Synopsis
Cool, dry high pressure will return through much of the
weekend. High pressure will generally persist over the
southeast states next week.

Near term until 6 am Friday morning
Drier air is slowly working its way in from the west but it will
likely be early evening before the overcast skies begin to erode
from west to east. Most areas should be clear by shortly after
midnight. Strong cold air advection will occur overnight,
strengthening after midnight as winds veer to nw. 12z models
were considerably colder with overnight lows. We nudged temps
down 1-2 degrees which now results in about two hours of 32
degree temperatures over far inland ga sc zones. In
collaboration with WFO cae and ffc we issued a freeze warning
for a handful of inland zones.

Short term 6 am Friday morning through Sunday
Surface high pressure will build into the area Friday and Saturday
and then shift northeast of the area by Sunday.

Friday: sinking motion in the wake of the strong system well to the
northeast of the area and downslope low level wind flow off the
southern appalachians will result in clear skies. A cold start, some
weak cold advection, and limited mixing due weak winds and a low sun
angle will result in highs being in the mid to upper 50s. An ideal
radiation cooling night is expected Friday night with light winds.

Generally went a bit cooler than mav and met guidance and closer to
the 00z ECMWF ensemble MOS means which indicate a decent threat for
frost except for areas near the coast and away from lake moultrie.

For now, expanded the patchy and scattered frost areas a bit further
south and east with this update, but not as far as might be needed.

Not explicitly forecast, but there could be a few areas in the west
that touch freezing late Friday night and early Saturday morning.

Frost advisories will be likely and freeze watches warnings will be
possible. Lows are forecast to range from the mid 30s far inland to
the lower and mid 40s near the coast.

Saturday and Sunday: despite a cool start, some warm advection,
abundant sunshine and better mixing will result in high
temperatures on Saturday rising to the mid 60s in most areas.

Clouds will begin to increase Saturday night as isentropic lift
along with increasing low level moisture commences. There could
be some light rain that moves inland from the ocean on Sunday
and included mention of a slight chance for rain generally
within 20 miles of the coast. Further inland, feel that rain
chances are too low to mention in the forecast. Despite more
cloud cover, warm advection and a warmer start to the day will
help high temperatures rise to the mid 60s in the northwest,
north, and along the coast in south carolina to the lower 70s
in the south away from the coast.

Long term Sunday night through Thursday
Dry weather will prevail through early next week as cooler high
pressure moves into the area. A weak area of low pressure may
develop offshore and cause a few showers mainly near the coast.

Temperatures should mostly stay near normal.

Aviation 20z Thursday through Tuesday
Lot of moisture continues to wrap around the low pressure system
moving up the nc coast, keeping MVFR or lower ceilings in place.

Gradual improvement expected through the remainder of the
afternoon withVFR by early this evening.

Extended aviation outlook: other than a very low threat for subVFR
conditions Sunday night and into Monday,VFR conditions should
prevail through Tuesday.

Marine
Cold advection will occur tonight, maintaining winds 15-20 kt
with some higher gusts. We held onto the small craft advisory
for charleston nearshore waters until 4 am due mainly to
lingering 6 ft seas though also better chances for some 25 kt
wind gusts. SCA for offshore ga waters continues into fri
morning.

Winds and seas will decrease Friday as high pressure builds in
and then generally light winds at or below 10 knots are expected
through Sunday. A weak reinforcing cold front will move through
the waters Sunday night and this will result in an uptick of
the winds generally into the 10 to 15 knot range later Sunday
night through Tuesday night with seas mainly from 2 to 4 feet
during this period.
