Area Forecast Discussion
National Weather Service Charleston SC
849 PM EDT Tue Aug 4 2020

.SYNOPSIS...
A stationary front will linger near the area through Thursday.
Atlantic high pressure will rebuild late week through the
weekend.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Only minor changes were made for the mid-evening update mainly
to lower pops to slight chance. Lows will range from the mid 70s
inland to the the lower 80s at the beaches and Downtown
Charleston.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
The area will remain on the eastern periphery of a long wave
trough during the period while a series of weak embedded
shortwaves moves from southwest to northeast through the
forecast area. At the surface, a weak trough/boundary will
linger just inland. With highs in the low to mid 90s each day
and surface dewpoints in the 70s, ample instability will be
present for scattered to numerous showers and tstms to develop
each afternoon/evening.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Not much change to the weather pattern expected into early next week
with the continuation of near to above normal rain chances and
temperatures.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
VFR. Showers/tstms west of KSAV could make a run for the
terminal by 00z. Any mention will be decided based on radar
trends at the 2330z transmission window. The risk for tstms
tomorrow afternoon looks to west up west of both KSAV and KCHS,
thus no mention will be included at this time.

Extended Aviation Outlook: VFR conditions will prevail outside
of isolated afternoon/evening convection.

&&

.MARINE...
This Evening and Tonight: A weak pressure gradient will prevail
between high pressure across the western Atlantic and a trough of
low pressure well inland. In general, conditions will remain well
below Small Craft Advisory level conditions with south winds between
10-15 kts. Seas will range between 2-4 ft.

Wednesday through Sunday: Atlantic high pressure will maintain
typical summertime conditions over the marine area with mostly
southerly winds 10-15 kt and seas 4 feet or less.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
