Area Forecast Discussion
National Weather Service Charleston SC
348 PM EDT Wed Jul 19 2023

.SYNOPSIS...
A weak front will stall over the area late week into the
weekend, then high pressure will rebuild early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Fixed low-amplitude ridging lingers across the southwest CONUS
with downstream troughing across the Atlantic coast. Periodic
rounds of convection continue along the northeast periphery of
the ridge with the latest decaying round of showers/thunder
moving into northern Georgia and the western Carolinas. Here at
home, sea breeze is largely pinned at the coast and CINH
continues to keep convection at bay with only minimal shallow Cu
development in our area thus far. There are some small showers
northwest of the CWA that have developed recently but still a
county or two away.

Tonight: Other than the showers to our northwest sneaking into
the far western part of the CWA, I don't expect much in the way
convection through the rest of the afternoon. Meanwhile, convectively
induced impulse from the upstream decaying convection will be
pressing into the region this evening. This should be enough to
kick off showers and thunderstorms this evening and potentially
lingering into the overnight hours, although the exact
timing/location remains nebulous.

Otherwise, temperatures will dip back into the middle and upper
70s for most, around 80 at the coast.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
A broad upper ridge will remain west of the area on Thursday.
Weak shortwave energy is forecast to drop through the northern
zones late Thursday afternoon into the evening which could spur
clusters of thunderstorms. Bulk shear values may increase to
30-35 kt late in the day and CAPE values will be above 2,000
J/kg in this area. There will therefore be a risk for severe
thunderstorms, mainly in the Charleston Tri-County area.
Damaging winds look to be the main threat. High temps in the mid
to upper 90s and mid-70s dewpoints will result in heat indices
of 106-112F, so a Heat Advisory may be needed for a portion of
the area.

A deep layered ridge will exist on Friday, with hot temperatures
persisting. Highs in portions of southeast GA could exceed 100F,
while upper 90s will prevail elsewhere. Strong mid-level
subsidence should limit convective development during the day
and the sea breeze will likely struggle to move inland. Late in
the afternoon through the evening, a weak shortwave could
ripple through, bringing a better chance for convective
development. The main issue will be heat indices potentially
exceeding 110F. A Heat Advisory will probably be needed for at
least the coastal counties.

Upper height falls expected on Saturday as a broad upper trough
shifts into the eastern United States. Decreasing thicknesses
should bring a slight break from the heat, though highs will
still reach the low to mid 90s. Upper levels will be much more
favorable for afternoon convection, so we have 50-65% PoPs
Saturday afternoon.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A weak surface front stalled over the area Sunday will support
better coverage of showers and thunderstorms during the day. A
more typical summer pattern will then exist Monday through
Wednesday with near-normal highs and scattered diurnal
convection.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
Uncertainty lingers over convective initiation this afternoon.
Recent mesoanalysis reveals quite a bit of convective
inhibition out there and with limited Cu development thus far.
Possible we may not get any convection to fire through the
afternoon.

Upstream, there is a convective system rolling southeastward
through Tennessee. Convectively induced impulse with that system
will be pressing down through the region tonight and we may get
showers/storms to develop at that juncture. But given the
uncertainty, I've removed any mention of showers/storms from the
terminal forecasts. Later updates may add convection back into
the terminal forecasts once convective trends become clearer.

Otherwise, VFR conditions this afternoon through Thursday
midday.

Extended Aviation Outlook: Mainly VFR. Brief flight
restrictions possible Saturday and Sunday due to a greater
coverage of showers and tstms.

&&

.MARINE...
Tonight: Southwest winds will persist in the coastal waters
through tonight...generally 10 to 15 knots with some higher
gusts. Seas will run 2 to 3 feet.

South to southwest winds will prevail Thursday through Tuesday.
For the most part, conditions will remain below advisory
criteria, though we could see some 25 kt gusts Thursday evening
due to a brief tightening of the gradient.
