Synopsis
Low pressure will move northeast of the area today with cool
and dry high pressure returning through much of the weekend.

High pressure will generally persist over the southeast states
next week.

Near term through tonight
A deep cutoff low over the central mississippi valley will lift
northeast toward the great lakes this afternoon. Meanwhile a
surface low continues to move up the nc coast away from the area
while a trailing cold front pushes through the local area.

Plenty of lingering low-level moisture will maintain overcast
skies much of the day, though drier air will finally begin to
scour out the clouds across interior southeast ga during the
afternoon. Weak cold air advection and extensive cloudiness will
keep temps from rising much above the low mid 50s.

Tonight: skies will eventually clear with cold air advection in
the lower levels on tap as high pressure builds east toward the
area. Late night readings across the area will fall into the
mid to upper 30s along with light west to northwest breezes.

We were compelled to introduce patchy frost over much of the
region to the west of u.S. Given the anticipated sunrise temps
and a chance that inland sheltered locations decouple late.

Short term Friday through Sunday
Confidence is high this period. Expect improving conditions Thursday
as low pressure moves farther away up the coast. Rain should
generally end from south to north Thursday morning although a few
showers could linger across the sc lowcountry into late Thursday
afternoon. Instability looks minimal over land but can't rule out a
few thunderstorms mainly near the charleston county coast early in
the morning. Otherwise high pressure will build in and prevail
through the end of the week. The main concern late week will be the
potential for some frost Friday and Saturday morning across inland
areas where temperatures could reach the mid 30s. The best chance
for at least scattered frost will likely be Saturday morning though
when winds are lighter.

Long term Sunday night through Wednesday
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 15z Thursday through Monday
The low pressure area offshore was moving up the carolina coast
this morning and rains on the backside of the system have become
more scattered and light, some drizzle is even possible through
the morning. The primary concern today with be timing the slowly
improving conditions as CIGS initialized ifr through the
coastal corridor at daybreak. Forecast soundings suggest cigs
should lift to MVFR at ksav either late morning very early in
the afternoon at the latest, then clouds scatter out late in the
day as drier air in the low levels filters in. At kchs, ifr cigs
may last a while longer into the afternoon. Low level west flow
and the arrival of drier air by 21z today should signal cigs
in the MVFR range briefly before scattering out not long after
dusk.

An additional concern is llws at kchs and perhaps more limited
risks at ksav through mid morning.

Extended aviation outlook: flight restrictions, likely below ifr at
times, expected much of Thursday, especially at kchs. Otherwise no
significant impacts expected through the weekend.

Marine
Today: gradually improving conditions as the surface low
continues moving farther up the coast. Lingering seas will
prevent us from dropping the scas for the sc nearshore until
later this afternoon or early evening, and offshore ga by fri
am.

Tonight: cold air advection over the waters while high pressure
builds in from the west. We expect decent surges that will keep
conditions in SCA mode over outer ga waters. It is more marginal
near-shore but scas are possible in these legs. Seas will be
higher offshore in the northwest flow regime.

Thursday through Sunday: quite poor marine conditions expected into
early Friday as a storm system moves north of the area. Small craft
advisories will likely come down Thursday afternoon for the
nearshore waters but linger through Friday morning for the offshore
ga waters. Otherwise no significant concerns through the end
weekend.

Chs watches warnings advisories
Ga... None.

Sc... None.

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.
