Above normal near record temps continue with dense fog possible
inland late tonight...

Near term tonight-Friday
High pressure ridge at the surface aloft extends from the WRN atlc
across NE fl SE ga with E SE steering flow and well above normal
temps continuing. The moist low level airmass will continue to
support late night stratus fog, with the best chances of dense fog
over inland areas that cool below current dewpoints to around 60
degrees while a bit milder with lower middle 60s closer to the
coast with some lower stratus and lesser chances of fog. Some of
the hi-res models are starting to come into better agreement for
some sort of a coastal trof pushing up the fl peninsula late
tonight with some local showers being generated that will push
into the NE fl coastal region Fri morning with widely scattered
showers possible and a portion of this moisture will push into
inland NE fl and SE ga by the afternoon with some isolated showers
possible in the heating of the day as steering flow becomes a bit
more southerly. Definitely more clouds expected than previous days
but the southerly flow should continue to generate above normal
highs into the lower middle 80s inland and 70s along the coast.

Short term Friday night-Sunday night
Fri night-sat night... High pressure ridge will get shunted south
of the region down the fl peninsula and this will veer the
steering flow around to the SW and continue well above normal
temps into the 80s inland and mid upper 70s coast. Rain chances
will continue to remain minimal with chances less than 15% and
patchy areas late night fog is expected, some of which could be
locally dense.

Sunday-Sunday night... Weakening cold frontal boundary will track
across the SE us and slow down as it pushes into SE ga by Sunday
night. This will trigger scattered showers and isolated storms
across SE ga by late Sunday into Sunday night. Near record all-
time temps will be possible ahead of the front on Sunday afternoon
across the region with mid upper 80s possible over inland areas
and offshore SW flow will likely push the atlc coast into the
lower 80s as well.

Long term Monday-Thursday
Monday... Weakening frontal boundary will sag through all of se
ga NE fl with scattered showers and isolated storms possible.

Still some question as to amount coverage of rainfall as upper
level support for the front will be much less than over the
weekend. Temps will still be above normal but around 5-10 deg
cooler than Sunday ranging from the mid 70s across SE ga to the
upper 70s lower 80s NE fl.

Tue-thu... High pressure will build southward across the region on
Tuesday then south of the region on Wed Thu with long-range models
trying to shunt any of the mid-latitude energy NW and N of the
region for now with possible scattered showers pushing into SE ga
by Thursday and isolated showers across NE fl. Fairly low
confidence in the forecast by wed-thu time frame, but overall
expect temps to continue above normal for late february. Possible
cold frontal passage expected by Thu night-Friday time frame but
details still too fuzzy at this time.

Aviation
Vfr conditions dominate. Winds are from the east-southeast at 5-10
knots with some gusts over 15 knots. The winds will calm and the
cloud cover will gradually decrease during the evening hours.

Through the overnight, another period of low stratus and fog is
expected. With the persistent atmospheric pattern, expecting ifr
conditions for a few hours (11-14z) at inland TAF sites,
especiallygnv. Coastal sites such as kcrg and ksgj will see
primarily MVFR CIGS and vsbys. With the cooler ocean temperatures,
have ifr conditions for kssi as well. Stratus and fog will begin
to break around 14z as heating and mixing increases. Isolated
showers near ksgj tomorrow morning, but decided to keep it out of
the TAF for now.

Marine
Onshore E SE flow will continue in the 5-15 knot range with
elevated seas in the 3-6 ft range through Friday with scec
headlines for the higher seas close to 6 feet offshore. As high
builds further offshore flow becomes southerly over the weekend at
10-15 knots with similar seas continuing. Models agreeing on weak
front pushing across the coastal waters on Monday with winds
briefing reaching 15-20 knots with seas 3-6 ft, then high builds
north of the waters on Tuesday with becoming NE at 15-20 knots
with possible seas up to 7 ft and SCA headlines may be required.

Patchy areas of stratus fog still possible in the nearshore SE ga
waters tonight as higher dewpoints still override the cooler ocean
temps but they have continued to warm slightly over the past few
days.

Rip currents: moderate risk in the onshore flow.
