Some ice pellets possible over southeast georgia tomorrow...

Hard freeze watch for Wednesday night...

Short term
Tonight... A dry cold front will be moving across the area
overnight with low cloudiness and some light precipitation
developing over the northwest portions of the area in the wake of
the front. This should generally be north and west of highway 84
with a light cold rain and possibly some mixed in ice pellets
possible in that area toward sunrise. Looking at the model
soundings for that area not anticipating at any frozen
precipitation just the possibility of some freezing just above the
ground.

Wednesday... Same story up in the northwest counties of our area
some light rain with a few ice pellets will be possible through
the morning and early afternoon. Precipitation amounts will be
light in the .02-.05 inch range for liquid precipitation so not
expecting any significant freezing on the ground. Can't totally
rule out some very light freezing on bridges and overpasses but
right now not expecting enough accumulation to be a widespread
hazard. With strong cold air advection the high temperature in
the douglas and hazlehurst areas will be near sunrise with steady
or dropping temperatures during the day but then as skies clear
late in the afternoon and evening the bottom drops out of the
thermometer! Wind chill temperatures by late in the day will be
in the lower 30s to upper 20s in a few areas.

Elsewhere looking at a day characterized by some mid to low level
cloudiness and dropping temperatures through the day as the cold
air advection takes over. Wind chill temperatures will only be in
the upper 30s to lower 40s tomorrow with highs struggling to stay
in the upper 40s to lower 50s.

Wednesday night through Friday night ...

a significant cool down is expected as 5h trough moves across the
region during the evening hours and as surface high pressure builds
into the central gulf coast overnight. An arctic air mass
with much colder and drier conditions will be ushered in as
the high builds closer the cold air mass will settle in for
Wednesday night into Thursday with mainly clear skies. Lows Wednesday
night will be in the lower to middle 20s leading to a hard freeze
over the majority of the region, except for between the st johns
and the sea, where readings will be closer to freezing. Wednesday
night will likely be the coldest night of the season thus far.

The high will build overhead Thursday afternoon through Friday,
then start moving to the east Friday night. Temperatures will
struggle once again Thursday with highs mainly in the upper 40s to lower
lower 50s. Another freeze to hard freeze is expected Thursday night.

As cold advection subsides Friday temperatures will start to make a
recovery, but still below seasonal averages. Highs Friday will be
generally in the 50s, and lows Friday night will be just below the
freezing mark interior SE ga and suwannee valley to near 40 north central
florida and the upper 30s first coast beaches.

Long term Saturday through Tuesday ...

warm air advection will occur this weekend as high pressure
remains east of the region with a easterly wind developing over fl
which on the southwest side of the high and southerly wind over
ga which will be on the northwest side of the surface ridge. This
onshore flow pattern will allow highs to rebound in the 60s on
Saturday. Lows Saturday night will be in the 40s, near 50 first
coast beaches with some lower 50s north central fl.

High pressure will remain to the east of the region Sunday and Sunday night.

Moisture subtlety increases Sunday, low clouds will increase on
Sunday with precipitable water values increasing around .75". Most
of the moisture will be confined at or below 925mb through Sunday
night with dry conditions above this level with a passing shower
or two possible with pops in the 10 to 15 percent range. Surface
dew points are forecast to be be in 57 to 61 degree range
overriding near shore sea surface temperatures of 51 to 54
degrees.

Rain chances will increase from Monday afternoon into early Tuesday, as
moisture builds ahead of a long wave upper trough and as cold front moves
eastward across our area. Slightly cooler and drier air will return behind
the front from Monday night into Tuesday.

Aviation
Vfr conditions expected during the afternoon and early evening
with some cloudiness moving toward sunrise tomorrow. Winds will
be northeast today and gradually shifting to the northwest as a
dry cold front moves through all the stations overnight. Could
see a brief period of shallow ground fog, especially at cecil
airport and gainesville overnight.

Marine
A dry cold front will pass across the coastal waters overnight
with and increase in winds. Expect to maintain small craft
exercise caution criteria for seas overnight with small craft
advisory conditions likely for Wednesday afternoon and night.

On Wednesday night we could see occasional gusts up to gale
force over the 20 to 60 mile offshore segments.

Rip currents: low risk of rips currents on Wednesday due to an
offshore flow.

Fire weather
A dry cold front will move across the area overnight with
increasing winds and drying conditions on Wednesday. Afternoon
relative humidity values will be in the 40 to 50 percent range
with a northwest flow at 8 to 12 mph. Maximum dispersion tomorrow
will be in the 65 to 80 range over southeast georgia and 35 to 60
over florida with the lowest values over the ocala national
forest.
