.NEAR TERM /THROUGH TUESDAY/...
Cold front will move to the southeast of the area this evening, with
strong high pressure building from the northwest. Winds will remain
gusty this evening then begin to diminish during the overnight.
Skies will decrease in coverage from northwest to southeast Tonight.
The cold airmass will begin advecting into area Tonight. An inland
Freeze is expected Tonight. A few locations over Suwannee valley of
NE FL could reach cold advisory criteria, but should be brief and
very localized. So at this point focusing on the Freeze Warning
headline, and holding off on cold weather advisory.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Much drier, cooler air will be present Tuesday following the cold
frontal passage, with northwesterly winds bringing in PWATs near 0.2
inches. High temperatures will not break 60 degrees for the area,
with portions of inland southeast Georgia remaining in the upper
40s. Tuesday night will be cold, with lows dropping into the mid 20s
to near 30 inland, and lower to mid 30s along the coast and St.
Johns river basin area. A Freeze Watch is now in effect for all
inland locations, as well as the southeast Georgia coast Tuesday
night into Wednesday morning. Apparent temperatures will drop into
the 20s for most locations, the need for a Cold Weather Advisory
(Wind Chills 15-20 degrees for SE GA and 20-25 degrees for NE FL)
will be evaluated tonight. With pretty calm winds overnight, frost
is likely to develop nearly area-wide, excluding the immediate coast
and St. Johns river basin.

Wednesday will warm up a little bit, but highs will remain in the
mid to upper 50s with sunny skies and northwesterly to westerly
winds. Again, lows will dip into the 30s area-wide with frost
formation likely and a light freeze possible for portions of inland
southeast Georgia and northeast Florida.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
It will continue to gradually warm up Thursday through the weekend
with highs in the mid 60s to low 70s and dry conditions expected
Thursday and Friday. A front will approach from the north on Friday
night, bringing showers and isolated thunderstorms beginning after
midnight for southeast Georgia, lasting through sunrise Sunday over
land. Thunder chances are generally low, with the best shot at
thunder being Saturday afternoon for southeast Georgia and the
Suwannee Valley. Skies will clear out throughout the day Sunday with
highs near average.

&&

.AVIATION /00Z TUESDAY THROUGH 00Z WEDNESDAY/...
After brief restrictions for MVFR/IFR ceilings at the northeast
florida terminals through 02Z, VFR conditions will resume at all
sites as a cold front exits southeast of the area this evening.
Winds from the west will become northwesterly 10-15 knots with
gusts 15-20 knots through 06Z. Winds remain from the northwest
Tuesday around 8-10 knots with scattered mid and high level
clouds as high pressure builds in from the west northwest.

&&

.MARINE...


A cold front will move southeast of area waters this evening, with
strong high pressure building behind it. Conditions will be elevated
into Tuesday, due to gradient between front and building high. The
high will remain centered to the west through Wednesday, then build
overhead Thursday. The high will move off to the southeast Friday,
as an area of low pressure gathers over the northwestern Gulf. An
area of low pressure will move over region over the weekend.

Rip Currents: SE GA Moderate Tuesday
              NE FL Moderate Tuesday

.FIRE WEATHER...
     HIGH NIGHTTIME DISPERSION MONDAY NIGHT...

     MINRH VALUES IN THE 20S INLAND TUESDAY AND WEDNESDAY...



Northwesterly winds develop tonight through Wednesday which will
allow for much cooler and drier air to work into the region. Min RH
values drop into the low 20s to low 30s for inland locations on
Tuesday/Wednesday with good dispersion values expected.

FOG POTENTIAL AND OTHER REMARKS: A freeze is expected over inland SE
GA and near I-10 tonight into Tuesday morning. Another freeze is
expected Tuesday night into Wednesday morning with widespread frost
formation for inland areas.
