.UPDATE...
Issued at 719 AM EST Tue Nov 18 2025

No significant changes to the forecast this morning. Very patchy
fog inland this morning will linger through the next hour or so
before dissipating, with an overall mostly sunny and pleasant day
with mild high temps in the mid/upper 70s to low 80s.

&&

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

Calm conditions exist behind yesterday morning`s frontal passage.
Not a significantly dry airmass and there is enough near-ground
moisture in place to allow patchy to areas of fog to develop, mainly
across NE FL this morning. Some patches may become dense at times,
especially around sunrise. Fog that forms should lift quickly this
morning.

Surface ridging moving off the Mid Atlantic coast today will direct
flow onshore today. Within that onshore flow, a weak inverted trough
will develop and potentially provide enough convergence to trigger a
few showers, which should stay offshore and over the waters for the
most part with only stratocumulus being pushed inland.

Tonight, a bit of moistening under the influence of another area of
high pressure consolidating over the northern Gulf coast. The
combination of the moistening and calm conditions will lead to
another potential fog event Wednesday morning with a broadened
concern area for dense fog development. Dirty ridging moving in from
the west will stream cirrus in overhead which may limit fog extent.

Comfortable temperatures today after a cool start in mid 40s to low
50s this morning, inland temperatures will rise to the low 80s (only
a few degrees off from daily records - see CLIMATE section for
details). At the coast the onshore flow will lead to cooler
conditions with highs in the mid/upper 70s.

&&

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

Dry weather conditions will continue after midweek as high
pressure over the forecast area shifts further towards the east
and allowing for more humid air to settle in over the region.
Potential for overnight and early morning fog developments through
Thursday. Daily high temperatures may potentially challenge record
high levels for the period as max temps rise in the lower to mid
80s. Overnight low temperatures will range between the lower to
mid 50s for inland areas and in the lower 60s along the coastline.

&&

.LONG TERM...(Friday through Monday)

Showers and possible thunderstorms are expected to build across
inland southeast Georgia and into northeast Florida along and
north of the I-10 corridor on Saturday as high pressure ridging
over the region moves off to the southeast into the Atlantic and
instability ahead of an advancing cold front. Dry weather
conditions will return by the end of the weekend and into next
week as dry air following the frontal passage settles in over the
forecast area. Temperatures will experience a slight cooling trend
going into the weekend and into next week, however temps are
expected to remain above the seasonal average throughout the
period.

&&

.AVIATION...
(12Z TAFS)
Issued at 719 AM EST Tue Nov 18 2025

Very patchy MVFR fog could briefly affect inland areas through
about 13-14Z, but otherwise no significant operational concerns
expected through this evening. Some scattered Cu will stream
towards this coast most of today, though not expecting any ceiling
restrictions at this time. Fog potential is expected to be higher
early Wednesday Morning, and will iron out more details as we get
closer.

&&

.MARINE...

There will be a weak and brief coastal trough over the waters
which may lead to isolated showers off the northeast Florida coast
through the afternoon and evening before lifting away to the
northeast. Otherwise, high pressure will be the dominant weather
feature through the end of the week resulting in light winds and
low seas across the local waters. Over the weekend winds turn
offshore and become breezy as a cold front approaches and passes
Sunday night. High pressure building in behind the front will move
offshore to the northeast early next week setting up onshore flow
and development of a coastal trough.

RIP CURRENTS: A low-end Moderate risk is expected today due to
onshore flow. A Low Risk is anticipated Wednesday through the
weekend.

&&

.FIRE WEATHER...

Drier air over the forecast area will result in MinRH values in
the lower 30s over inland southeast Georgia today, however low
wind speeds today will keep conditions from reaching elevated fire
danger levels. The mild and variable winds through today will
result in lower mixing heights and poor daytime dispersion values.
MinRH values will gradually rise as the week progresses, however,
poor/fair dispersions and dry weather will persist through Friday.
