Synopsis
Cool, dry high pressure will dominate the pattern through the
weekend. Another cold front may move through the region by mid
week, followed by stronger high pressure and continued cool
conditions for the remainder of the work week.

Near term until 6 am this morning
Pre-dawn: stratocumulus fields stuck around longer than anticipated
overnight, recently dissipating from west to east and widespread
clearing now ongoing along the immediate coastal zones. Skies should
be mainly clear at dawn with just few clouds lingering near the
coast. Cold air advection finally getting some clear skies to
work with well inland, temps reaching the mid 30s and we have
continued our freeze warning from metter over to statesboro and
north to millen, sylvania and allendale. Winds should begin to
subside along coastal areas over the next few hours.

Today: cyclonic flow aloft will abate as a strong upper jet shifts
off to the northeast and the upper flow flattens. Surface high
pressure will build over the region while deep layered dry air
should result in sunshine today. There will be a few high clouds
across the area but models keep these thin and scattered for
the most part. We made very little change to forecast highs
today which mainly be in the upper 50s across the region. Weak
downslope may result in a few highs around 60-61 degrees in spots
along the coastal corridor.

Tonight: the main concern under clear skies will be the setup
for strong radiational cooling and temps falling into the mid
30s many areas along and west of u.S. 17. We expect to hoist
frost advisories for many inland zones while we inspect the
outcome of this morning's potential inland freeze for possible
additional freeze warnings. We think coldest rural areas have a
decent chance of seeing a light freeze north of i-16 in ga and
along northwest zones of southeast sc.

Short term 6 am this morning through Sunday
West-southwest upper level flow and weak surface high pressure will
prevail over the region through the period with no significant
precipitation expected.

Saturday: temperatures will be the coolest for this period. After a
very cold start, temperatures are expected to climb into the mid 60s
by afternoon. Winds will be light as high pressure becomes centered
over the mid atlantic states. By Saturday night, the surface ridge
will elongate and shift more into the atlantic. However, low level
light north-northeast winds will remain over the region, which
should allow temperatures to drop to around 40 well inland, to the
mid 40s to around 50 closer to the coast.

Sunday and Monday: temperatures moderate as the center of the
surface high moves farther offshore into the atlantic. This allows a
weak coastal trough to develop. Models indicate some moisture return
and therefore slight chance low end chance for light showers, mainly
near the coast, later Sunday through early Monday. The coastal
trough weakens moves offshore Monday as weak surface high pressure
tries to build back from the west. High temperatures generally in
the upper 60s to around 70, and lows Sunday night in the lower 40s
well inland to the lower 50s closer to the coast.

Long term Sunday night through Thursday
A broad upper trough moves across the oh river valley Tuesday and
then across new england southeast canada Wednesday. At the surface,
stronger cooler high pressure builds from the northwest behind a
cold front, which moves through with little no precip. Later
Tuesday. The surface ridge remains north of the region Wednesday and
Thursday, then shifts east offshore of the mid atlantic by Friday.

The global models show a return of deep layer moisture from south to
north by Friday as the low level flow veers to southeast. Given the
uncertainty out that far, have kept low end chance pops, which also
seems to collaborate well with surrounding office. High temperatures
starting off in the mid to upper 60s Tuesday, then cooler for
Wednesday and Thursday behind the cold front, with highs generally
in the lower 60s. By Friday, temperatures moderate into the upper
60s. Low temperatures will be cool, ranging from the low 40s well
inland to around 50 closer to the coast.

Aviation 09z Friday through Tuesday
Skies were clearing along the coastal corridor pre-dawn.VFR
conditions will prevail through 06z Saturday.

Brief flight restrictions will be possible later Sunday through
early Monday as a weak coastal trough tries to develop with a low
end chance for showers. Otherwise,VFR is expected to prevail for
both sites through mid week next week.

Marine
Early this morning: cold advection maintaining elevated winds
throughout, with NW winds as high as 20 kt all waters. However,
better mixing of the 30 knots of geostrophic winds at 1000 mb
will lead to frequent gusts of 25 kt on the outer ga waters.

Thus we have small craft advisory flags only for these waters
beyond 20 nm. The other atlantic waters will experience
occasional gusts near 25 kt, but not enough to warrant the
advisory. Seas will be as large as 3-5 ft within 20 nm and 5-7
ft further out.

Winds and seas will decrease today as high pressure builds in
from the west. From this afternoon through tonight, wind speeds
will be much lighter as the mean flow veers from NW to N and ne
by early Saturday. Seas will subside to less than 3 ft near
shore and 3-4 ft out near the gulf stream.

No highlights are expected through the period. Weak high pressure is
expected to remain just north of the waters through Sunday. As the
high shifts eastward later Sunday, a weak coastal trough tries to
develop, which may bring a chance for showers Sunday night and early
Monday. Another cold front likely pushes through the waters later
Tuesday. Winds generally 15 knots or less and seas 2 to 4 feet
through Tuesday. Winds increasing to around 15 knots behind the
front later Tuesday through Wednesday. Some gusts near 20 knots will
be possible Tuesday night and Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
