Synopsis
High pressure will build over the region through early Monday.

Low pressure is expected to move across the region Monday night
and Tuesday. High pressure will then rebuild.

Near term through tonight
As of 1045 am: the current forecast remains on track. I will
update the forecast parameters to align observations.

Previous discussion:
today: the mid upper level trough across the northeastern us
will move off the coast and shortwave ridging will steadily move
across the mississippi valley. At the surface, high pressure
will be the primary feature in the wake of a cold front drifting
to the south. Deep dry air will remain in place and a dry
forecast with clear skies is in place. Highs are forecast to be
very similar to Friday with temperatures ranging from the upper
60s across the tri-county region to the low 70s closer to the
altamaha.

Tonight: the tranquil pattern will persist as high pressure
remains across the forecast area. A few high clouds could pass
through at times, but no impact on the forecast. With a weak
pressure pattern in place for much of the forecast area, good
radiational cooling conditions will set up. Look for lows to
range from around 40 inland to the low 50s at the coast.

Short term Sunday through Tuesday
Warm advection will occur Sunday through Monday as the surface
high shifts offshore and deep southerly flow strengthens. Upper
shortwave energy will move into the carolinas on Monday with a
surface low shifting from the sc midlands into the grand strand
Monday evening. The best moisture and forcing will be over far
northern areas closer to the surface low track. We maintained
scattered showers, along with isolated thunderstorms Monday
afternoon evening. Isentropic ascent may produce a few lingering
showers into Tuesday as a backdoor front drops through the
area. Considerably cooler air will usher in behind the front on
Tuesday. Highs in the mid upper 70s Sunday-Monday will drop to
the 60s Tuesday.

Long term Tuesday night through Friday
Somewhat cooler weather will continue Tuesday night through
Wednesday night before temperatures moderate with the surface
high moving offshore. Temps expected to be pushing the upper 70s
to around 80 late next week with mainly dry conditions.

Aviation 15z Saturday through Wednesday
Vfr conditions will prevail at kchs and ksav through 12z
Sunday.

Extended aviation outlook: flight restrictions possible Monday
night through Tuesday night.

Marine
Today through tonight: northeast winds will prevail this
morning behind a southward moving cold front. Wind speeds are
expected to top out in the 15-20 knot range. Then by the
afternoon the gradient will relax significantly and winds will
veer to become onshore. Speeds are forecast to be 10 knots or
less. Overnight, winds are expected to remain onshore and top
out around 10 knots. Seas will peak this morning, highest 3-5
feet in the charleston county waters. Then overnight seas will
drop off and become 1-3 feet everywhere.

Gusty southwest winds expected Monday ahead of the surface low
but conditions are currently forecast just below advisory
thresholds. However, a persistent strong northeast gradient will
likely yield advisory conditions for most if not all of the
waters Tuesday through at least Thursday.

Fire weather
Relative humidity values are expected to drop into the 20 to 25
percent range this afternoon. However, winds will be much
lighter today so no fire danger statements are planned at this
time.

Equipment
The kclx radar is inoperative. Parts are on order and repairs
are expected to occur on Monday.

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.
