- Colder Weather Returns This Week. Freeze Warning Tonight for
Southeast Georgia & I-10 Area. Freeze Watch Tuesday Night for
Southeast Georgia & Inland Northeast Florida with. Additional Inland
Light Freezes with Widespread Frost Potential Wed Night

- Small Craft Advisory Through Tuesday Afternoon for Coastal Waters

&&

.NEAR TERM /THROUGH TONIGHT/...
Early this morning...Advective light freeze still on track across
inland SE GA where temps will bottom out around 30F just after
sunrise this morning, with 30s expected elsewhere, along with wind
chills in the middle to upper 20s, likely remaining just above Cold
Weather Advisory criteria.

Today...Below normal temps are expected as cold air advection in NW
flow will continue with occasional high clouds at times, mainly
across NE FL. This will will hold Max Temps in the upper 40s to
around 50F across SE GA and only reaching the lower to middle 50s
across NE FL.

Tonight...Cold high pressure builds west of the region with cold air
continuing to sink into the local area on NW winds at 5-10 mph. This
will set the stage for a moderate Freeze inland with widespread lows
in the upper 20s, along with pockets of Hard Freeze temps with lows
into the middle 20s in normally colder locations, although slightly
elevated winds around 5 mph will keep temps from totally bottoming
out. Areas/Widespread frost is expected as well over inland areas bu
sunrise Wednesday morning. The NW flow will push the cold air mass
all the way to the Atlantic beaches with a light freeze expected
along the I-95 corridor with lows in the lower 30s all the way to
beachfront locations in SE GA, and closer to the ICWW of NE FL
coastal locations. For now will keep the Freeze Watch placement as
is, but may need to be pushed eastward to the I-95 corridor if
colder model trends continue. The slightly elevated NW winds at 5-10
mph will produce wind chills in the lower to middle 20s late tonight
through early Wednesday morning and a Cold Weather Advisory headline
may be required for NE FL late tonight, but still too marginal for
issuance with this package.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
High pressure builds to the west of the area over the Gulf midweek,
shifting towards the FL peninsula by Thursday evening.

Wednesday, high pressure over the Gulf will continue to bring
northwesterly-westerly winds over the local area. Cold and dry air
continues to advect into the area, but clearer skies for most of the
day will allow for temperatures be a couple of degrees warmer than
Tuesday. Daytime highs will be in the 50s area-wide, with warmer
temperatures towards north central FL and along the coast. The dry
conditions will bring min RHs to dip into lower 20s across SE GA,
and the mid to upper 20s across NE FL. By Wednesday night, Lows will
be in the 30s area-wide setting up the potential for a light freeze
primarily across inland locations as coastal locations will be near
40. With light winds and near/at freezing temperatures, patchy to
areas of frost is likely to develop for inland locations west of the
I-10 corridor.

Thursday, a warming trend begins as daytime highs will be in the 60s
area-wide. Clear skies will persist for much of the day as westerly
winds develop as the high pressure over the Gulf builds towards the
FL peninsula. Dry conditions will begin to steadily improve as min
RHs rise into the 30s. Overnight Lows on Thursday night will
primarily be in the upper 30s to lower 40s.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
The high pressure over the FL peninsula shifts away from the area as
a Low pressure system moves into the SE CONUS on Friday. The Low
pressure system associated cold front will push near the area on
Friday evening, bringing chances of precipitation for locations
across far interior SE GA. By Saturday the front will begin to cross
into the area, with showers and isolated thunderstorms spreading
south through the day. Most activity currently is expected for
locations along and north of the I-10 corridor with widespread to
numerous showers and isolated chances for thunderstorms during the
afternoon hours on Saturday, while isolated chances of showers
expected for locations south of the I-10 corridor through Saturday
night. By Sunday, precipitation chances begin to dwindle as the Low
pressure and its associated cold front will be clear of the area.

Temperatures will continue to warm through Saturday ahead of the
cold front, reaching above seasonal norms by Saturday. Behind the
front, temperatures are not expected to cool to much on Sunday.

&&

.AVIATION /06Z TUESDAY THROUGH 06Z WEDNESDAY/...
VFR conds are expected through the period with NW to N winds around
10 knots with occasional gusts to 15-20 knots at times. Lighter NW
winds will set up tonight after sunset.

&&

.MARINE...


A cold front will move southeast of area waters early this morning,
with strong high pressure building behind it. Conditions will be
elevated Today, 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 northern Gulf. An area
of low pressure will move just north of the waters this weekend.

Rip Currents: SE GA Moderate Tuesday
              NE FL Moderate Tuesday

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

drier into the region. The dry air will bring Min RH values into the
20s area-wide Today and Wednesday. The driest air will be found over
inland southeast Georgia with RH values in the lower 20s, while
northeast Florida will have RH values in the mid to upper 20s. Winds
won`t be as elevated as Monday, but will still bring a light breeze
Today, remaining below Elevated Fire Danger Criteria. Fair to Good
