.NEAR TERM...
Issued at 1258 AM EST Wed Dec 11 2024

For the latest NE FL and SE GA Daily Key Messages please visit:
https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Prefrontal troughing will produce a few showers during the pre dawn
hours Today. Expecting a line of convection with embedded
thunderstorms along a cold front to enter inland SE GA right around
sunrise, then quickly move southeast across the forecast area during
the morning, clearing to the southeast early in the afternoon.

A few strong storms with gusty winds are possible with this line,
and an isolated severe storm can not be ruled out. High pressure
will build from the west later this afternoon following the front,
with good subsidence clearing skies from northwest to southeast.

Winds will be gusty Today, with gusts up to 30 to 35 mph. The best
chance for these higher gusts will be right along, and immediately
behind the convective line.

Temperatures will be non diurnal Today, with highs this morning, and
falling readings through the afternoon. Lows Tonight will fall into
the lower to mid 30s inland, upper 30s to around 40 coast. A
widespread inland Frost is expected. A few locations could touch
freezing inland. Headlining the Frost potential with an advisory.

&&

.SHORT TERM...
(Thursday through Friday night)
Issued at 1258 AM EST Wed Dec 11 2024

Thursday...Cold high pressure builds Northwest of the region
with sunny skies and below normal temps with highs in the
mid/upper 50s and North winds at 10-15G20 mph, mainly highest
at the Atlantic Coast.

Thursday Night...Cold High pressure builds north of the region
over the Carolinas with surface flow become Northeast and this
will lead to a slight moderation in temps with lows in the
lower/middle 30s over inland SE GA and the Suwannee Valley
with another light Freeze/Frost possible but chances not as
high as tonight. While along the Atlantic Coast and the rest
of NE FL expect onshore/NE flow at 5-10 mph will keep temps
elevated above freezing with no Frost expected as temps remain
closer to 40F.

Friday...High pressure remains anchored near the Carolinas as
Northeast winds increase across the region and become breezy
along the Atlantic Coast as temps modify and return closer to
normal levels with highs in the 60s across SE GA and near 70
across NE FL as cloud cover increases to partly to mostly
cloudy levels, but any isolated showers should remain over
the Atlantic Coastal waters.

Friday Night...High pressure drifts off the Carolina Coast as
surface flow remains E-NE at 10-15 mph along the the coast and
around 5 mph inland, but high enough to keep temps well above
freezing with lows in the 40s inland and 50s along the Atlantic
Coast and once again any isolated shower activity should remain
over the Atlantic Coastal waters.

&&

.LONG TERM...
(Saturday through Tuesday)
Issued at 1258 AM EST Wed Dec 11 2024

Saturday...High pressure remains anchored off the Carolinas with
E-NE flow across the area with temps near normal levels under
partly to Mostly cloudy skies and while some moisture will
increase aloft, still expect rainfall chances will remain around
20 percent or less and mainly over the Atlantic Coastal waters.

Sunday...Weak trough pushes through aloft early Sunday and brings
drier air aloft as high pressure remains in place across the SE
US states with surface winds becoming more North at 10-15G20 mph
through the day with mainly dry conditions and temps remaining
close to normal levels.

Monday...No change in local pattern as weak high pressure remains
in place with weak north flow at the surface and temps remain
close to normal levels with mainly dry conditions.

Tuesday...Weak frontal boundary approaches the region from the NW,
but will likely end up as a dry frontal passage by Tuesday night
and expect temps to push to slightly above normal levels, but no
rainfall is expected at this time.

&&

.AVIATION...
(06Z TAFS)
Issued at 1215 AM EST Wed Dec 11 2024

Ceilings will lower this morning, with restrictions expected
throughout the day. Visibility restrictions will be expected late
this morning through mid afternoon as a line of showers with
embedded thunderstorms passes through with the cold front. Gusty
winds are expected to develop this morning, and continue through
the afternoon, then subside this evening. A few strong storms
possible.

A period of Low Level Wind Shear is expected early this morning.

&&

.MARINE...
Issued at 1258 AM EST Wed Dec 11 2024

A cold front will move southeast across the area early Today. High
pressure will build from the west this afternoon through Tonight.
The high will build to the northwest then north Thursday. The high
will build to the north northeast Friday through the weekend with
an inverted trough developing over the coastal waters. High pressure
will build overhead of the region early in the week.

Rip Currents: Moderate through Thursday
