Near term tonight through Saturday ...

a 1029 mb high pressure ridge located from al to north central fl
will continue to support light winds rest of today with light
winds and abundant sunshine. Temps remain cooler than normal with
very dry air and dewpoints below 20 in many areas at this time.

With clear skies tonight, except for a few cirrus clouds, temps
will drop quickly into the upper 30s to near 40 by the mid to late
evening hours. Used a blend of guidance for lows with a freeze
expected over inland areas. Have issued freeze warning and frost
advy for parts of northeast fl. Only light wind from drainage
flow from the west and northwest.

Saturday... After a cold start... Temps will continue to rebound
closer to normal afternoon highs under prevailing low level flow
from the westerly direction near 5-10 mph. Mostly sunny except for
increased mid to high clouds streaming in on west-southwest flow
aloft. Highs fcst mainly lower-mid 60s north zones to mid-upper
60s southern parts. Notable exception for a bit cooler MAX temps
is along the coast as weak onshore flow develops in the aftn.

Water temps noted to be in the 50s to a few upper 40s with the
cold snap we have had.

Short term Saturday night thru Monday night
Sat night thru Sun night... At the surface, high pressure ridge will
extend from ga through the carolinas and into the WRN atlc while
aloft at 500mb a shortwave will track from the NRN gomex and
across NE fl SE ga on Sunday then offshore. For now it appears
that this shortwave will not have enough atmospheric moisture to
work with to kick off any shower activity there will be some
increase in cloud cover over the weekend mainly over the atlc and
ne fl portions. Overall the warming trend will continue with lows
in the upper 30s across SE ga and suwannee valley of north fl
while 40s expected elsewhere Sat night with highs rebounding to
near 70 degrees over inland areas Sunday afternoon while a cooler
developing onshore flow will keep the coastal counties in the 60s.

Continued onshore flow and low level moisture Sunday night will
keep lows generally in the 40s for SE ga inland N fl while lower
50s expected across coastal NE fl. Might be just enough low level
moisture for some patchy fog by early Monday morning but not
confident significant enough to place in forecast yet.

Monday Monday night... A rapidly weakening cold frontal boundary pushing
through the SE us will approach the region and southerly flow
ahead of this feature will warm most areas into the 70s with
cooler SE flow at the coast keeping the beaches in the 60s. A
slight chance of showers will push into inland SE ga late in the
day and into Monday night but models are in general agreement with
keeping measurable pcpn across SE ga and the suwannee valley of
inland north fl while keeping the rest of NE fl dry. Increasing
cloud cover will keep temps mild in the 50s Monday night across
all areas.

Long term Tuesday through Friday
Tue Tue night... Models trends are for mainly dry frontal passage across
the rest of the area on Tuesday pushing offshore Tue night with
rain chances generally 10% or less. Slightly cooler temps expected
with the frontal passage on Tuesday with highs in the 60s most
areas except near 70 degrees across inland NE fl. Cooler more
seasonable temps expected to return Tue night with lows near 40
across SE ga suwannee valley and in the 40s the rest of NE fl.

Wednesday... High builds north of the region with onshore NE flow
developing and while partly cloudy skies are expected, airmass
should remain too dry for any pcpn. Highs lows closer to normal in
the 60s 40s.

Thu fri... Model solutions continue to diverge at this point, but
overall pattern sets up with high pressure north of the region and
a moderate NE flow off the atlc which along with a possible
shortwave pushing across the region aloft will support at least a
slight chance of showers... Especially along the atlc coastal
counties and across NE fl as deeper moisture slowly increases
aloft from the W sw. Temps still fairly close to normal with highs
in the 60s near 70 and lows in the 40s 50s.

Aviation
Vfr with clear skies. Very shallow radiation fog smoke haze
possible late tonight early Saturday but too localized to include
in tafs. Light and variable winds expected.

Marine Strong high pressure centered over the gulf coast
region will slowly move east-northeast through the weekend.

Winds will be somewhat variable but generally 10 kts or less
through Saturday night. Slightly strong northeast to east flow
develops Sunday as the high pushes northeast of the region.

Southeast flow early next week as a weak cold front pushes into
the southeast u.S., with frontal passage over area waters on
Tuesday. Winds will be near scec conditions at times from Monday
night through Wednesday mainly over the offshore waters.

Rip currents: generally low risk given decreasing surf height of
about 1-3 feet and light winds through Saturday.
