Info SPS Special Weather Statement — Tue Dec 25, 2018 2:24 AM

SPSJAX) should
be enough to cover the patchy/shallow nature of the fog. Otherwise
another Mostly Sunny to Partly Cloudy day expected with some high
cirrus expected from time-to-time after any fog dissipates by the
mid-morning hours. Seasonable temps continue with highs generally
in the 60s and near 70 across Marion County.

Tonight...Surface High pressure builds towards the Carolina coast
and down the SE US coastline while coastal trof starts to develop
further offshore in the NE FL Atlc Coastal Waters, this may
trigger a few isolated showers late tonight well offshore.
Otherwise generally partly cloudy skies as more high clouds
expected from the West which will thicken a bit overnight. Cool
surface conds this evening after sunset will support some more
patchy fog development by midnight with some dense fog possible
but will depend on cloud cover and coastal trof development
offshore which may tighten the pressure gradient slightly
overnight. Min Temps still near seasonable levels in the 40s
inland and near 50 degrees along the coast.

.SHORT TERM /Wednesday-Thursday night/...

High pressure strengthens across the mid Atlantic region
on Wednesday and strengthens further across northern
New England Thursday before moving east Thursday night.
A closed low across the lower Plains opens up and lifts
to the northeast which will drag a surface low to across
the western Great Lakes by Thursday night. Onshore flow
begins to increase on Wednesday as a coastal trough develops
which may produce a few coastal showers but otherwise dry
elsewhere with deep layer ridging in the area. A warm front
will approach the the area Thursday and be north of the area
Thursday night. The return of moisture with the approaching
warm front and veering flow to the Se will lead to a chance
of showers across the region with best chances across the
far Northwest zones where best moisture return and lift
will be. The veering wind will also lead to a warming trend
with temps above normal most areas by Thursday.

.LONG TERM /Friday-Monday/...

A cold front will approach but stall just NW of the region
through the weekend as it loses upper support. A moist and
unstable south to southwest flow out ahead it in combination with
mid level impulses will lead to scattered to numerous showers and
isolated storms with best chances area wide on Friday with the
front stalled just to the north. The frontal boundary pivots north
over the weekend as a deep layer ridge builds across south Fl and
Gulf resulting in continued good chances of showers and isolated
storms across the lower Suwannee Valley into inland Se Ga with
slightly lower pops elsewhere. Differences continue to exist
between the GFS and ECMWF especially early next week in regards to
the frontal position and timing and strength of mid level
impulses. Will continue rain chances into early next week. Temps
will warm to well above normal most areas at least into the
weekend.

.AVIATION...
Patches of shallow LIFR/VLIFR fog at VQQ/GNV/JAX/CRG this morning
while coastal TAF sites just have some MVFR/VFR fog towards
sunrise. Low fog conds will continue until the 13-14z time frame
before lifting to VFR conds with light winds and a few high
clouds. A return to some patchy fog with MVFR vsbys possible again
tonight after 03z.

&&

.MARINE...
Onshore N-NE flow will slowly increase to 15 to 20 knots by
Wednesday as High Pressure builds north of the region with a slow
building of seas to 3-5 ft by Wednesday as well. As the high
pressure builds offshore the gradient will continue to slowly
tighten with SE winds increasing to 15-25 knots on Thursday then
becoming South on Friday. Small Craft Advisories are expected to
develop by early Thursday and continue through the end of the
week.

Rip Currents: Northeast flow develops today but remains light so
will continue Low Risk, but Moderate risk expected as onshore flow
increases on Wednesday.
