showers late tonight across interior southern New England, with some snow showers confined to the very highest terrain. - Mild weather Wed into Wed night. A few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. - Turning colder Thu with falling daytime temps. Dry and cold Thu night-Fri. Lows Thu night in the upper single digits and teens with highs Fri mainly in the upper 20s and lower 30s. - Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun, but a significant storm is unlikely. && .DISCUSSION... KEY MESSAGE 1...Period of showers late tonight across interior southern New England, with some snow showers confined to the very highest terrain. Still a risk for some showers tonight, but thinking the primary focus is shifting north of our region, closer to the low pressure north of the Great Lakes. Given the relatively weak lift and mostly dry lower levels across our region, not expecting much precipitation. The primary window of concern is between about 10 PM-4 AM. As warm as we are, expecting mainly rain for the most likely type, with perhaps snow light snow across the higher elevations of the Berkshires and far northern Worcester Hills towards the NH border. KEY MESSAGE 2...Mild weather Wed into Wed night. A few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. A potent mid level shortwave should amplify a mid level trough to our west Wednesday night. This in turn will continue to boost temperatures across southern New England Wed into Wed night. Expecting temperatures some 10-15 degrees above normal during this time. Some locations across RI and eastern MA could make a run at highs of 50F Wednesday. Rainfall should be the main precipitation type given these temperatures. An approaching cold front late Wednesday night could lead to some snowfall mixing in across the Berkshires after midnight. By daybreak Thursday, it`s possible that some light snow could expand as far east as the Worcester Hills. Little snow accumulation is expected. KEY MESSAGE 3...Turning colder Thu with falling daytime temps. Dry and cold Thu night-Fri. Lows Thu night in the upper single digits and teens with highs Fri mainly in the upper 20s and lower 30s. As the low pressure lifts into Northern New England on Thursday a cold front swoops in ushering in a colder and drier airmass into SNE. There`s still some question as to how quickly that cold air arrives, so low confidence on who may see some 40s stick around much of the day or not. Either way it will feel colder thanks to winds gusting 20-25 mph late in the day as the pressure gradient tightens between the deepening low and the incoming ridge of high pressure. CAA continues into early Friday with 925mb temps dropping to -15C before rebounding as heights rise toward the weekend. This means one night (Thursday night) of lows in the single digits and low teens. Friday, highs only reach into the 20s with continued breezy winds. KEY MESSAGE 4...Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun, but a significant storm is unlikely. Rising mid level heights are brief as the high pressure quickly moves east and a mid level trough digs into the Great Lakes. This places the region under warm SW flow and we`ll see temps rise back into upper 30s and low 40s Saturday. A weak disturbance moving through may be enough to kick off some widely scattered low elevation rain or high elevation snow showers, but on the whole most locations should be dry. The core of the mid level low passes north into Canada; too soon to nail down exact details on what periods may have a better chance at some wet weather, but we continue to not expect a big storm system over the weekend. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High -greater than 60 percent. Through Tonight...High confidence. Mainly VFR. Very brief MVFR conditions possible across the interior between about 03-09Z in a few brief rain showers. Any snow showers will be confined to the very highest terrain of the Berkshires and northern Worcester Hills and rather short-lived too. Modest LLJ developing will result in periods of SW wind gusts of 20 to 25 knots tonight near and southeast of the I-95 corridor. LLWS included for some terminals given winds at 850 mb on the order of 45 to 55 knots. Wednesday...High Confidence. VFR for most. Areas MVFR and local IFR towards the Berkshires during the afternoon. Low risk for some rain showers as well. Wednesday Night...High Confidence. Mainly VFR to start across the eastern half of southern New England. Areas MVFR with local IFR across the western half expanding east after midnight. Widespread MVFR with IFR across the higher terrain expected towards the Thursday morning push. Chance of rain showers, with snow showers across the higher terrain of the Worcester Hills and Berkshires. More widespread snow showers possible across the western half of southern New England late.

Issued at 253 PM AST Tue Jan 13 2026 * Seasonal conditions will prevail across the region with passing trade-wind showers affecting the windward and coastal areas of Puerto Rico and the U.S. Virgin Islands during the morning and evening hours. * Localized afternoon showers will lead to a limited flooding risk across portions of central and western Puerto Rico each day. * A moderate risk of life-threatening rip currents will continue along the north and east-facing beaches of Puerto Rico, Culebra & St. Croix through the end of the workweek. * Marine and coastal conditions will deteriorate this weekend with the arrival of a northwesterly swell and stronger winds. Residents and visitors are urged to follow the conditions closely as the week progresses. && .Short Term(This evening through Thursday)... Issued at 253 PM AST Tue Jan 13 2026 High-level cloudiness prevailed throughout most of the morning across all the islands, accompanied by light to moderate showers affecting the exposed waters and briefly streaking over the eastern sides of the islands. As of 12 PM, satellite imagery showed the cloudiness development, mostly across the interior into the western interior. Therefore, shower activity developed across those areas with light to moderate shower activity. Rainfall accumulations from the Doppler Radar were minimal, with the highest value in Trujillo Alto at almost half an inch. Daytime temperatures were near seasonal values. According to unofficial stations, temperatures were in the mid- to upper 80s across coastal areas and near the upper 70s and lower 80s in the interior. For the rest of the period, the weather will remain mostly stable as the mid- to upper-level ridge continues to dominate the atmospheric pattern. Meanwhile, at the surface, a strong and broad surface high pressure will continue to result in an easterly wind flow. Under this surface pattern, a patch of shallow moisture will filter in, with Precipitable Water Values of 1.2 inches, as shown by GOES-derived satellite imagery, exceeding climatological normal. These surface conditions will be enough to trigger a variable weather pattern tonight, with occasional showers across eastern sections of Puerto Rico and the U.S. Virgin Islands. Weather conditions will slightly change as the broad surface high pressure extends farther into the western Atlantic and as some influence from the frontal boundary located north of the region. As a result, veering winds will be present, and a southeasterly flow will be predominant on Wednesday into Thursday. Under this wind flow, moisture from the Caribbean will move into the islands, peaking the 850-500 MB Relative humidity at the 75th percentile on Wednesday. Therefore, the forecast calls for a more showery pattern, with frequent showers across eastern sections and afternoon convection across the interior and northwestern parts of Puerto Rico. On Thursday, similar weather conditions will persist, with precipitable water values similar to those moving into the region, but with some instability as a deep-layer trough stalls over the western Atlantic, weakening the ridge over the area. As a result, colder temperatures are expected at 500 MB, with potential for one or two thunderstorms, with the afternoon showers across the interior and northwestern PR. && .Long Term(Friday through next Monday)... Issued at 502 AM AST Tue Jan 13 2026 On Friday, model guidance indicates that a frontal boundary will remain north of the region, while a pre-frontal trough may enhance low-level moisture convergence and atmospheric instability, supporting a wetter pattern. Friday currently appears to have the greatest rainfall potential, with a limited flood risk mainly across western Puerto Rico during the afternoon hours. Isolated thunderstorms cannot be ruled out. Precipitable water values are forecast to range between 1.4 and 1.9 inches from Friday through Saturday, near to above climatological normals for this time of year. Low-level winds will generally remain from the east to southeast at 10 to 15 mph on Friday, then shift to the east to northeast by Friday night into Saturday while increasing to 15 to 20 mph with gusts up to 25 to 30 mph. Breezy to locally windy conditions are expected Saturday and early Sunday, which may lead to loose outdoor items being blown around, especially across exposed and coastal areas. From Sunday through Tuesday, precipitable water values are expected to decrease to between 1.2 and 1.5 inches, with patches of near-average moisture moving across the region. This will support more variable but seasonable conditions, with passing trade wind showers and limited convective development each afternoon. No flooding concerns at this time. A subtropical jet streak near 250 mb will establish a favorable dynamic pattern from Tuesday night into Wednesday, supporting upper-level divergence and an induced surface trough. As a result, an increase in the frequency of showers is expected across the forecast area under a northeasterly low-level wind flow. Continue to monitor the forecast updates. Temperature-wise, ensemble guidance continues to indicate near seasonal to above-normal temperatures across Puerto Rico and the U.S. Virgin Islands throughout the long-term period. && .AVIATION... (18Z TAFS) Issued at 253 PM AST Tue Jan 13 2026 VFR conditions will persist across all TAF sites during the period. VCSH to SHRA will continue near TJSJ, TJBQ & TJPS from now through 13/22Z. Winds will persist from the E-NE up to 11 knots with sea breeze variation, diminishing at 14/03Z./ Hi-Resolution models show an increase in shower activity across the eastern TAF sites from 13/23Z to 14/12Z. No significant operations are forecast. && .MARINE... Issued at 253 PM AST Tue Jan 13 2026 A surface high pressure across the central Atlantic and a surface trough to the north of the region will maintain gentle to moderate east to northeast winds through Wednesday, then shifting from the east to southeast by Thursday. This pattern will support passing trade- wind showers, mainly across the Atlantic waters, with occasional showers also moving through the Caribbean passages. By Saturday, strengthening east to northeast winds and the arrival of a long- period northerly swell will likely result in choppy to rough seas, leading to hazardous marine conditions during the weekend. Mariners are advised to continue monitoring the forecast. && .BEACH FORECAST... Issued at 253 PM AST Tue Jan 13 2026 A moderate risk of rip currents will continue for the next several days along the northern and eastern beaches of Puerto Rico, as well as Culebra and St. Croix, with breaking waves around 4 feet. A moderate risk means that life-threatening rip currents are possible within the surf zone, and beachgoers should exercise caution at all times. Conditions are likely to deteriorate over the weekend as winds increase and the arrival of a long-period northerly swell. This will lead to a high rip current risk across Atlantic exposed beaches of Puerto Rico and the U.S. Virgin Islands.

Strong post-frontal winds have trended a bit weaker on Thursday, and the probability for a Lake Wind Advisory on Thursday afternoon has diminished. A fourth key message was added to cover the concerns for this upcoming weekend. && .KEY MESSAGES... 1) High pressure over the region will keep conditions dry through the remainder of the day, with relative humidity values dropping to low levels this afternoon. 2) Dangerous fire weather and marine conditions possible Thursday into Friday as gusty post-frontal winds combine with low humidity. 3) Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. 4) Dry and cooler temperatures for the second half of the weekend into early next week. && .DISCUSSION... KEY MESSAGE 1: High pressure over the region will keep conditions dry through the remainder of the day, with relative humidity values dropping to low levels this afternoon. Dry surface high pressure will continue to dominate the forecast across the Southeast today. As of 1630Z, observations have been showing dewpoints in the mid 20s to upper 20s range with some locations showing values in the low 30s. Weak southwest flow will yield dewpoints in the mid 30s by the afternoon, spreading inland from the coastline. Minimum RH values will occur in the afternoon hours, prior to dewpoint recovery. Forecast min. relative humidity values will fall into the mid to upper 20 percent range west of I- 95, with low to mid 30 percent range and and east of I-95. High temperatures are forecast to range around 10 degrees warmer than yesterday, with temps. reaching into the upper 50s to low 60s. KEY MESSAGE 2: Dangerous fire weather and marine conditions possible Thursday into Friday as gusty post-frontal winds combine with low humidity. A rex block will be well-established over the Western CONUS on Thursday, as broad downstream amplified trough exists across the Eastern CONUS. This trough should slowly deamplify as a closed mid- lvl low pushes eastward across the Great Lakes, yielding lower heights out ahead of it. Despite the magnitude of these dropping heights, precipitation chances remain limited (less than 10%) with the approaching surface cold front. This mainly due to location of the LFQ of the subtropical jet streak on Thursday early morning, and most of the precipitation will be located offshore. Post-FROPA conditions will yield strong low-lvl CAA and expect 850 mb temps. to drop from 0C to -8C on Thursday morning. This combined with peak mixing and downslope flow in the low to mid lvls will likely result in breezy northwesterly flow on Thursday afternoon with 20 to 25 mph gusts possible. It`s possible that a Lake Wind Advisory might be needed for Thursday afternoon, however probabilities of winds reaching 25 kt has dropped down to 20-25%. Additionally, expect dewpoints to drop rapidly into the low to mid teens behind the cold front allowing relative humidity values to drop below 30% west of I-95 on Thursday afternoon. It`s important to note that the Wambaw and Glissons Pond RAWS sites have both had fuel moisture values in the single digits on the previous Sunday and Monday afternoons. Walking into Friday morning, surface high pressure will settle across the region and keep dewpoints in the low to mid teens through Friday evening, before dewpoint recovery. The latest LREF probs. indicate 40-50% chance of RH values less than 25% west of I-95. Also of note is that lingering upper lift associated with the strongest DPVA will pass over the area late Wednesday night into Thursday morning, coincident with low-lvl temps well below freezing. Very dry mid to upper-lvl air advecting overhead is very likely to preclude any potential for precip., with cluster analysis revealing that only outlier guidance showing a much greater amplitude upper- lvl trough shows potential for flurries mainly across the Low Country. Take home message here is that we are very likely to remain dry Wednesday night/early Thursday, with the worst case scenario being some brief flurries. KEY MESSAGE 3: Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. There is very good agreement in calm winds emerging as the surface ridge axis builds overhead Thursday evening and overnight. Temps away from the coast drop below freezing within a few hours after sunset, then continue to steadily cool through the night as dew points remain in the lower teens. Lows will likely be in the upper teens inland of US Hwy 17 corridor, and low-to-mid 20s closer to the coast. As such the potential for lows of 20 or less is generally likely (50-80%) inland of the US Hwy 17 corridor, 10-40% along the US Hwy 17 corridor, including much of the inland portions of the Charleston and Savannah Metro areas, and less than 10% for areas near the beaches. Key Message 4: Dry with cooler temperatures for the second half of the weekend into early next week. As an upper level trough moves towards the region, a cold front sweeps through Saturday night into Sunday. Overnight lows dip into the mid 20s to lower 30s for inland areas, and into the mid 30s along the coast. Probabilities for overnight temperatures at or below 20 degrees F are very low, only 10% for interior Georgia. The upper level trough axis pushes through on Sunday, with ensemble clustering showing the majority of solutions keep the region dry given the lack of moisture. If moisture were to become more plentiful, the ptype would largely remain rain given warm thermodynamic profiles, with afternoon highs in the mid 40s to lower 50s. However, the probabilistic Winter Storm Severity Index (WSSI-P) does show a 5-10% chance for a trace of snowfall from the colder solutions, but again moisture looks to be lacking so we most likely won`t see any falling precipitation. Coldest temperatures move down overnight into Monday as a surface high pressure builds into the region, with overnight lows down into the mid 20s for furthest inland areas and up into the lower 30s along the coast. Given a decent radiational cooling set up which may lead to further cooling, probabilities for temperatures at or below 20 degrees are in the 40-50% range for those furthest inland, and down to 5% along the coast. Ahead of the approaching high pressure, winds may remain just strong enough (near 5 knots) where wind chills may dip into the 15 to 20 degrees range, with highest probabilities again for the furthest inland areas right at 50%, dropping to 25% along the coast. A Cold Weather Advisory may be needed. Highs on Monday remain below normal, in the lower to upper 50s. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... VFR conditions prevail at CHS/JZI/SAV terminals through 12Z Wednesday. It`s possible to see flight restrictions Wednesday afternoon as showers develop ahead of the approaching cold front, however confidence remains low with this. Extended Aviation Outlook: VFR conditions Friday. && .MARINE... Broad surface high pressure remains across the marine zones through tonight, yielding 5 to 10 kts and seas between 2 to 3 ft. Conditions remain below Small Craft Advisory criteria through early Thursday morning. A strong cold front will march across the local waters late Wednesday night into Thursday morning, yielding gusty post-frontal northwesterly winds Thursday mid-day through Thursday evening. Expect seas to gradually build to 3 to 5 ft across the nearshore waters with possible 6 footers peaking into the offshore Georgia waters on Thursday afternoon into the evening. Therefore, Small Craft Advisories seem likely for Thursday mid- day into the evening. Expect improved marine conditions for Friday as upper-lvl ridging settles overhead, yielding light to moderate winds and seas mainly 1 to 2 ft. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None.

Issued at 1213 PM CST Tue Jan 13 2026 A weak upper level low over central Texas this afternoon will continue eastward tonight, merging with a broader trough digging across much of the Central/Eastern Conus. We`ve already seen widespread light showers across the region on radar, indicating that PWs of 0.75-1.00 inches have been sufficient with the amount of lift provided by the low. Shower coverage is expected to peak this afternoon (right around now) as we get the full forcing from the passing upper level low. Activity then tapers off from west to east into overnight into Wednesday as the low exists the area. Anticipate another cold evening with lows for Wednesday morning in the 40s/lower 50s. Wednesday kicks off with the aforementioned upper level low, now shortwave, east of the area, now embedded within the much stronger mid/upper trough spanning the Central/Eastern CONUS. This larger upper level feature is anticipated to push a weaker reinforcing front through SE Texas on Wednesday. Winds may briefly shift W/WSW early in the morning due to a prefrontal trough moving in from the north. The reinforcing front should lag behind it, entering the Brazos Valley during the late morning, then moving off the coast during the late afternoon. PWs will be fairly low, generally under 0.75", thus showers will be extremely sparse if any form to begin with. Breezy northerly winds and cooler temperatures should settle in behind the front. Daytime highs may top out in the 60s/lower 70s, but anticipate much cooler temps overnight with lows for Thursday morning in the 30s/40s. A light freeze could occur in many spots across the Piney Woods area near Crockett. Thursday won`t be a particularly active day as we find ourself post- cold front. Surface high pressure should pass over the region during the daytime with breezy northerly winds early in the day becoming light and variable, then later shifting southeasterly in the evening. Daytime highs will be fairly cool as onshore flow is (tentatively) set to occur after peak heating, with highs topping out in the 50s. After onshore flow is resumes, we`ll see moisture slowly return overnight, which should help limit the full extent of cooling overnight. Lows for Friday morning will should be slightly warmer, though still in the 30s/40s across much of the area with some lower 50s along the coast. Friday should see another mid/upper level trough dig through the Northern Mississippi River Valley/Great Lakes. This trough should send another cold front towards SE Texas, which should push into the Brazos Valley during the late afternoon and later off the coast some time around midnight. PWs by this point are forecasted to be around 0.5" or less. Rain chances will be very low with this frontal passage too, but there is still a chance that some light showers could develop along the coast as moisture pools. Highs during the daytime should top out in the 60s/lower 70s. Breezy and cooler air filters in overnight into the early morning hours with lows for Saturday morning ranging from the 30s/40s to possibly lower 50s at the coast. Could see lows touch the freezing mark across the northern edge of our CWA. Saturday on the whole should feature benign, post-frontal weather as high pressure fills in over the region, causing winds to relax and shift northeasterly. Highs should reach the 50s/60s during the daytime. Clear skies aloft from high pressure and with northerly flow still in place, we should see some of the coolest temperatures overnight into Sunday morning with lows in the 30s/lower 40s inland and mid/upper 40s along the coast. Sunday will see surface high pressure move off to the east into the Lower Mississippi River Valley, allowing onshore flow to return during the afternoon. This will usher in WAA and bring gradually warming temperatures and increasing moisture into next week. Highs for Sunday should reach the upper 50s/60s during the daytime. Overnight temperatures will be slightly warmer, but still cool with lowers for Monday morning anticipated to bottom out in the upper 30s/lower 50s. Forecast certainty decrease heading into next week, but signs suggest that we`ll see at least one more afternoon of warmer weather on Monday. Highs are anticipated to reach the the 60s/lower 70s during the daytime, with some isolated showers/storm chances possible during the daytime as PWs climb above 1.0 inch. Long range models suggest that another mid/upper level trough may dig across the Northern Plains/Great Lakes/Ohio Valley on Monday, sending another cold front into SE Texas. Timing is still up in the air, but anticipate the FROPA to occur some time Monday afternoon/evening or early Tuesday Morning. 03 && .AVIATION... (12Z TAF Issuance) Issued at 516 AM CST Tue Jan 13 2026 VFR conditions will prevail with BKN to OVC mid and high level clouds passing through the region. There will be a chance of isolated, light showers developing during the afternoon hours today.

Updated at 1208 PM CST Tue Jan 13 2026 - After today, minimal rain chances until next week - Elevated fire weather conditions Wednesday afternoon behind cold front - Wind chill values in the 30s Thursday and Friday morning && .DISCUSSION... Issued at 1208 PM CST Tue Jan 13 2026 Light rain and virga earlier this morning over South Texas continues to linger in eastern areas early this afternoon. I do expect most if not all of this light rain to come to stop by late this afternoon, with mostly cloudy conditions and light offshore winds limiting highs in the mid 60s. Drier air and mostly clear skies tonight will allow for morning lows to drop into the low-mid 40s and highs to climb into the 70s Wednesday before our next cold front pushes through in the afternoon. Relative humidity values dropping to 20-30% with northerly wind gusts of 20-25 mph and above normal Energy Release Component (ERC) values Wednesday afternoon, will likely result in elevated fire weather conditions across the Brush Country and portions of the inland Coastal Plains. Onshore flow returns briefly Thursday night through Friday, before another cold front moves into South Texas Friday night into Saturday morning. Low confidence on the southern extent of the front, with both ECENS/GEFS showing the front stalling west to east across the CWA while the CMC has the front plow through. Temperatures and any rain chances will be heavily dependent on the location of the front, don`t expect great rain chances with PWAT values just near or slightly below normal. Models are in good agreement with onshore flow and southerly flow aloft returning early next week ahead of a front, bringing PWAT values to the 90-99th percentile and rain chances Monday into Tuesday. Model discrepancies become more apparent with this front and the mid-level low/trough developing off of northeast Canada. Highs into early next week will range from the 60s to 70s and lows in the 40s through the rest of this week, warming into the 50s early next week. && .AVIATION... (18Z TAFS) Issued at 1208 PM CST Tue Jan 13 2026 VFR conditions are prevailing across South Texas, with lingering light rain and virga continuing into this afternoon over the Coastal Plains. Light offshore winds will continue through Wednesday morning, ahead of our next cold front Wednesday afternoon. && .MARINE... Issued at 1208 PM CST Tue Jan 13 2026 A gentle to moderate (BF 3-4) breeze will continue through Wednesday morning. Winds will increase to fresh to strong and shift northerly (BF 5-6) Wednesday afternoon through Thursday morning as another cold front moves across the waters, leading to Small Craft Advisory conditions. Winds will diminish to gentle to moderate (BF 3-4) Thursday afternoon into Thursday night. A gentle to moderate (BF 3-4) southerly breeze returns Friday before another cold front stalls across the area this upcoming weekend, shifting winds out of the northeast and occasionally fresh (BF-5). && .FIRE WEATHER... Issued at 1208 PM CST Tue Jan 13 2026 A cold front will usher in drier air (minimum relative humidity values less than 30%) Wednesday afternoon and continue each afternoon through the end of the week which, when combined with above normal ERC values, could lead to elevated fire weather conditions through the end of the work week. Elevated fire weather conditions are most likely Wednesday afternoon with northerly wind gusts of 20-25 mph. Following, light winds will limit our fire weather threat and keep us well below thresholds for critical fire weather concerns. && .PRELIMINARY POINT TEMPS/POPS...

There is a 60% to 80% chance of showers tomorrow night as the front moves through. The probability of thunderstorms is low. - Hazardous marine conditions are forecast Thursday morning through Friday morning. Winds of 20kts to 30kts with gusts to near gale force (34kts) are forecast. This will create seas up to 10 feet offshore and seas of 4 to 7 feet nearshore. Inexperienced mariners should remain in harbor. - A significant cooldown is forecast late this week. Friday morning will be the coldest, with lows in the 20s and 30s away from the coast, and around 40 degrees along the coast. Plan accordingly, particularly in the overnight and early morning hours when temperatures will be at their coldest. && .SHORT TERM... (This evening through Wednesday) Issued at 119 PM EST Tue Jan 13 2026 A trough axis is centered over the Great Lakes region and stretches south into the Central Plains, becoming increasingly diffuse as weak ridging holds on across the Caribbean and southern Gulf. This is, however, being eroded as a cut-off low propagates eastward across West TX. For now, though, the pattern remains relatively flat and surface high pressure remains in control. Given the surface ridge axis placement well to the East near Bermuda, a return flow has settled across the FL peninsula. Relatively warmer and more moist air is being advected back across the region. With this lower-level moisture this means more clouds and weak low-level instability. A low-topped, quick-passing shower cannot be completely ruled out this afternoon/evening across the southern interior and SWFL given this setup, but most areas should stay dry today. && .LONG TERM... (Wednesday night through next Monday) Issued at 119 PM EST Tue Jan 13 2026 The more impactful weather system arrives late tomorrow and into Thursday morning. The cut-off low over TX is absorbed by the flow as the trough over the Great Lakes digs into the SE and becomes positively tilted. This will usher in a strong cold front to the region. Ahead of the front, showers are forecast to develop across Gulf waters and move onshore. Some of these showers could have some gusty winds - but the overall potential for lightning is low given the weak (-5C) low-level lapse rates. It`s just not a very rapidly cooling atmosphere in the layer where the deeper moisture lies. However, the strong frontal system will drive a steep pressure gradient and thus favor gusty winds. These will begin to increase as the front approaches, but will become stronger once the front passes. Wind gusts over coastal waters could approach gale force (34kts). Friction over land favors wind gusts of 20 to 25 kts. Colder air then filters in behind the frontal passage, with several chilly days in store. The coldest day in the forecast currently looks to be Friday. Lows will generally be in the 20s and 30s, except right at the water where temperatures will be closer to 40 degrees due to the relatively warmer water. Gradually, temperatures then begin to warm up through the weekend as high pressure settles east and the low-level flow veers to more of a southerly direction. However, meridional flow stays dominant in the upper-levels, which means another trough and associated frontal boundary will arrive in the area early next week. This will hold temperatures down, and favors some additional cooling early next week. Currently, next Monday is also looking pretty similar temperature-wise to how Friday will be this week. Gradual warming then resumes towards the middle of next week. && .AVIATION... (18Z TAFS) Issued at 119 PM EST Tue Jan 13 2026 The only significant aviation concern over the next 24 to 30 hours is for MVFR to perhaps even IFR conditions due to low CIGs. There is a low (less than 20%) probability of a shower after 18Z tomorrow for Tampa Bay area terminals. Probabilities for showers will then increase overnight Wednesday into Thursday as the next front approaches. A period of MVFR to even IFR weather will also accompany these showers before conditions gradually improve through Thursday. However, gusty winds should be expected during the day Thursday, before gradually improving Thursday night and into Friday. && .MARINE... Issued at 119 PM EST Tue Jan 13 2026 Marine conditions will begin deteriorating late tomorrow as the next cold front approaches. Some storms are forecast across coastal waters, with some locally hazardous marine conditions possible in the vicinity. However, winds begin to increase significantly behind the front, with gusts to near gale force possible on Thursday. This favors dangerous seas of up to 10 feet offshore and 4 to 7 feet nearshore. Inexperienced mariners should remain in port until conditions improve. Winds then begin to settle Thursday night and into Friday, with improving marine conditions Saturday before gradually increasing again as the next front approaches late in the weekend and early next week. && .FIRE WEATHER... Issued at 119 PM EST Tue Jan 13 2026 No significant fire weather concerns through tomorrow with ample moisture and light winds to preclude any red flag concerns. The next front arrives overnight Wednesday and into Thursday, with the potential for some rain across the entire region. Conditions then dry out on Thursday as winds increase. Winds then diminish into Friday and the first half of the weekend, which will again lower fire weather concerns. && .PRELIMINARY POINT TEMPS/POPS...

No significant changes have been made to the forecast. Some interior rain showers very late tonight, but any snow showers confined to the very highest terrain. Relatively mild conditions today, and especially Wednesday, with sharply colder weather arriving later Thursday into Friday behind a strong cold front. While a significant storm appears unlikely Saturday night into Sunday, a bit of snow is certainly possible. && .KEY MESSAGES... - Overall quiet weather today, followed by a period of showers late tonight across interior southern New England with some snow showers confined to the very highest terrain. - Mild weather Wed into Wed night with a few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. Highs Wed in the 40s to near 50. - Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. - Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. && .DISCUSSION... KEY MESSAGE 1...Overall quiet weather today, followed by a period of showers late tonight across interior southern New England with some snow showers confined to the very highest terrain. A series of shortwaves quickly move from west to east tonight along zonal flow. First disturbance passes with little impacts outside of an increase in mid and high level clouds this morning across northern MA. Milder day follows as a transient ridge axis develops over New England. Latest guidance still shows a milder day on tap as 925mb temps climb to 0- 2C. A more amplified shortwave digs over the Great Lakes later Tuesday into Tuesday night. First sign of its approach will be increasing mid and high level clouds later today. Should see a broken band of precipitation pass through the CWA with the higher chances located across northern Massachusetts. Much of the forcing with this shortwave will be confined to Northern New England and so shower activity will be limited in coverage and intensity. May also see a few flakes mix in across the higher terrain but accumulations if any will be light with marginal temperatures and modest QPF. KEY MESSAGE 2...Mild weather Wed into Wed night with a few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. Highs Wed in the 40s to near 50. An amplifying shortwave trough moves across the Great Lakes and into northern New England Wed into early Thu. Out ahead of this cold front/amplifying shortwave trough, southerly flow will result in unseasonably mild temperatures. Despite considerable clouds, high temps will be well into the 40s to near 50 in a few spots. These readings are a solid 10+ degrees above normal for mid January standards. Given the bulk of the dynamics passing to our north, not expecting a lot of precipitation and much of this time will feature dry weather. Nonetheless, a few showers will be possible at times Wed into Wed night with the focus for them across interior southern New England closer to the shortwave energy. As colder air begins to work in from the west, may see precipitation end as a brief period of light snow showers across interior southern New England early Thu morning. Any snow accumulations should be a dusting to generally less than 1 inch. KEY MESSAGE 3...Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. Low pressure will rapidly intensifies Thu into Thu night as it tracks northeast from northern new England into the Canadian Maritimes. The result will be a shot of much colder air working into southern new England Thu into Fri. Temps on Thu will likely fall during the afternoon into the upper 20s and 30s on a stiff gusty west wind. Low temps Thu night will drop into the upper single digits and teens. Wind chills will drop to between 5 below and 10 above by daybreak Fri. High temps on Fri will only recover into the upper 20s and lower 30s. High pressure building in from the west will keep our weather dry, despite the cold conditions. KEY MESSAGE 4...Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. High pressure quickly moves east of the mid-Atlantic coast to start this weekend as another trough gets carved out across the Great Lakes. This allows for a quick rebound in temperatures with highs mainly in the 40s on Sat. The forecast then becomes quite complex Sat night into Sunday with an amplifying trough to our west with several pieces of shortwave energy. The problem is that the guidance is struggling on which piece of energy to amplify and where the actual surface low develops. Latest guidance tends to develop the main surface low too far north and late for a significant storm. That being said, there are a few pieces of guidance including the CMC/ICON that have a wave of low pressure further south with the potential for an inverted trough setup. So while a significant storm appears unlikely, given the amount of shortwave energy to our west we cannot rule out period of snow sometime Sat night into Sun if an inverted trough sets up. Whether or not this happens remains to be seen, but it is something to watch in the coming days. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High -greater than 60 percent. Through Tonight...High confidence. Mainly VFR. Very brief MVFR conditions possible across the interior between about 03-09Z in a few brief rain showers. Any snow showers will be confined to the very highest terrain of the Berkshires and northern Worcester Hills and rather short-lived too. Modest LLJ developing will result in periods of SW wind gusts of 20 to 25 knots tonight near and southeast of the I-95 corridor. LLWS included for some terminals given winds at 850 mb on the order of 45 to 55 knots. Wednesday...High Confidence. VFR for most. Areas MVFR and local IFR towards the Berkshires during the afternoon. Low risk for some rain showers as well. Wednesday Night...High Confidence. Mainly VFR to start across the eastern half of southern New England. Areas MVFR with local IFR across the western half expanding east after midnight. Widespread MVFR with IFR across the higher terrain expected towards the Thursday morning push.

Issued at 430 AM EST Tue Jan 13 2026 KBYX radar has remained active all night with the shower activity mostly across the Straits of Florida. However, occasionally a few showers have moved across the Upper Keys, especially near Key Largo. MRMS data over the last 3 hours show estimated rainfall amounts of a trace to a few hundredths of an inch of rainfall in association with these showers across the Upper Keys. The heaviest amounts remain across the central Straits where upwards of three tenths of inch were estimated due to heavier activity. GOES 19 Nighttime Microphysics shows partly cloudy skies across the Keys with the most robust cloud cover across the SE Gulf and the Straits of Florida. Temperatures along the Island Chain are in the lower 70s and dew points are in the upper 60s to near 70 degrees. An elongated surface ridge remains in place across the Southeast U.S. early this morning. This is promoting mainly northeast breezes of 10 to 15 knots at marine platforms surrounding the Island Chain. .FORECAST... The surface ridge currently across the Southeast U.S. will continue to drift southeastward through tonight while weakening. This will result in light to gentle breezes during the day becoming mainly light for tonight. High moisture for this time of the year remains in place across the Keys leading to chances PoPs for the next several forecast periods. The exception will be tonight when rain chances drop to slight due to a subtle dip in moisture. GOES 19 Total Precipitable Water (TPW) shows estimated PWATs of 1.3 to 1.5 inches across the Keys which is between the 75th and 90th percentile for the date. In addition, a pre-frontal trough will approach the Keys Wednesday/Wednesday night. Modest instability, plenty of moisture, and a trigger being the pre- frontal trough will yield the potential for a slight chance of a thunderstorm. The better risk for a thunderstorm will remain across the marine area where the greater instability, moisture, and lift will be. Latest statistical guidance has backed off on the idea of thunder across the area, however, confidence wasn`t high enough this update to remove it just yet. Most likely this will be scrutinized period by period. One of the other reasons for not removing just yet is that we will have some upper level forcing this go around which we typically don`t always see in the Keys. The main show arrives Thursday when a strong cold front will usher in Florida winter for the next several days and through the length of the extended. Temperatures and humidity are expected to tumble Thursday night. Overnight lows are expected to be 50 to 55 for Thursday night with daytime highs Friday only managing 60 to 65 degrees. The air conditioners will be able to get a well deserved break for late week through at least the middle of next week. Accompanying the frontal passage, expect a rapid surge in breezes across all the Florida Keys with breezy, becoming windy conditions anticipated along the Island Chain. For the marine area, the potential exists for a window of near gale breezes. The peak of the wind surge right now looks to be Thursday afternoon and evening before gradually slackening thereafter. Breezes will originally be westerly before shifting to the northwest to north overnight and then north by Friday morning. Breezes rapidly slacken by Friday afternoon as the gradient collapses. The cold front will push out any residual moisture resulting in a dry forecast from Thursday night through the extended. Another reinforcing front may press through the Keys sometime Sunday/Sunday night keeping the chill going. Daytime highs through the period will be near 70 degrees and overnight lows in the upper 50s to near 60 degrees. Dew points will also have a hard time reaching 60 degrees after the front passes through on Thursday. && .MARINE... Issued at 1111 AM EST Tue Jan 13 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, a surface ridge stretching across the southeastern U.S. will weaken and slide southeastward through tonight. This will promote slackening breezes to light to gentle. Thereafter, a pre- frontal trough will slide across the region on Wednesday, briefly clocking winds around to the southeast initially, then southwest, and eventually west to northwest. This will be followed by a second, stronger cold front on Thursday with a round of strong to potentially near gale breezes. Small Craft Advisories are becoming increasingly likely later this week. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None. GM...None. && $$ |

Issued at 320 AM EST Tue Jan 13 2026 - A couple degrees warmer today with isolated showers, mainly Cape Canaveral southward - Strong cold front arrives Wednesday night into Thursday morning, bringing a brief increase in rain chances - Below normal temperatures Thursday onward; sub-freezing morning lows and frigid wind chills in the 20s to 30s, especially Friday morning and next Monday morning && .DISCUSSION... Issued at 320 AM EST Tue Jan 13 2026 Today-Tonight...An inverted surface trough remains just offshore this morning while a low cloud deck persists over the northern half of the area. The most recent cold front to move through ECFL has settled across the Florida Straits as a stationary front. Current temperatures range widely from the low/mid 50s north of Orlando to the upper 60s along the Treasure Coast. Where moisture remains marginally sufficient today, mainly over the Treasure Coast and Gulf Stream, isolated showers will be possible. That said, a majority of the area will stay dry with temperatures warming a few degrees more compared to yesterday (highs in the low/mid 70s). Moisture return and the south Florida front moving north helps to expand 20-30% rain chances northward overnight, but the majority of activity will be focused out over the Gulf Stream. In other words, a continuation of isolated showers will simply expand north toward Cape Canaveral and even the Volusia Coast through daybreak Wednesday. Lows tonight are forecast to settle into the mid 50s north to the low/mid 60s from the Orlando metro to the Treasure Coast. Wednesday-Thursday...Wednesday morning, a weak cool front looks to be draped across portions of the Treasure Coast and Gulf Stream waters, before sliding east of the area by midday. Our focus is on the next series of cold fronts, approaching central Florida late Wednesday night into Thursday morning. 500mb height falls begin in earnest late Wednesday afternoon as a trough deepens over the eastern U.S. Rain chances look limited Wednesday, with one batch of QPF shifting well offshore and models in disagreement on very light QPF north of Orlando in the afternoon. We will be waiting on the arrival of a stronger cold front early Thursday, bringing with it slightly better rain chances (30-55%). Model guidance lends to a little lower confidence than is typical at this time range. GFS+AI ensembles point to generally 0.2" or less of measurable rain between now and the FROPA Thursday morning, whereas the ECMWF+AI ensembles are more centered around 0.3"-0.4" of rain. Granted, a couple tenths of rain is not a huge difference with most of the area under D0-D1 (abnormally dry to moderate drought) conditions. As quickly as rain moves in, it will move out over the open Atlantic Thursday afternoon. A westerly breeze Wednesday under a mostly cloudy sky is likely to keep temperatures a bit cooler, especially north of I-4. Behind Thursday`s front, noticeably colder and drier will rush southward supported by a 10-15+ mph wind (gusting 20-25 mph at times, especially at the coast). Highs in the upper 60s to mid 70s Wednesday trend down on Thursday, struggling to reach the 60-degree mark Orlando northward. Skies quickly clear Thursday night, setting the stage for a cold night and brisk wind chill values. Friday-Monday...Before stepping outside for work or school Friday morning, be sure to dress warmly! Forecast morning lows have not changed much from the previous cycle, maintaining the idea of temperatures at or below freezing along and north of I-4, in addition to sub-freezing lows across interior ECFL as far south as Lake Okeechobee. Making it feel even colder will be a northwest breeze, sending wind chill values into the mid/upper 20s for a majority of the area. As a result, a Cold Weather Advisory will be needed for a large portion of ECFL Friday morning. Winds decrease through the day Friday into early Saturday as high pressure builds over the peninsula. Despite plenty of sun Friday afternoon, temperatures will really struggle to get out of the 50s from Osceola/northern Brevard and points north (low 60s south). Mostly clear conditions Friday night sets the stage for another cold night (30s-mid 40s). With lighter winds overnight, there is a possibility of frost developing Saturday morning over portions of the area. Daytime temperatures make a comeback, climbing into the 60s to low 70s. But then... Below normal temperatures look to be reinforced by another cold front Saturday night into Sunday. A lack of moisture along this front is keeping rain chances out of the forecast. Temperatures swing colder again Sunday into early next week, with lows in the 30s to mid 40s and highs only in the 50s and 60s. Sub-freezing temps are possible again, especially Monday morning. Behind the front, northwest winds will again add a wind chill factor with values falling into the mid 20s to low 30s Monday morning. && .MARINE... Issued at 320 AM EST Tue Jan 13 2026 Weak surface trough remains over the nearshore waters through tonight as N-E winds decrease today. Isolated showers are forecast along the Treasure Coast and over the Gulf Stream, expanding north and eastward in time, especially on Wednesday. Seas fall to 3-4 ft today and 2-4 ft Wednesday. A strong cold front approaches early Thursday morning, quickly pushing south of the waters by the afternoon. Shower chances increase to 40-60%, followed by freshening NW winds behind the front. Poor to hazardous boating conditions gradually expand from the offshore waters Thursday morning to the remaining marine legs Thursday afternoon. NW winds 20-25 kt with gusts around 30 kt (esp. offshore) build seas to 4-7 ft nearshore and 6-9 ft offshore Thursday night. The pressure gradient quickly unwinds Friday as high pressure builds overhead, allowing seas to fall to 3-6 ft Friday afternoon. Favorable boating conditions return Friday night and continue through much of Saturday (seas 2-3 ft). && .AVIATION...

No significant changes to the forecast have been made. The main focus will be the arctic air moving in Thursday and beyond. && .KEY MESSAGES... 1) Rain Chances Return on Wednesday 2) A pair of strong arctic cold fronts moving through Thursday morning and again Saturday night will bring well below normal temperatures to the area. && .DISCUSSION... KEY MESSAGE 1... Rain Chances Return on Wednesday A lifting shortwave will move through the area on Wednesday in advance of a cold front on Thursday. Moisture above 700 mb is more than sufficient for precip, but dry air in the low levels will likely impact rain rates and QPF. Light rain will likely be focused along the coast where isentropic lift is maximized. Unlikely to see more than a few hundreths of rainfall through 12Z Thursday. Evaporative cooling should keep temperatures in the mid 50s. KEY MESSAGE 2... A pair of strong arctic cold fronts moving through Thursday morning and again Saturday night will bring well below normal temperatures to the area. No measurable precipitation is expected through the period. Cold arctic air will move in behind the first of basically two fronts Thursday and again this weekend. The coldest lows will occur Friday and again Sunday mornings when upper teens to lower 20s are expected. Apparent temperatures will be well into the teens. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... High confidence in VFR. LLWS is possible tonight as a weak southerly low level jet develops overhead. This is likely to remain below 20- 25 knots of shear, but could cause some trouble for smaller aircraft. Clouds increase late in the period ahead of an approaching shortwave, trending toward MVFR late Wednesday afternoon or Wednesday evening. Extended Forecast... Restrictions possible on Wednesday evening with light rain across portions of the area, best chance along the coast. VFR returns Thursday. && .MARINE... Through Wednesday... Winds turn southwesterly this afternoon and this evening, increasing overnight. West to southwest winds on Wednesday will precede a shortwave moving northeastward through the afternoon. With clouds increasing late tonight and early Wednesday, precipitation over the nearshore waters could begin as early as mid morning. Wednesday Night through Sunday...Strong small craft advisory conditions are expected Thursday and again this weekend via strong cold air advection behind a couple of arctic cold fronts.

Updated at 1149 AM CST Tue Jan 13 2026 - There is a low (15-30%) chance of intermittent light rain or drizzle late this afternoon into the early nighttime hours tonight. - A cold front is expected to pass through the region Wednesday evening into Wednesday night. - A Small Craft Advisory is likely for the Lower Texas coastal waters Wednesday night into Thursday as strong northerly winds behind the front leads to adverse marine conditions. && .DISCUSSION... Issued at 1149 AM CST Tue Jan 13 2026 A mid-level trough moves eastward over central Texas today, passing north of our region, with slight upper level divergence and a weak jet aloft continuing into tonight, generating a low (15-30%) chance of rain from a line of isolated to scattered light showers or drizzle, moving east from the Northern Ranchlands and Mid/Upper RGV this afternoon and exiting the Lower RGV tonight. Ahead of the line, light northerly winds shift to southwesterly as the line exits, becoming light westerly by Wednesday morning and northerly by the evening hours, influenced by lower level winds shifting ahead of a ridge and cold front diving into the Southern Plains. The cold front passes through Deep South Texas and the Rio Grande Valley Wednesday evening into Wednesday night, leading to breezy conditions near and along the immediate Lower Texas Gulf coast, with northerly winds of around 20-25 mph and gusts up to 30 mph. Thursday into Friday, winds subside and become southerly by Friday as a surface high pressure shifts east from the Southern Plains to the northeastern Gulf. Another ridge flies southeastward over the Plains on Friday, sending another cold front, possibly late Friday night into Saturday, shifting winds out of the northeast through Saturday and gradually becoming southeasterly by Monday. As moisture rebuilds into the region next week, there could be an increase in PoPs to a low (15-30%) chance of rain along the coast Monday, expanding inland into Tuesday. Near to slightly below average temperatures today (highs in the 60s) and tonight (lows in the 40s/50s) become above average on Wednesday as skies begin to clear and downsloping westerly winds raise highs into mostly the 70s to near 80 F. Temperatures falling back to the 40s/50s overnight Wednesday as skies become mainly clear behind the front, allowing for efficient radiational cooling. Cold air advection via northerly to northeasterly winds cool temperatures back to the 60s on Thursday before 70s return on Friday with morning lows in the 40s/50s continuing into the weekend. A moderate risk of rip currents continues through Wednesday afternoon. && .AVIATION... (18Z TAFS) Issued at 1149 AM CST Tue Jan 13 2026 There is a low (15-30%) chance of intermittent light rain or drizzle at KMFE and KHRL this evening into the early nighttime hours as well as at KBRO late this evening into tonight, mentioned in the PROB30s, which could result in periods of MVFR ceilings and/or visibility. Following, there could be a brief period of LIFR/IFR ceilings around sunrise Wednesday morning due to elevated moisture. VFR conditions return soon after, with light westerly winds becoming northwesterly by the afternoon hours with clearing skies. && .MARINE... Issued at 1149 AM CST Tue Jan 13 2026 Gentle northerly winds become light westerly winds by Wednesday morning along with slight (1-2 feet) seas along with a low (15-20%) chance of patchy light rain or drizzle. Winds turn northwesterly, enhancing to moderate to fresh late Wednesday morning into the afternoon. A Small Craft Advisory is likely Wednesday night into Thursday as a cold front passes through the Lower Texas coastal waters, bringing strong northerly winds and moderate (6-8 feet) seas, followed by improving conditions Thursday afternoon into Thursday night. Winds become southerly along with slight (1-2 feet), possibly by Friday morning, with gentle to moderate southeasterly winds continuing through the weekend with a potential weak cold front Friday night or Saturday as well as building chances of rain next Monday. && .PRELIMINARY POINT TEMPS/POPS...

Model trends continue to favor a more progressive (faster) and drier solution for the late week system. This translates to a lower chance for accumulating winter precipitation Thursday morning. && .KEY MESSAGES... 1) Remaining dry, while trending breezy and milder today through Wednesday. 2) Low pressure develops along an approaching cold front Wednesday night, and passes by to the N/NE of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of snow showers Thursday morning. Little to no snow accumulation is expected. 3) Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. && .DISCUSSION... As of 625 AM EST Tuesday... KEY MESSAGE 1...Remaining dry and trending breezy and milder today and Wednesday. Strong sfc high pressure (~1030mb) is centered over the Gulf coast, ridging ENE into the local area will build south across the southeast today, as low pressure over central Canada remains well north of the local area. SSW return flow becomes a bit stronger today, allowing for highs to warm up quickly into the 50s under a mainly sunny sky. A few readings around 60 degrees are possible across south central VA and NE NC. A few clouds cross the area tonight and early Wednesday ahead of the cold front associated with the northern stream system, but otherwise mainly clear and not as cold tonight with lows in the 30s. Despite some increasing mid to high clouds Wednesday, mild return flow will provide highs well into the 50s west of the bay again on Wednesday (low to mid 50s Lower Eastern Shore), with highs near 60 degrees far SE counties. KEY MESSAGE 2...Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of light snow Thursday morning. 00z/13 models continue to advance a faster, drier solution for the late week system. A potent northern stream shortwave will dig south from the Ohio Valley into the northern mid- Atlantic late Wednesday through Thursday, as a dampening southern stream shortwave traverses the Gulf coast. Our area will be in between these features, with the resultant subsidence allowing for rapid drying and therefore lower QPF. There is still a chance for some light overrunning moisture to cross the area, along and (mainly) behind the crossing cold front Wed night. Precipitation will mainly fall in the form of light rain showers. While the faster arrival of colder air would allow for a changeover to snow showers as precipitation tapers off early Thursday morning, it is increasingly apparent that the colder air will be chasing the departing moisture, with the developing surface low crossing near of just south of the Mason-Dixon line as it exits to the NNE. This is a pattern that rarely results in any tangible snowfall across most of our region. For its part, the latest NBM remains a bit higher than latest model consensus, likely still at least in part reflecting the previous model consensus of this past weekend. Would therefore not be surprised to see these chances drop off completely as we get closer. Thus, while some light snow is possible before precipitation tapers off, have removed any snow accumulations from the digital database and expect very limited to no impacts from snow with this system. KEY MESSAGE 3...Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. Becoming rather cold and breezy/windy in strong cold advection in the wake of the Arctic frontal passage Thursday. Look for highs to struggle to get out of the 30s N and in the 40s S, even w/ diminishing cloud cover. Cold w/ lows in the teens and 20s Thu night. Even as winds diminish, wind chills in the teens are expected Friday morning. Not quite cold enough for Cold Weather Advisories but close, and certainly a stark contrast from the warmer temperatures expected today and tomorrow. The rest of the extended period will primarily feature below normal temperatures and mainly dry conditions. An upper level ridge persists across the west coast of North America, keeping an upper level trough in place from central Canada into the SE CONUS, with resultant NW flow allowing for another influx of Arctic air in the wake of a second, reinforcing Arctic frontal passage over the weekend. Guidance is still keying in on a pair of weak disturbances, one ahead of and one just behind that next strong cold frontal passage. At this point, the "best" chance for any precipitation looks to be on Sunday, though PoPs remain low at only 15-20%. The overall pattern still appears too progressive to tap into any southern stream moisture, reinforcing the developing cold, dry pattern. Another round of cold temperatures follows behind that front for Sunday night through early next week, with highs in the 30s and lows in the teens to low 20s. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 1250 PM EST Tuesday... VFR conditions prevail across all terminals through the 18z/13 TAF period. Clear skies across the area currently, with FEW-SCT high clouds moving into the northern portions later this afternoon. W/SW winds around 10 kt will continue through the period, with RIC seeing some gusts to 15-20 kt this afternoon. SBY may see some gusts to 15- 20 kt after 00z/14. Additionally, some low-level wind shear is likely this evening into Wednesday afternoon, especially at RIC, ahead of the next passing cold front. SCT-BKN high clouds will return across the entire area Wednesday morning with the cloud shield from the next approaching low pressure system to the north and associated cold front. Outlook: The cold front will cross the local area Wednesday evening through early Thursday with some light rain showers possible. A brief period of sub-VFR conditions will be possible early Thu morning, as a secondary front crosses the region, ushering in a much colder airmass for the late week period into the weekend. && .MARINE... As of 220 AM EST Tuesday... Key Messages: - SCA conditions expected tonight due to gusty SW winds. - A series of cold fronts will cross the region late this week with strong SCA conditions possible Thursday into Friday. High pressure is situated south of the waters this morning. SW winds are generally 10-15 kt with occasional gusts to 20 kt, but these winds will subside later this morning into this afternoon. The aforementioned high translates offshore by this evening as strong low pressure advances through SE Canada, tightening the pressure gradient over the area. In addition, a SW low-level jet still looks to overspread the waters tonight into Wednesday morning. Southerly flow picks up again this afternoon but should remain sub-SCA until ~00z/7 PM this evening. After 00z, winds become SW and increase to 15-20 kt on the Chesapeake Bay with some potential for 20-25 kt sustained winds on the coastal waters N of Parramore Island. Gusts up to 25-30 kt are also expected. Small Craft Advisories have been issued for the Chesapeake Bay and coastal waters N of Cape Charles through mid-morning Wednesday. Sub-SCA SW flow should then prevail later Wednesday into the first part of Wednesday night. A strong cold front is then expected to swing through the region early Thursday morning as low pressure develops over New England. This front will bring an abrupt wind shift to the NW, along with a substantial increase in the wind speeds to 20-25 kt for most of the waters. These elevated winds likely persist into Thursday night as cold air advection maximizes. An additional round of Small Craft Advisories are very likely during this period. While forecasted gusts currently fall just shy of Gale-force, cannot rule this out on the ocean and will continue to monitor over the next few forecast cycles. Winds quickly subside around sunrise Friday morning before elevated SW flow potentially returns Friday night/Saturday morning ahead of another cold front. The current model consensus pushes this front through overnight Saturday and additional SCA headlines are probable as winds become NW. Seas are 2-3.5 ft this morning, with 1-2 ft waves in the bay. Seas and waves increase to 3-5 ft and 2-3 ft, respectively, tonight through Wednesday morning. Elevated seas and waves return early Thursday morning and continue into Thursday night in the wake of the cold front. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.

For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Several Freeze Events through Early Next Week. Friday Morning: Hard Freeze Inland & Coastal Light Freeze Likely - Dangerously Cold Wind Chills in the teens to low 20s Possible. Consecutive Nights of Inland Freezes Fri Night through Next Tue Night - Small Craft Advisory & Gale Force Gusts Thu & Thu Night && .NEAR TERM /THROUGH TONIGHT/... This afternoon...Partly sunny skies with temps closer to seasonable values for mid January in the lower 60s SE GA and mid/upper 60s for NE FL and around 60F for Atlantic Coastal Areas. North winds much lighter than yesterday around 10 mph or so. Tonight...Increasing cloudiness from the south and west overnight as a broad surface forms offshore of the FL Atlantic coast as a longer wave mid/upper level trough deepens across the western Gulf. Min temps not as cool with lows in the mid/upper 30 across inland SE GA and 40s to lower 50s elsewhere and will likely bottom out around midnight to 3am then hold steady or even nudge upwards towards morning as clouds continue to increase, which should also prevent any significant fog formation. A few light showers and sprinkles will also be possible overnight mainly across northeast Florida as the surface low that develops near the southeast FL Atlantic coast tracks northward, east of the local area, into early Wednesday morning. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... An upper level shortwave will quickly traverse across the region on Wednesday afternoon and evening, just a piece of energy associated with a deepening longwave trough over the south/central US. Despite the mid and upper level forcing, rain chances with this feature will be quite limited given the ongoing drought as well as limited layer moisture. However, a few light showers/sprinkles will likely traverse from west to east during the afternoon and evening, with rain chances around the 15 to 20 % range. With plenty of cloud cover and this feature acting as a weak pseudo cold front, high temps will be a bit cooler on average area wide: ranging from the mid to upper 50s over interior southeast GA to the low to mid 60s elsewhere. Main portion of the deepening/southeastward digging upper trough moves towards the area Wednesday Night and across the region through Thursday, with an accompanying strong cold front traversing eastward out ahead of the feature. Timing of the frontal passage is generally as follows: entering southeast GA around late Wednesday Evening, towards the I-10 corridor by about early morning Thursday, then clearing the entire region by about mid to late morning Thursday. Along with strengthening/gusty northwesterly winds behind the front during the daytime, a few showers will be once again possible overnight Wednesday and through the first half of Thursday, mainly across northeast FL where just a bit more moisture advection will be expected off the Gulf. Though overall, similar to Wednesday, moisture is quite limited despite the rather impressive forcing aloft, and combined with the mostly non-diurnal timing of the boundary, rain chances will therefore be limited to about the 30-50% chance at most for northeast FL and very low across southeast GA as much drier air starts to advect into the early throughout the morning hours. As expected, Thursday will be a much cooler day with the front moving through during the first half of the day, with upper 40s to low 50s north and west and mid to upper 50s south and east. Thursday Night will feature clouds continuing to exit the area with a cold night in store. Thursday Night will be tricky with respect to both ambient min temperatures as well as apparent temps/wind chills, as it will highly depend on how quickly gusty northwesterly breezes subside as surface high pressure will start to center closer to right over the area by sunrise Friday Morning. Overall, both frost/freeze and Cold Weather Advisory products will be in play to Thursday Night and Friday Morning, which will continue to be evaluated through tomorrow. Though generally speaking, a hard freeze is likely inland with highs in the 20s, and in the upper 20s to low 30s closer to the coast and St. Johns Basin which very much keeps frost/freeze potential in the discussion all the coast. && .LONG TERM /FRIDAY THROUGH MONDAY/... Cool high pressure will remain across the region on Friday before scooting off to our east Saturday as another frontal system approaches the region. This next cold front looks to move through the region Saturday Night into Sunday Morning, which once again looks like a mostly dry frontal passage. Dry high pressure is then expected to remain in place Sunday afternoon through the start of next week, remaining west or northwest of the region which will keep a cool continental drainage type flow in place. Aside from a bit of a "warmup" Saturday as the next frontal approaches and moves through, temps below normal will be expected for most of the long term. This will include chances for frost/freeze products each morning inland, and perhaps even closer to the coast Monday Morning. && .AVIATION /18Z TUESDAY THROUGH 18Z WEDNESDAY/... Mainly VFR conds through the afternoon with SCT-BKN clouds around 5000 feet or so along with North winds in the 5-10 knot range. These conditions will continue this evening, with increasing clouds in the mid levels through the overnight hours, along with low probs of MVFR CIGS towards sunrise at NE FL TAF sites and will trend in this direction in the next TAF package. Low rainfall chances at NE FL TAF sites in the 20-30% range by the 12-18Z time frame, but will likely leave out of the TAF forecast for now. && .MARINE... A coastal trough over the waters breaks down this afternoon and shifts farther offshore as high pressure builds across the the Gulf coast states. The high will extend across the local waters tonight into Wednesday as a broad surface low tracks northward well east of the local Atlantic coast. Westerly winds increase Wednesday night as a strong cold front moves across the region. Small craft advisory conditions return Thursday trailing the frontal passage and continue into Thursday night. Winds and seas subside Friday as high pressure builds directly over the local waters. The high will shift southeast Saturday as a weaker, dry cold front moves across the waters with a surge in northwest to north winds behind the frontal passage late Saturday into Sunday. Rip Currents: SE GA Low Wednesday NE FL Low Wednesday && .FIRE WEATHER... -Areas of low dispersions Today -Areas of high dispersions Thursday High pressure over the southeast US will sink southward into the Gulf today, keeping winds generally out of the north to northwest. Winds will be strongest near the coast and St. Johns River Basin thanks to a coastal trough that will weaken throughout the day. Winds above the surface and therefore transport winds will be weak today, resulting in mainly low/poor daytime dispersions today. Lingering dry airmass will create MinRH values of 22-27 percent over inland Georgia northwest of about US84. Wednesday, west-southwest winds increase ahead of an approaching front resulting in good dispersions. Light scattered showers will be possible as a weak front moves through the area Wednesday into Wednesday night, though Thunder is not expected. Breezy northwesterly winds develop in the wake of the front bringing high dispersions area-wide on Thursday. A cold and dry airmass filters in for the end of the work week lowering RHs into the 20s. Elevated Fire Danger will be possible for inland southeast Georgia on Thursday due to breezy winds and low RHs. FOG POTENTIAL AND OTHER REMARKS: Significant fog is not expected over the next several days. A widespread freeze is forecast for Thursday night, including areas of frost as well.

Issued at 1115 AM CST Tue Jan 13 2026 - Cold temperatures are expected over the next 7 days. Sub- freezing temperatures are forecast across much of the area, especially Thursday night and over the weekend. - Strong northerly winds will occur over the marine area Wednesday night and Thursday, creating hazardous conditions for small craft. && .DISCUSSION... Issued at 1145 PM CST Mon Jan 12 2026 Another cool and dry day is expected for today as high pressure lingers across the area. This high will push southward into the Gulf and weaken as our next reinforcing cold front sweeps through the area Wednesday night. Looking aloft, a southern stream shortwave trough, located over western Texas will quickly approach the local area by tonight. Winds aloft will briefly turn southwesterly as it approaches. Although moisture return is still quite limited (PWATs remain below an inch), there may be enough forcing to squeeze out a few isolated to widely scattered showers as the trough passes overhead during the overnight hours. With the cold airmass still in place, expect a very light, overrunning rain. By the afternoon, longwave troughing diving southward from Canada will phase with the southern stream shortwave and push to our east by Wednesday night. This trough will help to send the aforementioned cold front through our area. Once again, a few light rain showers cannot be ruled out as the front pushes through. Behind it, another cold, dry airmass filters in from the north as high pressure builds in. Highs for today and Wednesday will be in the upper 50s to low 60s. Lows tonight will dip into the upper 30s to low 40s. After the front passes through Wednesday night, temperatures on Thursday will crash into the mid to upper 40s for highs and the low to mid 20s for lows Although winds Thursday night look to be rather light, apparent temperatures may get close to our Cold Weather Advisory criteria. We`ll keep an eye on this potential over the coming days. The second half of the period will be strikingly similar to the first half. By Friday and Saturday, highs will rebound to the upper 50s to low 60s, with lows Friday night ranging from the mid 30s inland to the low 40s along the coast. Another longwave trough is set to dig southward from Canada, helping to send yet another reinforcing cold front through our local area Saturday into Saturday night. Limited moisture return should keep PoPs low, although would not be surprised to see a few isolated showers pop up. After the front passes through temperatures drop once again, with highs Sunday and Monday in the upper 40s to low 50s and lows dropping into the 20s. A Low Risk of rip currents remains in place through much of the period, with a brief bump to Moderate expected Wednesday night for our western Florida Panhandle beaches. /96 && .AVIATION...

Updated at 1210 PM EST Tue Jan 13 2026 - Occasional showers continue today favoring east coast metro areas. - Hazardous winds and seas in the Atlantic will improve today. - Another strong cold front could drop across the peninsula on Thursday, bringing reinforcing cold air and more increased rain chances. && .UPDATE... Issued at 1210 PM EST Tue Jan 13 2026 Overcast skies and light shower activity continues through this afternoon and potentially the evening as well due to a lingering frontal boundary to the south over the Florida Straits. This is leading to cloudy skies and stratiform rain over SE Florida. Rainfall rates are very light, so no major hazards will occur. High temperatures will struggle to rise given the ample cloud cover and light rain, likely only reaching the low to mid 70s for most areas, but especially for the east coast metro. && .SHORT TERM... (Today through Wednesday) Issued at 300 AM EST Tue Jan 13 2026 Latest ensembles and global model solutions show a decaying sfc boundary lingering over SoFlo today, and maybe lifting a little northward. This will require keeping some POPs through early this evening, 20-30 percent, favoring the eastern side of SoFlo. 00Z MFL sounding and model data keep PWATs in the 1.3-1.5" range, for which potential for isolated rainfall amounts of 1" still remains in the forecast. By Wednesday, models show a mid lvl shortwave feature moving around the base of a deepening trough over the SE CONUS. Both systems are shown migrating eastward, with overall synoptic flow veering more southwestward/westward by the afternoon hours. This will further focus highest chances of rain over the Atlantic coastline and around the Broward/Palm Beach metro areas. Meanwhile, a more robust sfc cold front will be pushed southward towards northern Florida by late Wednesday. High temperatures for the short term should remain in the upper 70s to near 80, with overnight lows tonight mainly in the low 60s, with some mid 60s around the east coast metro areas. && .LONG TERM... (Wednesday night through Monday) Issued at 300 AM EST Tue Jan 13 2026 Model consensus depict a FROPA reaching the area on Thursday, with rain chances increasing in the Wed night-Thu morning time frame ahead of the front. Latest timing with this feature places the best chances of showers during the mid/late morning hours on Thursday with scattered to numerous showers possible. In general, dynamic support seem to remain poor as the parent trough/low complex will continue to pull NE into the eastern seaboard. And with prevailing cloud cover, the daytime heating component should remain weak enough to keep mention of thunderstorms out of the forecast attm. This, however, will continue to be revised and updated as necessary. 50-70 POPs remain in the forecast for Thursday morning. Winds veer northward Thursday night into Friday as broad high pressure spreads across the SE CONUS, triggering another cold/dry air advection event. Coldest temperatures with this robust cold air mass are expected Friday morning before sunrise, with coastal areas dropping into the upper 30s to mid 40s, and interior/northern areas in the low-mid 30s. Friday afternoon will also remain fairly cool for being SoFlo, with highs struggling to hit the mid-upper 60s. Temperatures then gradually warm up during the weekend, but still remaining around the low 70s in general. Then by Monday, models seem to suggest another possible cool down with a front approaching the area. There is still a lot of uncertainty in long range guidance, so the forecast philosophy beyond the weekend will continue to be updated with new guidance. && .AVIATION... (18Z TAFS) Issued at 1210 PM EST Tue Jan 13 2026 MVFR/IFR CIGs continue for the east coast terminals this afternoon with no signs of clearing until tonight. Winds will be out of the east or east-northeast around 10 kts through this evening before becoming variable overnight. Light SHRA remains likely for several more hours at least for KMIA, KTMB, and KOPF. && .MARINE... Issued at 300 AM EST Tue Jan 13 2026 Hazardous boating conditions will continue until later this morning, then conditions will quickly subside and remain below highlight criteria through the middle of the week. A frontal passage is expected to bring another round of hazardous-level winds and seas for the Thursday night-Friday timeframe. && .BEACHES...

| #1257068 (Received by flhurricane at: 11:21 AM 13.Jan.2026) AFDKEY Area Forecast Discussion National Weather Service Key West FL 1113 AM EST Tue Jan 13 2026 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... -A few showers may brush the island chain over the next few days. There is the potential for slight chance of thunder through Thursday, though, the better risk is across the marine area. -A strong cold front will move through the Keys on Thursday. This will bring a period of breezy to windy conditions to the Keys along with strong to potentially near gale breezes to the Florida Keys coastal waters. Small Craft Advisories are becoming increasingly likely later this week. -In the wake of the front, expect considerably cooler and drier conditions for late week through the weekend. && .DISCUSSION... Issued at 1111 AM EST Tue Jan 13 2026 KBYX has had a busy morning with scattered showers throughout the Straits of Florida. These showers have started to move closer to the island chain, with even a few lightning strikes being detected about 10 to 15 miles to the south. Though most of these showers are surrounding the Middle Keys, they have not amounted to much rainfall. Temperatures across land are in the mid 70s and similar to yesterday, mostly cloudy skies will keep the temperatures near that for the day. Winds along the Reef are near 10 knots outside of convection currently. For the rest of the day, showers will continue to drift throughout the coastal waters with a majority of those being light and brief, but a few lightning strikes cannot be fully ruled out. The Coastal Water Forecast was updated to include isolated thunderstorms in the Straits of Florida for this afternoon and tonight, elsewhere, no changes were made to the update package. && .PREVIOUS DISCUSSION... Issued at 430 AM EST Tue Jan 13 2026 KBYX radar has remained active all night with the shower activity mostly across the Straits of Florida. However, occasionally a few showers have moved across the Upper Keys, especially near Key Largo. MRMS data over the last 3 hours show estimated rainfall amounts of a trace to a few hundredths of an inch of rainfall in association with these showers across the Upper Keys. The heaviest amounts remain across the central Straits where upwards of three tenths of inch were estimated due to heavier activity. GOES 19 Nighttime Microphysics shows partly cloudy skies across the Keys with the most robust cloud cover across the SE Gulf and the Straits of Florida. Temperatures along the Island Chain are in the lower 70s and dew points are in the upper 60s to near 70 degrees. An elongated surface ridge remains in place across the Southeast U.S. early this morning. This is promoting mainly northeast breezes of 10 to 15 knots at marine platforms surrounding the Island Chain. .FORECAST... The surface ridge currently across the Southeast U.S. will continue to drift southeastward through tonight while weakening. This will result in light to gentle breezes during the day becoming mainly light for tonight. High moisture for this time of the year remains in place across the Keys leading to chances PoPs for the next several forecast periods. The exception will be tonight when rain chances drop to slight due to a subtle dip in moisture. GOES 19 Total Precipitable Water (TPW) shows estimated PWATs of 1.3 to 1.5 inches across the Keys which is between the 75th and 90th percentile for the date. In addition, a pre-frontal trough will approach the Keys Wednesday/Wednesday night. Modest instability, plenty of moisture, and a trigger being the pre- frontal trough will yield the potential for a slight chance of a thunderstorm. The better risk for a thunderstorm will remain across the marine area where the greater instability, moisture, and lift will be. Latest statistical guidance has backed off on the idea of thunder across the area, however, confidence wasn`t high enough this update to remove it just yet. Most likely this will be scrutinized period by period. One of the other reasons for not removing just yet is that we will have some upper level forcing this go around which we typically don`t always see in the Keys. The main show arrives Thursday when a strong cold front will usher in Florida winter for the next several days and through the length of the extended. Temperatures and humidity are expected to tumble Thursday night. Overnight lows are expected to be 50 to 55 for Thursday night with daytime highs Friday only managing 60 to 65 degrees. The air conditioners will be able to get a well deserved break for late week through at least the middle of next week. Accompanying the frontal passage, expect a rapid surge in breezes across all the Florida Keys with breezy, becoming windy conditions anticipated along the Island Chain. For the marine area, the potential exists for a window of near gale breezes. The peak of the wind surge right now looks to be Thursday afternoon and evening before gradually slackening thereafter. Breezes will originally be westerly before shifting to the northwest to north overnight and then north by Friday morning. Breezes rapidly slacken by Friday afternoon as the gradient collapses. The cold front will push out any residual moisture resulting in a dry forecast from Thursday night through the extended. Another reinforcing front may press through the Keys sometime Sunday/Sunday night keeping the chill going. Daytime highs through the period will be near 70 degrees and overnight lows in the upper 50s to near 60 degrees. Dew points will also have a hard time reaching 60 degrees after the front passes through on Thursday. && .MARINE... Issued at 1111 AM EST Tue Jan 13 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, a surface ridge stretching across the southeastern U.S. will weaken and slide southeastward through tonight. This will promote slackening breezes to light to gentle. Thereafter, a pre- frontal trough will slide across the region on Wednesday, briefly clocking winds around to the southeast initially, then southwest, and eventually west to northwest. This will be followed by a second, stronger cold front on Thursday with a round of strong to potentially near gale breezes. Small Craft Advisories are becoming increasingly likely later this week. && .AVIATION... (15Z TAFS) Issued at 1111 AM EST Tue Jan 13 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Scattered showers are currently just south of MTH, therefore, VCSH included at that terminal. Direct impacts of showers could briefly lower conditions to MVFR and TEMPOs will be included if that is expected. Near surface winds are northeasterly at 5 to 10 knots. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None. GM...None. && $$ |

In the near term, no major changes coming down the track as we approach 7 AM EST. Updated 12Z TAF discussion below. All other previous discussions still apply. Forecast lows Thursday night have been adjusted colder, but wind chills are little changed. && .KEY MESSAGES... 1) Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. 2) Light rain is possible Wednesday as an upper level system moves overhead. 3) A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. && .DISCUSSION... KEY MESSAGE 1...Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. Some good radiational cooling has occurred just past midnight, as temperatures continue to dip towards the 20s. Some cirrus that is streaming in from the west has thickened up over the last hour or so, which I believe has already started to hinder the cooling. May need to back off on some of the hourly temperature forecasts as we head through the rest of this morning. Elsewhere, quiet forecast still in store through tonight. A shortwave moves through late this morning, but doesn`t really do much at all to change the sensible weather. Plenty of sunshine on the way, with highs creeping up into the upper 50s to near 60. This will solidly be 10-12 degrees warmer than yesterday, about a degree or two above normal for mid-January. Southwesterly flow starts building in tonight ahead of the next disturbance. This causes low temperatures to be considerably warmer than the last couple of nights, generally in the mid-to-upper 30s inland, lower 40s at the coast.here. KEY MESSAGE 2...Light rain is possible Wednesday as an upper level system moves overhead. A southern stream shortwave will be pulled northeastward and across the Carolinas on Wednesday by a deep upper level trough developing across the Great Lakes. This shortwave will carry a slug of mid level moisture with it, visible on model 700 mb progs between 15z Wednesday and 00z Thursday. Isentropic analysis within the moisture-bearing layer shows only modest upglide, but still likely enough to produce light rain with less than 0.10 inches expected. Forecast PoPs have been tweaked higher to 40-50 percent along the coast centered on Wednesday afternoon. Very dry air between the mid level cloud base and the surface means there could be evaporational cooling as precipitation begins. I`ve kept Wednesday`s forecast highs near the NBM for now, but there`s certainly potential that highs will come in lower than is currently forecast if precipitation is more widespread or heavier in intensity. KEY MESSAGE 3...A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. Strong cold advection behind Thursday`s early morning arctic cold front will continue through the day and into Thursday night. Although yesterday morning`s models showed a decrease in wind speed late Thursday night, the new 00z models arriving now show this decrease in wind even more acutely. This should allow a radiational inversion to develop, especially inland, and we`ve accordingly pushed forecast lows down another couple of degrees. We`re now expecting lows in the upper teens with some lower 20s near the coast. This looks to be the second coldest arctic outbreak of the winter (so far) behind the December 15, 2025 event. In terms of public impact, lower forecast temperatures are being offset by lighter forecast winds. Forecast wind chill temperatures are still near the 15 degree threshold needed for a Cold Weather Advisory late Thursday night/Friday morning. Although model spread widens by the weekend, a second arctic cold front appears likely to arrive across the eastern Carolinas either Saturday night or Sunday morning. This will be followed by another shot of well below normal temperatures early next week. && .AVIATION /14Z TUESDAY THROUGH SATURDAY/... High confidence in VFR through the 12Z TAF period. Calm winds in place at all terminals, which will continue for the next several hours. Light breeze at 5-7 kts out of the SSW builds in by 17-19Z this afternoon, decreasing slightly to 4-6 kts by sunset. Extended Outlook...VFR through perhaps midday Wednesday. Some restrictions are possible late Wednesday and Thursday. VFR returns Thursday night through Saturday. && .MARINE... Through Tonight...NNW winds around 5 kts back to the southwest by late this afternoon, increasing towards 10 kts by sunset. Winds veer slightly to the WSW overnight tonight, increasing more to 10-15 kts. Seas remain at 1-2 ft. Wednesday through Saturday Night...Breezy southwest winds as strong as 20-25 knots Wednesday night will precede a strong arctic cold front that will push off the North and South Carolina coastline early Thursday morning. Northwest winds behind the front on Thursday into Thursday night should average 20 to perhaps 25 knots. There is a good chance a Small Craft Advisory will be needed for the winds both ahead of and behind the cold front. High pressure building eastward along the Gulf Coast should lead to diminishing wind speeds Friday, however the high should push offshore Friday afternoon or evening with winds shifting southwesterly and increasing to 15-20 knots. Winds could increase further on Saturday when a second period of Small Craft Advisory conditions could occur ahead of the next front approaching from the west. && .ILM WATCHES/WARNINGS/ADVISORIES...

Issued at 828 AM EST Tue Jan 13 2026 Only minor tweaks were made to the temperature and dew point trends this morning to acount for some slightly colder temperatures. Otherwise, the forecast is on track. && .SHORT TERM... (Today and Tonight) Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis across the area today will lead to mostly clear to partly cloudy skies with just some passing high cloud cover. Afternoon highs will generally range from the upper 50s to mid 60s with overnight lows ranging from the mid 30s to mid 40s. && .LONG TERM... (Wednesday through Monday) Issued at 228 AM EST Tue Jan 13 2026 Two reinforcing cold frontal passages are expected. The first one will arrive starting late Wednesday, and the second one will arrive on Saturday or Saturday night. There will probably be some scattered light showers in advance of the front on Wednesday, but moisture will be limited with both fronts. Any rain that occurs will be on the light side. Breezy conditions are likely on Thursday behind the first front with peak gusts in the 25-35 mph range. The main impact to the local area will be cold temperatures. There is a medium to high chance of a hard freeze (25F or lower) for inland areas on Friday morning. Additional light freezes are expected for portions of the area each morning thereafter into early next week. Despite all the cold temperatures, there is currently no wintry precip expected in our area. && .AVIATION... (12Z TAFS) Issued at 615 AM EST Tue Jan 13 2026 Smoke from a nearby prescribed burn has lead to restrictions less than a mile in haze at TLH early this morning. As of this time, haze has subsided, but cannot rule out a brief return. Surface high pressure ridge axis gradually moves south of the terminals today. Light and variable winds become north today with a tendency to become more westerly at DHN and ECP during the afternoon. With the weak pressure gradient in place, winds generally AOB 5 kts. VFR w/SCT cirrus becoming BKN late today. && .MARINE... Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis will move south directly across the waters by this evening, bringing a continued decrease in wind. Once high pressure moves further south on Wednesday, westerly breezes will freshen in advance of a strong reinforcing cold frontal passage on Wednesday night. Northwesterly gusts near gale force will follow that front on Thursday with the strongest winds west of Apalachicola. Winds will quickly decrease on Thursday night and Friday as a high center passes directly across the waters Friday evening. Yet another cold front will cross the waters on Saturday evening. && .FIRE WEATHER... Issued at 228 AM EST Tue Jan 13 2026 The high pressure center at the heart of the existing dry air mass will pass directly across the districts today. This will result in a combination of places with critically low humidity below 25 percent and low daytime dispersion due to the lack of wind and low mixing heights. On Wednesday, dispersion will increase markedly with higher values resulting from development of gusty southwest winds in advance of a strong reinforcing cold frontal passage late Wednesday. Strong gusty northerly winds will follow that front on Thursday, supporting another day of high dispersion. && .HYDROLOGY...

Issued at 709 AM EST Tue Jan 13 2026 The day is off to a cool and cloudy start. The 12Z sounding shows a layer of moisture below 800mb (approx. 6.5kft) with a strong dry layer above from 800mb to 700mb before moisture returns. The expectation is that this trapped moisture will largely remain in place today, suggesting mostly cloudy skies will continue. This is in response to the weak surface trough over the state. As such, the current forecast looks on track, with no changes needed at this time. && .AVIATION... (12Z TAFS) Issued at 709 AM EST Tue Jan 13 2026 MVFR to IFR CIGs are the main aviation concern until the next front moves through on Thursday. The window where CIGs are favored to be lowest will generally run from 06Z to approximately 14Z. However, these low CIGs still have the potential to occur at anytime. When the front moves through on Thursday, the window for low CIGs will extend until after the front passes. Additionally, some convection as well as gusty winds will be possible. && .DISCUSSION... Issued at 233 AM EST Tue Jan 13 2026 The front that pushed through on Sunday is still lingering just south of Florida. This front will lift slightly north today allowing for some extra cloud cover over the area. A shower or two will also be possible in SW Florida. By Wednesday we will see a much stronger cold front heading our way. This front will push through Wednesday Night bringing scattered showers as it passes by. Colder air will start to filter in behind the front with highs north of I-4 staying below 60 degrees. Our coldest morning so far this season will be on Friday. For our inland areas we could see freezing temperatures as far south as Hardee and Desoto Counties with the Nature Coast getting into the mid to upper 20`s. Highs on Friday will stay in the 50`s for almost all of us except SW Florida which could touch 60 degrees for an hour or two in the afternoon. We will slightly warmer temperatures on Saturday before another cold front slides through on Sunday morning. We won`t be seeing any rain with this front but it will bring temperatures back down into the 30`s for most of us Monday morning. Highs on Monday will once again be stuck in the 50`s north of I-4 with the low 60`s everywhere else. && .MARINE... Issued at 233 AM EST Tue Jan 13 2026 Winds will remain out of the north for Tuesday and Wednesday with speeds around 10 knots. We will see a strong cold front slide through Wednesday night that will bring some scattered showers and isolated thunderstorms to the Gulf. Behind it winds will increase quickly peaking at 20 to 25 knots by Thursday afternoon. Winds will not remain that high for long as high pressure starts to move overhead. This will start to decrease the winds late Thursday night and by Friday afternoon should only be around 5 knots. Winds will shift more easterly as the high pressure moves away on Saturday between 5 to 10 knots. && .FIRE WEATHER... Issued at 233 AM EST Tue Jan 13 2026 We will see dry and cooler conditions for our Tuesday and the early part of Wednesday. A strong cold front will push through the area Wednesday night bringing scattered showers to the area. Behind the front we will see breezy conditions on Thursday with gust to 20 to 25 mph. Drier air will filter in Thursday night creating critical RHs by Friday afternoon but winds will have calmed down by then.

Updated at 546 AM CST Tue Jan 13 2026 * Low temperatures just below freezing are forecast for most places that are generally along/north of the I-10/12 corridor Tuesday morning. Freezing temperatures are forecast to last several hours Tuesday morning moving above after sunrise. Residents should take action to protect sensitive vegetation and ensure outdoor pets have access to warm shelter. * According to the National Fire Protection Association, nearly half of all home fires occur between the months of December, January and February, with the increased risk attributed to the use of home heating devices such as portable space heaters and fireplaces. Those planning to use such devices during this cold snap should safety recommendations - such as using a screen and keeping a fire extinguisher near all fire places; and ensuring all space heaters are plugged directly into wall outlets and placed on level surfaces at least 3 ft from any flammable materials. && .SHORT TERM... (Tonight through Wednesday night) Issued at 753 PM CST Mon Jan 12 2026 A slow warming trend will start Tue but will only get into the low to mid 60s by Wed before dropping again to the low 30s north and low 40s south Wed night. This cold front will be able to produce some cloud cover and cloud depths enough to produce some light rainfall in a few locations. This is all it will be able to produce since cloud depth will not be anywhere close enough to produce lightning. Whatever rain it is able to produce will be fleeting mainly Tue night into early Wed. But there is a second chance of a few sprinkles as the secondary frontal sfc catches the first late Wed. This is when the surge of coolest air moves through. The air won`t be frigid but it will be cooler than where we are now. && .LONG TERM... (Thursday through Monday night) Issued at 753 PM CST Mon Jan 12 2026 We should only make it to around 50F for Thu. Then the coldest night for this system will be Thu night into Fri morning with lows in the upper 20s north to mid 30s south. It`s possible to reach the 60s as we warm up after this front but it won`t last long as another in a line of cold air dumps moves through by the weekend. This is the one that is most questionable at the moment and could go either way, wet and stormy or just a few showers moving through. The more detailed features with this won`t be deciphered until Thu at the earliest. We are pretty confident that this front will not take its time in moving through. We should see another warming trend after that as we move into the new week and yet another cold air surge from the north by Tue. This one is questionable to move through, and since it is so far out, there are no clues to if or when. But with the pattern as it is, we are fairly sure that another front moving toward the area in that time frame is a pretty good bet. && .AVIATION...

West winds will rise ahead of a reinforcing cold front moving through late Wed bringing winds around to NW 20-25kt Wed into Thursday. This time frame will likely need small craft advisory headlines again. NW winds will begin to ease again late Thursday into Friday.

Issued at 543 AM CST Tue Jan 13 2026 - Cold temperatures are expected over the next 7 days. Sub- freezing temperatures are forecast across much of the area, especially Thursday night and over the weekend. - Strong northerly winds will occur over the marine area Wednesday night and Thursday, creating hazardous conditions for small craft. && .DISCUSSION... Issued at 1145 PM CST Mon Jan 12 2026 Another cool and dry day is expected for today as high pressure lingers across the area. This high will push southward into the Gulf and weaken as our next reinforcing cold front sweeps through the area Wednesday night. Looking aloft, a southern stream shortwave trough, located over western Texas will quickly approach the local area by tonight. Winds aloft will briefly turn southwesterly as it approaches. Although moisture return is still quite limited (PWATs remain below an inch), there may be enough forcing to squeeze out a few isolated to widely scattered showers as the trough passes overhead during the overnight hours. With the cold airmass still in place, expect a very light, overrunning rain. By the afternoon, longwave troughing diving southward from Canada will phase with the southern stream shortwave and push to our east by Wednesday night. This trough will help to send the aforementioned cold front through our area. Once again, a few light rain showers cannot be ruled out as the front pushes through. Behind it, another cold, dry airmass filters in from the north as high pressure builds in. Highs for today and Wednesday will be in the upper 50s to low 60s. Lows tonight will dip into the upper 30s to low 40s. After the front passes through Wednesday night, temperatures on Thursday will crash into the mid to upper 40s for highs and the low to mid 20s for lows Although winds Thursday night look to be rather light, apparent temperatures may get close to our Cold Weather Advisory criteria. We`ll keep an eye on this potential over the coming days. The second half of the period will be strikingly similar to the first half. By Friday and Saturday, highs will rebound to the upper 50s to low 60s, with lows Friday night ranging from the mid 30s inland to the low 40s along the coast. Another longwave trough is set to dig southward from Canada, helping to send yet another reinforcing cold front through our local area Saturday into Saturday night. Limited moisture return should keep PoPs low, although would not be surprised to see a few isolated showers pop up. After the front passes through temperatures drop once again, with highs Sunday and Monday in the upper 40s to low 50s and lows dropping into the 20s. A Low Risk of rip currents remains in place through much of the period, with a brief bump to Moderate expected Wednesday night for our western Florida Panhandle beaches. /96 && .AVIATION...

Reintroduced rain/snow mentions inland along the cold front Thursday morning, although wintry precip impacts are still not expected. Small craft advisories issued Tuesday night to Thursday for coastal waters from Oregon Inlet to Cape Lookout && .KEY MESSAGES... 1) Cold temperatures this morning with a gradual warming trend today into Wednesday 2) A low pressure system and cold front Wednesday through Thursday night will bring the next chance of rain, with a slight chance of non-accumulating snow 3) Generally dry cold front moves through early Sunday, with another surge of cold, dry air behind it MARINE: SCA conditions Wednesday and Thursday, with gale force winds possible Thursday night. SCA conditions possible again for the weekend. && .DISCUSSION... KEY MESSAGE 1... High pressure centered over the region has allowed for good radiational cooling conditions this morning with light/calm winds and clear skies. Lows expected in the mid to upper 20s inland to 30s along the coast around sunrise. Some inland locations have even dropped into the lower 20s. NBM temps are too warm in this scenario and followed closely to MOS guidance with manual adjustments for the peak radiational cooling locales. High pressure slides offshore today with southwest winds bringing a warming trend with temps climbing to near 60 today and tomorrow afternoon, which is a few degrees above climatology. KEY MESSAGE 2... A robust northern stream trough digs into the eastern CONUS today through Wednesday. An embedded shortwave moving across the Deep South will bring improved upper level forcing and expect an area of low pressure to develop off the Southeast coast Wednesday which will pass off the NC coast Wednesday evening. There continues to be some uncertainty with the exact track of the low offshore which will ultimately determine precip coverage and amounts across the region. The best precip chances will be along OBX and areas offshore where we continue likely PoPs, which tapers to slight chance well inland. Guidance is not that impressive with precip amounts which shows around a quarter of an inch along the coast to little accumulation inland. All liquid precip expected through Wednesday night. A second shortwave moves through the upper trough Wednesday night with an attendant cold front pushing across ENC early Thursday morning. ENC is removed from best upper level dynamics but sufficient moisture remains that we could see a rain/snow mix inland with frontal forcing becoming all rain closer to the coast along the front, but rain amounts expected to be limited, only up to a tenth of an inch at best. Any snow mixed in is not expected to accumulate, and no wintry precip impacts are expected. Strong CAA develops behind the front later Thursday morning but it appears this will be a typical cold air chasing the moisture, likely keeping us dry Thursday afternoon. For this reason, stepped down from NBM chance snow to slight chance, with room to step down even further. The upper level trough axis pushes across the region Thursday evening bringing descent forcing but by this time moisture will be limited. However, coastal locations could see a brief period of rain/snow. Guidance has been trending drier and NBM probs are less than 25% for any accumulation precipitation, for either rain or snow. KEY MESSAGE 3... A deep upper level trough with an associated cold front is expected to move through the region early Sunday. There isn`t much moisture to play with ahead of this front, so precip chance is on the lower side (PoPs 15-20%). NBM called for snow chances, but with sfc temps in the 40-45F range at that time, paired with the drier trend, elected to stick with all rain for the forecast. Behind the front, below average temps and dry conditions return. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... No changes in forecast thinking as VFR conditions are forecast through the entire period as high pressure builds in from the southwest. Light and variable to calm winds this morning become SW`rly at about 5-10 kts with gusts up around 10-15 kts by midday. These winds will persist into Tue evening before winds become light and variable once again Tue night. Skies remain partly cloudy through the period. While currently not in the TAFs on this update, monitoring the forecast for potential LLWS impacts in ENC late tonight into Wed morning. While it is a low threat, some guidance is showing some LLWS impacting portions of ENC late tonight as a mid level shortwave moves through the area. If confidence increases in its occurrence, a line for this may be included in the TAFs in the coming updates. Outlook: Pred VFR flight cats expected through much of the period with high pressure in control. While there is still uncertainty, a low pressure system Wednesday and Thursday could bring precip, lower ceilings, and gusty winds with it. && .MARINE... High pressure has settled across the waters bringing W/SW winds around 5-15 kt becoming SW later as high moves offshore. Seas have also laid off, around 2ft across all coastal waters. Tonight, winds begin to pick up as a low crosses the great lakes and high pressure sits offshore, tightening the pressure gradient. This will bring gusts around 25kts for the warmer gulf stream waters tonight. Issued a SCA for gulf stream waters given 6Z guidance increased confidence in SCA gusts. For now have SCA going until Friday 00Z, at which point gale force gust chances increase. Winds briefly lessen to 15-20 knots Wednesday morning for 3-6 hours before picking back up to 20-30 knots as a low forms offshore and strengthens. Again, best chance of seeing small craft gusts with this low is along warmer gulf stream waters with SW flow. Cooler inland sounds/rivers will see much lighter wind gusts with the SW winds thanks to a marine inversion. A cold front will push across the waters Thursday morning with strong CAA developing Thursday afternoon and Thursday night and could see NW winds bring strong SCA to Gale Force conditions across the waters. Conditions improve late in the week with high pressure briefly building into the area. This weekend, another cold front moves through, bringing elevated winds and seas once again. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.

| #1257062 (Received by flhurricane at: 6:48 AM 13.Jan.2026) AFDILM Area Forecast Discussion National Weather Service Wilmington NC 634 AM EST Tue Jan 13 2026 .WHAT HAS CHANGED... In the near term, no major changes coming down the track as we approach 7 AM EST. Updated 12Z TAF discussion below. All other previous discussions still apply. Forecast lows Thursday night have been adjusted colder, but wind chills are little changed. && .KEY MESSAGES... 1) Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. 2) Light rain is possible Wednesday as an upper level system moves overhead. 3) A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. && .DISCUSSION... KEY MESSAGE 1...Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. Some good radiational cooling has occurred just past midnight, as temperatures continue to dip towards the 20s. Some cirrus that is streaming in from the west has thickened up over the last hour or so, which I believe has already started to hinder the cooling. May need to back off on some of the hourly temperature forecasts as we head through the rest of this morning. Elsewhere, quiet forecast still in store through tonight. A shortwave moves through late this morning, but doesn`t really do much at all to change the sensible weather. Plenty of sunshine on the way, with highs creeping up into the upper 50s to near 60. This will solidly be 10-12 degrees warmer than yesterday, about a degree or two above normal for mid-January. Southwesterly flow starts building in tonight ahead of the next disturbance. This causes low temperatures to be considerably warmer than the last couple of nights, generally in the mid-to-upper 30s inland, lower 40s at the coast.here. KEY MESSAGE 2...Light rain is possible Wednesday as an upper level system moves overhead. A southern stream shortwave will be pulled northeastward and across the Carolinas on Wednesday by a deep upper level trough developing across the Great Lakes. This shortwave will carry a slug of mid level moisture with it, visible on model 700 mb progs between 15z Wednesday and 00z Thursday. Isentropic analysis within the moisture-bearing layer shows only modest upglide, but still likely enough to produce light rain with less than 0.10 inches expected. Forecast PoPs have been tweaked higher to 40-50 percent along the coast centered on Wednesday afternoon. Very dry air between the mid level cloud base and the surface means there could be evaporational cooling as precipitation begins. I`ve kept Wednesday`s forecast highs near the NBM for now, but there`s certainly potential that highs will come in lower than is currently forecast if precipitation is more widespread or heavier in intensity. KEY MESSAGE 3...A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. Strong cold advection behind Thursday`s early morning arctic cold front will continue through the day and into Thursday night. Although yesterday morning`s models showed a decrease in wind speed late Thursday night, the new 00z models arriving now show this decrease in wind even more acutely. This should allow a radiational inversion to develop, especially inland, and we`ve accordingly pushed forecast lows down another couple of degrees. We`re now expecting lows in the upper teens with some lower 20s near the coast. This looks to be the second coldest arctic outbreak of the winter (so far) behind the December 15, 2025 event. In terms of public impact, lower forecast temperatures are being offset by lighter forecast winds. Forecast wind chill temperatures are still near the 15 degree threshold needed for a Cold Weather Advisory late Thursday night/Friday morning. Although model spread widens by the weekend, a second arctic cold front appears likely to arrive across the eastern Carolinas either Saturday night or Sunday morning. This will be followed by another shot of well below normal temperatures early next week. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... High confidence in VFR through the 12Z TAF period. Calm winds in place at all terminals, which will continue for the next several hours. Light breeze at 5-7 kts out of the SSW builds in by 17-19Z this afternoon, decreasing slightly to 4-6 kts by sunset. Extended Outlook...VFR through perhaps midday Wednesday. Some restrictions are possible late Wednesday and Thursday. VFR returns Thursday night through Saturday. && .MARINE... Through Tonight...NNW winds around 5 kts back to the southwest by late this afternoon, increasing towards 10 kts by sunset. Winds veer slightly to the WSW overnight tonight, increasing more to 10-15 kts. Seas remain at 1-2 ft. Wednesday through Saturday Night...Breezy southwest winds as strong as 20-25 knots Wednesday night will precede a strong arctic cold front that will push off the North and South Carolina coastline early Thursday morning. Northwest winds behind the front on Thursday into Thursday night should average 20 to perhaps 25 knots. There is a good chance a Small Craft Advisory will be needed for the winds both ahead of and behind the cold front. High pressure building eastward along the Gulf Coast should lead to diminishing wind speeds Friday, however the high should push offshore Friday afternoon or evening with winds shifting southwesterly and increasing to 15-20 knots. Winds could increase further on Saturday when a second period of Small Craft Advisory conditions could occur ahead of the next front approaching from the west. && .ILM WATCHES/WARNINGS/ADVISORIES...

Issued at 320 AM EST Tue Jan 13 2026 - A couple degrees warmer today with isolated showers, mainly Cape Canaveral southward - Strong cold front arrives Wednesday night into Thursday morning, bringing a brief increase in rain chances - Below normal temperatures Thursday onward; sub-freezing morning lows and frigid wind chills in the 20s to 30s, especially Friday morning and next Monday morning && .DISCUSSION... Issued at 320 AM EST Tue Jan 13 2026 Today-Tonight...An inverted surface trough remains just offshore this morning while a low cloud deck persists over the northern half of the area. The most recent cold front to move through ECFL has settled across the Florida Straits as a stationary front. Current temperatures range widely from the low/mid 50s north of Orlando to the upper 60s along the Treasure Coast. Where moisture remains marginally sufficient today, mainly over the Treasure Coast and Gulf Stream, isolated showers will be possible. That said, a majority of the area will stay dry with temperatures warming a few degrees more compared to yesterday (highs in the low/mid 70s). Moisture return and the south Florida front moving north helps to expand 20-30% rain chances northward overnight, but the majority of activity will be focused out over the Gulf Stream. In other words, a continuation of isolated showers will simply expand north toward Cape Canaveral and even the Volusia Coast through daybreak Wednesday. Lows tonight are forecast to settle into the mid 50s north to the low/mid 60s from the Orlando metro to the Treasure Coast. Wednesday-Thursday...Wednesday morning, a weak cool front looks to be draped across portions of the Treasure Coast and Gulf Stream waters, before sliding east of the area by midday. Our focus is on the next series of cold fronts, approaching central Florida late Wednesday night into Thursday morning. 500mb height falls begin in earnest late Wednesday afternoon as a trough deepens over the eastern U.S. Rain chances look limited Wednesday, with one batch of QPF shifting well offshore and models in disagreement on very light QPF north of Orlando in the afternoon. We will be waiting on the arrival of a stronger cold front early Thursday, bringing with it slightly better rain chances (30-55%). Model guidance lends to a little lower confidence than is typical at this time range. GFS+AI ensembles point to generally 0.2" or less of measurable rain between now and the FROPA Thursday morning, whereas the ECMWF+AI ensembles are more centered around 0.3"-0.4" of rain. Granted, a couple tenths of rain is not a huge difference with most of the area under D0-D1 (abnormally dry to moderate drought) conditions. As quickly as rain moves in, it will move out over the open Atlantic Thursday afternoon. A westerly breeze Wednesday under a mostly cloudy sky is likely to keep temperatures a bit cooler, especially north of I-4. Behind Thursday`s front, noticeably colder and drier will rush southward supported by a 10-15+ mph wind (gusting 20-25 mph at times, especially at the coast). Highs in the upper 60s to mid 70s Wednesday trend down on Thursday, struggling to reach the 60-degree mark Orlando northward. Skies quickly clear Thursday night, setting the stage for a cold night and brisk wind chill values. Friday-Monday...Before stepping outside for work or school Friday morning, be sure to dress warmly! Forecast morning lows have not changed much from the previous cycle, maintaining the idea of temperatures at or below freezing along and north of I-4, in addition to sub-freezing lows across interior ECFL as far south as Lake Okeechobee. Making it feel even colder will be a northwest breeze, sending wind chill values into the mid/upper 20s for a majority of the area. As a result, a Cold Weather Advisory will be needed for a large portion of ECFL Friday morning. Winds decrease through the day Friday into early Saturday as high pressure builds over the peninsula. Despite plenty of sun Friday afternoon, temperatures will really struggle to get out of the 50s from Osceola/northern Brevard and points north (low 60s south). Mostly clear conditions Friday night sets the stage for another cold night (30s-mid 40s). With lighter winds overnight, there is a possibility of frost developing Saturday morning over portions of the area. Daytime temperatures make a comeback, climbing into the 60s to low 70s. But then... Below normal temperatures look to be reinforced by another cold front Saturday night into Sunday. A lack of moisture along this front is keeping rain chances out of the forecast. Temperatures swing colder again Sunday into early next week, with lows in the 30s to mid 40s and highs only in the 50s and 60s. Sub-freezing temps are possible again, especially Monday morning. Behind the front, northwest winds will again add a wind chill factor with values falling into the mid 20s to low 30s Monday morning. && .MARINE... Issued at 320 AM EST Tue Jan 13 2026 Weak surface trough remains over the nearshore waters through tonight as N-E winds decrease today. Isolated showers are forecast along the Treasure Coast and over the Gulf Stream, expanding north and eastward in time, especially on Wednesday. Seas fall to 3-4 ft today and 2-4 ft Wednesday. A strong cold front approaches early Thursday morning, quickly pushing south of the waters by the afternoon. Shower chances increase to 40-60%, followed by freshening NW winds behind the front. Poor to hazardous boating conditions gradually expand from the offshore waters Thursday morning to the remaining marine legs Thursday afternoon. NW winds 20-25 kt with gusts around 30 kt (esp. offshore) build seas to 4-7 ft nearshore and 6-9 ft offshore Thursday night. The pressure gradient quickly unwinds Friday as high pressure builds overhead, allowing seas to fall to 3-6 ft Friday afternoon.

| #1257059 (Received by flhurricane at: 6:36 AM 13.Jan.2026) AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 625 AM EST Tue Jan 13 2026 .WHAT HAS CHANGED... Model trends continue to favor a more progressive (faster) and drier solution for the late week system. This translates to a lower chance for accumulating winter precipitation Thursday morning. && .KEY MESSAGES... 1) Remaining dry, while trending breezy and milder today through Wednesday. 2) Low pressure develops along an approaching cold front Wednesday night, and passes by to the N/NE of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of snow showers Thursday morning. Little to no snow accumulation is expected. 3) Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. && .DISCUSSION... As of 625 AM EST Tuesday... KEY MESSAGE 1...Remaining dry and trending breezy and milder today and Wednesday. Strong sfc high pressure (~1030mb) is centered over the Gulf coast, ridging ENE into the local area will build south across the southeast today, as low pressure over central Canada remains well north of the local area. SSW return flow becomes a bit stronger today, allowing for highs to warm up quickly into the 50s under a mainly sunny sky. A few readings around 60 degrees are possible across south central VA and NE NC. A few clouds cross the area tonight and early Wednesday ahead of the cold front associated with the northern stream system, but otherwise mainly clear and not as cold tonight with lows in the 30s. Despite some increasing mid to high clouds Wednesday, mild return flow will provide highs well into the 50s west of the bay again on Wednesday (low to mid 50s Lower Eastern Shore), with highs near 60 degrees far SE counties. KEY MESSAGE 2...Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of light snow Thursday morning. 00z/13 models continue to advance a faster, drier solution for the late week system. A potent northern stream shortwave will dig south from the Ohio Valley into the northern mid- Atlantic late Wednesday through Thursday, as a dampening southern stream shortwave traverses the Gulf coast. Our area will be in between these features, with the resultant subsidence allowing for rapid drying and therefore lower QPF. There is still a chance for some light overrunning moisture to cross the area, along and (mainly) behind the crossing cold front Wed night. Precipitation will mainly fall in the form of light rain showers. While the faster arrival of colder air would allow for a changeover to snow showers as precipitation tapers off early Thursday morning, it is increasingly apparent that the colder air will be chasing the departing moisture, with the developing surface low crossing near of just south of the Mason-Dixon line as it exits to the NNE. This is a pattern that rarely results in any tangible snowfall across most of our region. For its part, the latest NBM remains a bit higher than latest model consensus, likely still at least in part reflecting the previous model consensus of this past weekend. Would therefore not be surprised to see these chances drop off completely as we get closer. Thus, while some light snow is possible before precipitation tapers off, have removed any snow accumulations from the digital database and expect very limited to no impacts from snow with this system. KEY MESSAGE 3...Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. Becoming rather cold and breezy/windy in strong cold advection in the wake of the Arctic frontal passage Thursday. Look for highs to struggle to get out of the 30s N and in the 40s S, even w/ diminishing cloud cover. Cold w/ lows in the teens and 20s Thu night. Even as winds diminish, wind chills in the teens are expected Friday morning. Not quite cold enough for Cold Weather Advisories but close, and certainly a stark contrast from the warmer temperatures expected today and tomorrow. The rest of the extended period will primarily feature below normal temperatures and mainly dry conditions. An upper level ridge persists across the west coast of North America, keeping an upper level trough in place from central Canada into the SE CONUS, with resultant NW flow allowing for another influx of Arctic air in the wake of a second, reinforcing Arctic frontal passage over the weekend. Guidance is still keying in on a pair of weak disturbances, one ahead of and one just behind that next strong cold frontal passage. At this point, the "best" chance for any precipitation looks to be on Sunday, though PoPs remain low at only 15-20%. The overall pattern still appears too progressive to tap into any southern stream moisture, reinforcing the developing cold, dry pattern. Another round of cold temperatures follows behind that front for Sunday night through early next week, with highs in the 30s and lows in the teens to low 20s. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... As of 625 PM EST Monday... VFR conditions currently across area terminals will prevail through the 12Z/13 TAF period. Light W-SW winds average 5-7 kt early this morning under a mainly clear sky. Expect SW winds to increase a bit late this morning, gusting to 15-20 kt by the afternoon. Outlook: Dry/VFR conditions are expected across the mid-Atlantic through midweek. Increasing low-level wind shear is expected ahead of an approaching cold front late this evening into Wed afternoon. The front will cross the region Wed evening, with some light rain showers possible behind the front late Wed night into Thursday morning. A brief period of sub-VFR conditions will be possible early Thu morning, as a secondary front crosses the region, ushering in a much colder airmass for the late week period into the weekend. && .MARINE... As of 220 AM EST Tuesday... Key Messages: - SCA conditions expected tonight due to gusty SW winds. - A series of cold fronts will cross the region late this week with strong SCA conditions possible Thursday into Friday. High pressure is situated south of the waters this morning. SW winds are generally 10-15 kt with occasional gusts to 20 kt, but these winds will subside later this morning into this afternoon. The aforementioned high translates offshore by this evening as strong low pressure advances through SE Canada, tightening the pressure gradient over the area. In addition, a SW low-level jet still looks to overspread the waters tonight into Wednesday morning. Southerly flow picks up again this afternoon but should remain sub-SCA until ~00z/7 PM this evening. After 00z, winds become SW and increase to 15-20 kt on the Chesapeake Bay with some potential for 20-25 kt sustained winds on the coastal waters N of Parramore Island. Gusts up to 25-30 kt are also expected. Small Craft Advisories have been issued for the Chesapeake Bay and coastal waters N of Cape Charles through mid-morning Wednesday. Sub-SCA SW flow should then prevail later Wednesday into the first part of Wednesday night. A strong cold front is then expected to swing through the region early Thursday morning as low pressure develops over New England. This front will bring an abrupt wind shift to the NW, along with a substantial increase in the wind speeds to 20-25 kt for most of the waters. These elevated winds likely persist into Thursday night as cold air advection maximizes. An additional round of Small Craft Advisories are very likely during this period. While forecasted gusts currently fall just shy of Gale-force, cannot rule this out on the ocean and will continue to monitor over the next few forecast cycles. Winds quickly subside around sunrise Friday morning before elevated SW flow potentially returns Friday night/Saturday morning ahead of another cold front. The current model consensus pushes this front through overnight Saturday and additional SCA headlines are probable as winds become NW. Seas are 2-3.5 ft this morning, with 1-2 ft waves in the bay. Seas and waves increase to 3-5 ft and 2-3 ft, respectively, tonight through Wednesday morning. Elevated seas and waves return early Thursday morning and continue into Thursday night in the wake of the cold front. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.

Issued at 1052 PM CST Mon Jan 12 2026 A weak southern stream upper low is currently near the Big Bend region. It will move eastward across the state Tuesday and Tuesday night as it becomes absorbed into an amplifying trough across the central and eastern CONUS. Local radar echoes have been mainly virga so far, but a couple stations near and southwest of Corpus Christi have reported a trace-0.01" of light rain. That batch of light rain may brush areas near the coast overnight. Better lift arrives with the upper low during the day on Tuesday along with the left-exit region of an upper-level subtropical jet streak. Mid-levels will be fairly saturated, but dry air will remain in place at low-levels. Expect at least some sprinkles to move through during the day with a low chance of light measurable rain at any given location. Associated cloudcover will knock at least a couple degrees off of high temperatures. A highly amplified upper-level pattern will be in place through the end of the week and into the weekend, with ridging along the West Coast and a deep trough over the eastern CONUS. Several shortwaves will reinforce the eastern CONUS trough. Southeast Texas will be underneath dry, generally northwesterly flow aloft along the back side of the trough. Two dry frontal passages are expected Wednesday afternoon and Friday night with brief warm-ups prior to the fronts with southwest winds, followed by an increase in northerly winds behind the fronts. Some de-amplificiation of the pattern may take place by early next week. JDavis && .AVIATION... (12Z TAF Issuance) Issued at 516 AM CST Tue Jan 13 2026 VFR conditions will prevail with BKN to OVC mid and high level clouds passing through the region. There will be a chance of isolated, light showers developing during the afternoon hours today. Winds today will be southwesterly around 5-8kt, become variable overnight, and then return to southwesterly during the morning on Wednesday. A cold front will be passing through the region Wednesday afternoon ushering in a north-northwesterly wind shift. Fowler && .MARINE... Issued at 1052 PM CST Mon Jan 12 2026 Mariners should anticipate negative tide levels through the week, especially around low tide cycles in the central and northern half of the the bays. Will maintain the Low Water Advisory in place, though values will probably fall just short of criteria (-1 MLLW) Tuesday morning. A Wednesday daytime frontal passage will push additional water out of the bay, with another Low Water Advisory likely being needed for Thursday morning. Mariners should be cognizant of grounding risks. Light winds and low seas are expected Tuesday with a low chance for light rain. The next front is expected to push into the waters Wednesday afternoon with increasing northwest and north winds filling in behind it Wednesday night into Thursday. A Small Craft Advisory will likely be needed during this time period. JDavis && .PRELIMINARY POINT TEMPS/POPS...

Issued at 615 AM EST Tue Jan 13 2026 - Below normal temperatures are expected for several days behind a strong cold front on Wednesday. Friday morning will be the coldest this week with a medium to high chance (60-80 percent) of an inland hard freeze (25F or lower). - Hazardous marine conditions will develop behind the next cold front on Wednesday night and Thursday with a medium to high chance (60-80 percent) of gale force northwest wind gusts west of Apalachicola. && .SHORT TERM... (Today and Tonight) Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis across the area today will lead to mostly clear to partly cloudy skies with just some passing high cloud cover. Afternoon highs will generally range from the upper 50s to mid 60s with overnight lows ranging from the mid 30s to mid 40s. && .LONG TERM... (Wednesday through Monday) Issued at 228 AM EST Tue Jan 13 2026 Two reinforcing cold frontal passages are expected. The first one will arrive starting late Wednesday, and the second one will arrive on Saturday or Saturday night. There will probably be some scattered light showers in advance of the front on Wednesday, but moisture will be limited with both fronts. Any rain that occurs will be on the light side. Breezy conditions are likely on Thursday behind the first front with peak gusts in the 25-35 mph range. The main impact to the local area will be cold temperatures. There is a medium to high chance of a hard freeze (25F or lower) for inland areas on Friday morning. Additional light freezes are expected for portions of the area each morning thereafter into early next week. Despite all the cold temperatures, there is currently no wintry precip expected in our area. && .AVIATION... (12Z TAFS) Issued at 615 AM EST Tue Jan 13 2026 Smoke from a nearby prescribed burn has lead to restrictions less than a mile in haze at TLH early this morning. As of this time, haze has subsided, but cannot rule out a brief return. Surface high pressure ridge axis gradually moves south of the terminals today. Light and variable winds become north today with a tendency to become more westerly at DHN and ECP during the afternoon. With the weak pressure gradient in place, winds generally AOB 5 kts. VFR w/SCT cirrus becoming BKN late today. && .MARINE... Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis will move south directly across the waters by this evening, bringing a continued decrease in wind. Once high pressure moves further south on Wednesday, westerly breezes will freshen in advance of a strong reinforcing cold frontal passage on Wednesday night. Northwesterly gusts near gale force will follow that front on Thursday with the strongest winds west of Apalachicola. Winds will quickly decrease on Thursday night and Friday as a high center passes directly across the waters Friday evening. Yet another cold front will cross the waters on Saturday evening. && .FIRE WEATHER... Issued at 228 AM EST Tue Jan 13 2026 The high pressure center at the heart of the existing dry air mass will pass directly across the districts today. This will result in a combination of places with critically low humidity below 25 percent and low daytime dispersion due to the lack of wind and low mixing heights. On Wednesday, dispersion will increase markedly with higher values resulting from development of gusty southwest winds in advance of a strong reinforcing cold frontal passage late Wednesday. Strong gusty northerly winds will follow that front on Thursday, supporting another day of high dispersion. && .HYDROLOGY... Issued at 228 AM EST Tue Jan 13 2026 No flooding is expected for at least the next 7 days. Any rain that falls in the next week will not be hydrologically significant.

Updated at 611 AM EST Tue Jan 13 2026 - Occasional showers continue today favoring east coast metro areas. - Hazardous winds and seas in the Atlantic will improve today. - Another strong cold front could drop across the peninsula on Thursday, bringing reinforcing cold air and more increased rain chances. && .SHORT TERM... (Today through Wednesday) Issued at 300 AM EST Tue Jan 13 2026 Latest ensembles and global model solutions show a decaying sfc boundary lingering over SoFlo today, and maybe lifting a little northward. This will require keeping some POPs through early this evening, 20-30 percent, favoring the eastern side of SoFlo. 00Z MFL sounding and model data keep PWATs in the 1.3-1.5" range, for which potential for isolated rainfall amounts of 1" still remains in the forecast. By Wednesday, models show a mid lvl shortwave feature moving around the base of a deepening trough over the SE CONUS. Both systems are shown migrating eastward, with overall synoptic flow veering more southwestward/westward by the afternoon hours. This will further focus highest chances of rain over the Atlantic coastline and around the Broward/Palm Beach metro areas. Meanwhile, a more robust sfc cold front will be pushed southward towards northern Florida by late Wednesday. High temperatures for the short term should remain in the upper 70s to near 80, with overnight lows tonight mainly in the low 60s, with some mid 60s around the east coast metro areas. && .LONG TERM... (Wednesday night through Monday) Issued at 300 AM EST Tue Jan 13 2026 Model consensus depict a FROPA reaching the area on Thursday, with rain chances increasing in the Wed night-Thu morning time frame ahead of the front. Latest timing with this feature places the best chances of showers during the mid/late morning hours on Thursday with scattered to numerous showers possible. In general, dynamic support seem to remain poor as the parent trough/low complex will continue to pull NE into the eastern seaboard. And with prevailing cloud cover, the daytime heating component should remain weak enough to keep mention of thunderstorms out of the forecast attm. This, however, will continue to be revised and updated as necessary. 50-70 POPs remain in the forecast for Thursday morning. Winds veer northward Thursday night into Friday as broad high pressure spreads across the SE CONUS, triggering another cold/dry air advection event. Coldest temperatures with this robust cold air mass are expected Friday morning before sunrise, with coastal areas dropping into the upper 30s to mid 40s, and interior/northern areas in the low-mid 30s. Friday afternoon will also remain fairly cool for being SoFlo, with highs struggling to hit the mid-upper 60s. Temperatures then gradually warm up during the weekend, but still remaining around the low 70s in general. Then by Monday, models seem to suggest another possible cool down with a front approaching the area. There is still a lot of uncertainty in long range guidance, so the forecast philosophy beyond the weekend will continue to be updated with new guidance. && .AVIATION... (12Z TAFS) Issued at 611 AM EST Tue Jan 13 2026 Borderline IFR ceilings for a couple hours across the east coast metro and then MVFR ceilings should be prevailing after 13Z through much of the day with some scattered showers possible. ENE winds around 10 kts today, with a westerly Gulf breeze developing at APF this afternoon. Winds will be light and variable late tonight. && .MARINE... Issued at 300 AM EST Tue Jan 13 2026 Hazardous boating conditions will continue until later this morning, then conditions will quickly subside and remain below highlight criteria through the middle of the week.

Updated at 506 AM CST Tue Jan 13 2026 * Mainly dry and tranquil weather pattern with seasonable temperatures are expected to persist through next Tuesday. * A cool front is expected to sweep through the region Wednesday night into Thursday and could bring adverse to hazardous marine conditions. && .DISCUSSION... Issued at 1025 PM CST Mon Jan 12 2026 A mainly dry and tranquil weather pattern is expected across Deep South Texas through the forecast period or through next Tuesday. At least one cool front is on track to sweep through the region mid week. Through tonight, any lingering showers, which have mainly been confined to the Northern Ranchlands and areas west of IH-69E, will gradually come to an end from the west to east. Forecast models and ensembles continue to depict a major large- scale weather pattern change taking place midweek this week. The 500 mb pattern is expected to become highly amplified and will feature a dipole type pattern (warm/hot West U.S. vs. a cool/cold East U.S. alignment) with anomalously strong ridging over the eastern Pacific Ocean into western Canada/U.S. and anomalously strong troughing downstream over central and eastern U.S. This pattern coincides with a negative Eastern Pacific Oscillation/-EPO, a positive Pacific North America Oscillation/+PNA, and a negative Arctic Oscillation/-AO as models suggest. That said, at least one cool/cold front is expected to sweep through the region mid week this week. Ahead of this cool front and still under a northwest flow regime at the sfc and aloft, Tuesday will feature seasonable temperatures with highs in the mid 60s to lower 70s. Wednesday will be one of the warmer days of the forecast period thanks to a bit more sunlight or incoming solar radiation compared to prior days. High temps will top out in the upper 70s to lower 80s across Deep South Texas. The dry continental cool front is expected to pass through the region Wednesday night into Thursday. This will result in slightly cooler temperatures on Thursday with highs returning to near seasonable levels (upper 60s to lower 70s). High temperatures rebound on Friday as a return flow develops out of the south. High temperatures are expected to top out in the mid 70s to near 80F degrees along the RGV. There`s a bit more uncertainty in whether or not a second cool/cold front makes its way down to the valley later this week. That said, temperatures have trended warmer over the past 24 hours acknowledging the fact that the second front may not make it`s way all the way down to the valley. We`ll continue to monitor trends in the days ahead. That said, high temperatures Saturday through Tuesday will top out in the 70s. Overnight low temperatures through much of the forecast period will be in the 40s and 50s. && .AVIATION... (12Z TAFS) Issued at 506 AM CST Tue Jan 13 2026 VFR conditions are expected to prevail through the TAF period with light northerly winds. && .MARINE...

Highs Wed in the 40s to near 50. - Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. - Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. && .DISCUSSION... KEY MESSAGE 1...Overall quiet weather today, followed by a period of showers late tonight across interior southern New England with some snow showers confined to the very highest terrain. A series of shortwaves quickly move from west to east tonight along zonal flow. First disturbance passes with little impacts outside of an increase in mid and high level clouds this morning across northern MA. Milder day follows as a transient ridge axis develops over New England. Latest guidance still shows a milder day on tap as 925mb temps climb to 0- 2C. A more amplified shortwave digs over the Great Lakes later Tuesday into Tuesday night. First sign of its approach will be increasing mid and high level clouds later today. Should see a broken band of precipitation pass through the CWA with the higher POPs located across northern Massachusetts. Much of the forcing with this shortwave will be confined to Northern New England and so shower activity will be limited in coverage and intensity. May also see a few flakes mix in across the higher terrain but accumulations if any will be light with marginal temperatures and modest QPF. KEY MESSAGE 2...Mild weather Wed into Wed night with a few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. Highs Wed in the 40s to near 50. An amplifying shortwave trough moves across the Great Lakes and into northern New England Wed into early Thu. Out ahead of this cold front/amplifying shortwave trough...southerly flow will result in unseasonably mild temperatures. Despite considerable clouds...high temps will be well into the 40s to near 50 in a few spots. These readings are a solid 10+ degrees above normal for mid January standards. Given the bulk of the dynamics passing to our north...not expecting a lot of precipitation and much of this time will feature dry weather. Nonetheless...a few showers will be possible at times Wed into Wed night with the focus for them across interior southern New England closer to the shortwave energy. As colder air begins to work in from the west...may see precipitation end as a brief period of light snow showers across interior southern New England early Thu morning. Any snow accumulations should be a dusting to generally less than 1 inch. KEY MESSAGE 3...Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. Low pressure will rapidly intensifies Thu into Thu night as it tracks northeast from northern new England into the Canadian Maritimes. The result will be a shot of much colder air working into southern new England Thu into Fri. Temps on Thu will likely fall during the afternoon into the upper 20s and 30s on a stiff gusty west wind. Low temps Thu night will drop into the upper single digits and teens. Wind chills will drop to between 5 below and 10 above by daybreak Fri. High temps on Fri will only recover into the upper 20s and lower 30s. High pressure building in from the west will keep our weather dry...despite the cold temperatures. KEY MESSAGE 4...Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. High pressure quickly moves east of the mid-Atlantic coast to start the weekend as another trough gets carved out across the Great Lakes. This allows for a quick rebound in temperatures with highs mainly in the 40s on Sat. The forecast then becomes quite complex Sat night into Sunday with an amplifying trough to our west with several pieces of shortwave energy. The problem is that the guidance is struggling on which piece of energy to amplify and where the actual surface low develops. Latest guidance tends to develop the main surface low too far north and late for a significant storm. That being said...there are a few pieces of guidance including the CMC/ICON that have a wave of low pressure further south with the potential for an inverted trough setup. So while a significant storm appears unlikely...given the amount of shortwave energy to our west we can not rule out period of snow sometime Sat night into Sun if an inverted trough sets up. Whether or not this happens remains to be seen...but it is something to watch in the coming days. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... Forecaster Confidence Levels...

| #1257052 (Received by flhurricane at: 6:06 AM 13.Jan.2026) AFDCHS Area Forecast Discussion National Weather Service Charleston SC 602 AM EST Tue Jan 13 2026 .WHAT HAS CHANGED... The first key message was updated to mention only this afternoon for low relative humidity values. For the second key message, wind gusts should remain within Small Craft Advisory levels Thursday into Thursday evening. The risk for Gale force wind gusts has diminished. && .KEY MESSAGES... 1) Dry high pressure will remain across southeast Georgia and South Carolina today, yielding low relative humidity values this afternoon. 2) Dangerous fire weather and marine conditions possible as gusty winds and low humidity values arrive behind a mostly dry cold front Thursday into Friday. 3) Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. && .DISCUSSION... KEY MESSAGE 1: Dry high pressure will remain across southeast Georgia and South Carolina today, yielding low relative humidity values this afternoon. Dry sfc high pressure will linger across the Southeast U.S. today. Forecast soundings indicate that mixing will range between 2.5 to 3 kft this afternoon. As mixing begins, sfc dewpoints should remain in the 20s through mid-day. However, weak southwest winds may result in a slow increase in dewpoints from south and near the coast, increasing into the 30s. Minimum RH values should occur during the early afternoon hours, before the dewpoint recovery. Min RH values are forecast to range from the mid 20s inland to the mid 30s along the coast. High temperatures are forecast to range around 10 degrees warmer than values reached on Monday, generally in the low 60s. KEY MESSAGE 2: Dangerous fire weather and marine conditions possible as gusty winds and low humidity values arrive behind a mostly dry cold front Thursday into Friday. On Thursday a rex block will be established over the Western United States allowing for a long wave trough axis to amplify across the Eastern United States. In the mid-levels of the atmosphere, a closed mid-level low will be moving east across the Great Lakes with a strong push of lower heights approaching the area from the west (120 m height falls in 12 hrs). This magnitude of DCVA/ height falls is rather impressive, but precipitation chances are limited (<15%) with the surface cold front Thursday morning/ afternoon. There are several reasons for this. The main reason being the Wednesday wave. This wave will be moving away early Thursday with the LFQ of the subtropical jet streak moving off of the coast. During this type of setup, most of the precipitation gets going off of the South Carolina/ North Carolina coast. Behind the surface cold front, strong low level CAA will take hold with 850 mb temperatures dropping from 0 degrees C to -8 degrees C. This, in combination with peak mixing and downslope flow in the low and mid levels, will likely result in wind gusts Thursday afternoon on the higher end of the guidance envelope, with 25 to 30 mph gusts likely, with some gusts to 35 mph possible over land. A Lake Wind Advisory will likely be necessary with probabilities of reaching 25 kt around 55%. Additionally, dewpoints will rapidly fall behind the cold front allowing relative humidity values to approach 25%. It should be noted that the Wambaw and Glissons Pond RAWS sites have both had fuel moisture values in the single digits Sunday and Monday afternoons. Surface high pressure will settle overhead Friday, with dewpoints likely mixing out to near the single digits in the afternoon. The latest LREF probabilities show a 50 - 70% chance of RH values less than 25% away from the immediate coast. Winds will be much weaker Friday though given the proximity of the surface high pressure to coastal South Carolina and Georgia. KEY MESSAGE 3: Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. Surface high pressure now looks to move east faster, or allow winds to decouple quicker Thursday night/ Friday morning. As such, low temperatures will likely be in the upper teens for areas of rural Georgia away from the coast (and closer to the surface high pressure), and low 20s for the rest of coastal South Carolina. Right at the beaches (including the Charleston Peninsula), expect lows in the upper 20s. Wind Chill to temperature spread will likely be greatest Thursday evening, with the differential becoming less and less as winds slacken by Friday morning. Still though, enough wind is forecast that a Cold Weather Advisory might be required for some of the area Friday morning. Rural Georgia has ~ a 60- 80% chance of needing a Cold Weather Advisory, while coastal South Carolina and Georgia has ~ a 20-50% chance of needing a Cold Weather Advisory. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... VFR conditions will prevail at CHS/JZI/SAV terminals through 12Z Wednesday. Extended Aviation Outlook: VFR conditions will continue for KCHS, KJZI and KSAV through late week. NW winds could gust to around 20 kts in the wake of cold front. && .MARINE... Broad high pressure will remain across the marine zones today and tonight. The pattern should yield around 5 kts of wind today, gradually increasing to 5 to 10 kts tonight. Seas are forecast to remain between 2 to 3 ft. Wednesday, the marine zones will remain between a developing low pressure system over the Gulf Stream and a cold front over the western Carolinas. A weak gradient on the west side of the low keeps benign marine conditions in place despite increased shower chances. A strong cold front will cross the area Wednesday night. Northwest winds should develop in the wake of the front, with gusts around 25 kts across the Atlantic waters of GA and SC on Thursday into Thursday evening. As a result, wave heights will build during the daylight hours on Thursday, peaking between 3-5 ft across the nearshore with 6ft beyond 30 NM Thursday evening. Small Craft Advisories will likely be needed for all marine zones outside the CHS Harbor Thursday and Thursday evening. The center of a large area of high pressure will arrive on Friday, supporting winds around 10 kts with 1-2 ft seas. Winds should gradually strengthen as a dry cold front sweeps across the region on Saturday, with gusty winds and building seas, possibly reaching Small Craft Conditions across a portion of the waters. && .CHS WATCHES/WARNINGS/ADVISORIES...

For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Several Freeze Events through Early Next Week. Friday Morning Hard Freeze Inland & Coastal Light Freeze Likely. - Dangerously Cold Wind Chills in the teens to low 20s Possible. Consecutive Nights of Inland Freezes Fri Night through Next Tue Night - Small Craft Advisory & Gale Force Gusts Thu & Thu Night && .NEAR TERM /THROUGH TONIGHT/... Low level cloudiness and elevated northerly winds near the coast will gradually decrease this morning as a coastal trough over the local Atlantic waters edges farther east. A few sprinkles will be possible, mainly across northeast FL, early this morning, as a mid level short wave trough passes overhead. Trending warmer today, less breezy and with less persistent cloud cover for most as high temperatures near 60 across inland southeast GA to the upper 60s toward north-central FL. Coastal locales will top out in the upper 50s across the Golden Isles to low 60s along the First Coast. More sunshine across southeast GA and the Suwannee River Valley today compared to yesterday, but mostly to partly cloudy skies will linger along the coast and across northeast generally south of I-10 corridor. Cloudiness increases from the south and west overnight as a broad surface forms offshore of the FL Atlantic coast as a longer wave mid/upper level trough deepens across the western Gulf. Low temperatures will trend warmer tonight compared to this morning and range by 15-20 degrees across the local area from the upper 30s across far inland southeast GA north and west of Waycross to the mid 50s toward Flagler Beach. A few light showers and sprinkles will also be possible overnight mainly across northeast Florida as the surface low that develops near the southeast FL Atlantic coast tracks northward, east of the local area, into early Wednesday morning. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... On Wednesday, an upper shortwave will pass over the area as it traverses a deepening longwave trough over the eastern US. This will bring isolated to scattered showers to the area. Limited moisture will keep rainfall amounts light and won`t bring much relief to the severe drought. Around seasonable temperatures under mostly cloudy skies expected on Wednesday with highs in the upper 50s to mid 60s. An arctic cold front will pass through Wednesday night bringing another round of showers before shifting into central FL by Thursday morning. Much colder and drier air filters into the area in the wake of the front as high pressure builds in from the northwest. Despite mostly sunny skies, temperatures will struggle under the brisk northwest winds and strong cold air advection. Afternoon temperatures will only reach into the upper 40s in inland SE GA to the upper 50s in north-central FL. High pressure builds overhead allowing winds to calm by Friday morning. Arctic air, calming winds, and clear skies will allow for a hard freeze to develop over inland areas Thursday night as lows fall into the low 20s over SE GA and mid 20s over inland NE FL with a light freeze appearing more likely over downtown Jacksonville to the Jax Beaches where lows will fall to the upper 20s to the low 30s. Cold Weather Advisory conditions will be possible for NE FL with temperatures/wind chills in the low/mid 20s. && .LONG TERM /FRIDAY THROUGH MONDAY/... Friday, high pressure remains over the area maintaining dry conditions. Another cold night under mostly clear skies will allow lows to fall to low/mid 30s over inland SE GA and portions of inland NE FL west of the St Johns river. Another trough will dive south and east to the Gulf coast this weekend with another cold front moving through the area Sunday. Not expecting much moisture or showers ahead of the front with partly cloudy skies and southwest winds Saturday becoming mostly sunny and winds northwesterly Sunday with another potential freeze downtown and potential hard freeze over inland SE GA Sunday night. && .AVIATION /12Z TUESDAY THROUGH 12Z WEDNESDAY/... MVFR restrictions will linger near SSI briefly this morning and advertised TEMPO restrictions through 14z. Elsewhere, VFR with cloud bases 4-6 kft. Still anticipate further ceiling base rise through 12- 15z as the gradient between the high to the WNW and the low level coastal trough offshore of the local coast weakens. Gusty NNE to NNW winds at the coast will also relax into the afternoon. Weakening surface high pressure builds across the terminals this evening from the Gulf Coast states as NNW to WNW winds subside below 6 kts. Multi- layered cloudiness increases tonight with the approach of the next surface front. After 06z, low stratus may cause restrictions mainly across FL terminals as a trough axis begins to lift northward from south FL ahead of the approaching cold front. Less than a 20% chance of showers near SGJ 06-12z. && .MARINE... Elevated northerly winds across the local waters will gradually weaken through today as a coastal trough breaks down and shifts farther offshore as high pressure builds across the the Gulf coast states. The high will extend across the local waters tonight into Wednesday as a broad surface low tracks northward well east of the local Atlantic coast. Westerly winds increase Wednesday night as a strong cold front moves across the region. Small craft advisory conditions return Thursday trailing the frontal passage and continue into Thursday night. Winds and seas subside Friday as high pressure builds directly over the local waters. The high will shift southeast Saturday as a weaker, dry cold front moves across the waters with a surge in northwest to north winds behind the frontal passage late Saturday into Sunday. Rip Currents: Moderate rip current risk today for southeast GA and northeast FL beaches with lingering longshore currents. Low risk Wednesday under offshore flow. && .FIRE WEATHER... -Areas of low dispersions Tuesday -High dispersions Thursday High pressure over the southeast US will sink southward into the Gulf today. Weak surface and transport winds will create low daytime dispersions today. Lingering dry airmass will create MinRH values of 22-27 percent over inland Georgia northwest of US84. On Wednesday, west-southwest winds increase ahead of an approaching front resulting in good dispersions. Light scattered showers will move through the area Wednesday into Wednesday night. Breezy northwesterly winds develop in the wake of the front bringing high dispersions area-wide on Thursday. A cold and dry airmass filters in for the end of the work week lowering RHs into the 20s. Elevated Fire Danger will be possible for inland southeast Georgia on Thursday due to breezy winds and low RHs. FOG POTENTIAL AND OTHER REMARKS: Significant fog is not expected this morning or Tonight. Freeze and frost are expected for inland SE GA this morning.

Reintroduced rain/snow mentions inland along the cold front Thursday morning, although wintry precip impacts are still not expected. Small craft advisories issued Tuesday night to Thursday for coastal waters from Oregon Inlet to Cape Lookout && .KEY MESSAGES... 1) Cold temperatures this morning with a gradual warming trend today into Wednesday 2) A low pressure system and cold front Wednesday through Thursday night will bring the next chance of rain, with a slight chance of non-accumulating snow 3) Generally dry cold front moves through early Sunday, with another surge of cold, dry air behind it MARINE: SCA conditions Wednesday and Thursday, with gale force winds possible Thursday night. SCA conditions possible again for the weekend. && .DISCUSSION... KEY MESSAGE 1... High pressure centered over the region has allowed for good radiational cooling conditions this morning with light/calm winds and clear skies. Lows expected in the mid to upper 20s inland to 30s along the coast around sunrise. Some inland locations have even dropped into the lower 20s. NBM temps are too warm in this scenario and followed closely to MOS guidance with manual adjustments for the peak radiational cooling locales. High pressure slides offshore today with southwest winds bringing a warming trend with temps climbing to near 60 today and tomorrow afternoon, which is a few degrees above climatology. KEY MESSAGE 2... A robust northern stream trough digs into the eastern CONUS today through Wednesday. An embedded shortwave moving across the Deep South will bring improved upper level forcing and expect an area of low pressure to develop off the Southeast coast Wednesday which will pass off the NC coast Wednesday evening. There continues to be some uncertainty with the exact track of the low offshore which will ultimately determine precip coverage and amounts across the region. The best precip chances will be along OBX and areas offshore where we continue likely PoPs, which tapers to slight chance well inland. Guidance is not that impressive with precip amounts which shows around a quarter of an inch along the coast to little accumulation inland. All liquid precip expected through Wednesday night. A second shortwave moves through the upper trough Wednesday night with an attendant cold front pushing across ENC early Thursday morning. ENC is removed from best upper level dynamics but sufficient moisture remains that we could see a rain/snow mix inland with frontal forcing becoming all rain closer to the coast along the front, but rain amounts expected to be limited, only up to a tenth of an inch at best. Any snow mixed in is not expected to accumulate, and no wintry precip impacts are expected. Strong CAA develops behind the front later Thursday morning but it appears this will be a typical cold air chasing the moisture, likely keeping us dry Thursday afternoon. For this reason, stepped down from NBM chance snow to slight chance, with room to step down even further. The upper level trough axis pushes across the region Thursday evening bringing descent forcing but by this time moisture will be limited. However, coastal locations could see a brief period of rain/snow. Guidance has been trending drier and NBM probs are less than 25% for any accumulation precipitation, for either rain or snow. KEY MESSAGE 3... A deep upper level trough with an associated cold front is expected to move through the region early Sunday. There isn`t much moisture to play with ahead of this front, so precip chance is on the lower side (PoPs 15-20%). NBM called for snow chances, but with sfc temps in the 40-45F range at that time, paired with the drier trend, elected to stick with all rain for the forecast. Behind the front, below average temps and dry conditions return. && .AVIATION /09Z TUESDAY THROUGH SATURDAY/... VFR conditions are forecast through the entire period as high pressure builds in from the southwest. Sct high clouds continue to stream in from the SW but offer little in the way of impact to the area. We also remain too dry for fog development. Otherwise, light and variable to calm winds tonight become SW`rly at about 5-10 kts with gusts up around 10-15 kts by mid morning. These winds will persist into Tue evening before winds become light and variable once again Tue night. Skies remain partly cloudy through the period. Outlook: Pred VFR flight cats expected through much of the period with high pressure in control. While there is still uncertainty, a low pressure system Wednesday and Thursday could bring precip, lower ceilings, and gusty winds with it. && .MARINE... High pressure has settled across the waters bringing W/SW winds around 5-15 kt becoming SW later as high moves offshore. Seas have also laid off, around 2ft across all coastal waters. Tonight, winds begin to pick up as a low crosses the great lakes and high pressure sits offshore, tightening the pressure gradient. This will bring gusts around 25kts for the warmer gulf stream waters tonight. Issued a SCA for gulf stream waters given 6Z guidance increased confidence in SCA gusts. For now have SCA going until Friday 00Z, at which point gale force gust chances increase. Winds briefly lessen to 15-20 knots Wednesday morning for 3-6 hours before picking back up to 20-30 knots as a low forms offshore and strengthens. Again, best chance of seeing small craft gusts with this low is along warmer gulf stream waters with SW flow. Cooler inland sounds/rivers will see much lighter wind gusts with the SW winds thanks to a marine inversion. A cold front will push across the waters Thursday morning with strong CAA developing Thursday afternoon and Thursday night and could see NW winds bring strong SCA to Gale Force conditions across the waters. Conditions improve late in the week with high pressure briefly building into the area. This weekend, another cold front moves through, bringing elevated winds and seas once again. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None. MARINE...Small Craft Advisory from 7 PM this evening to 7 PM EST Thursday for AMZ152-154-156. && $$ |

There is the potential for slight chance of thunder Wednesday through Thursday, though, the better risk is across the marine area. -A strong cold front will move through the Keys on Thursday. This will bring a period of breezy to windy conditions to the Keys along with strong to potentially near gale breezes to the Florida Keys coastal waters. Small Craft Advisories are becoming increasingly likely later this week. -In the wake of the front, expect considerably cooler and drier conditions for late week through the weekend. && .DISCUSSION... Issued at 430 AM EST Tue Jan 13 2026 KBYX radar has remained active all night with the shower activity mostly across the Straits of Florida. However, occasionally a few showers have moved across the Upper Keys, especially near Key Largo. MRMS data over the last 3 hours show estimated rainfall amounts of a trace to a few hundredths of an inch of rainfall in association with these showers across the Upper Keys. The heaviest amounts remain across the central Straits where upwards of three tenths of inch were estimated due to heavier activity. GOES 19 Nighttime Microphysics shows partly cloudy skies across the Keys with the most robust cloud cover across the SE Gulf and the Straits of Florida. Temperatures along the Island Chain are in the lower 70s and dew points are in the upper 60s to near 70 degrees. An elongated surface ridge remains in place across the Southeast U.S. early this morning. This is promoting mainly northeast breezes of 10 to 15 knots at marine platforms surrounding the Island Chain. .FORECAST... The surface ridge currently across the Southeast U.S. will continue to drift southeastward through tonight while weakening. This will result in light to gentle breezes during the day becoming mainly light for tonight. High moisture for this time of the year remains in place across the Keys leading to chances PoPs for the next several forecast periods. The exception will be tonight when rain chances drop to slight due to a subtle dip in moisture. GOES 19 Total Precipitable Water (TPW) shows estimated PWATs of 1.3 to 1.5 inches across the Keys which is between the 75th and 90th percentile for the date. In addition, a pre-frontal trough will approach the Keys Wednesday/Wednesday night. Modest instability, plenty of moisture, and a trigger being the pre- frontal trough will yield the potential for a slight chance of a thunderstorm. The better risk for a thunderstorm will remain across the marine area where the greater instability, moisture, and lift will be. Latest statistical guidance has backed off on the idea of thunder across the area, however, confidence wasn`t high enough this update to remove it just yet. Most likely this will be scrutinized period by period. One of the other reasons for not removing just yet is that we will have some upper level forcing this go around which we typically don`t always see in the Keys. The main show arrives Thursday when a strong cold front will usher in Florida winter for the next several days and through the length of the extended. Temperatures and humidity are expected to tumble Thursday night. Overnight lows are expected to be 50 to 55 for Thursday night with daytime highs Friday only managing 60 to 65 degrees. The air conditioners will be able to get a well deserved break for late week through at least the middle of next week. Accompanying the frontal passage, expect a rapid surge in breezes across all the Florida Keys with breezy, becoming windy conditions anticipated along the Island Chain. For the marine area, the potential exists for a window of near gale breezes. The peak of the wind surge right now looks to be Thursday afternoon and evening before gradually slackening thereafter. Breezes will originally be westerly before shifting to the northwest to north overnight and then north by Friday morning. Breezes rapidly slacken by Friday afternoon as the gradient collapses. The cold front will push out any residual moisture resulting in a dry forecast from Thursday night through the extended. Another reinforcing front may press through the Keys sometime Sunday/Sunday night keeping the chill going. Daytime highs through the period will be near 70 degrees and overnight lows in the upper 50s to near 60 degrees. Dew points will also have a hard time reaching 60 degrees after the front passes through on Thursday. && .MARINE... Issued at 430 AM EST Tue Jan 13 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, a surface ridge stretching across the southeastern U.S. will weaken and slide southeastward through tonight. This will promote slackening breezes to light to gentle. Thereafter, a pre- frontal trough will slide across the region on Wednesday, briefly clocking winds around to the southeast initially, then southwest, and eventually west to northwest. This will be followed by a second, stronger cold front on Thursday with a round of strong to potentially near gale breezes. Small Craft Advisories are becoming increasingly likely later this week. && .AVIATION... (06Z TAFS) Issued at 430 AM EST Tue Jan 13 2026 Periodic MVFR CIGs may be observed at either island terminal this morning. This may also be accompanied by some rainfall with a chance of rain persisting into this afternoon. VCSH will likely be introduced as showers approach either terminal from the Straits starting with MTH. Near surface winds will be generally light and out of the north to northeast. && .CLIMATE... On this day in Keys Weather History, in 1981, the temperature dropped to 41F in Key West, which is the daily record and tied for the coldest temperature ever recorded in Key West.

| #1257048 (Received by flhurricane at: 4:09 AM 13.Jan.2026) AFDSJU Area Forecast Discussion National Weather Service San Juan PR 502 AM AST Tue Jan 13 2026 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, BEACH FORECAST... .KEY MESSAGES... Issued at 502 AM AST Tue Jan 13 2026 * Passing trade-wind showers continue: Brief showers will affect windward and coastal areas of Puerto Rico and the U.S. Virgin Islands, mainly during the morning and evening hours, with limited afternoon showers over western Puerto Rico. Periods of sunshine will continue between showers. * Localized flooding remains possible: While widespread flooding is not expected, increased moisture later in the week may cause ponding on roads and isolated urban or small stream flooding, especially across eastern Puerto Rico and the U.S. Virgin Islands. * Moderate rip current risk: life-threatening rip currents are expected along north and east-facing beaches of Puerto Rico and the U.S. Virgin Islands through the workweek. The risk may increase this weekend, becoming high due to stronger winds and a northwesterly swell. && .Short Term(Today through Thursday)... Issued at 502 AM AST Tue Jan 13 2026 Mainland Puerto Rico experienced calm weather overnight, while a trade wind disturbance brought passing showers to the U.S. Virgin Islands, with some reaching eastern Puerto Rico. Winds were from the east at 5 to 10 mph. Skies were mostly clear in mainland Puerto Rico, but partly to mostly cloudy in the U.S. Virgin Islands. Overnight temperatures ranged from the low 70s to the upper 60s along the coast and from the upper 50s to the low 60s in the interior valleys and mountains. Weather conditions across Puerto Rico and the U.S. Virgin Islands will remain influenced by a broad surface high pressure system extending from the central Atlantic into the Caribbean, along with a weak induced surface trough north of the region. This setup will maintain an east-northeasterly low-level wind flow, allowing shallow moisture confined mainly below 3 km to advect into the area and produce passing showers, particularly during the morning and evening hours. As the surface trough lifts out, winds will gradually veer to the east. This will allow modest moisture, with precipitable water values ranging between 1.3 and 1.5 inches, to continue filtering into the islands, supporting additional shower activity. However, a persistent mid-level ridge over the region will limit vertical development, resulting in a typical trade-wind pattern characterized by brief showers affecting coastal and windward areas during the morning and evening hours, followed by limited afternoon convection mainly across western Puerto Rico. On Wednesday, low-level winds are expected to veer further as the surface pattern responds to a frontal boundary exiting the eastern United States. This change will favor a slight increase in tropical moisture and cloudiness, with shower activity becoming more noticeable in the afternoon. Temperatures are expected to remain near seasonal values. By Thursday, a deep-layer mid- to upper-level trough will move further eastward of the Lesser Antilles, while a mid-level ridge continues to dominate the northeastern Caribbean. Under this pattern, trade-wind showers will persist across the region as a surge of moisture increases Precipitable Water to 1.5 to 1.75 inches. Enhanced by low-level convergence and local orographic effects, this could lead to ponding of water on roads and in poorly drained areas, particularly across eastern Puerto Rico and the U.S. Virgin Islands, occasionally throughout the day. Overall, a limited risk of flooding is expected, though isolated instances of urban and small stream flooding cannot be ruled out on any given day. Residents and visitors are encouraged to stay informed by following the latest forecasts and updates in case conditions change. && .Long Term(Friday through Tuesday)... Issued at 502 AM AST Tue Jan 13 2026 On Friday, model guidance indicates that a frontal boundary will remain north of the region, while a pre-frontal trough may enhance low-level moisture convergence and atmospheric instability, supporting a wetter pattern. Friday currently appears to have the greatest rainfall potential, with a limited flood risk mainly across western Puerto Rico during the afternoon hours. Isolated thunderstorms cannot be ruled out. Precipitable water values are forecast to range between 1.4 and 1.9 inches from Friday through Saturday, near to above climatological normals for this time of year. Low-level winds will generally remain from the east to southeast at 10 to 15 mph on Friday, then shift to the east to northeast by Friday night into Saturday while increasing to 15 to 20 mph with gusts up to 25 to 30 mph. Breezy to locally windy conditions are expected Saturday and early Sunday, which may lead to loose outdoor items being blown around, especially across exposed and coastal areas. From Sunday through Tuesday, precipitable water values are expected to decrease to between 1.2 and 1.5 inches, with patches of near-average moisture moving across the region. This will support more variable but seasonable conditions, with passing trade wind showers and limited convective development each afternoon. No flooding concerns at this time. A subtropical jet streak near 250 mb will establish a favorable dynamic pattern from Tuesday night into Wednesday, supporting upper-level divergence and an induced surface trough. As a result, an increase in the frequency of showers is expected across the forecast area under a northeasterly low-level wind flow. Continue to monitor the forecast updates. Temperature-wise, ensemble guidance continues to indicate near seasonal to above-normal temperatures across Puerto Rico and the U.S. Virgin Islands throughout the long-term period. && .AVIATION... (06Z TAFS) Issued at 502 AM AST Tue Jan 13 2026 Expect VFR conds today. SHRA/SHRA may occasionally affect TJSJ, TIST, and TISX, with brief MVFR conds possible near TJPS in the afternoon (16-22z). Similar conditions with less activity are likely for Wednesday. Winds will remain light and variable overnight, shifting to ENEE at 10 to 15 knots after 13z, with higher gusts and sea breeze variations. && .MARINE... Issued at 502 AM AST Tue Jan 13 2026 A surface high pressure across the central Atlantic and a surface trough to the north of the region will maintain gentle to moderate east to northeast winds through mid-week, then shifting from the east to southeast by Thursday. This pattern will support passing trade- wind showers, mainly across the Atlantic waters, with occasional showers also moving through the Caribbean passages. By Saturday, strengthening east to northeast winds and the arrival of a long-period northerly swell will likely result in choppy to rough seas, leading to hazardous marine conditions during the weekend. Mariners are advised to continue monitoring the forecast. && .BEACH FORECAST... Issued at 502 AM AST Tue Jan 13 2026 A moderate risk of rip currents continues today along the northern and eastern beaches of Puerto Rico, as well as Culebra and St. Croix, with breaking waves around 4 feet. Similar conditions are expected to persist through most of the workweek. A moderate risk means that life-threatening rip currents are possible within the surf zone, and beachgoers should exercise caution at all times. Conditions are likely to deteriorate over the weekend as winds increase and a long-period northerly swell arrives. This may lead to a return of a high risk of rip currents across Atlantic exposed beaches of Puerto Rico and the U.S. Virgin Islands.

Reintroduced rain/snow mentions inland along the cold front Thursday morning, although wintry precip impacts are still not expected. && .KEY MESSAGES... 1) Cold temperatures this morning with a gradual warming trend today into Wednesday 2) A low pressure system and cold front Wednesday through Thursday night will bring the next chance of rain, with a slight chance of non-accumulating snow 3) Generally dry cold front moves through early Sunday, with another surge of cold, dry air behind it MARINE: SCA conditions possible Wednesday and Thursday, with gale force winds possible Thursday night. SCA conditions possible again for the weekend. && .DISCUSSION... KEY MESSAGE 1... High pressure centered over the region has allowed for good radiational cooling conditions this morning with light/calm winds and clear skies. Lows expected in the mid to upper 20s inland to 30s along the coast around sunrise. Some inland locations have even dropped into the lower 20s. NBM temps are too warm in this scenario and followed closely to MOS guidance with manual adjustments for the peak radiational cooling locales. High pressure slides offshore today with southwest winds bringing a warming trend with temps climbing to near 60 today and tomorrow afternoon, which is a few degrees above climatology. KEY MESSAGE 2... A robust northern stream trough digs into the eastern CONUS today through Wednesday. An embedded shortwave moving across the Deep South will bring improved upper level forcing and expect an area of low pressure to develop off the Southeast coast Wednesday which will pass off the NC coast Wednesday evening. There continues to be some uncertainty with the exact track of the low offshore which will ultimately determine precip coverage and amounts across the region. The best precip chances will be along OBX and areas offshore where we continue likely PoPs, which tapers to slight chance well inland. Guidance is not that impressive with precip amounts which shows around a quarter of an inch along the coast to little accumulation inland. All liquid precip expected through Wednesday night. A second shortwave moves through the upper trough Wednesday night with an attendant cold front pushing across ENC early Thursday morning. ENC is removed from best upper level dynamics but sufficient moisture remains that we could see a rain/snow mix inland with frontal forcing becoming all rain closer to the coast along the front, but rain amounts expected to be limited, only up to a tenth of an inch at best. Any snow mixed in is not expected to accumulate, and no wintry precip impacts are expected. Strong CAA develops behind the front later Thursday morning but it appears this will be a typical cold air chasing the moisture, likely keeping us dry Thursday afternoon. For this reason, stepped down from NBM chance snow to slight chance, with room to step down even further. The upper level trough axis pushes across the region Thursday evening bringing descent forcing but by this time moisture will be limited. However, coastal locations could see a brief period of rain/snow. Guidance has been trending drier and NBM probs are less than 25% for any accumulation precipitation, for either rain or snow. KEY MESSAGE 3... A deep upper level trough with an associated cold front is expected to move through the region early Sunday. There isn`t much moisture to play with ahead of this front, so precip chance is on the lower side (PoPs 15-20%). NBM called for snow chances, but with sfc temps in the 40-45F range at that time, paired with the drier trend, elected to stick with all rain for the forecast. Behind the front, below average temps and dry conditions return. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... VFR conditions are forecast through the entire period as high pressure builds in from the southwest. Sct high clouds continue to stream in from the SW but offer little in the way of impact to the area. We also remain too dry for fog development. Otherwise, light and variable to calm winds tonight become SW`rly at about 5-10 kts with gusts up around 10-15 kts by mid morning. These winds will persist into Tue evening before winds become light and variable once again Tue night. Skies remain partly cloudy through the period. Outlook: Pred VFR flight cats expected through much of the period with high pressure in control. While there is still uncertainty, a low pressure system Wednesday and Thursday could bring precip, lower ceilings, and gusty winds with it. && .MARINE... High pressure has settled across the waters bringing W/SW winds around 5-15 kt becoming SW later as high moves offshore. Seas have also laid off, around 2ft across all coastal waters. Tonight, winds begin to pick up as a low crosses the great lakes and high pressure sits offshore, tightening the pressure gradient. This will bring gusts around 25kts for the warmer gulf stream waters tonight. Given the lower confidence of seeing frequent 25+ kt gusts, elected to not issue a small craft advisory at this time despite being 24 hours away. 6Z guidance may provide more clarity on the setup and be the decision maker. Winds briefly lessen to 15-20 knots Wednesday morning before picking back up as a low forms offshore and strengthens. Again, best chance of seeing small craft gusts with this low is along warmer gulf stream waters with SW flow. Cooler inland sounds/rivers will see much lighter wind gusts with the SW winds thanks to a marine inversion. A cold front will push across the waters Thursday morning with strong CAA developing Thursday afternoon and Thursday night and could see NW winds bring strong SCA to Gale Force conditions across the waters. Conditions improve late in the week with high pressure briefly building into the area. This weekend, another cold front moves through, bringing elevated winds and seas once again. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None. MARINE...None. && $$ |

Issued at 320 AM EST Tue Jan 13 2026 - A couple degrees warmer today with isolated showers, mainly Cape Canaveral southward - Strong cold front arrives Wednesday night into Thursday morning, bringing a brief increase in rain chances - Below normal temperatures Thursday onward; sub-freezing morning lows and frigid wind chills in the 20s to 30s, especially Friday morning and next Monday morning && .DISCUSSION... Issued at 320 AM EST Tue Jan 13 2026 Today-Tonight...An inverted surface trough remains just offshore this morning while a low cloud deck persists over the northern half of the area. The most recent cold front to move through ECFL has settled across the Florida Straits as a stationary front. Current temperatures range widely from the low/mid 50s north of Orlando to the upper 60s along the Treasure Coast. Where moisture remains marginally sufficient today, mainly over the Treasure Coast and Gulf Stream, isolated showers will be possible. That said, a majority of the area will stay dry with temperatures warming a few degrees more compared to yesterday (highs in the low/mid 70s). Moisture return and the south Florida front moving north helps to expand 20-30% rain chances northward overnight, but the majority of activity will be focused out over the Gulf Stream. In other words, a continuation of isolated showers will simply expand north toward Cape Canaveral and even the Volusia Coast through daybreak Wednesday. Lows tonight are forecast to settle into the mid 50s north to the low/mid 60s from the Orlando metro to the Treasure Coast. Wednesday-Thursday...Wednesday morning, a weak cool front looks to be draped across portions of the Treasure Coast and Gulf Stream waters, before sliding east of the area by midday. Our focus is on the next series of cold fronts, approaching central Florida late Wednesday night into Thursday morning. 500mb height falls begin in earnest late Wednesday afternoon as a trough deepens over the eastern U.S. Rain chances look limited Wednesday, with one batch of QPF shifting well offshore and models in disagreement on very light QPF north of Orlando in the afternoon. We will be waiting on the arrival of a stronger cold front early Thursday, bringing with it slightly better rain chances (30-55%). Model guidance lends to a little lower confidence than is typical at this time range. GFS+AI ensembles point to generally 0.2" or less of measurable rain between now and the FROPA Thursday morning, whereas the ECMWF+AI ensembles are more centered around 0.3"-0.4" of rain. Granted, a couple tenths of rain is not a huge difference with most of the area under D0-D1 (abnormally dry to moderate drought) conditions. As quickly as rain moves in, it will move out over the open Atlantic Thursday afternoon. A westerly breeze Wednesday under a mostly cloudy sky is likely to keep temperatures a bit cooler, especially north of I-4. Behind Thursday`s front, noticeably colder and drier will rush southward supported by a 10-15+ mph wind (gusting 20-25 mph at times, especially at the coast). Highs in the upper 60s to mid 70s Wednesday trend down on Thursday, struggling to reach the 60-degree mark Orlando northward. Skies quickly clear Thursday night, setting the stage for a cold night and brisk wind chill values. Friday-Monday...Before stepping outside for work or school Friday morning, be sure to dress warmly! Forecast morning lows have not changed much from the previous cycle, maintaining the idea of temperatures at or below freezing along and north of I-4, in addition to sub-freezing lows across interior ECFL as far south as Lake Okeechobee. Making it feel even colder will be a northwest breeze, sending wind chill values into the mid/upper 20s for a majority of the area. As a result, a Cold Weather Advisory will be needed for a large portion of ECFL Friday morning. Winds decrease through the day Friday into early Saturday as high pressure builds over the peninsula. Despite plenty of sun Friday afternoon, temperatures will really struggle to get out of the 50s from Osceola/northern Brevard and points north (low 60s south). Mostly clear conditions Friday night sets the stage for another cold night (30s-mid 40s). With lighter winds overnight, there is a possibility of frost developing Saturday morning over portions of the area. Daytime temperatures make a comeback, climbing into the 60s to low 70s. But then... Below normal temperatures look to be reinforced by another cold front Saturday night into Sunday. A lack of moisture along this front is keeping rain chances out of the forecast. Temperatures swing colder again Sunday into early next week, with lows in the 30s to mid 40s and highs only in the 50s and 60s. Sub-freezing temps are possible again, especially Monday morning. Behind the front, northwest winds will again add a wind chill factor with values falling into the mid 20s to low 30s Monday morning. && .MARINE... Issued at 320 AM EST Tue Jan 13 2026 Weak surface trough remains over the nearshore waters through tonight as N-E winds decrease today. Isolated showers are forecast along the Treasure Coast and over the Gulf Stream, expanding north and eastward in time, especially on Wednesday. Seas fall to 3-4 ft today and 2-4 ft Wednesday. A strong cold front approaches early Thursday morning, quickly pushing south of the waters by the afternoon. Shower chances increase to 40-60%, followed by freshening NW winds behind the front. Poor to hazardous boating conditions gradually expand from the offshore waters Thursday morning to the remaining marine legs Thursday afternoon. NW winds 20-25 kt with gusts around 30 kt (esp. offshore) build seas to 4-7 ft nearshore and 6-9 ft offshore Thursday night. The pressure gradient quickly unwinds Friday as high pressure builds overhead, allowing seas to fall to 3-6 ft Friday afternoon. Favorable boating conditions return Friday night and continue through much of Saturday (seas 2-3 ft). && .AVIATION... (06Z TAFs) Issued at 1251 AM EST Tue Jan 13 2026 MVFR and IFR CIGs continue to build southward across the area. Have continued prevailing MVFR/IFR CIGs across the interior and DAB. Guidance is not consistent on how long this will persist. For now, have maintained lower CIGs lingering through 08Z. But wil continue to monitor. VFR conditions are then forecast once these lower CIGs lift.

No significant changes have been made to the forecast. Some interior rain showers very late tonight, but any snow showers confined to the very highest terrain. Relatively mild temperatures today and especially Wednesday with sharply colder weather arriving later Thursday into Friday behind a strong cold front. While a significant storm appears unlikely Saturday night into Sunday...but a bit of snow is certainly possible. && .KEY MESSAGES... - Overall quiet weather today, followed by a period of showers late tonight across interior southern New England with some snow showers confined to the very highest terrain. - Mild weather Wed into Wed night with a few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. Highs Wed in the 40s to near 50. - Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. - Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. && .DISCUSSION... KEY MESSAGE 1...Overall quiet weather today, followed by a period of showers late tonight across interior southern New England with some snow showers confined to the very highest terrain. A series of shortwaves quickly move from west to east tonight along zonal flow. First disturbance passes with little impacts outside of an increase in mid and high level clouds this morning across northern MA. Milder day follows as a transient ridge axis develops over New England. Latest guidance still shows a milder day on tap as 925mb temps climb to 0- 2C. A more amplified shortwave digs over the Great Lakes later Tuesday into Tuesday night. First sign of its approach will be increasing mid and high level clouds later today. Should see a broken band of precipitation pass through the CWA with the higher POPs located across northern Massachusetts. Much of the forcing with this shortwave will be confined to Northern New England and so shower activity will be limited in coverage and intensity. May also see a few flakes mix in across the higher terrain but accumulations if any will be light with marginal temperatures and modest QPF. KEY MESSAGE 2...Mild weather Wed into Wed night with a few rain showers perhaps ending as a brief period of light snow showers early Thu across the interior. Highs Wed in the 40s to near 50. An amplifying shortwave trough moves across the Great Lakes and into northern New England Wed into early Thu. Out ahead of this cold front/amplifying shortwave trough...southerly flow will result in unseasonably mild temperatures. Despite considerable clouds...high temps will be well into the 40s to near 50 in a few spots. These readings are a solid 10+ degrees above normal for mid January standards. Given the bulk of the dynamics passing to our north...not expecting a lot of precipitation and much of this time will feature dry weather. Nonetheless...a few showers will be possible at times Wed into Wed night with the focus for them across interior southern New England closer to the shortwave energy. As colder air begins to work in from the west...may see precipitation end as a brief period of light snow showers across interior southern New England early Thu morning. Any snow accumulations should be a dusting to generally less than 1 inch. KEY MESSAGE 3...Turning colder Thu with falling daytime temps. Dry & cold Thu night-Fri. Lows Thu night in the upper single digits & teens with highs Fri mainly in the upper 20s and lower 30s. Low pressure will rapidly intensifies Thu into Thu night as it tracks northeast from northern new England into the Canadian Maritimes. The result will be a shot of much colder air working into southern new England Thu into Fri. Temps on Thu will likely fall during the afternoon into the upper 20s and 30s on a stiff gusty west wind. Low temps Thu night will drop into the upper single digits and teens. Wind chills will drop to between 5 below and 10 above by daybreak Fri. High temps on Fri will only recover into the upper 20s and lower 30s. High pressure building in from the west will keep our weather dry...despite the cold temperatures. KEY MESSAGE 4...Milder high temps into the 40s Sat with perhaps a bit of snow sometime Sat night-Sun...but a significant storm is unlikely. High pressure quickly moves east of the mid-Atlantic coast to start the weekend as another trough gets carved out across the Great Lakes. This allows for a quick rebound in temperatures with highs mainly in the 40s on Sat. The forecast then becomes quite complex Sat night into Sunday with an amplifying trough to our west with several pieces of shortwave energy. The problem is that the guidance is struggling on which piece of energy to amplify and where the actual surface low develops. Latest guidance tends to develop the main surface low too far north and late for a significant storm. That being said...there are a few pieces of guidance including the CMC/ICON that have a wave of low pressure further south with the potential for an inverted trough setup. So while a significant storm appears unlikely...given the amount of shortwave energy to our west we can not rule out period of snow sometime Sat night into Sun if an inverted trough sets up. Whether or not this happens remains to be seen...but it is something to watch in the coming days. && .AVIATION /07Z TUESDAY THROUGH SATURDAY/... Forecaster Confidence Levels...

Updated at 300 AM EST Tue Jan 13 2026 - Occasional showers continue today favoring east coast metro areas. - Hazardous winds and seas in the Atlantic will improve today. - Another strong cold front could drop across the peninsula on Thursday, bringing reinforcing cold air and more increased rain chances. && .SHORT TERM... (Today through Wednesday) Issued at 300 AM EST Tue Jan 13 2026 Latest ensembles and global model solutions show a decaying sfc boundary lingering over SoFlo today, and maybe lifting a little northward. This will require keeping some POPs through early this evening, 20-30 percent, favoring the eastern side of SoFlo. 00Z MFL sounding and model data keep PWATs in the 1.3-1.5" range, for which potential for isolated rainfall amounts of 1" still remains in the forecast. By Wednesday, models show a mid lvl shortwave feature moving around the base of a deepening trough over the SE CONUS. Both systems are shown migrating eastward, with overall synoptic flow veering more southwestward/westward by the afternoon hours. This will further focus highest chances of rain over the Atlantic coastline and around the Broward/Palm Beach metro areas. Meanwhile, a more robust sfc cold front will be pushed southward towards northern Florida by late Wednesday. High temperatures for the short term should remain in the upper 70s to near 80, with overnight lows tonight mainly in the low 60s, with some mid 60s around the east coast metro areas. && .LONG TERM... (Wednesday night through Monday) Issued at 300 AM EST Tue Jan 13 2026 Model consensus depict a FROPA reaching the area on Thursday, with rain chances increasing in the Wed night-Thu morning time frame ahead of the front. Latest timing with this feature places the best chances of showers during the mid/late morning hours on Thursday with scattered to numerous showers possible. In general, dynamic support seem to remain poor as the parent trough/low complex will continue to pull NE into the eastern seaboard. And with prevailing cloud cover, the daytime heating component should remain weak enough to keep mention of thunderstorms out of the forecast attm. This, however, will continue to be revised and updated as necessary. 50-70 POPs remain in the forecast for Thursday morning. Winds veer northward Thursday night into Friday as broad high pressure spreads across the SE CONUS, triggering another cold/dry air advection event. Coldest temperatures with this robust cold air mass are expected Friday morning before sunrise, with coastal areas dropping into the upper 30s to mid 40s, and interior/northern areas in the low-mid 30s. Friday afternoon will also remain fairly cool for being SoFlo, with highs struggling to hit the mid-upper 60s. Temperatures then gradually warm up during the weekend, but still remaining around the low 70s in general. Then by Monday, models seem to suggest another possible cool down with a front approaching the area. There is still a lot of uncertainty in long range guidance, so the forecast philosophy beyond the weekend will continue to be updated with new guidance. && .AVIATION... (06Z TAFS) Issued at 124 AM EST Tue Jan 13 2026 Periods of SHRA continue throughout the day mainly for the Atlantic terminals. Prevailing NE winds around 10kt expected after 15Z, along with possible periods of MVFR CIGs. && .MARINE...

| #1257043 (Received by flhurricane at: 3:06 AM 13.Jan.2026) AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 257 AM EST Tue Jan 13 2026 .WHAT HAS CHANGED... Model trends continue to favor a more progressive (faster) and drier solution for the late week system. This translates to a lower chance for accumulating winter precipitation Thursday morning. && .KEY MESSAGES... 1) Remaining dry, while trending breezy and milder today and Wednesday. 2) Low pressure develops along an approaching cold front Wed night, and passes by to the N/NE of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of light snow Thursday morning. 3) Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. && .DISCUSSION... As of 255 AM EST Tuesday... KEY MESSAGE 1...Remaining dry and trending breezy and milder today and Wednesday. Strong sfc high pressure (~1030mb) is centered over the Gulf coast, ridging ENE into the local area will build south across the southeast today, as low pressure over central Canada remains well north of the local area. SSW return flow becomes a bit stronger today, allowing for highs to warm up quickly into the 50s under a mainly sunny sky. A few readings around 60 degrees are possible across south central VA and NE NC. A few clouds cross the area tonight and early Wednesday ahead of the cold front associated with the northern stream system, but otherwise mainly clear and not as cold tonight with lows in the 30s. Despite some increasing mid to high clouds Wednesday, mild return flow will provide highs well into the 50s west of the bay again on Wednesday (low to mid 50s Lower Eastern Shore), with highs near 60 degrees far SE counties. KEY MESSAGE 2...Low pressure develops along an approaching cold front Wed night, and passes by N of the area on Thursday. Some light precipitation is possible late Wednesday night, potentially ending as a brief period of light snow Thursday morning. 00z/13 models continue to advance a faster, drier solution for the late week system. A potent northern stream shortwave will dig south from the Ohio Valley into the northern mid- Atlantic late Wednesday through Thursday, as a dampening southern stream shortwave traverses the Gulf coast. Our area will be in between these features, with the resultant subsidence allowing for rapid drying and therefore lower QPF. There is still a chance for some light overrunning moisture to cross the area, along and (mainly) behind the crossing cold front Wed night. Precipitation will mainly fall in the form of light rain showers. While the faster arrival of colder air would allow for a changeover to snow showers as precipitation tapers off early Thursday morning, it is increasingly apparent that the colder air will be chasing the departing moisture, with the developing surface low crossing near of just south of the Mason-Dixon line as it exits to the NNE. This is a pattern that rarely results in any tangible snowfall across most of our region. For its part, the latest NBM remains a bit higher than latest model consensus, likely still at least in part reflecting the previous model consensus of this past weekend. Would therefore not be surprised to see these chances drop off completely as we get closer. Thus, while some light snow is possible before precipitation tapers off, have removed any snow accumulations from the digital database and expect very limited to no impacts from snow with this system. KEY MESSAGE 3...Turning colder, with below normal temperatures expected from Thursday night into early next week. Mainly dry throughout the period, though there is a low-end chance for some light precipitation both Saturday and Sunday. Becoming rather cold and breezy/windy in strong cold advection in the wake of the Arctic frontal passage Thursday. Look for highs to struggle to get out of the 30s N and in the 40s S, even w/ diminishing cloud cover. Cold w/ lows in the teens and 20s Thu night. Even as winds diminish, wind chills in the teens are expected Friday morning. Not quite cold enough for Cold Weather Advisories but close, and certainly a stark contrast from the warmer temperatures expected today and tomorrow. The rest of the extended period will primarily feature below normal temperatures and mainly dry conditions. An upper level ridge persists across the west coast of North America, keeping an upper level trough in place from central Canada into the SE CONUS, with resultant NW flow allowing for another influx of Arctic air in the wake of a second, reinforcing Arctic frontal passage over the weekend. Guidance is still keying in on a pair of weak disturbances, one ahead of and one just behind that next strong cold frontal passage. At this point, the "best" chance for any precipitation looks to be on Sunday, though PoPs remain low at only 15-20%. The overall pattern still appears too progressive to tap into any southern stream moisture, reinforcing the developing cold, dry pattern. Another round of cold temperatures follows behind that front for Sunday night through early next week, with highs in the 30s and lows in the teens to low 20s. && .AVIATION /07Z TUESDAY THROUGH SATURDAY/... As of 1145 PM EST Monday... VFR conditions currently across area terminals will prevail through the 06Z/13 TAF period. Light W-SW winds average 5-7 kt overnight under a mainly clear sky. Expect SW winds to increase a bit on Tuesday late morning, gusting to 15-20 kt by afternoon. Outlook: Dry/VFR conditions are expected across the mid-Atlantic through midweek. Increasing low-level wind shear is expected ahead of an approaching cold front late Tuesday evening into Wed morning. The front will cross the region Wed evening, with some light rain possible behind the front late Wed night into Thursday morning. A brief period of sub-VFR conditions will be possible early Thu morning, as a secondary front crosses the region, ushering in a much colder airmass for the late week period. && .MARINE... As of 220 AM EST Tuesday... Key Messages: - SCA conditions expected tonight due to gusty SW winds. - A series of cold fronts will cross the region late this week with strong SCA conditions possible Thursday into Friday. High pressure is situated south of the waters this morning. SW winds are generally 10-15 kt with occasional gusts to 20 kt, but these winds will subside later this morning into this afternoon. The aforementioned high translates offshore by this evening as strong low pressure advances through SE Canada, tightening the pressure gradient over the area. In addition, a SW low-level jet still looks to overspread the waters tonight into Wednesday morning. Southerly flow picks up again this afternoon but should remain sub-SCA until ~00z/7 PM this evening. After 00z, winds become SW and increase to 15-20 kt on the Chesapeake Bay with some potential for 20-25 kt sustained winds on the coastal waters N of Parramore Island. Gusts up to 25-30 kt are also expected. Small Craft Advisories have been issued for the Chesapeake Bay and coastal waters N of Cape Charles through mid-morning Wednesday. Sub-SCA SW flow should then prevail later Wednesday into the first part of Wednesday night. A strong cold front is then expected to swing through the region early Thursday morning as low pressure develops over New England. This front will bring an abrupt wind shift to the NW, along with a substantial increase in the wind speeds to 20-25 kt for most of the waters. These elevated winds likely persist into Thursday night as cold air advection maximizes. An additional round of Small Craft Advisories are very likely during this period. While forecasted gusts currently fall just shy of Gale-force, cannot rule this out on the ocean and will continue to monitor over the next few forecast cycles. Winds quickly subside around sunrise Friday morning before elevated SW flow potentially returns Friday night/Saturday morning ahead of another cold front. The current model consensus pushes this front through overnight Saturday and additional SCA headlines are probable as winds become NW. Seas are 2-3.5 ft this morning, with 1-2 ft waves in the bay. Seas and waves increase to 3-5 ft and 2-3 ft, respectively, tonight through Wednesday morning. Elevated seas and waves return early Thursday morning and continue into Thursday night in the wake of the cold front. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.

Issued at 228 AM EST Tue Jan 13 2026 - Below normal temperatures are expected for several days behind a strong cold front on Wednesday. Friday morning will be the coldest this week with a medium to high chance (60-80 percent) of an inland hard freeze (25F or lower). - Hazardous marine conditions will develop behind the next cold front on Wednesday night and Thursday with a medium to high chance (60-80 percent) of gale force northwest wind gusts west of Apalachicola. && .SHORT TERM... (Today and Tonight) Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis across the area today will lead to mostly clear to partly cloudy skies with just some passing high cloud cover. Afternoon highs will generally range from the upper 50s to mid 60s with overnight lows ranging from the mid 30s to mid 40s. && .LONG TERM... (Wednesday through Monday) Issued at 228 AM EST Tue Jan 13 2026 Two reinforcing cold frontal passages are expected. The first one will arrive starting late Wednesday, and the second one will arrive on Saturday or Saturday night. There will probably be some scattered light showers in advance of the front on Wednesday, but moisture will be limited with both fronts. Any rain that occurs will be on the light side. Breezy conditions are likely on Thursday behind the first front with peak gusts in the 25-35 mph range. The main impact to the local area will be cold temperatures. There is a medium to high chance of a hard freeze (25F or lower) for inland areas on Friday morning. Additional light freezes are expected for portions of the area each morning thereafter into early next week. Despite all the cold temperatures, there is currently no wintry precip expected in our area. && .AVIATION... (06Z TAFS) Issued at 1207 AM EST Tue Jan 13 2026 Surface high pressure ridge axis gradually moves south of the terminals on Tuesday. Light and variable winds become north on Tuesday with a tendency to become more westerly at DHN and ECP during the afternoon. With the weak pressure gradient in place, winds generally AOB 5 kts. VFR conditions w/SCT cirrus becoming BKN late Tuesday. && .MARINE... Issued at 228 AM EST Tue Jan 13 2026 A high pressure ridge axis will move south directly across the waters by this evening, bringing a continued decrease in wind. Once high pressure moves further south on Wednesday, westerly breezes will freshen in advance of a strong reinforcing cold frontal passage on Wednesday night. Northwesterly gusts near gale force will follow that front on Thursday with the strongest winds west of Apalachicola. Winds will quickly decrease on Thursday night and Friday as a high center passes directly across the waters Friday evening. Yet another cold front will cross the waters on Saturday evening. && .FIRE WEATHER... Issued at 228 AM EST Tue Jan 13 2026 The high pressure center at the heart of the existing dry air mass will pass directly across the districts today. This will result in a combination of places with critically low humidity below 25 percent and low daytime dispersion due to the lack of wind and low mixing heights. On Wednesday, dispersion will increase markedly with higher values resulting from development of gusty southwest winds in advance of a strong reinforcing cold frontal passage late Wednesday. Strong gusty northerly winds will follow that front on Thursday, supporting another day of high dispersion. && .HYDROLOGY... Issued at 228 AM EST Tue Jan 13 2026 No flooding is expected for at least the next 7 days. Any rain that falls in the next week will not be hydrologically significant.

Issued at 233 AM EST Tue Jan 13 2026 The front that pushed through on Sunday is still lingering just south of Florida. This front will lift slightly north today allowing for some extra cloud cover over the area. A shower or two will also be possible in SW Florida. By Wednesday we will see a much stronger cold front heading our way. This front will push through Wednesday Night bringing scattered showers as it passes by. Colder air will start to filter in behind the front with highs north of I-4 staying below 60 degrees. Our coldest morning so far this season will be on Friday. For our inland areas we could see freezing temperatures as far south as Hardee and Desoto Counties with the Nature Coast getting into the mid to upper 20`s. Highs on Friday will stay in the 50`s for almost all of us except SW Florida which could touch 60 degrees for an hour or two in the afternoon. We will slightly warmer temperatures on Saturday before another cold front slides through on Sunday morning. We won`t be seeing any rain with this front but it will bring temperatures back down into the 30`s for most of us Monday morning. Highs on Monday will once again be stuck in the 50`s north of I-4 with the low 60`s everywhere else. && .AVIATION... (06Z TAFS) Issued at 233 AM EST Tue Jan 13 2026 We will be seeing a lower cloud deck throughout the TAF period for most of the period however this cloud deck looks to primary stay between 3,500 and 5,000 feet. This will allow for mainly VFR conditions but cant rule out an occasional drop to MVFR CIGS. Winds will remain out of the north through the period. && .MARINE... Issued at 233 AM EST Tue Jan 13 2026 Winds will remain out of the north for Tuesday and Wednesday with speeds around 10 knots. We will see a strong cold front slide through Wednesday night that will bring some scattered showers and isolated thunderstorms to the Gulf. Behind it winds will increase quickly peaking at 20 to 25 knots by Thursday afternoon. Winds will not remain that high for long as high pressure starts to move overhead. This will start to decrease the winds late Thursday night and by Friday afternoon should only be around 5 knots. Winds will shift more easterly as the high pressure moves away on Saturday between 5 to 10 knots. && .FIRE WEATHER... Issued at 233 AM EST Tue Jan 13 2026 We will see dry and cooler conditions for our Tuesday and the early part of Wednesday. A strong cold front will push through the area Wednesday night bringing scattered showers to the area. Behind the front we will see breezy conditions on Thursday with gust to 20 to 25 mph. Drier air will filter in Thursday night creating critical RHs by Friday afternoon but winds will have calmed down by then.

Winds and seas will remain below SCA thresholds, around 10-15 kt and 1-3 ft, through the day Tuesday. Then, with the approaching low pressure system and decreased high pressure, a strong LLJ around 40-50 kt will increase the winds and seas Tuesday night into Wednesday morning. Confidence has increased in SCA conditions with SW winds increasing to 15-20 kt with gusts to 25 kt in the Ches. Bay and coastal waters north of Cape Charles. The southern coastal waters will likely see lower wind speeds at 10-15 kt. Local wind probs show 70-90% probs of sustained 18 kt gusts in the middle bay, with 40-50% probs in the lower bay and mouth of the bay. In the northern coastal waters, probs have increased to 50-80% probs of 25 kt gusts. Additionally, seas and waves will increase to 3-5 ft north of Cape Charles (2-3 ft south) and 2-4 ft in the Ches. Bay (highest waves in the middle bay). After collaboration with neighboring offices, have held off on issuing SCA at this time, but will likely need issuing in the next package if trends remain. Then on Wednesday, a dry cold front will gradually cross the local area by Thursday morning, with a stronger secondary front moving through the area during the day Thursday. SW winds on Wednesday will to be NW behind the fronts, increasing during the day Thursday to likely SCA conditions. The surge of strong CAA may be slightly lagged, impacting the area Thursday night, which would allow winds to increase again. Local wind probs have decreased slightly for gale forced gusts Thursday night, now at 30-50% for the coastal waters. Will continue to monitor the trends with future forecasts. Another series of cold fronts may impact the local waters this weekend. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None. MARINE...None. && $$ |
| #1257037 (Received by flhurricane at: 1:33 AM 13.Jan.2026) AFDCHS Area Forecast Discussion National Weather Service Charleston SC 131 AM EST Tue Jan 13 2026 .WHAT HAS CHANGED... The first key message was updated to mention only this afternoon for low relative humidity values. For the second key message, wind gusts should remain within Small Craft Advisory levels Thursday into Thursday evening. The risk for Gale force wind gusts has diminished. && .KEY MESSAGES... 1) Dry high pressure will remain across southeast Georgia and South Carolina today, yielding low relative humidity values this afternoon. 2) Dangerous fire weather and marine conditions possible as gusty winds and low humidity values arrive behind a mostly dry cold front Thursday into Friday. 3) Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. && .DISCUSSION... KEY MESSAGE 1: Dry high pressure will remain across southeast Georgia and South Carolina today, yielding low relative humidity values this afternoon. Dry sfc high pressure will linger across the Southeast U.S. today. Forecast soundings indicate that mixing will range between 2.5 to 3 kft this afternoon. As mixing begins, sfc dewpoints should remain in the 20s through mid-day. However, weak southwest winds may result in a slow increase in dewpoints from south and near the coast, increasing into the 30s. Minimum RH values should occur during the early afternoon hours, before the dewpoint recovery. Min RH values are forecast to range from the mid 20s inland to the mid 30s along the coast. High temperatures are forecast to range around 10 degrees warmer than values reached on Monday, generally in the low 60s. KEY MESSAGE 2: Dangerous fire weather and marine conditions possible as gusty winds and low humidity values arrive behind a mostly dry cold front Thursday into Friday. On Thursday a rex block will be established over the Western United States allowing for a long wave trough axis to amplify across the Eastern United States. In the mid-levels of the atmosphere, a closed mid-level low will be moving east across the Great Lakes with a strong push of lower heights approaching the area from the west (120 m height falls in 12 hrs). This magnitude of DCVA/ height falls is rather impressive, but precipitation chances are limited (<15%) with the surface cold front Thursday morning/ afternoon. There are several reasons for this. The main reason being the Wednesday wave. This wave will be moving away early Thursday with the LFQ of the subtropical jet streak moving off of the coast. During this type of setup, most of the precipitation gets going off of the South Carolina/ North Carolina coast. Behind the surface cold front, strong low level CAA will take hold with 850 mb temperatures dropping from 0 degrees C to -8 degrees C. This, in combination with peak mixing and downslope flow in the low and mid levels, will likely result in wind gusts Thursday afternoon on the higher end of the guidance envelope, with 25 to 30 mph gusts likely, with some gusts to 35 mph possible over land. A Lake Wind Advisory will likely be necessary with probabilities of reaching 25 kt around 55%. Additionally, dewpoints will rapidly fall behind the cold front allowing relative humidity values to approach 25%. It should be noted that the Wambaw and Glissons Pond RAWS sites have both had fuel moisture values in the single digits Sunday and Monday afternoons. Surface high pressure will settle overhead Friday, with dewpoints likely mixing out to near the single digits in the afternoon. The latest LREF probabilities show a 50 - 70% chance of RH values less than 25% away from the immediate coast. Winds will be much weaker Friday though given the proximity of the surface high pressure to coastal South Carolina and Georgia. KEY MESSAGE 3: Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. Surface high pressure now looks to move east faster, or allow winds to decouple quicker Thursday night/ Friday morning. As such, low temperatures will likely be in the upper teens for areas of rural Georgia away from the coast (and closer to the surface high pressure), and low 20s for the rest of coastal South Carolina. Right at the beaches (including the Charleston Peninsula), expect lows in the upper 20s. Wind Chill to temperature spread will likely be greatest Thursday evening, with the differential becoming less and less as winds slacken by Friday morning. Still though, enough wind is forecast that a Cold Weather Advisory might be required for some of the area Friday morning. Rural Georgia has ~ a 60- 80% chance of needing a Cold Weather Advisory, while coastal South Carolina and Georgia has ~ a 20- 50% chance of needing a Cold Weather Advisory. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... VFR conditions will prevail at CHS/JZI/SAV terminals through 06Z Wednesday. Extended Aviation Outlook: VFR conditions will continue for KCHS, KJZI and KSAV through late week. NW winds could gust to around 20 kts in the wake of cold front. && .MARINE... Broad high pressure will remain across the marine zones today and tonight. The pattern should yield around 5 kts of wind today, gradually increasing to 5 to 10 kts tonight. Seas are forecast to remain between 2 to 3 ft. Wednesday, the marine zones will remain between a developing low pressure system over the Gulf Stream and a cold front over the western Carolinas. A weak gradient on the west side of the low keeps benign marine conditions in place despite increased shower chances. A strong cold front will cross the area Wednesday night. Northwest winds should develop in the wake of the front, with gusts around 25 kts across the Atlantic waters of GA and SC on Thursday into Thursday evening. As a result, wave heights will build during the daylight hours on Thursday, peaking between 3-5 ft across the nearshore with 6ft beyond 30 NM Thursday evening. Small Craft Advisories will likely be needed for all marine zones outside the CHS Harbor Thursday and Thursday evening. The center of a large area of high pressure will arrive on Friday, supporting winds around 10 kts with 1-2 ft seas. Winds should gradually strengthen as a dry cold front sweeps across the region on Saturday, with gusty winds and building seas, possibly reaching Small Craft Conditions across a portion of the waters. && .CHS WATCHES/WARNINGS/ADVISORIES...

| #1257038 (Received by flhurricane at: 1:33 AM 13.Jan.2026) AFDMFL Area Forecast Discussion National Weather Service Miami FL 127 AM EST Tue Jan 13 2026 ...New AVIATION... .KEY MESSAGES... Updated at 124 AM EST Tue Jan 13 2026 - Occasional showers today especially across the east coast metro. - Hazardous winds and seas in the Atlantic and Gulf waters today. - Another strong cold front could drop across the peninsula late this week, bringing reinforcing cold air and more increased rain chances. && .UPDATE... Issued at 1234 PM EST Mon Jan 12 2026 The frontal boundary has worked its way through the area and is now stalling over the Florida Straits. This boundary will help to keep some chances for showers later today, tonight and tomorrow. Showers are expected to be light and should not strengthen into storms as the atmosphere is too stable with dry air aloft. High temperatures are expected in the upper 70s today across the region. && .SHORT TERM... (Tonight through Tuesday) Issued at 1154 PM EST Sun Jan 11 2026 The cold front continues to work its way southwards through South Florida and slowly wash out through the morning hours on Monday. This boundary will provide a lifting mechanism that will be enough to spark some rain showers across the region (mainly the southern half of the area and east coast metro) late tonight and through Monday morning. Even with some shower development, accumulations are not expected to cause any concerns with the latest forecast highlighting no more than than 0.3-0.5" of rain across South Florida. Highest accumulations are expected across the east coast metro with little to no rain for the Gulf coast since winds shifting to out of the northeast will create some coastal convergence effects along the east coast. Either way, no impactful rainfall is expected and any amount will help alleviate at least a little of the ongoing drought. There will be an uptick in winds as well through the morning hours, but likely not gusting to more than 15-20 mph. Heading towards the mid-week period, the frontal boundary is expected to stall out over the Florida Straits and there won`t be a strong enough push of drier air into South Florida as the front loses its strength. Thus, slight chances for a few showers will continue on Tuesday, although again any accumulation will be low. High temperatures for the next couple of days are expected in the upper 70s to near 80, with overnight lows Tuesday morning expected in the upper 50s to low 60s for SW Florida and the low to mid 60s for the east coast metro. && .LONG TERM... (Tuesday night through next Sunday) Issued at 1154 PM EST Sun Jan 11 2026 The front will remain stalled out over the Florida Straits through the entire mid-week period, with its presence helping keep isolated chances for showers in place across the local Atlantic waters and the east coast through Wednesday. Moving forward into the late week period, the pattern starts to undergo some much bigger changes. Ensemble guidance shows synoptic- scale troughing amplifying across the Eastern Seaboard by the end of the week as meridional jet-stream flow occurs over the Great Plains states. This trough has potential to cover almost the entire Eastern Seaboard from Maine down to Central Florida. As this trough amplifies, near-surface flow in South Florida will shift to a southwesterly direction on Wednesday, which will increase warm air advection and moisture advection over the area for shower development (PWATs around 1.5"). By Thursday and into Thursday night, the attendant cold front from the trough will rush southwards and cause an increase in rain chances again on Thursday with PoPs around 40% before a much colder and drier air mass settles in behind the front on Thursday night. This front could drop temps late Thursday night into the 30s and 40s across the region. Even with this more active weather pattern, impacts from rainfall are not expected so the primary item to monitor will be the colder temperatures. High temperatures across the region on Friday may not reach 70 due to this colder air. The forecast becomes less certain heading into the weekend, but conditions are expected to be much calmer for Friday and Saturday as a more stable/zonal pattern and the abundantly dry air mass settle in. Beyond that, guidance hints at another front possibility for the Sun-Mon time frame, but this is highly uncertain given that it is at the very end of the forecast period. && .AVIATION... (06Z TAFS) Issued at 124 AM EST Tue Jan 13 2026 Periods of SHRA continue throughout the day mainly for the Atlantic terminals. Prevailing NE winds around 10kt expected after 15Z, along with possible periods of MVFR CIGs. && .MARINE... Issued at 1234 PM EST Mon Jan 12 2026 Conditions improve this afternoon in the wake of the front, but lingering hazardous conditions are still possible through this afternoon with seas up to 7 feet. Quieter conditions are then expected through mid-week, although some isolated to scattered showers will remain possible. && .BEACHES... Issued at 1154 PM EST Sun Jan 11 2026 A strong northerly wind surge will promote a high risk of rip currents across the Atlantic coastline today. This high risk is likely to last into mid-week as winds shift to an east-northeast direction. && .PRELIMINARY POINT TEMPS/POPS...

For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Several Freeze Events through Early Next Week - Hard Freeze Inland & Coastal Freeze Likely Friday morning. Wind chills in the 20s Friday morning - Cold Weather Advisory potential for portions of northeast FL. - Consecutive Nights of Inland Freezes from Fri Night through next Tue Night. - Small Craft Advisory conditions Thursday & Thursday night. Potential for gale force gusts. && .NEAR TERM /THROUGH TONIGHT/... Low level cloudiness and elevated northerly winds near the coast will gradually decrease this morning as a coastal trough over the local Atlantic waters edges farther east. A few sprinkles will be possible, mainly across northeast FL, early this morning, as a mid level short wave trough passes overhead. Trending warmer today, less breezy and with less persistent cloud cover for most as high temperatures near 60 across inland southeast GA to the upper 60s toward north-central FL. Coastal locales will top out in the upper 50s across the Golden Isles to low 60s along the First Coast. More sunshine across southeast GA and the Suwannee River Valley today compared to yesterday, but mostly to partly cloudy skies will linger along the coast and across northeast generally south of I-10 corridor. Cloudiness increases from the south and west overnight as a broad surface forms offshore of the FL Atlantic coast as a longer wave mid/upper level trough deepens across the western Gulf. Low temperatures will trend warmer tonight compared to this morning and range by 15-20 degrees across the local area from the upper 30s across far inland southeast GA north and west of Waycross to the mid 50s toward Flagler Beach. A few light showers and sprinkles will also be possible overnight mainly across northeast Florida as the surface low that develops near the southeast FL Atlantic coast tracks northward, east of the local area, into early Wednesday morning. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... On Wednesday, an upper shortwave will pass over the area as it traverses a deepening longwave trough over the eastern US. This will bring isolated to scattered showers to the area. Limited moisture will keep rainfall amounts light and won`t bring much relief to the severe drought. Around seasonable temperatures under mostly cloudy skies expected on Wednesday with highs in the upper 50s to mid 60s. An arctic cold front will pass through Wednesday night bringing another round of showers before shifting into central FL by Thursday morning. Much colder and drier air filters into the area in the wake of the front as high pressure builds in from the northwest. Despite mostly sunny skies, temperatures will struggle under the brisk northwest winds and strong cold air advection. Afternoon temperatures will only reach into the upper 40s in inland SE GA to the upper 50s in north-central FL. High pressure builds overhead allowing winds to calm by Friday morning. Arctic air, calming winds, and clear skies will allow for a hard freeze to develop over inland areas Thursday night as lows fall into the low 20s over SE GA and mid 20s over inland NE FL with a light freeze appearing more likely over downtown Jacksonville to the Jax Beaches where lows will fall to the upper 20s to the low 30s. Cold Weather Advisory conditions will be possible for NE FL with temperatures/wind chills in the low/mid 20s. && .LONG TERM /FRIDAY THROUGH MONDAY/... Friday, high pressure remains over the area maintaining dry conditions. Another cold night under mostly clear skies will allow lows to fall to low/mid 30s over inland SE GA and portions of inland NE FL west of the St Johns river. Another trough will dive south and east to the Gulf coast this weekend with another cold front moving through the area Sunday. Not expecting much moisture or showers ahead of the front with partly cloudy skies and southwest winds Saturday becoming mostly sunny and winds northwesterly Sunday with another potential freeze downtown and potential hard freeze over inland SE GA Sunday night. && .AVIATION /06Z TUESDAY THROUGH 06Z WEDNESDAY/... MVFR stratus deck will continue to impact the terminals over the next few hours at times, but the recent trend of bases starting to rise is expected to continue. Still anticipate further ceiling base rise through 12-15z as the gradient between the high to the WNW and the low level coastal trough offshore of the local coast weakens. Gusty NNE to NNW winds at the coast will also relax into the afternoon. Weakening surface high pressure builds across the terminals this evening from the Gulf Coast states as NNW to WNW winds subside below 6 kts. Multi-layered cloudiness increases tonight with the approach of the next surface front. After 06z, low stratus may cause restrictions mainly across FL terminals as a trough axis begins to lift northward from south FL ahead of the approaching cold front. Less than a 20% chance of showers near SGJ 06-12z. && .MARINE... Elevated northerly winds across the local waters will gradually weaken through today as a coastal trough breaks down and shifts farther offshore as high pressure builds across the the Gulf coast states. The high will extend across the local waters tonight into Wednesday as a broad surface low tracks northward well east of the local Atlantic coast. Westerly winds increase Wednesday night as a strong cold front moves across the region. Small craft advisory conditions return Thursday trailing the frontal passage and continue into Thursday night. Winds and seas subside Friday as high pressure builds directly over the local waters. The high will shift southeast Saturday as a weaker, dry cold front moves across the waters with a surge in northwest to north winds behind the frontal passage late Saturday into Sunday. Rip Currents: Moderate rip current risk today for southeast GA and northeast FL beaches with lingering longshore currents. Low risk Wednesday under offshore flow. && .FIRE WEATHER... -Areas of low dispersions Tuesday -High dispersions Thursday High pressure over the southeast US will sink southward into the Gulf today. Weak surface and transport winds will create low daytime dispersions today. Lingering dry airmass will create MinRH values of 22-27 percent over inland Georgia northwest of US84. On Wednesday, west-southwest winds increase ahead of an approaching front resulting in good dispersions. Light scattered showers will move through the area Wednesday into Wednesday night. Breezy northwesterly winds develop in the wake of the front bringing high dispersions area-wide on Thursday. A cold and dry airmass filters in for the end of the work week lowering RHs into the 20s. Elevated Fire Danger will be possible for inland southeast Georgia on Thursday due to breezy winds and low RHs. FOG POTENTIAL AND OTHER REMARKS: Significant fog is not expected this morning or Tonight. Freeze and frost are expected for inland SE GA this morning.

Updated at 1206 AM CST Tue Jan 13 2026 - Low to medium (20-50%) rain chances today, ending from west to east - Wind chill values in the 30s area-wide Thursday and Friday mornings && .DISCUSSION... Issued at 1206 AM CST Tue Jan 13 2026 Low to medium (20-50%) chances of rain will continue through this afternoon as a mid-level low moves west to east. As the low moves off to the east late this afternoon into tonight, a cold front will bring drier air back to South Texas. The dry air will persist Wednesday through the end of the work week. Morning lows will be chilly Thursday and Friday with wind chills in the mid to upper 30s expected. Otherwise, generally quiet weather is expected with some sunshine finally returning by the middle of the week. Another cold front will swing through Friday night into Saturday. Most locations will stay dry with this upcoming front, though some showers are possible across the waters and maybe along the immediate coast. && .AVIATION... (06Z TAFS) Issued at 1206 AM CST Tue Jan 13 2026 VFR conditions will prevail through the TAF cycle. A few showers will continue to move across South Texas through this afternoon from west to east. Have continued a mention of showers for LRD and COT through 14Z-16Z. Expect showers will be possible later for ALI and VCT so added a TEMPO in from 16Z-20Z. A few light showers are also possible for CRP this afternoon as well, but have left this out of the TAF due to low confidence. && .MARINE... Issued at 1206 AM CST Tue Jan 13 2026 A gentle to moderate (BF 3-4) breeze will continue through Wednesday. Winds will increase again to fresh to strong (BF 5-6) Wednesday night into Thursday as another cold front moves across the waters, leading to Small Craft Advisory conditions. Winds will diminish to gentle to moderate (BF 3-4) once again Thursday night. There is a low (15-20%) chance of showers through this afternoon, with another low (less than 20%) chance Saturday as another front approaches the waters. && .FIRE WEATHER... Issued at 1257 PM CST Mon Jan 12 2026 Fire weather conditions are not expected today as relative humidity values remain above 40%. A front will usher in drier air (minimum relative humidity values less than 30%) for Wednesday through the end of the week which, when combined with ERC values in the 50th to 74th percentile, could lead to elevated fire weather conditions through the end of the work week.

Issued at 314 PM EST Mon Jan 12 2026 - Strong, gusty north winds producing windy conditions and hazardous boating conditions along the Volusia and north Brevard coasts will decrease this evening - Rain chances increase areawide Wednesday into Thursday ahead of the next cold front but amounts look limited - Sharply colder air Thursday night with a wind chill; Freezing temperatures possible north of Orlando Friday morning && .DISCUSSION... Issued at 314 PM EST Mon Jan 12 2026 Thru tonight...Inverted coastal trough developed just offshore the Volusia coast with strong and gusty north winds along the coast and a large area of low-based stratocu clouds that spread SW into Lake/Seminole counties. After sunset, the NE winds along the Space and Treasure coasts will back and all areas will become uniformly north with speeds decreasing even along the Volusia coast. Isolated showers over the Atlc may reach the Treasure coast but most areas will remain dry. Quite a range of overnight lows, from the lower 50s across Lake/interior Volusia to the mid 60s along the immediate Treasure coast. Tue-Wed (modified)...The old front now stationary to our south will begin to lift back to the north along with an increase in moisture overspreading southern sections with PWATs rising up to 1.50". This should produce isolated showers over the southern and coastal sections. Elsewhere over the north interior, conditions will remain mostly dry on Tuesday. Max temperatures recover a bit more, reaching the low to mid 70s. Attention turns to a mid level shortwave rounding the base of a deepening trough by midweek, as the features both progress toward the southeast U.S. That sfc front lifts a little further north on Wednesday, preceding a series of cold fronts advancing toward FL. This old boundary, along with additional forcing arriving from the north, will combine with 1.4-1.5" PW to raise rain chances to 25-40% Wednesday afternoon. The highest coverage of rain and timing remains a bit uncertain, but following the consensus of guidance, rain chances climb to 40-55% Wed night into Thu morning. Mostly cloudy conditions Wed are likely to keep temperatures a bit cooler (mid to upper 60s north, mid 70s south). Thu-Mon (modified)...A strong cold front is forecast to sweep across the area Thu, accompanied by breezy to gusty northwest winds (20-30 mph gusts) which will advect much drier air with clearing skies Thu afternoon and night. The combination of NW wind, clear sky conditions, and cold continental airmass will send temperatures plummeting into the 30s for most by Friday morning. Wind chill values in the mid to upper 20s are forecast Friday morning as well, solidly reaching Cold Weather Advisory criteria for most of ECFL with the possible exception of coastal Martin county. Sub-freezing temperatures (29F-32F) are possible Fri morning across north Lake and Volusia counties. Despite full sunshine Friday, max temps will range from the mid 50s Orlando north to the low 60s Martin county, 10-15 degrees below normal. Saturday promises another cold start with temperatures in the 30s and 40s, but a lighter wind makes for less of a wind chill factor but increases the risk of frost esp interior sections. Afternoon highs Sat rebound into the mid and upper 60s with lower 70s south. High pressure that built over Florida and the southeastern U.S. Friday/early Saturday will break down again Saturday afternoon as another cold front brings reinforcing cold air Sunday into Monday. There are discrepancies in models at this range regarding timing and any chance of precip, but for now, this forecast calls for a dry frontal passage. Temperatures trend colder Sunday into early next week behind this front, perhaps flirting with wind chills near the 30-degree mark again Monday morning. On the whole, expect a cooler-than-normal pattern to persist through the extended range with limited opportunities for measurable rainfall. && .MARINE... Issued at 314 PM EST Mon Jan 12 2026 Inverted coastal trough developed earlier today extending from near the Cape northward offshore NE FL. Tight north pressure gradient on the west side of this trough is producing sustained 20 knots with higher gusts over the nearshore Volusia waters so reissued the Small Craft Advisory there thru this eve. The NE pressure gradient on the east side of the trough axis supports NE winds 10-15 knots across the remainder of the Atlc coastal waters. With 7 FT seas subsiding, canceled the SCA for the Gulf Stream early and replaced with a Caution headline. Favorable boating conditions return Tuesday as NE winds decrease to 8-12 kt and seas reach 3-5 ft. Seas fall further to 2-4 ft Wednesday before offshore winds pick back up Wednesday afternoon and night (15- 20 kt). A strong cold front swings through Thursday, freshening northwest winds and building seas. Thus, poor to hazardous conditions quickly return Thursday morning to the offshore zones, expanding to the remainder of the local Atlantic waters Thursday afternoon into early Friday. Seas reach a peak of at least 7-9 ft Thursday night/early Friday, though this could be a conservative forecast (some guidance brings wave heights up to 10+ ft offshore). Rain chances increase ahead of and along the approaching cold front Wednesday into Thursday, and a lightning storm cannot be ruled out over the Gulf Stream. High pressure builds over the waters Friday and winds respond by decreasing and turning onshore. Seas, though, will take a bit longer to subside Friday afternoon esp over the Gulf Stream. Boating conditions look quite favorable Sat within a weak pressure gradient/light wind regime and seas 2 FT nearshore. && .AVIATION... (06Z TAFs) Issued at 1251 AM EST Tue Jan 13 2026 MVFR and IFR CIGs continue to build southward across the area. Have continued prevailing MVFR/IFR CIGs across the interior and DAB. Guidance is not consistent on how long this will persist. For now, have maintained lower CIGs lingering through 08Z. But wil continue to monitor.

Issued at 1145 PM CST Mon Jan 12 2026 - Cold temperatures are expected over the next 7 days. Sub- freezing temperatures are forecast across much of the area, especially Thursday night and over the weekend. - Strong northerly winds will occur over the marine area Wednesday night and Thursday, creating hazardous conditions for small craft. && .DISCUSSION... Issued at 1145 PM CST Mon Jan 12 2026 Another cool and dry day is expected for today as high pressure lingers across the area. This high will push southward into the Gulf and weaken as our next reinforcing cold front sweeps through the area Wednesday night. Looking aloft, a southern stream shortwave trough, located over western Texas will quickly approach the local area by tonight. Winds aloft will briefly turn southwesterly as it approaches. Although moisture return is still quite limited (PWATs remain below an inch), there may be enough forcing to squeeze out a few isolated to widely scattered showers as the trough passes overhead during the overnight hours. With the cold airmass still in place, expect a very light, overrunning rain. By the afternoon, longwave troughing diving southward from Canada will phase with the southern stream shortwave and push to our east by Wednesday night. This trough will help to send the aforementioned cold front through our area. Once again, a few light rain showers cannot be ruled out as the front pushes through. Behind it, another cold, dry airmass filters in from the north as high pressure builds in. Highs for today and Wednesday will be in the upper 50s to low 60s. Lows tonight will dip into the upper 30s to low 40s. After the front passes through Wednesday night, temperatures on Thursday will crash into the mid to upper 40s for highs and the low to mid 20s for lows Although winds Thursday night look to be rather light, apparent temperatures may get close to our Cold Weather Advisory criteria. We`ll keep an eye on this potential over the coming days. The second half of the period will be strikingly similar to the first half. By Friday and Saturday, highs will rebound to the upper 50s to low 60s, with lows Friday night ranging from the mid 30s inland to the low 40s along the coast. Another longwave trough is set to dig southward from Canada, helping to send yet another reinforcing cold front through our local area Saturday into Saturday night. Limited moisture return should keep PoPs low, although would not be surprised to see a few isolated showers pop up. After the front passes through temperatures drop once again, with highs Sunday and Monday in the upper 40s to low 50s and lows dropping into the 20s. A Low Risk of rip currents remains in place through much of the period, with a brief bump to Moderate expected Wednesday night for our western Florida Panhandle beaches. /96 && .AVIATION...

This westerly flow will increase on Wednesday ahead of the next cold front, followed by a moderate to strong offshore flow Wednesday night through Thursday in the wake of the front.

Forecast lows Thursday night have been adjusted colder, but wind chills are little changed. && .KEY MESSAGES... 1) Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. 2) Light rain is possible Wednesday as an upper level system moves overhead. 3) A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. && .DISCUSSION... KEY MESSAGE 1...Dry weather continues through tonight, with high temperatures reaching up to a degree or two above normal. Some good radiational cooling has occurred just past midnight, as temperatures continue to dip towards the 20s. Some cirrus that is streaming in from the west has thickened up over the last hour or so, which I believe has already started to hinder the cooling. May need to back off on some of the hourly temperature forecasts as we head through the rest of this morning. Elsewhere, quiet forecast still in store through tonight. A shortwave moves through late this morning, but doesn`t really do much at all to change the sensible weather. Plenty of sunshine on the way, with highs creeping up into the upper 50s to near 60. This will solidly be 10-12 degrees warmer than yesterday, about a degree or two above normal for mid-January. Southwesterly flow starts building in tonight ahead of the next disturbance. This causes low temperatures to be considerably warmer than the last couple of nights, generally in the mid-to-upper 30s inland, lower 40s at the coast.here. KEY MESSAGE 2...Light rain is possible Wednesday as an upper level system moves overhead. A southern stream shortwave will be pulled northeastward and across the Carolinas on Wednesday by a deep upper level trough developing across the Great Lakes. This shortwave will carry a slug of mid level moisture with it, visible on model 700 mb progs between 15z Wednesday and 00z Thursday. Isentropic analysis within the moisture-bearing layer shows only modest upglide, but still likely enough to produce light rain with less than 0.10 inches expected. Forecast PoPs have been tweaked higher to 40-50 percent along the coast centered on Wednesday afternoon. Very dry air between the mid level cloud base and the surface means there could be evaporational cooling as precipitation begins. I`ve kept Wednesday`s forecast highs near the NBM for now, but there`s certainly potential that highs will come in lower than is currently forecast if precipitation is more widespread or heavier in intensity. KEY MESSAGE 3...A pair of strong arctic cold fronts moving through Thursday morning and Saturday night will bring well below normal temperatures. Strong cold advection behind Thursday`s early morning arctic cold front will continue through the day and into Thursday night. Although yesterday morning`s models showed a decrease in wind speed late Thursday night, the new 00z models arriving now show this decrease in wind even more acutely. This should allow a radiational inversion to develop, especially inland, and we`ve accordingly pushed forecast lows down another couple of degrees. We`re now expecting lows in the upper teens with some lower 20s near the coast. This looks to be the second coldest arctic outbreak of the winter (so far) behind the December 15, 2025 event. In terms of public impact, lower forecast temperatures are being offset by lighter forecast winds. Forecast wind chill temperatures are still near the 15 degree threshold needed for a Cold Weather Advisory late Thursday night/Friday morning. Although model spread widens by the weekend, a second arctic cold front appears likely to arrive across the eastern Carolinas either Saturday night or Sunday morning. This will be followed by another shot of well below normal temperatures early next week. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... High confidence in VFR through the 06Z TAF period. Calm winds already in place at all terminals, which will continue for the next several hours. Light breeze at 5-7 kts out of the SSW builds in by 17-19Z this afternoon, decreasing slightly to 4-6 kts by sunset. Extended Outlook...VFR through perhaps midday Wednesday. Some restrictions are possible late Wednesday and Thursday. VFR returns Thursday night through Saturday. && .MARINE... Through Tonight...NNW winds around 5 kts back to the southwest by late this afternoon, increasing towards 10 kts by sunset. Winds veer slightly to the WSW overnight tonight, increasing more to 10-15 kts. Seas remain at 1-2 ft. Wednesday through Saturday Night...Breezy southwest winds as strong as 20-25 knots Wednesday night will precede a strong arctic cold front that will push off the North and South Carolina coastline early Thursday morning. Northwest winds behind the front on Thursday into Thursday night should average 20 to perhaps 25 knots. There is a good chance a Small Craft Advisory will be needed for the winds both ahead of and behind the cold front. High pressure building eastward along the Gulf Coast should lead to diminishing wind speeds Friday, however the high should push offshore Friday afternoon or evening with winds shifting southwesterly and increasing to 15-20 knots. Winds could increase further on Saturday when a second period of Small Craft Advisory conditions could occur ahead of the next front approaching from the west. && .ILM WATCHES/WARNINGS/ADVISORIES...

Chances are decreasing for wintry precipitation Thursday night. && .KEY MESSAGES... 1) Cold temperatures tonight with a gradual warming trend Tuesday into Wednesday 2) A low pressure system Wednesday through Thursday night will bring the next chance of rain, with some potential for a wintry mix or light snow as it moves offshore Thursday night MARINE: SCA conditions possible Wednesday and Thursday, with gale force winds possible Thursday night && .DISCUSSION... KEY MESSAGE 1... High pressure centered over the region will allow for good radiational cooling conditions tonight with light/calm winds and clear skies. Temps will fall quickly after sunset this evening with lows expected in the mid to upper 20s inland to 30s along the coast. Some inland locations may even drop into the lower 20s. NBM temps are too warm in this scenario and followed closely to MOS guidance. High pressure slides offshore Tuesday with southwest winds bringing a warming trend with temps climbing to the mid to upper 50s Tuesday and Wednesday afternoon, which is a few degrees above climatology. KEY MESSAGE 2... A robust northern stream trough digs into the eastern CONUS Tuesday through Wednesday. An embedded shortwave moving across the Deep South will bring improved upper level forcing and expect an area of low pressure to develop off the Southeast coast Wednesday which will pass off the NC coast Wednesday evening. There continues to be some uncertainty with the exact track of the low offshore which will ultimately determine precip coverage and amounts across the region. The best precip chances will be along the coast where we continue likely PoPs, which tapers to slight chance well inland. Guidance is not that impressive with precip amounts which shows around a quarter on an inch along the coast to little accumulation inland. All liquid precip expected through Wednesday night. A second shortwave moves through the upper trough Wednesday night with an attendant cold front pushing across ENC early Thursday morning. ENC is removed from best upper level dynamics but sufficient moisture remains that we could see a few showers across the region with frontal forcing, but rainfall amounts expected to be limited, only a few hundredths at best. Strong CAA develops behind the front Thursday morning but it appears this will be a typical cold air chasing the moisture with guidance keeping precip all liquid through Thursday afternoon. The upper level trough axis pushes across the region Thursday evening bringing descent forcing but by this time moisture will be limited. However, coastal locations could see a brief period of rain or show. Guidance has been trending drier and NBM probs are less than 25% for any accumulation precipitation, for either rain or snow. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... VFR conditions are forecast through the entire period as high pressure builds in from the southwest. Sct high clouds continue to stream in from the SW but offer little in the way of impact to the area. We also remain too dry for fog development. Otherwise, light and variable to calm winds tonight become SW`rly at about 5-10 kts with gusts up around 10-15 kts by mid morning. These winds will persist into Tue evening before winds become light and variable once again Tue night. Skies remain partly cloudy through the period. Outlook: Pred VFR flight cats expected through much of the period with high pressure in control. While there is still uncertainty, a low pressure system Wednesday and Thursday could bring precip, lower ceilings, and gusty winds with it. && .MARINE... High pressure has settled across the waters bringing light winds less than 10 kt, while seas have subsided to 3-5 ft. Have allowed the remaining SCA for the waters from Duck to Ocracoke inland to expire this morning. Light winds continues overnight, then becomes southwesterly around 5-15 kt Tuesday with seas around 2 ft. A low pressure system will pass off the coast Wednesday bringing increased winds and seas which may bring SCA conditions to the coastal waters south of Oregon Inlet, mainly where better mixing occurs near the warmer Gulf Stream waters. A cold front will push across the waters Thursday morning with strong CAA developing Thursday afternoon and Thursday night and could see NW winds bring strong SCA to Gale Force conditions across the waters. Conditions improve late in the week with high pressure briefly building into the area. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None. MARINE...None. && $$ |

Issued at 1207 AM EST Tue Jan 13 2026 - Below normal temperatures are expected for the next 7 days. Friday morning will be the coldest this week with a medium chance (30-60 percent) of an inland hard freeze. - Hazardous marine conditions will redevelop behind the next cold front on Wednesday night and Thursday, with northwest wind gusts at or near gale force. && .UPDATE... Issued at 748 PM EST Mon Jan 12 2026 No updates to the forecast this evening. Cloud cover continues to thin slowly. && .SHORT TERM... (This Evening through Tuesday) Issued at 222 PM EST Mon Jan 12 2026 A surface ridge axis extends this afternoon from northern Louisiana to northern Georgia. This axis will move southward and pass directly across the service area during the day on Tuesday. So as surface winds weaken and decouple tonight, we should have a decent setup for radiational cooling, especially later at night once we get rid of the existing cirrus deck. Most inland locations should get a light freeze and some frost. One thing that could disrupt the forecast of a light freeze is the OVC deck of stratocumulus clouds slow spreading inland from the JAX metro area. The NAM is quite bullish at bringing these clouds as far west as VLD and TLH. If that happens, it would cut off the radiational cooling in its tracks. The latest RAP is not nearly so bullish. && .LONG TERM... (Tuesday night through next Monday) Issued at 222 PM EST Mon Jan 12 2026 Two reinforcing cold fronts will cross the region in the Long Term. The first will pass the region on Wednesday PM. The second front will pass late Saturday or Saturday night. In both cases, moisture in the base of the eastern U.S. longwave trough will be limited, so precipitation, if any, will be light. On to the nitty gritty... The existing low-amplitude northern stream longwave will amplify dramatically on Wednesday, as the shortwave currently crossing the Canadian Rockies dives southeast and amplifies the longwave trough well to the south. This will drive a strong reinforcing cold front across our region on Wednesday evening. Meanwhile, the southern stream trough over northwest Mexico will accelerate east and deamplify as it moves east along the northern Gulf. This will support 20-40 PoPs during the day on Wednesday in advance of the front. Where it rains, QPF should be under 0.1 inches, which will have no long-lasting benefit. Gusty northerly winds behind the front on Thursday should bring gusts in the 25-35 mph range. At this point, it at least looks like winds should stay below Wind Advisory criteria. A widespread freeze is expected behind the front on Friday morning. Probabilities for a hard freeze (25 degrees or less) have decreased a little since yesterday. Those probs now range from around 30 percent along the I-10 corridor to 50-60 percent north of Dothan-Albany-Tifton. The incoming surface high will have already scooched east of I-75 by Friday afternoon. The next clipper-style reinforcing cold front will quickly sweep across the region around Saturday night, though there are notable timing differences in guidance. Once again, moisture will be lacking with this front, and NBM PoPs have decreased a little since yesterday, meaning more of the region with unmentionably low precip chances. If there is some light precip with this weekend`s front, then it could be a thin margin between the back edge of exiting precip and the arrival of sufficiently cold air for wintry precip. As mentioned yesterday, the vast majority of situations like this result in the incoming drier air winning out. In other words, the precip exits before the cold air arrives. Model hounds have surely sniffed out one or two model runs from recent days showing a small overlap between the precip and cold air north of the FL state line, most notably with last evening`s deterministic ECMWF run. However, this appeared to be an outlier solution in its bullishness. Indeed, the 12z ECMWF has arrived with a drier frontal passage. Today`s 12z GEFS plume diagrams show less than 10 percent of members with any wintry precip at DHN and ABY, with every one of those outliers showing barely more than a trace. All in all, wintry precip should not be expected. In the very low chance instance that it occurs, it would be brief, light, and low/no impact. This paragraph is intended to be "cold water" on any hype about wintry precip. && .AVIATION... (06Z TAFS) Issued at 1207 AM EST Tue Jan 13 2026 Surface high pressure ridge axis gradually moves south of the terminals on Tuesday. Light and variable winds become north on Tuesday with a tendancy to become more westerly at DHN and ECP during the afternoon. With the weak pressure gradient in place, winds generally AOB 5 kts. VFR conditions w/SCT cirrus becoming BKN late Tuesday. && .MARINE... Issued at 222 PM EST Mon Jan 12 2026 A high pressure ridge axis across extending this afternoon from northern Louisiana to northern Georgia will move south directly across the waters on Tuesday evening, bringing a continued decrease in wind. Once high pressure moves south on Wednesday, westerly breezes will freshen in advance of a strong reinforcing cold frontal passage on Wednesday night. Northwesterly gusts near gale force will follow that front on Thursday. Winds will quickly decrease on Thursday night and Friday as a high center passes directly across the waters Friday evening. Yet another cold front will cross the waters on Saturday evening. && .FIRE WEATHER... Issued at 222 PM EST Mon Jan 12 2026 The high pressure center at the heart of the existing dry air mass will pass directly across the districts on Tuesday. Tuesday will therefore feature an interesting combination of places with critically low humidity below 25 percent, along with low daytime dispersion due to the lack of wind and low mixing heights. On Wednesday, dispersion will increase markedly, with high values resulting from development of gusty southwest winds in advance of a strong reinforcing cold frontal passage late Wednesday. Strong gusty northerly winds will follow that front on Thursday, supporting another day of high dispersion. No fog is expected through Wednesday morning. Tuesday morning will start with areas of frost over many inland districts. && .HYDROLOGY... Issued at 222 PM EST Mon Jan 12 2026 No flooding is expected for at least the next 7 days.

Freezing temperatures are forecast to last several hours Tuesday morning moving above after sunrise. Residents should take action to protect sensitive vegetation and ensure outdoor pets have access to warm shelter. * According to the National Fire Protection Association, nearly half of all home fires occur between the months of December, January and February, with the increased risk attributed to the use of home heating devices such as portable space heaters and fireplaces. Those planning to use such devices during this cold snap should safety recommendations - such as using a screen and keeping a fire extinguisher near all fire places; and ensuring all space heaters are plugged directly into wall outlets and placed on level surfaces at least 3 ft from any flammable materials. && .SHORT TERM... (Tonight through Wednesday night) Issued at 753 PM CST Mon Jan 12 2026 A slow warming trend will start Tue but will only get into the low to mid 60s by Wed before dropping again to the low 30s north and low 40s south Wed night. This cold front will be able to produce some cloud cover and cloud depths enough to produce some light rainfall in a few locations. This is all it will be able to produce since cloud depth will not be anywhere close enough to produce lightning. Whatever rain it is able to produce will be fleeting mainly Tue night into early Wed. But there is a second chance of a few sprinkles as the secondary frontal sfc catches the first late Wed. This is when the surge of coolest air moves through. The air won`t be frigid but it will be cooler than where we are now. && .LONG TERM... (Thursday through Monday night) Issued at 753 PM CST Mon Jan 12 2026 We should only make it to around 50F for Thu. Then the coldest night for this system will be Thu night into Fri morning with lows in the upper 20s north to mid 30s south. It`s possible to reach the 60s as we warm up after this front but it won`t last long as another in a line of cold air dumps moves through by the weekend. This is the one that is most questionable at the moment and could go either way, wet and stormy or just a few showers moving through. The more detailed features with this won`t be deciphered until Thu at the earliest. We are pretty confident that this front will not take its time in moving through. We should see another warming trend after that as we move into the new week and yet another cold air surge from the north by Tue. This one is questionable to move through, and since it is so far out, there are no clues to if or when. But with the pattern as it is, we are fairly sure that another front moving toward the area in that time frame is a pretty good bet. && .AVIATION...

The risk for snow showers or squalls late afternoon and early evening has ended. The threat for an impactful coastal storm late in the week has diminished. && .KEY MESSAGES... - Overall quiet weather through Tue, then the chance of rain or snow showers Tue night - Unsettled mid to late week with periodic chances for showers && .DISCUSSION... KEY MESSAGE 1...Overall quiet weather through Tue, then the chance of rain or snow showers Tue night A couple fast moving northern stream shortwaves will be moving through New Eng through Tue night One shortwave moves through late tonight and early Tue. Moisture is limited and forcing for ascent is weak so only expecting an increase in cloud cover later tonight, mainly across northern MA. This shortwave will be followed by brief shortwave ridging on Tue which will bring sunshine and milder temps as a SW flow develops. 925 mb temps increase to 0 to +2C which supports highs Tue reaching into the mid 40s. A second stronger shortwave approaching from the Gt Lakes will bring increasing high clouds during the afternoon, then this shortwave lifts NE into northern New Eng and SE Canada Tue night. Moisture ahead of the shortwave is a bit more plentiful as PWATs increase to over 0.50" Tue night which may lead to some rain or elevation snow showers developing as a mid level front moves through. Guidance is indicating a band of showers accompanying the mid level front and deep moisture plume. But little to no impact expected with localized snow accum less than inch confined to the northern Berkshires. SW flow ahead of the shortwave will result in a milder night Tue night with lows in the low-mid 30s. KEY MESSAGE 2...Unsettled mid to late week with periodic chances for showers. Ensemble guidance continues to have good agreement in the overall synoptic pattern through the later part of this week. A deep trough moving into the Great Lakes by midweek progresses east into the northeast US and exiting heading into the weekend. Some smaller shortwaves may also move along this deepening trough`s flow and impact southern New England, leading to the chance for some light snow/rain showers for Wednesday evening into Thursday morning. Ensemble mean QPF values remain light for this time period. Global guidance generally agrees on less QPF across SE MA and RI up into NE MA (especially in the ensembles), but the latest NAM disagrees, indicating higher amounts across those areas. This spread lines up with the uncertainty that remains regarding track for these shortwaves. We are monitoring the chance for a coastal storm towards the end of the week. The latest trends are pointing towards the low passing to the north of southern New England, which would mean that more significant impacts would all shift to northern New England. Ensemble probabilities for an inch or more of total snowfall (using a 10:1 ratio) through Friday evening remain below 10-20 percent, and are closer to 0 percent for 24 hour snowfall across much of the region. The only exception is the Berkshires where ensembles have around 50 to 60 percent probabilities for +1" of snow over 24 hours (ending midnight Friday). Much can still change this far out from the event, and the system could still shift towards a more favorable track for more significant impacts for southern New England depending on how the mid level trough evolves. But the latest guidance backing off from this system is worth noting, especially with agreement across different model suites. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/...

No changes have been made to key messages for the week. && .KEY MESSAGES... 1) Dry high pressure will dominate through Tuesday, yielding low relative humidity values both Monday and Tuesday afternoons. 2) Dangerous fire weather and marine conditions possible as gusty winds and low humidity arrive behind a mostly dry cold front Thursday into Friday. 3) Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. && .DISCUSSION... KEY MESSAGE 1: Dry high pressure will dominate through Tuesday, yielding low relative humidity values both Monday and Tuesday afternoons. Surface high pressure centered over the southeastern states on Monday will slowly drift towards Texas on Tuesday. Aloft, broad troughing will dominate over the eastern CONUS into mid-week as a closed low north of New England on Monday pushes northeastward. Given the northwesterly flow aloft, much drier air will be advected into the region. This is shown through multiple model forecast soundings, depicting a very dry column of air across southeastern SC and southeastern GA. The drier air will yield RH values on the order of 20-30% across the region. With the surface high pressure centered over the southeastern states, winds across southeast SC and southeast GA will top out only around 5 to 10 mph Monday and Tuesday afternoons. While the criteria for a fire weather headline is met in regards to the RH values, wind speeds are significantly below Fire Danger Statement/Red Flag Warning criteria. While no fire weather headlines are anticipated at this time, individuals should be cautious as fires can spread quickly under these conditions. KEY MESSAGE 2: Dangerous fire weather and marine conditions possible as gusty winds and low humidity arrive behind a mostly dry cold front Thursday into Friday. Approaching shortwave Tuesday night will encourage the development of weak low pressure within a front over the Bahamas, which will lift north well off our coast Wednesday. Current expectation is very dry air in the low levels will limit the potential for any significant rainfall over land, though a few showers could work back over the beaches. A strong cold front associated with low pressure lifting across New England will then approach from the west Wednesday night, crossing the area early Thursday. Low level moisture is limited ahead of the front, and, with only modest upper forcing coinciding with the strongest frontogenesis Thursday morning, the overall rainfall potential with the front looks very limited. Of greater concern is the strong gradient in the wake of the front as high pressure builds in from the west. This, in combination with peak mixing and downsloping flow in the low and mid levels, will likely result in wind gusts Thursday afternoon on the higher end of the guidance envelope, with 25 to 30 mph gusts likely, with some gusts to 35 mph possible over land. A Lake Wind Advisory will likely be necessary, with wind over the coastal waters possible gusting to Gale Force (~10-30% chance) into Thursday night. Additionally, RH values will be rapidly dropping through the afternoon and evening, and critical RH`s (<25%) could be approached by late Thursday afternoon. A faster frontal passage would result in a greater potential for adverse fire weather conditions later Thursday afternoon/evening. Very dry air remains in place Friday, with the 30-50% probability of RH values of <25% away from the immediate coast. However, the gradient will be much weaker Friday, so Red Flag Warning conditions currently look unlikely. KEY MESSAGE 3: Very cold temperatures will occur Friday morning, with lows in the upper teens to lower 20s away from the beaches. Strong cold and dry air advection will occur in the wake of a cold front Thursday afternoon and evening. Then, overnight Thursday night, the gradient will weaken significantly and radiational cooling will ensue. The guidance envelope shows most likely lows away from the immediate coast in the upper teens to lower 20s. If several hours of radiational cooling occurs, lows on the lower end of the envelope, potentially in the mid to upper teens, are very realistic given dew points in the lower teens. With light winds, the wind chill will generally be the same as the temperature, so Cold Weather Advisories could be needed for much of the area. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... VFR conditions will prevail at CHS/JZI/SAV terminals through 06Z Wednesday. Extended Aviation Outlook: VFR conditions prevail for KCHS, KJZI and KSAV through late week. NW winds could gust to 25 to 30 kt Thursday afternoon as chilly high pressure builds in quickly behind a strong cold front. && .MARINE... Conditions will remain below Small Craft Advisory criteria through Wednesday as surface high pressure dominates over the forecast area and adjacent marine waters. Weak low pressure passes off the coast Wednesday, but a weak gradient on the west side of the low keeps benign marine conditions in place despite increased shower chances. A strong cold front will cross the area late Wednesday night into Thursday morning, with gusty NW winds developing behind the front Thursday through Thursday evening. There is currently a low (10-30%) chance for Gale Force gusts, but at the very least Small Craft Advisories are likely. Winds and seas subside quickly Friday morning as high pressure builds in from the west. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. && $$ |

Issued at 1052 PM CST Mon Jan 12 2026 A weak southern stream upper low is currently near the Big Bend region. It will move eastward across the state Tuesday and Tuesday night as it becomes absorbed into an amplifying trough across the central and eastern CONUS. Local radar echoes have been mainly virga so far, but a couple stations near and southwest of Corpus Christi have reported a trace-0.01" of light rain. That batch of light rain may brush areas near the coast overnight. Better lift arrives with the upper low during the day on Tuesday along with the left-exit region of an upper-level subtropical jet streak. Mid-levels will be fairly saturated, but dry air will remain in place at low-levels. Expect at least some sprinkles to move through during the day with a low chance of light measurable rain at any given location. Associated cloudcover will knock at least a couple degrees off of high temperatures. A highly amplified upper-level pattern will be in place through the end of the week and into the weekend, with ridging along the West Coast and a deep trough over the eastern CONUS. Several shortwaves will reinforce the eastern CONUS trough. Southeast Texas will be underneath dry, generally northwesterly flow aloft along the back side of the trough. Two dry frontal passages are expected Wednesday afternoon and Friday night with brief warm-ups prior to the fronts with southwest winds, followed by an increase in northerly winds behind the fronts. Some deamplificiation of the pattern may take place by early next week. JDavis && .AVIATION... (00Z TAF Issuance) Issued at 549 PM CST Mon Jan 12 2026 All sites at VFR with VFR prevailing through the period. BKN to OVC mid-high level clouds will continue through the period. NE winds will give way to more light and variable winds overnight. Winds will become SW inland during the day Tuesday. Bailey && .MARINE... Issued at 1052 PM CST Mon Jan 12 2026 Mariners should anticipate negative tide levels through the week, especially around low tide cycles in the central and northern half of the the bays. Will maintain the Low Water Advisory in place, though values will probably fall just short of criteria (-1 MLLW) Tuesday morning. A Wednesday daytime frontal passage will push additional water out of the bay, with another Low Water Advisory likely being needed for Thursday morning. Mariners should be cognizant of grounding risks. Light winds and low seas are expected Tuesday with a low chance for light rain. The next front is expected to push into the waters Wednesday afternoon with increasing northwest and north winds filling in behind it Wednesday night into Thursday. A Small Craft Advisory will likely be needed during this time period. JDavis && .PRELIMINARY POINT TEMPS/POPS...
