Area Forecast Discussion
National Weather Service Charleston SC
420 PM EDT Sat Jul 22 2023

.SYNOPSIS...
A weak stationary front will remain inland through early next
week before dissipating. Weak high pressure will then prevail.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
A weak area of surface low pressure will reside over the coastal
NC/SC border. It's associated cold front strung south near the
coast, then arching back around I-16 oriented nearly east-west
across southern GA and southern AL. A sharp gradient exists
across our southeast GA counties noted by dewpoints in the upper
60s to low 70s north of I-16 and mid to upper 70s south.
Ongoing convection to our south was rather impressive earlier
where a highly unstable and moist environment exists. However,
due to the location of the front, conditions are less favorable
for deep convection in our forecast area. A large area of
showers with embedded thunderstorms looks to push northeast
through the evening, weakening as the environment becomes less
unstable due to the overcast skies that have overtaken southeast
Georgia.

Additionally, isolated showers and storms will develop across
the SC Midlands near the area of low pressure where surface
convergence is most prevalent. There is potential for a stronger
storm to develop across the Charleston-Tri County before
overcast skies soon reach the area. Zonal flow aloft with some
indication of rippling shortwaves could provide some additional
forcing through the night. It looks as though convection across
the northern tier should cease around midnight, however model
guidance has been rather inconsistent and across the board
today, so kept slight chance POPs in through late tonight. With
deep westerly winds in place overnight behind the front,
slightly cooler temperatures are expected (mainly inland) with
lows forecast to range from the low 70s inland to the mid/upper
70s along the immediate coast.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
Sunday: A broad cyclonic flow will linger across the Southeast U.S.
and Deep South into Sunday as the East Coast longwave trough
persists and even deepens a bit. At the surface, a weak stationary
front will remain just north of the area with a subtle frontal wave
meandering over the South Carolina Midlands. A warm, moist
environment will remain in place across Southeast South Carolina and
Southeast Georgia within the warm sector. Guidance is similar in
keeping a well defined lobe of channeled vorticity hugging the coast
and stretching southwest into the Florida Panhandle as the longwave
trough deepens a bit to the west. The combination of modest
instability and quasi-geostrophic forcing in the vicinity of both
the area of channeled vorticity and the right entrance region of
southwest-northeast oriented jet stream to the northwest should
yield a pretty good coverage of showers/tstms from mid-afternoon
into the evening hours as noted by a large number of the CAMs and
global models.

There is some concern that dewpoints could mix out in the 60s and
temper the degree of mixed-layer instability somewhat away from the
coastal corridor, but given the degree of UVVs noted in model cross
sections, the setup looks pretty favorable for the development of
showers/tstms even if only marginal levels of instability develop.
Pops were raised to 50-80%, highest roughly along/east of the I-95
corridor where the better juxtaposition of richer low-level moisture
and upper forcing will be found. With a ribbon of PWATs in excess of
2" in place, there will be a risk for locally heavy rainfall and
urban/minor flooding of low-lying and poor drainage areas as intense
hourly rainfall rates could occur.

Convection will slowly wane during the evening hours with at least
some low-end chance for measurable rainfall persisting into the
early morning hours Monday. Highs will warm into the upper 80s/lower
90s prior the onset of rain with overnight lows ranging from the
lower 70s inland to the upper 70s at the beaches.

Monday and Tuesday: The pattern will begin to switch to a more sea
breeze dominated convective regime Monday into Tuesday as dewpoints
mix out across the interior and mid-level dry air vertically
expands. Model cross sections show mean RH values in the 700-400 hPa
layer dropping to <10% both days with even some broad subsidence
noted Monday afternoon as the main vorticity channel shifts farther
offshore. Convection should generally remain confined to and near
the afternoon sea breeze where low-level moisture could help augment
instability. Pops 20-30% Monday and 20% Tuesday were highlighted
across the coastal corridor with pops <10% across the far interior
both days. Highs will warm into the lower 90s Monday with lower-mid
90s Tuesday away from the beaches. Lows Monday night will drop into
the lower 70s well inland to around 80 at the beaches.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
What is left of the lingering mid-level weakness across the
Southeast U.S. will steadily fill through the week as subtropical
ridging takes hold. The chances for mainly afternoon/evening
showers/tstms will be largely confined to isolated category given the
building heights aloft and weak sea breeze convergence. The
identification of the mesoscale features that could locally augment
the convective regime is impossible to pin down this far out, so
pops will be capped at 20% for now. Temperatures will be near
seasonable levels for the end of July with coastal heat indices
generally peaking around 105 each afternoon.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
Showers and thunderstorms will again impact the area later this
afternoon and evening. Guidance shows more coverage across
southeast Georgia where there is higher confidence KSAV will
receive direct impacts from convection. Thus, a TEMPO was
created for TSRA and MVFR conditions at KSAV this evening.
However, KJZI and KCHS have mention of VCTS as models show more
isolated to scattered coverage across southeast SC. This
continues until a few hours after midnight similar to previous
nights where activity could take until around midnight before
winding down.

Extended Aviation Outlook: Impacts from showers/tstms are likely at
all three terminals for Sunday. Otherwise, there are no concerns
through the remainder of the week as showers/tstms should largely
remain in the isolated category.

&&

.MARINE...
Tonight: High pressure in the Atlantic and a weak front inland
will support SW winds between 10 to 15 kt, shifting more
westerly by morning. Seas should average 2-3 ft. Later this
afternoon and into the evening scattered thunderstorms are
forecast to push across the nearshore waters. A few storms may
produce wind gusts of 34 kts or greater. Marine Warnings could
be needed.

Sunday through Wednesday: There are signals that convection Sunday
afternoon and evening could help enhanced southwest winds across the
local marine area. It is unclear whether these winds will be
directly tied to convection, but at least some influence is
expected. Wind speeds were capped at 15-20 kt with gusts holding
below Small Craft Advisory levels for now; however, an advisory may
be needed if these model trends continue. Otherwise, south to
southwest winds will prevail for much of the period with typical sea
breeze enhancements near the beaches and Charleston Harbor each
afternoon. Beyond Sunday, speeds will largely remain <15 kt with
seas 1-3 ft.
