Synopsis
A warm front will move north through the area today. A cold
front will then move through late tonight into Thursday morning
followed by high pressure through early next week. Another cold
front will move through next Tuesday.

Near term through tonight
Today: no significant changes were made with the latest forecast
update. A low-level warm front will shift north through the area
bringing an end to the inland high pressure wedging. A few
showers are expected across the area today, generally shifting
from ga into sc with the band of greater low-level moisture.

Although we should see a bit of Sun especially in ga we think it
will be more cloudy than not overall. However, despite the
clouds, temperatures will increase to above normal levels given
the strengthening low-level warm advection. Highs should range
from the in the mid upper 60s for most of sc and along the ga
coast with lower 70s across inland portions of ga. Southeast
winds will shift more southerly and increase to 15 to 20 mph
with gusts near 25 mph during the afternoon.

Tonight: mainly dry conditions should prevail for much of the
early evening hours. Winds will continue to increase with
turbulent low level mixing resulting in steady to slowly
rising temps across the region. Tonight's low temps could
certainly occur at many locations not long after sunset before
the stronger winds kick in. A progressive and vigorous upper
wave will sweep into the lower gulf coast region and reach north
ga by dawn on Thursday. Significant upper dynamics and pwats
exceeding 1.5 inches will accompany a strong cold front into the
region late tonight. Mostly shallow convective rains and
perhaps a narrow strongly-forced line of heavier rains will
move into the forecast area after midnight, nearing the coast
toward daybreak. We will begin to see breezy to windy conditions
develop as a 55-65 kt low level jet sweeps atop the region. It
would not be surprising to see wind speeds nearing wind advisory
levels along some of the coastal zones for a period later
tonight. Mid level instability is quite weak and very little
cape progged at the boundary layer suggest any thunder or deeper
convection will be quite limited. Rains are expected to be at
least briefly heavy at times late tonight with amounts ranging
from 1 2 inch to over an inch in some areas.

Short term Thursday through Saturday
The cold front will be pushing off the coast Thursday morning,
taking with it the widespread rain showers. Cold advection will
quickly begin following the front, causing temps to fall through
the morning hours. Increasing sunshine and downslope flow
developing by early afternoon should offset the cold advection
and cause temps to level off. The daytime high temperature may
well occur around sunrise at many sites. Although low-level wind
speeds will decrease quickly during the day, cold advection will
support deeper mixing, thus breezy conditions expected.

Cool and dry high pressure will build over the area Friday
through Saturday, resulting in clear skies, highs in the low mid
50s and lows in the upper 20s to lower 30s.

Long term Saturday night through Tuesday
Dry weather and moderating temperatures expected Saturday night
through Tuesday as high pressure gradually shifts east. A mostly
dry cold front will sweep through Tuesday night, followed by a
considerable cool down.

Aviation 15z Wednesday through Sunday
Vfr for much of the period through midnight, although MVFR cigs
are possible at times during the day. Winds will veer to a
southerly component later today and become quite gusty by late
today and this evening as a strong low level jet builds into the
coastal corridor. Isolated to scattered light showers possible
with a warm front and building moist low level wind field today.

After midnight: convective rains are expected to spread into
the coastal corridor, timing is mainly after 08z 24. Strong
surface winds are expected with speeds perhaps 20g30kt at
times in the warm sector ahead of the rains. Ifr CIGS and
vsbys are possible late in the period.

Extended aviation outlook: MVFR ifr ceilings vsbys will clear
out by late Thursday morning, though breezy conditions will
occur through Thursday afternoon.

Marine
Today: a coastal trough will shift through the area as a warm
front with southeast to east winds shifting to more southerly.

Small craft advisories will remain in effect for elevated
winds gusting near 25 kt and at least 6 ft seas across the
charleston nearshore waters and offshore ga waters.

Tonight: winds will increase as strong low-level wind fields
spread over the waters due to an approaching cold front. There
is some concern for gales to develop, mainly out closer to the
gulf stream waters, and we have raised a gale watch for all
waters outside charleston harbor. Seas will build substantially
as well, especially beyond the pilot buoys, and thus hazardous
to dangerous conditions are expected across all waters.

Thursday through Sunday: the southerly low-level jet will be at
its peak around 12z Thursday before the cold front moves
through. Winds will shift to offshore during the day as the cold
front moves farther offshore. Though low-level winds will
decrease considerably as the day wears on, deeper mixing in cold
air advection will allow gusty winds to persist.

Small craft advisory conditions will continue for all waters
through at least Thursday afternoon, though most waters will
continue to see 6+ ft seas through parts of Thursday night or
into Friday morning.

High pressure will build over the waters late Friday through
early next week, yielding relatively quiet marine weather.

Tides coastal flooding
A coastal flood advisory for minor salt water flooding remains
in effect for the entire coast through 11 am.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
