.SYNOPSIS...
Atlantic high pressure will prevail through much of the week while
a weak trough persists inland.

&&

.NEAR TERM /THROUGH TONIGHT/...
Isolated convection will quickly wane this evening with the loss
of insolation. Expect a dry and humid night for the region with
overnight lows ranging from the mid 70s inland to the lower 80s at
the beaches, Downtown Charleston and around Lake Moultrie. Some
isolated, nocturnal convection should redevelop near the western
wall of the Gulf Stream after midnight, but this activity will
largely remain offshore as low-level winds veer back to the
southwest.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
Once again, little to no change in the pattern through mid week.  A
deep layer ridge will continue over the region. Deep layer moisture
will be the lowest/most marginal for Monday, which will translate to
the lowest pops/coverage for afternoon convection. Have maintained
15-20% pops. By Tuesday and Wednesday, deep layer moisture increases
slightly, but still keeping afternoon pops in the slight chance to
very low end chance levels. Convection will be triggered by the sea
breeze, then could be locally enhanced by any boundary interactions.
Thus, an isolated strong storm cannot be ruled out. Steering flow
will continue very light, which increases the chance for locally
heavy rainfall. Temperatures will continue above normal with highs
in the lower to mid 90s and lows in the mid to upper 70s most
areas.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
The synoptic pattern will change very little in the long term
period. Mid/upper level ridging will persist through late week. At
the surface, the primary features will be Atlantic high pressure and
a trough of low pressure inland. A weak front may approach late
week, however it will likely stall and eventually dissipate before
reaching the local area. Fairly typical summertime PoP scheme in the
forecast, generally 20-30% chances. Coverage will peak in the
afternoon and evening when instability is greatest. Another period
of above normal temperatures with highs forecast in the mid/upper
90s and lows in the mid/upper 70s.

&&

.AVIATION /17Z SUNDAY THROUGH THURSDAY/...
VFR. Showers/tstms could get close to KCHS 18-22z per recent radar
trends, so will carry a VCSH or VCTS for now as most of this
activity will remain to the North and Northwest of the terminal.

Extended Aviation Outlook: VFR will prevail both sites through
the work week. Brief flight restrictions possible each afternoon
with isolated showers/thunderstorms.

&&

.MARINE...
Tonight: South winds will gradually veer southwest later this
evening. Winds will largely remain less than 15 kt with seas 2-4
ft. Isolated showers/tstms should redevelop closer to the western
wall of the Gulf Stream later tonight.

Monday through Friday: No highlights expected through the period.
Atlantic high pressure will prevail through the period with south-
southwest winds through Thursday. Still expect winds to be 15
knots or less and seas generally 3 to 4 feet or less. Isolated to
scattered mainly late night through morning showers and
thunderstorms.
