.SYNOPSIS...
Strong Atlantic high pressure will prevail into this weekend,
then a cold front will move through Monday. High pressure will
then rebuild.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Overnight: Here it is early April during the overnight hours,
and many temperatures and dew points are still above 70F. This
is the result of a southerly synoptic flow and partly to mostly
cloudy skies. Since winds never fully decouple, we`ll be lucky
to get lows down into the upper 60s, or about 15F above climo.
Low stratus will be widespread with considerable moisture
trapped beneath a 2-3C inversion. Given that 925 mb winds are
20-30 kt, these clouds will not build down low enough to create
more than some patchy fog concerns. The most likely occurrences
of such will be where rainfall occurred Wednesday.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/...
Deep layered ridging over the Eastern United States and western
Atlantic will maintain dry weather and above normal
temperatures. A prevailing southerly flow will help enhance the
afternoon sea breeze each day, so locations closer to the coast
will remain considerably cooler than places farther inland.
Highs inland will reach the mid to upper 80s each day, with a
few readings in the lower 90s possible closer to the Central
Savannah River Area (CSRA).

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Ridging will continue through Sunday, then a longwave trough
will sweep east Monday, pushing a strong cold front through the
area. Fairly widespread showers and thunderstorms expected
Monday, then temps cool down considerably for Tuesday and
Wednesday.

&&

.AVIATION /04Z THURSDAY THROUGH MONDAY/...
The 00z TAF period begins with mostly VFR conditions across the
area, though there are some patches of MVFR ceilings around. VFR
is mostly expected for the next several hours before the
potential for stratus develop increases from around midnight
after. Prevailing MVFR ceilings are expected at KCHS, KJZI, and
KSAV and have been timed into the TAF`s around 04-06z. IFR
ceilings can`t be ruled out at any of the 3 TAF sites, but the
best chances appear to be at KSAV which is where they are
included beginning at 07z. A return to VFR isn`t expected until
as early as midday or by the early afternoon. South winds will
be breezy Thursday, beginning in the late morning. Frequent
gusts up around 20 knots can be expected.

Extended Aviation Outlook: Nighttime ceiling restrictions
possible Thursday night.

&&

.MARINE...
Overnight: High pressure across Bermuda will continue to
dominate with increasing south to southeasterly flow across the
coastal waters. Winds of 10 to 15 knots will be common with some
higher gusts, while seas build into the 3 to 5 foot range.

Fairly quiet marine conditions expected Thursday through
Saturday. Southerly flow will strengthen Saturday into Sunday as
an upper trough approaches from the west. 6 ft seas could
encroach on the outer portions of the offshore GA and nearshore
SC waters. Sunday and Sunday night we could see 25 kt wind gusts
in the Charleston nearshore waters and Charleston Harbor, so
Small Craft Advisories cannot be ruled out.
