.NEAR TERM...(Today and Tonight)...

A slowing cold front is pushing through southern GA and will
continue to sink southward through the NE FL during the rest of the
morning. Like last night, the primary weather challenge will be
areas of dense fog development during the predawn hours. Moisture
pooling ahead of the front will lead to patchy fog development for
areas south of I-10 this morning with dense fog potential highest
(40-60%) across Marion, Alachua, and Putnam counties. This will
likely will require a Dense Fog Advisory for those areas later on in
the morning.

Much drier air will filter in behind the front today, pushing
humidity to low levels across SE GA and elevating wildfire danger
(more in the fire weather section below). That dry air will also
lead to mostly sunny skies today and clear skies tonight as high
pressure settles just to the north. Light onshore winds will keep
the coast cooler today and warmer tonight. Lows at the coast will be
in the upper 50s to near 60 degrees while inland lows will feel the
chill behind the frontal passage with readings in the low/mid 40s
common from the Suwannee Valley northward into SE GA, possibly even
touching the upper 30s again. Drier air should limit much in the way
of fog formation early Tuesday morning.

&&

.SHORT TERM...(Tuesday through Wednesday night)

High pressure ridging from out of the west will build in on
Tuesday and Wednesday over the region resulting in a continuation
of dry weather conditions with mostly clear skies and mild winds.
Potential for overnight and early morning fog developments through
the period. High temperatures will be within the upper 70s and
lower 80s through midweek with overnight low temperatures ranging
between the lower to mid 50s for inland areas and in the lower 60s
along the coastline.


&&

.LONG TERM...(Thursday through Sunday)

Dry weather conditions will continue through the end of the week
with a potential for showers on Saturday, primarily over inland
southeast Georgia, as high pressure formerly building over the
region moves off to the south and east establishing a more
southwesterly flow ahead of an advancing frontal boundary pressing
into the forecast area from out of the northwest. Temperatures
will remain above the seasonal average, nearing daily record
highs, for the end of the week and through the weekend.

&&

.AVIATION...(06Z TAFS) Issued at 1235 AM EST Mon Nov 17 2025

A dry cold front will move through the region this morning.
Patchy dense fog is expected to develop ahead of this front at
terminal south of I-10. KGNV, KVQQ, and KSGJ may be impacted by
fog at IFR to LIFR levels between 09z-12z this morning. Despite
the frontal passage, winds will be light given weak gradients with
incoming high pressure behind the front. There will be a shift to
the northeast with peak sustained winds around 8-12 knots with
the the high-end of that range at coastal terminals.

&&

.MARINE...

Winds will turn onshore and trend lighter today leading to fair
maritime conditions under the influence of high pressure which will
continue throughout the week. A southerly wind shift followed by a
shift to offshore flow will take place later this week as the high
pressure ridge axis moves south and cold front begins to sharpen
well to the west. The southerly flow will push warm, moist air
across the waters which may lead to patchy marine fog in the
nearshore waters to end the week. The aforementioned sharpening
front may move through the waters as early as Sunday morning but
more likely to pass next Monday.

RIP CURRENTS: Though winds will trend onshore, elevating risk, low
surf heights will keep risk toward low-end of Moderate today and
Tuesday.

&&

.FIRE WEATHER...

Dry air following the frontal passage will settle in over the
region bringing minRH levels down into the 20s and lower over
inland southeast Georgia and inland portions of northeast Florida
north of I-10. Winds will remain mostly mild and variable through
the day resulting in lower mixing heights and poor daytime
dispersion values. Conditions will be borderline today for
elevated fire danger, especially for areas near and north of
Waycross, however the low wind speeds will hold the product off
from being issued. MinRH values will rise as the week progresses,
however dry weather will persist through Friday.
