.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
This afternoon...Pre-frontal band of showers still on track to push
through SE GA early this afternoon and through NE FL during the mid
to late afternoon hours, still expecting these to mainly be on the
light to moderate side with 50-70% coverage across SE GA and 30-50%
coverage across NE FL. Westerly winds will slowly become near breezy
around 15 mph with a few gusts to 20-25 mph expected. Max temps only
in the 50s across SE GA with lower/middle 60s across NE FL.

Tonight...Following a brief lull in shower activity this evening,
the trailing strong cold frontal passage on track after midnight
will trigger another round of shower activity across NE FL, mainly
south of the I-10 corridor, with best chances of measurable rainfall
south of a line from Gainesville to St. Augustine, but still overall
rainfall amounts expected to be a 0.10" or less. Main story will
still be the wind shift to the Northwest following the frontal
passage during the overnight hours with much colder and drier air
mass pushing into the region. Northwest winds will increase to
around 15 mph with gusts of 20-30 mph at times. Low temps will fall
into the 30s from the I-10 corridor northward across all of SE GA by
sunrise, but a freeze is not anticipated at this time and likely too
much wind for any frost formation. Across the rest of NE FL min
temps will fall into the lower/middle 40s. The main impact around
sunrise Thursday morning will be the wind chills which will fall
into the 20s for SE GA and 30s for NE FL, but will remain above Cold
Weather Advisory criteria for early Thursday morning.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
Dry and cold air filters into the region through the end of the week
after the passage of a cold front on Thursday. High pressure builds
over the region behind the front, sitting overhead by Friday.

Thursday...A cold front pushes into and across the region during the
predawn hours, clearing to the south by the early morning hours.
Behind the front, cold and drier air push in as breezy northwesterly
develop. Clearing skies and cooler air, will bring daytime highs in
the mid 40s to lower 50s for locations north of the I-10 corridor
and across SE GA, with lower to upper 50s across inland NE FL and
coastal locations. High pressure begins to build over the region
Thursday evening, with winds beginning to taper off and becoming
near calm sometime around midnight. A Freeze Watch is in effect area-
wide as temperatures are expected to crash to drop to sub-freezing,
with inland lows in the lower to mid 20s and the lower 30s along the
coast. With the near calm winds, frost development is likely to be
widespread with patchy frost along the coastal locations. Issuance
of a Cold Weather Advisory may still be needed, but will hold off
for now with this forecast package.

Friday...High pressure will be centered over the area, with calm to
light southwesterly winds expected through the day. The dry and cold
conditions continue, but temperatures will be warmer than Thursday
as daytime highs will be in the 50s area-wide, with warmer
temperatures over NE FL. Overnight lows in the 30s area-wide. Near
winds along inland locations could see some patchy frost during the
overnight hours into Saturday.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
High pressure pushes off towards the Atlantic as the next cold front
shifts towards and crosses the region on Saturday night. With
southwesterly flow in place after the last frontal passage, warmer
temperatures on Saturday with highs in the 60s area-wide, with a few
locations crossing into the 70s across north central FL. With
lingering moisture over the area, will likely have isolated to
scattered showers develop for locations north of the I-10 corridor
and across SE GA ahead of the front late Saturday afternoon to
Sunday morning. Will note that some guidance is suggesting a
rain/snow mix with the passing showers on Saturday night. For now,
just put in a mention of a small chance of any wintry mix during the
overnight hours, but will likely see this change as we get closer to
this weekend as the weather pattern develops. Otherwise, dry
conditions make a return to start the upcoming week as high pressure
builds in behind the front, with chances for frost and freeze
products returning heading into the upcoming week.

&&

.AVIATION /00Z THURSDAY THROUGH 00Z FRIDAY/...
West-southwest winds will decrease to around 5 kts tonight with VFR
conditions continuing through 06Z. A cold front will move through
the TAF sites from 06-09Z with a few showers passing by the NE FL
sites during this time. MVFR ceilings develop behind the frontal
passage in the 09-12Z time frame but should lift to VFR by 15Z.
Breezy northwest winds develop after 12Z with sustained winds
10-15 kts and gusts 20-25 kts.

&&

.MARINE...


Caution level westerly winds offshore continue this evening ahead of
an approaching cold front. A few showers will move across the waters
tonight. The cold front will cross the waters late tonight into
early morning, with a return of small craft advisory conditions as
breezy northwesterly winds develop in its wake. Small craft
conditions continue through Thursday night with occasional gusts
near gale force. 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 with a brief period of small craft advisory
conditions possible.

Rip Currents: SE GA Low Thursday
              NE FL Moderate Thursday

&&

.FIRE WEATHER...
- High Daytime Dispersions Thursday And Sunday
- Low Dispersion North-Central Fl Friday

Breezy northwesterly surface and transport 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. High
pressure overhead Thursday night shifts southward Friday into
Saturday. Low dispersions will be possible across north-central
Florida on Friday. Another front will move through the area Saturday
night into Sunday bringing the potential for another round of
isolated to scattered showers.

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 to widespread frost. A light inland
freeze will be likely each night for several nights beginning Friday
Night.
