&&

.NEAR TERM /THROUGH TONIGHT/...
Weak high pressure ridge will be over the region Tonight. Dewpoints
over the coastal waters will rise to levels that will be at or above
the water temperature. This setup will lead to fog development after
sunset along the coast, with this fog spreading inland through the
night. Beach front communities could have low vislibilities
beginning as early as sunset. Dense fog advisories may become
necessary, especially for coastal counties.

Lows will trend above seasonal averages Tonight.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
High pressure over the area begins to shift away from the FL
peninsula on Friday as a frontal boundary begins to push towards the
southeastern CONUS. The frontal boundary pushes into the area
on Saturday.

Lingering fog along coastal locations will begin to lift and clear
by the mid morning hours on Friday. The persistent southwesterly
flow ahead of the front will continue to bring in moisture from the
and warmer temperatures across the area on Friday. There will be an
increase in cloud cover compared to the past couple of days. Friday
daytime highs will again reach into the low and mid 80s across
inland locations, while upper 70s along the coast as a weak sea
breeze develops during the afternoon hours. Overnight lows in the
mid to upper 50s across inland locations and the lower 60s along the
coast.

Another night of patchy to areas of fog will be in Friday night as
lingering moisture from the Gulf will allow for some fog to develop
along the I-75 corridor during the early predawn hours on Saturday,
with some locally dense fog. Southwest winds will steadily shift to
be northwesterly during the overnight hours into Sunday.  A similar
spread of daytime temperatures compared to Friday with highs in the
lower to mid 80s. With the cold front pushing through, overnight
lows will be cooler across SE GA locations with lows in the mid to
upper 50s and lows in the lower 60s across NE FL.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Frontal boundary will clear the area on Sunday. Winds shift to
become northeasterly behind the front. Highs on Sunday will mostly
be in the upper 70s for most locations, with lower 80s along the I-
75 corridor. The northeast to easterly onshore flow will shift to
become southwest-southerly during the start of the next week as high
pressure centered over the Carolinas extends south towards the
southeast CONUS. Guidance is indicating the next frontal boundary to
arrive towards the local area by midweek of the upcoming week as the
high pressure moves off towards the Atlantic sometime on Tuesday.
This front could bring some showers over SE GA and south towards
locations along the I-10 corridor in NE FL Wednesday morning.
Otherwise, fog development will continue to be of concern during the
upcoming week as moisture continues to be brought into the area due
to the southerly flow.

&&

.AVIATION /12Z FRIDAY THROUGH 12Z SATURDAY/...

Morning fog will slowly lift this morning. Prevailing VFR
conditions will then be expected from mid morning through the
evening. Patchy fog will develop Tonight, which may lead to
diminished visibilities at area TAF sites.

&&

.MARINE...

Weakening high pressure will continue to shift slowly southeastward
across the Florida peninsula through Saturday. Dense sea fog is
expected to develop early this morning across the Georgia waters,
with this fog potentially extending to the near shore waters
adjacent to coastal northeast Florida before dissipating by early
afternoon. A weakening and mostly dry frontal boundary will then
push southward through the Georgia waters on Saturday night, with
this boundary pushing across the northeast FL waters early on Sunday
morning. High pressure will build eastward from the Ozarks on Sunday
towards the Mid-Atlantic states by Monday afternoon, with breezy
onshore winds developing across our local waters from Sunday
afternoon through Monday afternoon. A stronger cold front may then
push eastward across the southeastern states on Wednesday and
Wednesday night, with southerly winds expected to develop ahead of
this front beginning on Tuesday evening.

Rip Currents: SE GA Low Saturday
              NE FL Low Saturday

.FIRE WEATHER...
...LOW DISPERSIONS TODAY AT THE COAST AND NORTH-CENTRAL FL..

Another warm and dry day is in store today as high pressure
gradually retreats. Breezy southwesterly winds develop across inland
southeast Georgia this afternoon ahead of an approaching front.
Dispersions today will range from fair in southeast Georgia to low
at the Atlantic coast and north-central Florida. Breezy
southwesterly winds will spread across the entire area on Saturday
as the aforementioned front pushes southeastward into and through
the region overnight Saturday into Sunday. This will lead to good
daytime dispersions area-wide and an increase in low level moisture.
Unfortunately, this frontal passage will lack any much needed
rainfall for the area suffering from severe/extreme drought
conditions. Northeasterly winds behind the front Sunday will trend
easterly by Monday.

FOG POTENTIAL AND OTHER REMARKS...Patchy to areas of fog are likely
this morning and Saturday morning. Dense fog will be focused along
the I-95 corridor this morning and I-75 corridor Saturday morning.
