.NEAR TERM /THROUGH TONIGHT/...

Mostly clear skies today will allow temps to warm into the low
to mid 60s across NE FL and the mid and upper 50s for SE GA this
afternoon despite the cooler, drier air gradually funneling in
behind this early morning`s front passage.

Tonight, clear and calm conditions will allow for excellent
radiational cooling with light freezing conditions likely for the
Suwannee Valley and interior SE GA. There will also be areas to
widespread frost for interior areas from Gainesville north and
possibly as far east as the west side of Jacksonville. There is a
Freeze Warning and a Frost Advisory in effect and have been
unchanged.

Though the airmass will be dry, given the excellent cooling and
lingering ground moisture from last weekend`s wet weather, patchy
shallow ground fog may develop especially in open fields. Lows
tonight will be the low to mid 30s for inland areas and low 40s at
coastal locations.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...

Surface high pressure slides east of our area on Friday and
further into the Atlantic on Saturday as mainly zonal flow aloft
persists. Mainly weak flow in the low levels will continue through
the short term as a result of the weak high/weak pressure gradient
influence, with dry and close to seasonal temperatures and more
sunshine than clouds, especially on Friday. Highs on Friday will be
in the mid 60s north to lower 70s south, warming up a bit more for
Saturday to the upper 60s north and low to mid 70s south. Widespread
lower to mid 40s expected Friday night with good radiational
cooling, and just a few degrees warmer Saturday night as low level
winds come around to southwest and increase slightly ahead of the
next cold front. Just enough pooling of low level moisture may also
result in some patchy fog inland areas around the Suwannee Valley
early Saturday morning and across much of interior northeast FL
early Sunday morning with the light southwest flow off the Gulf.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...

Cold front approaches the area by Sunday Morning, progressing
southeastward throughout the day and into the night. Tight surface
pressure gradient will bring breezy conditions Sunday Night and
Monday after the front moves through, as well as another shot of
very cool and dry conditions with temps around 15-20 degrees below
normal by Monday. Rain chances look to be low overall at this time
with the frontal passage, though the highest probability of a
isolated to scattered shower Sunday afternoon and evening will
likely be over interior GA. Cool to cold conditions will be fairly
short lived however as the associated surface high quickly moves
northeast of the area Tuesday and into the Atlantic for midweek.

Cold conditions behind the front will bring a potential for
freeze/hard freeze away inland the further north and west you go
Sunday Night into Monday Morning, though frost will be quite patchy
due to the breezy conditions. Similar potential will be expected for
Tuesday Morning as well, with areas of frost also expected to be
more common as winds relax Monday Night. Both max and mix
temperatures trend upward Tuesday and into mid week as the airmass
moderates.

&&

.AVIATION /18Z THURSDAY THROUGH 18Z FRIDAY/...

VFR conditions are expected with light northwesterly winds trending
calm overnight. Shallow ground fog may develop and KGNV and KVQQ
during the predawn hours but confidence to low to include at this
time.

&&

.MARINE...

Lingering winds behind a dry frontal passage will continue Small
Craft Advisory conditions offshore through the rest of the morning.
A high pressure center will build into the area today into Friday
and then shift offshore by early Saturday ahead of the next frontal
boundary. This next front will likely remain dry as it crosses our
local waters on Sunday night. Strong, arctic high pressure building
behind this frontal passage will result in strong northerly winds on
Sunday night that will shift to northeast on Monday. Small Craft
Advisory conditions with potential for Gale-force gusts throughout
our local waters from Sunday night through Monday night.

Rip Currents: SE GA Low Friday
              NE FL Low Friday

&&

.FIRE WEATHER...

Fair to good dispersions will be expected for the rest of the
daytime today with modest low level winds behind a passing cold
front. Remaining dry as well, though minRH values are expected to
remain well above any critical levels. High pressure moves almost
directly overhead tonight and through Friday, which will result in
lighter winds and therefore poor to fair dispersions Friday
afternoon/evening. Winds shift more south to southwesterly this
weekend with warmer but dry conditions before a front moves through
Sunday Night, ushering in another drier and even cooler airmass for
early next week. Rain chances are low at this time with the front,
and best chances for showers will be over inland GA Sunday
afternoon/evening.

FOG POTENTIAL AND OTHER REMARKS: A light freeze possible for inland
southeast GA and the Suwannee Valley for Friday morning. Patchy fog
possible for inland areas late Friday night and again Saturday night.
