.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 THURSDAY MORNING/...

Afternoon composite analysis reveals a nearly stalled boundary
arcing through E/SE Georgia into the Atlantic and weakening
inverted surface trough extending up through the outer coastal
waters. SPC mesoanalysis shows 1500-2500 J/Kg MLCAPE across the
region, highest across inland SE Georgia. Isolated showers have
popped across the local forecast area this afternoon,
particularly across southeast South Carolina. Further south,
some semblance of a sea breeze boundary is pressing inland
through far southeast Georgia (JAX CWA) where there is a small
cluster of showers/storms moving northward.

Rest of this afternoon: Isolated to scattered showers and some
thunderstorms remain possible heading into the evening,
especially across the Charleston tri-county area as well as
inland southeast Georgia well west of the I-95 corridor. Highest
pops were maintained for those areas. Severe weather potential
still appears on the lower side. But given decent DCAPE values
across southeast Georgia (in excess of 1000 J/Kg) and at least
some modest stronger winds aloft, gusty wind potential cannot be
ruled out.

Tonight: With the loss of diurnal heating and the lack of
forcing, showers and t-storms will quickly fade during the
early and middle evening hours, and the rest of the night will
be rainfree. The mid level ridge slowly starts expanding west
and northwest, and heights locally begin a slow climb, while a
large region of Atlantic high pressure encompasses the local
counties. While there could be a little fog where earlier rain
occurs, given 15-20 kt of 1000 mb geostrophic winds, fog
potential appears much lower tonight compared to last night.
Low temperatures in the middle to upper 60s anticipated, a good
15 degrees above climo values.

&&

.SHORT TERM /6 AM THURSDAY 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 /19Z WEDNESDAY THROUGH MONDAY/...
KCHS/KJZI/KSAV: MVFR cigs linger across the region, although
cigs should further lift into the low VFR range in the next hour
or two. A few showers are also popping across the area and
could impact the terminals through the afternoon...particularly
across the KCHS and KJZI terminal sites...along with a low end
chance for TSRA. Also, gustier south-southeasterly winds
continue through the afternoon with gusts running 17 to 22
knots.

Shower activity and gustiness ends this evening. Another period
of low (MVFR-IFR) ceilings is possible again late this evening
and overnight followed by slowly improving conditions Thursday
morning.

Extended Aviation Outlook: Nighttime ceiling restrictions
possible Thursday night.

&&

.MARINE...
Tonight: 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.

Rip Currents: A modest onshore wind, and swells around 3 feet
every 10 seconds, will result in a Moderate Risk of Rip
Currents at all beaches into early evening.

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.
