.SYNOPSIS...
A series of very weak troughs and fronts will impact Eastern NC
this week with Bermuda high pressure anchored offshore. The
high builds into Eastern NC late week through the weekend with
dangerous heat and humidity.

&&

.NEAR TERM /THROUGH TODAY/...
As of 215 AM Wed...

Key Messages...

- Hot and humid with scattered showers and thunderstorms

Latest analysis shows high pressure offshore with weak troughing
inland. Showers and isolated thunderstorms beginning to blossom
over the Gulf Stream early this morning. Expect sct coastal
convection to transition inland by late morning and this
afternoon as seabreeze develops. Will continue chance pops.
Meager shear will keep tstms pulse like with low svr threat.
Hot and muggy again with highs in the upper 80s to low 90s, and
heat indices in the lower 100s.

&&

.SHORT TERM /TONIGHT/...
As of 215 AM Wed...Expect convection to wane with loss of
heating this evening, becoming mostly dry with sct showers and
storms offshore. Temps near climo with lows falling into the mid
to upper 70s.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
As of 130 AM Wednesday...

Key Messages...

-Diurnal showers and thunderstorms are expected through the long term

-Potential for hazardous heat from Thursday through Monday

Jet stream and a stream of shortwaves are pinned well to our north
with ridging dominating the synoptic flow over the SE through the
long term. This brings a typical summertime pattern to the CWA
through the long term, with daily pulse t-storms fueled by high
instability, low shear, and high PWATs with slow storm motions
bringing frequent lightning, brief periods of heavy rain, and strong
(sub-severe) wind gusts. Thursday and Friday drier mid and upper
levels keep rain chances a bit below climo, but then an increase in
moisture for the weekend into early next week brings rain chances to
at or above climo. With ridging built over the region, Thursday
through Saturday high temps in the mid 90s paired with Tds in the
mid to upper 70s brings apparent temperatures between 100-110F. Heat
will be a concern Thursday through Monday, and proper precautions
should be taken by those who either work outdoors or are planning on
spending an extended amount of time outside later this week and
weekend.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
SHORT TERM /through tonight/...
As of 215 AM Wed...Pred VFR conditions expected through the
period, with potential for patchy MVFR stratus early this
morning and sct convection this afternoon. Sct to bkn mid/high
clouds and SSW breeze should limit fog threat this morning,
though terminals could see a brief period of MVFR stratus
through mid morning. Scattered showers and tstms expected to
develop again this afternoon, which could briefly bring sub-VFR
conditions to the terminals.

LONG TERM /Thursday through Sunday/...
As of 130 AM Wed...There will be a chance for some diurnal
showers and thunderstorms through Sunday. Though the lowest
chances to see showers or thunderstorms will be on Thursday and
Friday as a relatively drier airmass overspreads ENC. Either
way, a low end threat at sub-VFR conditions each afternoon and
early evening is expected across ENC into this weekend. If it
does rain, then there will also be a fog and low stratus threat
at night as well for areas that see meaningful rainfall.

&&

.MARINE...
SHORT TERM /through tonight/...
As of 215 AM Wed...Latest obs show SW winds 10-15 kt with seas
2-3 ft. Typical summertime pattern will continue through
tonight, with SSW winds increasing to 10-20 kt this afternoon
and early evening as thermal gradient strengthens. Could see a
few gusts approach 25 kt by late afternoon/early evening over
the eastern Pamlico Sound, Roanoke/Croatan Sounds but still
looks too marginal for SCA. Seas will build to 2-4 ft this
evening. Scattered showers and a few storms will likely impact
the coastal waters and sounds through mid morning, transitioning
inland this afternoon.

LONG TERM /Thursday through Sunday/...
As of 130 AM Wed...Conditions continue deteriorating Thurs as the
thermal trough strengthens further. Winds increase to 15-25 kts with
higher gusts across all waters. This will bring a threat for SCA
conditions, mainly across the Pamlico/Croatan/Roanoke Sounds and the
central coastal waters which will have the most favorable
orientation for SCA`s given the wind direction. As we get into the
weekend winds do ease slightly as ridging to our east weakens,
allowing SW`rly winds to fall from 15- 20 kts on Fri to 10-15 kts on
Sat and Sun. 2-3 ft seas on Wed along our coastal waters increase to
3-5 ft Thurs night in response to the stronger winds with seas then
lowering down to 2-4 ft on Fri and 2-3 ft for the weekend as winds
ease. Diurnal showers and thunderstorms will be possible through the
period with the lowest chances to see thunderstorms on
Thurs/Fri.

.SYNOPSIS...
Bermuda high pressure along with an inland trough will
dominate with mainly localized showers and thunderstorms each
afternoon. Should see increasing heat risk late in the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Typical summer day with afternoon showers/storms. There is still
some question on coverage as formation will be more with smaller
scale features, but thoughts are that things will start to form
along the sea breeze and then graduate more towards along outflow
boundaries. No severe weather is anticipated but rain may be heavy
at times. Activity will calm down into tonight where confidence on
fog is low given a persistent southerly breeze. Highs near 90 and
lows in the lower to mid 70s.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
At the sfc, a southerly return flow around the Bermuda
High will continue. Ridge will continue to build in the mid
levels with H5 heights increasing to 596 dam and deep westerly
downslope flow in the low to mid levels by Fri. High temps in
the in the 90 to 95 range on Thurs will increase further to 94
to 98 range on Fri. This will lead to increasing heat risk and
potential for a Heat Advisory. Lows in the mid to upper 70s will
not provide much relief at night. May see a front/trough run by
to the north Fri night, but ridge should keep convection limited
for the most part.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Hot and humid weather will continue into the weekend with temps
well into the 90s. Expect potential for heat headlines to
continue. By Sunday, the ridge gets suppressed a bit to the
south with shortwave riding by to the north. May see
lingering trough/front helping to increase chc of convection
over the Carolinas into early next week with heat letting up a
bit and diminishing chc of heat risk or headlines.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
MVFR/IFR stratus possible tonight as lower clouds move onshore to
inland through the morning. The coverage will be the main question,
so have left things SCT but momentary filling in of CIGs may be
possible here and there. Otherwise, afternoon showers and storms
will bring spotty restrictions to terminals with clearing expected
tonight. Low confidence on fog and stratus towards the end of the
period, but stratus may again be possible.

Extended Outlook...Intermittent flight restrictions are possible
each day due to daytime/evening convection and potential early
morning fog/stratus.

Through Tonight...Southerly winds generally 10-15 kts, highest in
the afternoon. Seas generally 3-4 ft with a SSE swell at 2-4 ft and
6 seconds.

Thursday through Sunday...Bermuda High will maintain SW winds up
to 15 kts with gusts up to 20 kts, especially in aftn sea breeze
near shore. Seas will mainly be in the 3 to 4 ft range. A
longer period SE swell will mix in. A front/trough will drop
southward Fri night into the weekend with winds turning slightly
more WSW.

.DISCUSSION...
Issued at 114 AM CDT Wed Jul 16 2025

Things are looking a little more active for the upcoming days. The
entire next three days or so will be centered around Invest 93L and
what comes of that. Currently the mid level center is located near
the Big Bend Region of Florida embedded in a blob of storms. However,
it appears that what low level center we had has lost its way. We
have the body of a potential system but the legs wandered off into
north Florida and until we grow a new pair of legs this system is
likely to struggle. Unfortunately, the moisture will still arrive
eventually leading to a rather soggy next couple of days and the
potential of heavy rainfall on Thursday.

Today will be rather similar to Tuesday. Rain chances will likely
remain confined to the coast and east of I-65 during the afternoon
where the influences of the Invest are most felt. The biggest thing
will be the potential for heavy rainfall from slow moving storms.
PWATS will be above 2 inches with overall likely flow leading to
slow moving and efficient rain makers. However, with how weak the
low is and no true focus for training convection, any flooding rain
would likely be isolated and focused around the poor drainage areas
of the coastal cities. This is rather noticeable in some of the
ensemble guidance with some individual members hinting at some
higher totals approaching 3 to 5 inches but it is sporadic in nature
with an overall mean of around 1 inch. This does not give much
confidence in flooding and thus we will not go with any sort of
flood watch at this time. With the system likely remaining rather
weak and disheveled and the upper ridge in full control, expect
temperatures to get warm across areas northwest of I-65. Heat
indices will likely climb to the 106 to 108 range across
southeastern Mississippi during the afternoon and overall heat risk
will be high across this area. Could consider a heat advisory;
however, hotter times are coming and overall heat stress will likely
be confined to a rather short period. Thus have differed on issuing
one.

Heading into the end of the week, things will remain active with the
potential tropical low slowly meandering towards Louisiana. The good
news is guidance is far from enthused with this system as the upper
ridge continues to push back on the storm and its limited time over
water/proximity to land should keep things in check. Even if it did
organize more, the stronger ensemble members take it further south and
west into the Gulf (more time over water and further from land)
before making landfall in south central Louisiana well west of our
area. A stronger storm would also help boost the ridge to our north
and likely drive the storm west and keep us in the clear from most
of the nasty stuff. The biggest concern looks to be Thursday as rain
chances will be highest. PWATS will climb into the 2.25 to 2.5 inch
range along the northeastern side of the system. Much like
Wednesday, these moisture levels certainly support a risk of
efficient rain makers; however, the aforementioned weaker system
coupled with a stronger ridge really plays against a more widespread
heavy rain threat without a true focus. IF and thats a big if, the
system strengthens a little quicker, then a more focused rain threat
may materialize across coastal Alabama and maybe into southeastern
Mississippi. Overall guidance isn`t enthused and thats probably an
artifact of the system struggling overall. Rain chances will
continue through Friday before the ridge builds back in for the
weekend. A high risk of rip currents will begin on Thursday and last
til at least Saturday as increasing wave action and onshore flow
from the invest begins.

The switch will flip rather quick as we move from wet and soggy to
hot and sweaty. As whatever this system becomes slowly moves onshore
across Louisiana, the upper ridge will quickly build over the area
in its place allowing for the furnace to turn up. With increasing
subsidence, expect rain chances to decrease through the weekend and
into early next week but temperatures and heat indices will go up.
Legit heat advisory material will be possible during this period
with the combination of remnant moisture from the tropical system
and the subsidence from the ridge combine to make the great gulf
coast pressure cooker. Expect high heat risk days for most of the
area Sunday through Tuesday and potentially extending into the
middle part of the week. BB-8

.SYNOPSIS...
Heat and humidity peak today but lasts into Thursday. A cold
front will bring showers and thunderstorms Thursday before
relief from the heat arrives this weekend. Drier and more
seasonable weather is ahead next week.

&&

.NEAR TERM /THROUGH TODAY/...
215 AM Update

Key Messages:

* Peak of heat and humidity today.

Upper ridge builds into southern New England today which brings
rising heights and warming temperatures aloft, making this the
hottest day of the week. Heat indices this afternoon are
expected to top out around 100 degrees in many areas away from
immediate coast where onshore winds will keep it slightly cooler
(but still hot). Along E MA coast, gradient remains weak enough
to support sea breezes for a few hours from later this morning
into early afternoon, then we should see winds shift back to
S/SW which will boost temperatures there into 90s.

Speaking of S/SW flow, we remain in the usual summertime pattern
of nighttime and early morning low clouds/fog near South Coast,
Cape Cod, and Islands which should persist today and through the
end of the week.

Despite a lot of instability, ridge will also help suppress
convective development as forecast soundings show a strong cap,
but it`s possible we see a stray shower or even a thunderstorm
form toward sunset as boundary layer cools off just a little,
similar to what we saw yesterday across interior. However, we
don`t have a lifting mechanism strong enough to overcome mid
level cap so it will be difficult to see anything organized or
potentially severe.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...
215 AM Update

Key Messages:

* Showers/non-severe storms possible overnight into Thu AM.
* Severe storms possible late Thu afternoon/evening.
* One more day of dangerous heat and humidity Thu.

Lead short wave over Ohio Valley heads east tonight as upper
ridge becomes suppressed and retreats offshore. It will provide
larger scale lift upon an airmass that is already unstable with
increasing PWATs, which should result in showers and perhaps
embedded thunderstorms overnight into Thu morning, especially
across western/central MA and CT.

High-res models show a few potential outcomes, either an area
of weakening convection heading into southern New England
overnight, or what`s been called the "7-10 split" where
convection splits into two areas where one lifts to our north
and the other shifts south, leaving much of the area dry in
between. In either case, none of the convective parameters are
favorable for severe weather, but certainly the anomalous
moisture could bring brief downpours.

Once short wave heads offshore later in the morning, subsidence
in its wake should prevent any additional activity from
developing until the approach of the cold front later in the
afternoon and evening. This is the main time frame of concern
for severe weather, especially in western/central MA and
northern CT, as environment should feature plenty of instability
with surface-based CAPE over 2000 J/kg, sufficient 0-6km shear
of 25-30kt, decent mid level lapse rates, and strong 0-1 km
shear in excess of 150 m2s2. Most of the high-res models show
potential for discrete storms ahead of front with potential for
wind damage and even a few tornadoes, before eventually merging
into small lines or segments capable of producing wind damage.

That said, there are timing differences among hi-res models and
ensemble members with some showing an earlier start to afternoon
development. Should that verify, that would lessen the
potential for severe weather since most of the parameters noted
above occur later in day, closer to cold front itself, and are
less favorable during the early to mid afternoon hours.
Something to keep in mind which hopefully gets resolved in later
runs.

Aside from the convection, we will have one more day of
dangerous heat and humidity, although extent of cloud cover
could limit afternoon heating. For now, we are expecting heat
indices well into 90s once again, but probably not as high as
what we expect today.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Updated 215 AM

Key Messages:

* Still hot but lower humidity Fri.
* Relief from heat arrives this weekend

Once cold front moves offshore Fri, W/NW flow will bring drier
air into region but airmass really doesn`t cool off sufficiently
until this weekend, when we should see temperatures more typical
of mid July which will last into early next week.

Overall, dry weather is expected but the front may return north
by Sunday which would bring scattered showers/storms, before
another short wave kicks everything out to sea Monday and
Tuesday.

Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

High confidence.

Low clouds and fog will bring IFR/LIFR conditions to much of
South Coast, Cape Cod, and Islands through sunrise, possibly
advancing into NE CT and most of RI/SE MA. These lower ceilings
will retreat southward after sunrise leaving VFR conditions by
early afternoon, but will then return around sunset and persist
tonight once again with widespread IFR/LIFR into Thu morning.

Otherwise, VFR with S/SW winds through tonight. Gradient remains
weak enough to allow for sea breezes along E MA coast for a time
later this morning into early afternoon, before S winds return.

Later tonight, areas of MVFR ceilings develop with showers
possible in western New England overnight, perhaps spreading
into more of southern New England Thu morning. Conditions then
improve again to VFR but we may see a round of showers/storms
later in day, especially in western MA/western CT.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday Night: VFR. Breezy. Slight chance SHRA.

Friday through Saturday: VFR.

.SHORT TERM...
(Today)
Issued at 105 AM CDT Wed Jul 16 2025

Yesterday was quite warm with very little convection. That said
there were still a few storms out there but overall most of the
region remained rain free and about half of the area likely
remains rain free again today. This will lead to another warm one
but the eastern half of the area may see some cooling rain in the
afternoon and maybe as early as midday.

Today will begin very warm and humid. The ridge that is helping to
steer the flow and our Gulf disturbance remains entrenched across
the southeastern CONUS and Lower MS Valley nosing down into
southeastern TX. This is leading to very warm LL temps across the
Lower MS Valley which is sinking down into southern MS and SELA but
h925 temps are only around 26/27C. Under optimal conditions this
would lead to mid to even upper 90s easily but this ridge again
isn`t that August early September type ridge So getting much above
96 is going to be very difficult combine the fact that storms could
be moving in from the east and looking at radar last night and
satellite there was a large area of precip that has been displaced
well west of our Gulf disturbance. This surge of moisture is already
moving into the area and there is a good chance that we could see
convection begin to develop along coastal MS and coastal SELA late
morning/midday. In addition high clouds are already quickly
spreading west and could also impact temps today and that could help
keep the heat index in check some. The other issue that has been
occurring for the last week or so is the mixing. We have really been
able to mix these dewpoints down efficiently north of I-12 and north
of I-10 in coastal MS the for some reason and that has helped keep
the heat index under control in and around places like BTR and MCB.
With all of that there are some question with the heat today however
around the lakes and on the immediate MS coast where the moisture is
higher it has been more oppressive and the only thing that will help
to keep it in check will be convection...which is a concern today.
That said the heat advisory that is currently out...will not make
changes to it yet as see if convection does fire early today. /CAB/

.LONG TERM...
(Thursday through Tuesday)
Issued at 105 AM CDT Wed Jul 16 2025

The extended portion of the forecast is highly focused
on the system over the northeastern Gulf. Models have begun to come
more in line with this system really hugging the northern Gulf but
remaining on the weak side from an organization standpoint. Overall
no major changes made to the forecast with the risk of very heavy
rain still possible across the region mainly Thursday through Friday
night but rain could linger around the area into the weekend.

So first...there is still some potential for heavy rain with flash
flooding possible however the confidence is not the highest given
the latest trends. That said it will not take much to get some
rather high rain totals over portions of the CWA given the amount of
moisture over the area and favorable upper lvl environment in place.
The tropical wave we are watching is still sitting at 40% of
developing into the tropical depression in the next 48 hours but it
is not looking very organized at this time. It moved inland
yesterday over the FL peninsula but almost as soon as it moved
inland it became detached with the sfc low quickly surging north
while the mid lvl low continued west. By 5z the LL center was east
of TLH and approaching southern GA while the mid lvl center was
south of Apalachicola. So the question is can a sfc low redevelop
underneath the convection and then will it just continue to barrel
west towards the LA coast or will it struggle to see much if any
consolidation with a very messy and disorganized system approaching
the coast Thursday. At this time it is beginning to feel like we may
want some consolidation as this would likely focus the heavier rain
and along and south of the eventual track which would likely be the
immediate SELa coast and the coastal water. However, if this is
messy disorganized system convection will be more diurnal in nature.
Yes that will keep us from seeing widespread rain and a complete
washout everywhere but will be more favorable to seeing scattered
storms which will be extremely efficient rain producers. PWS are
still expected to be well over 2" and models are now explicitly
showing PWS near 2.5" at times Thursday and Friday. The upper lvl
setup is still very favorable Thursday and into Thursday evening so
the concern may be trending to scatted storms tapping into that
rather extreme moisture with a nice diffluent setup aloft and weak
steering currents. The problem then becomes storms easily capable of
dropping multiple inches of rain in under an hour but that alone
isn`t necessarily a problem, the problem is just where that would
occur. There are many locations that will have no problem handling
even more than 2-3" of rain in an hour but if that falls over the
wrong locations say like any of our more urban areas that will lead
to big problems.

Now the obligatory and we hate to say but "there is still a lot of
uncertainty". Most of the time there really is and in this case
there are but trends in radar and satellite along with guidance are
suggesting that there is a good chance that the bulk of the heavy
rain will remain along and south of the coast. Small
adjustments/changes can have rather significant implications in
impacts and with our system there are a few things that could lead
to most of the area seeing relatively light impacts. The biggest
determining factor in this case is track and there are more than a
few solutions suggesting that it will struggle to really develop and
remain just a little too far south with most of the rain hanging
south especially since there is a good chance that a bulk of the
rain will remain on the southern side of this system.

At this time we will continue to advertise widespread 2 to 4 inches
of rain with isolated amount of 6 to 8 possible. However if trends
continue these values may trend down some more or at the least the
area may be a little more confined to coastal LA. The one caveat is
if this just remains a disorganized mess where convection become
highly diurnal in nature and that would then lead to scattered
storms across the entire CWA leading to isolated pockets of very
heavy rain. /CAB/

Area Forecast Discussion
National Weather Service Charleston SC
207 AM EDT Wed Jul 16 2025

.SYNOPSIS...
Atlantic high pressure will prevail through early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today: Aloft, the east to west oriented ridge axis will
continue to extend into the GA/SC coast. At the surface, The
subtropical high will be the primary feature and will drive the
low-level flow pattern across the forecast area. Overall, today
does not look particularly active for convection. The ridge
aloft will help to keep coverage down, and model soundings are
rather warm and only depict MLCAPE values of up to around 1,500
J/kg. Instead, we will likely continue to see weak convection
push onshore from the coastal waters within the onshore flow
throughout much of the day. Any diurnal land-based convection
that develops also looks to be weak and not a severe threat.
Also, the locally heavy rain threat is low thanks to the
progressive nature of this convection with storm motion on the
order of 15-20 mph. Temperatures are forecast to top out in the
low 90s, with heat indices mostly in the low 100`s and some
isolated values into the mid 100`s.

Tonight: Overall, little change to the pattern overnight. Any
lingering land-based convection should dissipate through the
early evening, though there will still likely be some shower
activity over the coastal waters trying to push onshore at
times. The low-level flow will start to become more south-
southwest or southwest with time which should keep most of the
nocturnal convection across the coastal waters off the coast.
Similar lows to the last few nights, with temperatures falling
into the low to mid 70s inland and hanging around in the upper
70s along the coast.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
A strong deep layered ridge will prevail Thursday through
Saturday, bringing hot and humid conditions. Friday and Saturday
will feature highs in the mid/upper 90s, dewpoints in the
mid/upper 70s, and heat indices topping 108 in some places. We
could need Heat Advisories for part of the area both days. An
increase in upper level subsidence will limit PoPs to 20-30%.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
The upper ridge axis will shift west of the area late in the
weekend into early next week, allowing some shortwave energy to
rotate in from the north. This could result in an increase in
diurnal convection coverage Monday and Tuesday. Toasty
conditions will continue into Monday, with possible Heat
Advisories both days. Temps may cool slightly by Tuesday.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
The 06z TAF period begins with VFR conditions at KCHS, KJZI,
and KSAV. The main issue for through sunrise will be shower
activity moving onshore and possibly producing brief periods of
MVFR conditions. Over the next few hours, the best chances are
expected to be around KSAV. Then around sunrise and through mid
morning, the focus for shower activity should shift up more into
the KJZI and KCHS area. By the early afternoon, most of the
shower activity should shift inland of the terminals. Winds will
be a bit stronger today with some gusts into the 16-20 knot
range expected.

Extended Aviation Outlook: VFR will mainly prevail throughout
the period, however brief flight restrictions are possible
within showers and thunderstorms that develop in the afternoon
and/or evening hours.

&&

.MARINE...
Today and tonight: Subtropical high pressure to the east will
be the primary feature driving the flow across the local waters
through the period. Winds today will be southerly with speeds
mostly in the 10-15 knot range, though there could be an
occasional 20 knot gust. Overnight, winds will slightly start to
veer around to become more south-southwest late. Speeds should
be the same, mostly 10-15 knots with occasional gusts up to 20
knots. Seas should average 3-4 feet through the period. We will
likely continue to see isolated to scattered showers and
thunderstorms across the coastal waters today within the onshore
flow. This activity isn`t expected to be particularly strong
and there is a low probability of strong wind gusts.

High pressure will prevail Thursday through Monday, maintaining
typical summertime weather in the marine area. No headlines
expected.

AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
201 AM EDT Wed Jul 16 2025

.SYNOPSIS...
An unsettled weather pattern continues through Wednesday with
scattered thunderstorms and localized flooding possible. Hot and
humid conditions, with a somewhat lower storm coverage is
expected Thursday and Friday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
As of 945 PM EDT Tuesday...

Key Messages:

- Flood Watch has been cancelled all areas with no additional
heavy rainfall and flash flood potential expected overnight.

- Areal Flood Warnings have been extended into early Wed morning
for portions of southside VA where widespread road closures
remain in place due to lingering areas of high water.

The latest WX analysis indicates a broad upper level ridge centered
across the western Atlantic, ridging into the SE CONUS, with an
upper level trough across the northern Plains and central/ern
Canada. At the sfc, a weak pressure pattern is in place, with a
quasi-stationary boundary now mainly N of the local area.
Earlier showers and storms have diminished, with just a few
spotty showers with embedded tstms over the MD eastern shore
(mainly along the coast). Additional heavy rain and flash
flooding is not anticipated, allowing the cancellation of the
Flood Watch. Given a fairly widespread region of lingering high
water and road closures, decided to extend the Areal Flood Watch
across southside VA into early Wed morning. Otherwise, mainly
dry overnight, with perhaps a few additional showers manly along
the coast. Low stratus and patchy fog will probably develop
overnight, but widespread dense fog is unlikely. LOws will
mainly range in the lower to mid 70s.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/...
As of 308 PM EDT Tuesday...

Key Messages:

- Unsettled pattern continues into Wednesday with additional
rounds of showers and storms as the front stalls NW of the
area.

A similar pattern continues into Wednesday, with a bit more flow
aloft possible during the afternoon and evening as a shortwave in
the SW flow aloft potentially moves across the region. The frontal
boundary currently stalled to our NW will linger near the area and
could be the target of storms, so the areas of highest rain chances
will shift to the northern portions of our forecast area tomorrow.
No real changes in the airmass through Wednesday with PWATs
remaining around 2" so the threat for localized heavy rainfall and
gusty winds persists. Due to the low flash flood guidance across the
area, WPC has placed our area in a Marginal ERO to account for that
and the possibility of scattered coverage. Continued seasonally hot
and humid with highs in the upper 80s to lower 90s. Warm and muggy
Wednesday night with lows in the 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
As of 308 PM EDT Tuesday...

Key Message:

- Heat and humidity build late in the week with Heat Advisories
possible.

Looking ahead to late-week, upper ridging will build northwards into
the area through the weekend. Convective coverage will diminish to
isolated on Thursday. With the decreased cloud cover and storms
combined with the upper ridging, temperatures will be able to climb
into the lower to mid 90s Thursday through Sunday with the northern
part of the area possibly only reaching the upper 80s Friday through
Sunday. The shower coverage will be at its lowest on Thursday, and
with partly cloudy skies forecast in the eastern and dew points
creeping up into the mid-upper 70s, Heat Advisories may be required
for portions of the area. A front will approach the region Friday
and linger just north of the area through the weekend, which could
help initiate showers and thunderstorms in the afternoon. With
shower coverage a little higher Friday through Sunday, Heat
Advisories may not be required, though we could see the SE/S portion
of our area reach the 105F+ criteria.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
As of 200 AM EDT Wednesday...

High pressure is centered off the Southeast coast as of 06z.
Primarily VFR, with the exception of developing IFR stratus at
and around RIC. The wind is very light out of the SSW. IFR/LIFR
stratus is expected to persist at RIC through 10-12z (along with
some MVFR vsby). Otherwise, MVFR cigs are possible at PHF and
SBY after 09-10z. Any lingering MVFR cigs after 12z are expected
to lift by 14z. Scattered showers/tstms are expected once again
Wednesday aftn, but with less coverage than previous days.
Continued PROB30 groups for tstms (19-23z) for all sites but
ECG. The wind is expected to be SW 8-12kt with a few gusts to
20kt Wednesday aftn. Any showers/tstms diminish Wednesday
evening, with mainly VFR conditions Wednesday night.

Mainly VFR Thursday through Sunday. A lower shower/tstm
coverage is forecast Thursday, with a higher chc Friday/Saturday
as another front drops into the region.

&&

.MARINE...
As of 308 PM EDT Tuesday...

Key Messages:

- Benign marine conditions continue through Wednesday night, outside
of local influences from afternoon and evening thunderstorms.

- Small Craft Advisories are likely Wednesday night into Thursday,
mainly across the Chesapeake Bay and lower James River.

Strong high pressure well offshore continues to keep the prevailing
southerly flow across the local waters. Winds are mostly S-SE 5-10
kt with gusts from convection up to 15 kt. The pressure gradient
sharpens some into Wednesday as low pressure tracks well N of the
area through the Great Lakes region. 10-15 kt SW winds are expected
through Wednesday. Beginning Wednesday night, SCA conditions are
likely, as local probabilities now show 80-99% for 18 kt sustained
winds over the Ches. Bay and coastal waters. Although, confidence
for headlines over the coastal waters is lower, as the probability
for sustained 25 kt is only up to 10%. Winds may remain elevated
through the day Thursday and begin to decrease Thursday night. Since
the timeframe is still a few periods out, opting to hold off on
headlines for now. Waves and seas remain benign around 1 ft and 2
ft, respectively. Although likely staying benign through the
forecast period, waves and seas will increase slightly Wednesday
night to 2-3 ft and 3-4 ft, respectively, before decreasing again
Thursday night.

There is a moderate rip current risk for the northern beaches
tomorrow as seas will build throughout the day and the swell will
become more shore normal. A low risk remains for the southern
beaches.

Isolated to scattered afternoon/evening showers/tstms will continue
much of the week. The main hazards with tstms will be brief strong
wind gusts, frequent lighting, and reduced visibility in heavy
rain.

.NEAR TERM...
(Today and tonight)
Issued at 158 AM EDT Wed Jul 16 2025

A weak tropical disturbance will continue to move westward through
the area today. Most of the convection has remained offshore during
the overnight hours. As the system continues moving westward, bands
of showers and thunderstorms on the east side of the system are
expected to develop across the area with southerly flow. Pockets of
locally heavy rainfall are possible, especially near the coast.
Overall, the threat of flooding is non-zero, but so far it looks too
isolated to warrant any flood watches. The best chance at seeing
heavy rain will probably occur from mid-morning into early afternoon
across the coastal areas and extend inland across the Florida
panhandle and big bend. High temperatures will be noticeably cooler
today with the cloud cover and early start to convection.

For tonight, a few bands of showers and thunderstorms may linger on
the east side of the system near the coast with southerly flow.
Overnight lows will remain muggy in the mid 70s, except upper 70s to
near 80 along the coast.

&&

.SHORT TERM AND LONG TERM...
(Thursday through Tuesday)
Issued at 158 AM EDT Wed Jul 16 2025

On the backside of the tropical disturbance as it progresses
west, southeast flow will be in place Thursday and PWATs will be
in excess of 2 inches for most locations with likely to
categorical pops in place, highest south of I10 and west of the
Apalachicola river to 50% from Albany to Valdosta and north from
there. Highs will generally be in the low to mid 90s with mostly
cloudy skies and scattered showers and storms.

Beginning Friday into the weekend, the subtropical ridge builds into
the southeast US from the east as the disturbance becomes
absorbed in the flow. Each day gets a little warmer while rain
chances slightly decrease. PWATs decrease to under 1.7 inches by
Sunday as drier air becomes more evident in the column above 700
mb as the ridge builds west into the ArkLaTex. This will allow
less coverage of convection, better low level mixing and higher
afternoon temperatures towards the upper 90s. Heat advisories may
be back in play in portions of the area beginning this weekend
depending on how much mixing takes place each afternoon.

Heading into the next work week, a weakness off the east coast may
allow tropical moisture to wrap southwest back across the area with
PWATs increasing back up to over 2 inches. If this occurs, rain
chances appear to increase back to likely which will serve to break
the heat from the weekend with increased convection coverage and
high temps back into the mid 90s.

&&

.AVIATION...
(06Z TAFS)
Issued at 158 AM EDT Wed Jul 16 2025

An unsettled pattern looks to continue later this morning and
through the afternoon as a tropical disturbance (AL93) pushes
westward through the area. MVFR ceilings are currently forecast for
VLD and ABY for portions of early-late morning as some lower clouds
push through. VFR conditions should otherwise prevail, with any
terminal restrictions manifesting as brief MVFR or IFR conditions in
rounds of heavy showers/thunderstorms. Both spatial and temporal
coverage of showers and thunderstorms will be greater than a typical
summertime pattern, with current guidance suggesting activity
picking up as early as 12z for our southern terminals. As the
disturbance pushes westward and southerly flow establishes early
afternoon, scattered to widespread TSRA should develop with a
general south to north progression. The timing of the rounds of
convection is attempted for each terminal site in the TAFs, although
there is considerable uncertainty with timing out finer mesoscale
features and thus further tweaks may be necessary.

&&

.MARINE...
Issued at 158 AM EDT Wed Jul 16 2025

An area of low pressure will track westward today through the
Florida panhandle or just offshore. Winds will turn southerly as the
low moves by, with increasing winds and seas as a result. Cautionary
conditions east of Apalachicola today and all waters tonight into
Thursday night with advisory conditions possible. Beginning Friday
and into the weekend, high pressure builds across the Gulf waters
with winds and seas becoming favorable with wind speeds of 5 to
10 knots and seas of 1 to 3 feet.

&&

.FIRE WEATHER...
Issued at 158 AM EDT Wed Jul 16 2025

Humidity and rain chances will keep fire weather concerns to a
minimum for the next several days.

&&

.HYDROLOGY...
Issued at 158 AM EDT Wed Jul 16 2025

WPC continues the marginal risk for excessive rainfall through the
southern half of the area and especially in coastal areas for the
next several days.

The low pressure area will continue westward through Thursday with
winds turning more onshore and PWATs in excess of 2 inches. 1-3
inches of rainfall, with the higher side of the range closer to
the coast, appears reasonable from WPC. This will lead to isolated
instances of flash flooding, especially in areas that have
received recent heavy rains as well as any training or slower
moving storms.

As the subtropical ridge builds in for the weekend and PWATs begin
to decline, rain chances decrease and thus coverage of rainfall
will lower as well, though this may be shortlived as moisture
increases again at the beginning of the next work week.

Issued at 710 PM CDT Tue Jul 15 2025

The weather pattern through at least the middle parts of next week
for Deep South Texas and the Rio Grande Valley will feature
continued hot, humid, rain-free, and at times breezy conditions.
Global forecast models and ensembles continue to advertise a 591-594
dam sub-tropical heat ridge or "heat dome" retrograding westward
from Bermuda and building over the southeastern U.S. initially
before eventually establishing itself more broadly over the
Southern U.S.

For Deep South Texas and the Rio Grande Valley, this means
seasonable temperatures and mainly minor (Level 1 of 4) Heat Risk
with pockets of moderate (Level 2 of 4) Heat Risk through Friday
(highs temps inland in the mid 90s east to lower 100s west with heat
indices between 100-110F). High temps will hold in the 80s along the
Lower Texas Coast beaches and South Padre Island.

The heat intensifies slightly over the weekend as the aforementioned
594 dam sub-tropical heat dome builds overhead. This will result in
mainly moderate (Level 2 of 4) Heat Risk developing over Deep South
Texas and the Rio Grande Valley over the weekend and persisting
through early next week. Temperature anomalies will run slightly
hotter than normal with triple digit heating becoming more common
along and west of IH-69C.

As highlighted earlier, rain-free conditions will prevail through
the middle parts of next week as the aforementioned heat ridge
stifles any prospects rain. It`s possible that this pattern of
normal to hotter than normal temperatures and mainly dry conditions
could continue through late July/early August, given the time of
year we`re in and model trends.

Winds will also be breezy at times through the forecast period as
the sfc pressure gradient tightens or enhances at times. This
could at times result in moderate seas and rip current risk
through the period.

Finally, we continue to monitor a disturbance that has a medium
(40%) chance of development over the next 2-7 days over the north-
central Gulf. Impacts are not expected at this time across Deep
South Texas, according to forecast trends. However, there could be
some increase in swells over the Gulf Waters later this week.

- Dry, but hot today as weak high pressure builds over the region.

- Increasing tropical moisture will lead to increased coverage of
showers and thunderstorms late Thursday through Friday with
locally heavy rainfall possible.

- NHC continues to monitor a disturbance that will be entering the
northern Gulf on Wednesday, giving it a 40% chance of
development into a tropical system in the next couple of days.
Regardless of development, increased rain chances are likely
late Thursday through Friday.

&&

.DISCUSSION...
Issued at 1202 AM CDT Wed Jul 16 2025

A slight increase in mid-level ridging and drier air moving into the
region will result in the low rain chances on Wednesday through
early Thursday - practically the lowest rain chances we`ve had in
over a week. There still might be an isolated, short-lived shower
that develops thanks to daytime heating on Wednesday afternoon, but
overall we will be rain free through early Thursday. However, the
increasing heights aloft and reduced moisture will lead to afternoon
temperatures climbing into the upper 90s in spots along the I-10
corridor.

Rain chances do begin to increase from the east late Thursday with
chances increasing as we head into Friday. This increase in moisture
will be associated with the disturbance currently located in
northern Florida that the NHC is monitoring for development into a
tropical system as it tracks through the northern Gulf over the next
few days. NHC gives it a 40% chance of development into a tropical
depression or named storm within the next 2 days - more on that in
the tropical section below. Regardless of development, this
disturbance will be bringing a surge in PWATs (up to 2-2.4"), so we
can expect increased rain chances with locally heavy rainfall
possible Friday through early Saturday. WPC has placed the I-45
corridor in a Marginal Risk (level 1 of 4) for Excessive Rainfall on
Friday with eastern Polk, eastern Liberty, and most of Chambers
county in a Slight Risk (level 2 of 4). WPC continues the risk of
Excessive Rainfall into Saturday, but shifts the threats further
east with areas east of I-45 in a Marginal Risk (level 1 of 4) and
the Slight Risk out of our region and more towards the TX/LA border.

Looking past this potential tropical system, expect warming
conditions Sunday into the start of the work week with temperatures
rising back into the mid 90s (and possibly into the upper 90s). With
some drier air in place, rain chances will remain on the lower-side
with PoPs maxing out near 15-20% during the afternoon hours thanks
to daytime heating.

Isolated afternoon showers/storms will taper off this evening as
light and variable winds settle in across the region. Patchy fog
and CIGS may develop over portions of the region during the early
morning hours of Wednesday. MVFR conditions may develop with IFR

Light onshore winds around 5-10kt (and gusts to 15kt) and seas of 2
to 3 feet will persist through the next few days. Drier air has
moved in, so expect much lower coverage of showers and thunderstorms
through early Thursday.

From late Thursday into Friday, rain chances are expected to
increase as a tropical disturbance approaches SE TX from the
northern Gulf region. There still remains uncertainty regarding the
development and track of this disturbance and more information will
be known once the system moves into the Gulf waters on Wednesday.
NHC maintains a 40% chance of formation through the next 48 hours as
the system moves through the northern Gulf. Regardless of
development, we can expect the increased rain chances late Thursday
through Friday or early Saturday. Current wave modeling does not
factor in any tropical development, so its possible that wave
height forecast may increase for Friday *IF* the system does
strengthen. Please continue to monitor the upcoming forecasts.

Not much change in this discussion that hasn`t been talked about in

located in northern Florida, for strengthening into a tropical
system giving it a 40% chance of development within the next 2 days.
Conditions are favorable for development, but there remains
uncertainty in the forecast track of this system. This system
will move westwards through the northern Gulf, but how far west it
gets before turning northwards is uncertain (for now, most
guidance has it turning northwards into Louisiana before reaching
our region, if it develops at all, but this guidance may change
once/if a center of circulation develops), and how far offshore
the center of circulation develops (a track closer to the coast
means less time over water and potentially drier air impacting
development).

Again, regardless of development into a tropical system, an increase
of moisture will lead to increased chances of showers and
thunderstorms in SE Texas late Thursday through Friday.

Summer time conditions will persist through the upcoming weekend and
into next week with a majority of South Texas remaining rain free.
There is an increase of showers and thunderstorms across the
Victoria Crossroads Friday, but chances remain low (10-30%). This is
in response to a potential tropical system that the National
Hurricane Center is monitoring that has a medium 40% chance of
developing across the northeast and northern Gulf over the next 48
hours. No significant impacts are expected in S TX at this time
other than a slight increase in precipitation Friday.

Temperatures will be near to slightly above normal through the rest
of the week and into the weekend. Max heat indices may briefly
approach 110 over the weekend across the Brush Country due to a
slight increase in moisture. The slightly higher heat indices will
lead to a moderate to major risk of heat related impacts over the
weekend.

.DISCUSSION...
Issued at 710 PM CDT Tue Jul 15 2025

The weather pattern through at least the middle parts of next week
for Deep South Texas and the Rio Grande Valley will feature
continued hot, humid, rain-free, and at times breezy conditions.
Global forecast models and ensembles continue to advertise a 591-594
dam sub-tropical heat ridge or "heat dome" retrograding westward
from Bermuda and building over the southeastern U.S. initially
before eventually establishing itself more broadly over the
Southern U.S.

For Deep South Texas and the Rio Grande Valley, this means
seasonable temperatures and mainly minor (Level 1 of 4) Heat Risk
with pockets of moderate (Level 2 of 4) Heat Risk through Friday
(highs temps inland in the mid 90s east to lower 100s west with heat
indices between 100-110F). High temps will hold in the 80s along the
Lower Texas Coast beaches and South Padre Island.

The heat intensifies slightly over the weekend as the aforementioned
594 dam sub-tropical heat dome builds overhead. This will result in
mainly moderate (Level 2 of 4) Heat Risk developing over Deep South
Texas and the Rio Grande Valley over the weekend and persisting
through early next week. Temperature anomalies will run slightly
hotter than normal with triple digit heating becoming more common
along and west of IH-69C.

As highlighted earlier, rain-free conditions will prevail through
the middle parts of next week as the aforementioned heat ridge
stifles any prospects rain. It`s possible that this pattern of
normal to hotter than normal temperatures and mainly dry conditions
could continue through late July/early August, given the time of
year we`re in and model trends.

Winds will also be breezy at times through the forecast period as
the sfc pressure gradient tightens or enhances at times. This
could at times result in moderate seas and rip current risk
through the period.

Finally, we continue to monitor a disturbance that has a medium
(40%) chance of development over the next 2-7 days over the north-
central Gulf. Impacts are not expected at this time across Deep
South Texas, according to forecast trends. However, there could be
some increase in swells over the Gulf Waters later this week.

&&

.AVIATION...
(06Z TAFS)
Issued at 1230 AM CDT Wed Jul 16 2025

Mostly clear skies and generally light southeast winds prevail

.MARINE...
Issued at 710 PM CDT Tue Jul 15 2025

Moderate southeasterly winds and low to moderate seas are expected
to prevail through the forecast period. The National Hurricane
Center (NHC) is monitoring a disturbance that has a medium (40%)

&&

.UPDATE...
Issued at 840 PM EDT Tue Jul 15 2025

Cancelled the Flood Watch early at around 5pm EDT this afternoon,
as the heaviest rainfall associated with Invest 93L had moved out
of the area. Showers and storms have continued this evening,
though rainfall amounts have not been high enough to maintain the
watch. The forecast for tonight is a bit uncertain, as CAMs have
struggled immensely with convection today. However, still expect
showers and storms to diminish this evening overall, though a
chance (~ 20-30%) will continue for the Treasure Coast overnight.
Should showers or storms train over the same areas, minor flooding
could result.

&&

.PREVIOUS DISCUSSION...
Issued at 242 PM EDT Tue Jul 15 2025

Currently-Tonight...Low level circulation of Invest 93L is pushing
onshore north of Volusia County and remains disorganized. N/NE shear
has kept persistent bands of rain and isolated storms S/SW of the
center across areas near to north of a line from Orlando to the
Cape. Some localized heavy rainfall totals have occurred with the
heavier showers and storms, including up to 5-7 inches in northern
Brevard County near Mims and Turnbull where a Flash Flood Warning
was issued earlier today. As low shifts westward across FL into
tonight, this persistent rainfall will also gradually transition
west into this evening. Additional, scattered showers and storms
will be possible farther southeast of the I-4 corridor with daytime
heating through late afternoon/early evening. A Flood Watch
continues through 8 PM from Brevard/Osceola counties northward
through Lake and Volusia for the continued potential for locally
heavy to excessive rainfall totals up to 5-7 inches that may lead to
isolated flash flooding. This activity will then diminish into this
evening, with isolated onshore moving showers and possibly a storm
or two along the coast from the Cape southward overnight. Lows will
be in the low to mid 70s.

Wednesday-Thursday...As Invest 93L moves westward into the northeast
Gulf, NHC is still giving the system a medium (40%) chance of
tropical development into mid to late week as it moves across the
northeastern and north-central Gulf. Across east central FL, waves
of deeper moisture (PW values up to 2-2.3") will lift northward
across the area, keeping higher rain chances in the forecast (up
to 70-80%). Scattered to numerous showers and storms will develop
each afternoon and evening, with greatest coverage focusing
inland. A few stronger storms will be possible each day, with the
main threats including frequent lightning strikes, wind gusts of
40-50 mph, and torrential downpours leading to minor flooding.
Hot and humid conditions are forecast each day. Highs will reach
the upper 80s to low 90s, with peak afternoon heat index values
around 100-105F Wednesday and 102-107F Thursday.

Friday-Monday...(Previous Discussion) Broad mid level ridging
slides over Florida late week and through the weekend. At the
surface, the western flank of the Atlantic high extends across
central Florida and into the Gulf. A more summerlike pattern of
scattered afternoon showers and storms returns, guided by the sea
breeze circulation. High temperatures warm into the low to mid 90s
each day, with peak heat index values forecast to range 100-106
degrees.

&&

.MARINE...
Issued at 242 PM EDT Tue Jul 15 2025

Tonight-Wednesday...An area of low pressure (Invest 93L) is
pushing onshore across the northeast coast of FL and will
continue westward through tonight before exiting into the NE Gulf
Wednesday where it currently has a medium chance (40%) for
tropical development into mid to late week. Poor boating
conditions will continue into tonight, mainly over the offshore
waters where S/SE winds will be up to 15-20 knots. Winds will
then remain out of the S/SE around 10-15 knots into Wednesday.
Seas will be around 2-3 feet for much of the period, except up to
4 feet offshore Volusia County into tonight. Lingering deep
moisture across the area will continue development of at least
scattered showers and storms over the waters, especially overnight
tonight into Wednesday morning.

Thursday-Sunday...Subtropical ridge axis will dominate the weather
pattern late week into this weekend. Winds will remain out of the
southeast through late week and then S/SE into the weekend. Seas
will continue to range around 2-3 feet for much of the period,
with more normal shower and storm coverage forecast.

&&

.AVIATION...
(06Z TAFs)
Issued at 120 AM EDT Wed Jul 16 2025

VFR conditions continue outside of convection. Though Invest 93L
continues to pull away (W/NW) from ECFL, abundant moisture will
stream across the area in its wake. Light SE/S flow continues thru
early morning, with southerly flow dominating during the day on
Wed. Wind speeds increasing to 8-12 kts areawide, and a little
gustier across coastal TAF sites. A gradual return on this day to
the normal sea breeze regime, though highest PoPs look to favor
the interior and esp WCFL into late afternoon/evening. PoP
potential highest along the coast during the morning and early
afternoon. Too early for TEMPO groups, but do have some VCSH/VCTS
at various locations.

.SYNOPSIS...
Building heat and humidity continues this week, peaking
tomorrow, but possibly lasting into Thursday or Friday as high
pressure remains offshore. A cold front should bring showers and
thunderstorms Thursday and Friday before relief from the heat
arrives this weekend.

&&

.NEAR TERM /THROUGH TODAY/...
Key Messages:

* Isolated (a couple?) showers or garden variety thundershowers
along seabreezes thru sundown, but mainly dry weather for the
vast majority of Southern New England.

* Low clouds and fog return, similar to last few nights. Muggy
lows upper 60s to lower 70s.

Rather quiet weather continues into this evening. Mainly clear
to start, but already spotted fog and stratus forming off the
coast. Much like past night, this fog and stratus should reach
at least the coastal plains of RI and southeast MA. A light
southwest wind should limit the northward extend of this across
eastern MA. Thinking the I-90 is the northernmost limit. Low
clouds and fog could be farther north than that within the CT
River valley.

Minor tweaks to bring temperatures back in line with observed
trends.

Previous Discussion...

Remains a very warm to hot day across Southern New England, with
dewpoints in the upper 60s to low 70s leading to elevated heat
indices. First-order stations (ASOS METAR reports) have reported
heat indices in the mid 90s as of this writing, although the
usual variation exists comparing these to mesonet sites.
Although we are condtionally-unstable with sfc-based CAPEs in
the 1500-2000 J/kg range, lack of forced synoptic ascent and
weak capping have largely stunted any showers or thunderstorms
from popping up. There has been some showers along the CT-RI
south coastal seabreeze, and we could see a pop-up shower or
thunderstorm develop into the Merrimack Valley too due to the
seabreeze there and perhaps in/around the terrain. Other than
these mesoscale- driven areas, the vast majority of Southern New
England ends up being dry, so kept PoP at no worse than 20%
along the interior and along the south coast. Any shower or
thundershower activity which pops up will diminish after
sundown.

Aside from that though, the forecast for the evening should end
up being pretty similar to the last few overnights. Once the
sun goes down, stratus/mist re-develops and returns northward
from the southern coastal waters. Warm and humid evening with
lows upper 60s to lower 70s.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...
230 PM Update:

Key Messages:

* Hot, humid and dry Wednesday, the peak of the spell of heat
and humidity. High heat indices in the upper 90s to lower
100s.

* Increasing clouds, scattered passing showers with brief
downpours moving in during the second half of the overnight.
Hazardous weather isn`t expected. Very warm and muggy night
with lows in the low to mid 70s!

Details:

Hot and humid weather continues into Wednesday as well, as a
shortwave ridge briefly builds into Southern New England. In
addition to even warmer temperatures aloft, subsidence aloft
brought on by this shortwave ridge will serve to suppress any
diurnal showers or thundershowers despite otherwise ample
instability. Heat Advisory still remains valid, with air temps
in the low to mid 90s contributing to heat indices around the
upper 90s to lower 100s. Daytime seabreezes look to develop too,
but these won`t do very much at all to cut into the heat and
humidity.

Shortwave ridge axis pulls offshore during the mid afternoon
hours on Wed, and this will allow for a weak shortwave trough
now over the OH Valley to slowly progress ENE through the
northern mid-Atlc and Southern New England Wed evening.
Increasing cloud cover from both the coastal waters and from
interior western New England should keep temps warmer during the
overnight with lows in the mid 70s! The shortwave trough will
also bring with it a threat for showers or rumbles of thunder;
with PWAT values on the rise to nearly 2" per SREF mean output,
brief downpours can`t be ruled out but the coverage of showers
may end up being more scattered and those that do develop should
be moving along. Given those factors, we are not expected to
see the really high rain rates/heavy rain footprints like we saw
during the early morning hours late last week.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Key Messages:

* Heat and humidity persists into Thu or Fri with increasing
chances of showers/storms.
* Relief arrives this weekend.

We remain in hot/humid airmass through end of this week,
awaiting approach of mid level short wave and fairly strong
cold front which will eventually bring relief from the heat and
humidity this weekend. Not seeing large timing differences with
this cold front passage, which should be sometime Thursday night
into Friday morning. Larger timing differences are present with
this front when it likely returns back as a warm front Sunday,
then moves offshore again as a cold front Monday.

Still thinking Thursday is the day with the greatest risk for
afternoon and evening showers and thunderstorms. Given the heat
and humidity expected to be in place, a few thunderstorms
could produce strong winds. The greater concern remains the
possibility for downpours and localized flooding. Friday and
Saturday have trended more rain-free behind the aforementioned
cold front. Then had to mention more showers Sunday into Monday,
although confidence in the timing is rather modest.

&&

.AVIATION /05Z WEDNESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

High confidence.

Low clouds and fog will bring IFR/LIFR conditions to much of
South Coast, Cape Cod, and Islands through sunrise, possibly
advancing into NE CT and most of RI/SE MA. These lower ceilings
will retreat southward after sunrise leaving VFR conditions by
early afternoon, but will then return around sunset and persist
tonight once again with widespread IFR/LIFR into Thu morning.

Otherwise, VFR with S/SW winds through tonight. Gradient remains
weak enough to allow for sea breezes along E MA coast for a time
later this morning into early afternoon, before S winds return.

Later tonight, areas of MVFR ceilings develop with showers
possible in western New England overnight, perhaps spreading
into more of southern New England Thu morning. Conditions then
improve again to VFR but we may see a round of showers/storms
later in day, especially in western MA/western CT.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday Night: VFR. Breezy. Slight chance SHRA.

Weak low pressure center will continue to move westward across the
Florida Panhandle through tonight, which will continue a moist
south to southeast flow across NE FL/SE GA. This will allow for
the East Coast sea breeze to push inland to the US 301 corridor,
then interact with the lingering tropical moisture in place across
NE FL where PWATs will remain above 2 inches and expect numerous
to widespread showers and storms again this afternoon/evening,
with heavy rainfall the main threat, although a few isolated
strong to severe storms with gusty winds to 40-60 mph will still
be possible, along with some weak rotation possible in some of the
more intense storms since area will remain on the East side of the
departing low pressure system. Slightly lesser convection expect
along the NE FL coastal areas and across SE GA, where scattered
showers and storms are expected. Max temps should rebound into the
lower 90s over inland areas and upper 80s/near 90F along the
Atlantic Coast, and dew points temps into the mid/upper 70s will
still push Heat indices to 100-105F, but still below heat advisory
criteria. Convection will linger over inland areas along the I-75
corridor through the evening hours with heavy rainfall threat
until midnight, then just a few isolated showers possible during

Issued at 1246 AM EDT Wed Jul 16 2025

High pressure will build to the east Thursday, with ridge extending
across forecast area. The ridge will move toward the southeast

.LONG TERM...
(Saturday through Tuesday)
Issued at 1246 AM EDT Wed Jul 16 2025

The region will be between high pressure to the southeast, and the
trough across the southeastern US over the weekend into early next
week. A moist flow from the southwest will keep chances for mainly
diurnal precipitation in the forecast.

An elongated area of low pressure may develop along the southeastern

.AVIATION...
(06Z TAFS)
Issued at 1246 AM EDT Wed Jul 16 2025

South to Southeast winds will continue at 5-10 knots this morning,
and with the moist airmass will need to keep at least VCSH at the
regional terminals with rainfall chances in the 10-20% range
through the morning hours, along with TEMPO MVFR CIGS at times.
Diurnal heating today will allow for scattered showers to develop
for coastal terminals later this morning and will need to keep
PROB30 groups at CRG/JAX for TSRA during the 16-20Z time frame,
while much higher rainfall chances at VQQ/GNV as the East Coast
sea breeze pushes slowly inland triggers numerous TSRA and expect
to need TEMPO groups from the 18-22Z range at VQQ and 20-24Z range
for GNV. Convection will fade at coastal TAF sites towards the end
