Area Forecast Discussion
National Weather Service Charleston SC
711 AM EDT Sun Jun 8 2025

.SYNOPSIS...
Active weather pattern continues as multiple upper level
disturbances impact the region. A few storms may become strong
to severe today and Monday. Otherwise, expect a cold front to
stall across the region mid-week, causing daily chances for
showers and storms to continue.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today: Aloft, the pattern will take on a bit more cyclonic
curvature as a shortwave moves across the OH and TN valleys and
becomes aligned along the spine of the Appalachians. At the
surface, a front will stretch across central VA and NC, the SC
Upstate and north GA. This will place the forecast area within a
hot and humid airmass once again, with a severe weather threat
accompanying afternoon and evening thunderstorms. Hi-res model
solutions are quite varied with the potential evolution of
convection later today. Each solution and each model run seems
to be trying to figure out which upstream convective feature to
latch onto, as well as the timing and eventual track of these
features. So, there isn't a lot of confidence in the specific
timing and placement of afternoon and evening thunderstorms, but
there is decent agreement regarding the near storm environment.
Overall, MLCAPE values of 2,000-2,500 J/kg are expected with
uni-directional wind profiles and 30-40 knots of mid- level
flow. DCAPE values in the 800-1,200 J/kg range also seem likely,
meaning that the primary severe threat will be damaging wind
gusts. Lapse rates also look sufficient to yield at least a low
end hail threat, but wind is still the primary concern. The
forecast features rain chances and convection coverage
increasing first inland around 1-2 pm, then pushing toward the
coast through the late afternoon and early evening hours. The
main severe time period is generally considered to be 2-8 pm.
Temperatures aren't expected to be quite as warm as Saturday,
but still most of the area will reach the low 90s with dewpoints
in the low to mid 70s. This would yield max heat index values
of 100-104 degrees, primarily along the coastal corridor.

This evening and tonight: Afternoon convection should shift off
the coast early this evening. Thereafter, we should only see
isolated shower and thunderstorm development into the early
morning hours, gradually diminishing through sunrise Monday.
Another warm and muggy night is expected, with lows falling into
the low to mid 70s.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
Upper level trough deepens across the central CONUS Monday, as
a stacked low strengthens over Michigan. Meanwhile, at the sfc,
will see the attendant cold front push eastward across the Ohio
River Valley, with a secondary front ahead of this feature
progged to stall out across our area Monday afternoon. Given the
increase in cloud cover throughout the day, only have highs
rising into the upper 80s. Nonetheless, with dewpoints in the
low to mid 70s, will still have a fairly juicy atmosphere to
work with. Latest soundings showcase ample CAPE (upwards of 2000
J/kg), 0-6 km bulk shear up to 30 kt, DCAPE between 500-1000
J/kg, and mid-level lapse rates near 7 degC/km. These parameters
would suggest that any severe storm would be capable of
producing damaging winds (58+ mph), isolated large hail, and
brief heavy downpours. Thus, we encourage you to remain weather
ready and have multiple ways to receive warnings. In terms of
timing, current CAMs show convection blossoming across our area
as early as 2 PM, though the better chances look to occur later
in the afternoon as the sea breeze moves inland and more diurnal
heating takes place. Storm mode looks to be fairly discrete,
though some CAMs hint at the possibility of linear development
as the afternoon goes on.

Expect the aforementioned upper level trough to continue its
journey eastward Tuesday, sending its attendant sfc cold front
closer to the region. Should see the stalled boundary gradually
push offshore through the afternoon hours as the front
encroaches upon the region Tuesday evening. Similar to Monday,
look for renewed chances for showers and storms to return ahead
of the boundary.

Upper level flow turns quasi-zonal heading into Wednesday, with
modest ridging then progged to briefly build overhead through
the late afternoon. With the aid of sfc high pressure, should
see fairly dry conditions prevail during the morning hours,
before diurnally driven showers return that afternoon. Highs
during this time look to remain in the upper 80s to low 90s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
Active weather pattern continues for the remainder of the
extended period as a stationary front holds tight overhead. As
such, expect typical summertime convection to be possible daily,
with better chances occurring in the late afternoon/evening as
the seas breeze moves onshore. Otherwise, look for highs in the
upper 80s to low 90s to remain common, with overnight lows
generally in the low 70s.

&&

.AVIATION /11Z SUNDAY THROUGH THURSDAY/...
The 12z TAF period begins with VFR conditions in place at KCHS,
KJZI, and KSAV. There is a low end chance we could see a brief
period of MVFR or even IFR ceilings at KSAV between 12-14z, but
we haven't added anything to the TAF at this point. Will
continue to monitor satellite data and surrounding observations.
Attention then turns to the afternoon for a couple of forecast
issues. First, winds will again be westerly and breezy for much
of the day. Frequent gusts around 20 knots are expected.
Finally, thunderstorms are again a concern though timing is low
confidence. Generally speaking, the best time for thunderstorm
impacts appears to be from mid afternoon through the early
evening hours. For now, we have maintained VCTS at all 3 sites
beginning around 20-21z and continuing through 00-01z. We will
work to refine timing and more specific impacts with future TAF
issuances.

Extended Aviation Outlook: Typical summertime convection
pattern will bring periodic flight restrictions through early
next week.

&&

.MARINE...
Today and tonight: Another round of elevated southwest flow is
expected across the local waters today and through the evening.
Wind speeds should mostly peak in the 15-20 knot range, though
we could again see some gusts up to 25 knots in the Charleston
County waters and in Charleston Harbor. Current thinking is that
conditions will remain just below Small Craft Advisory
criteria, but this will need to be monitored through the day.
Seas should average 2-4 feet. Also of note, inland thunderstorms
are expected to push to the coast and then out across the
coastal waters late this afternoon and into the evening. These
thunderstorms could be strong enough to produce strong wind
gusts and Special Marine Warnings could be needed.

Monday through Wednesday: Expect west south-westerly winds to
prevail throughout the period with Bermuda high pressure
offshore. Winds could become a bit breezy in the afternoon and
evening as the sea breeze moves inland. Gusts could approach 25
kt at times, mainly across the Charleston County nearshore
waters Monday and Tuesday. Seas during this time should largely
range between 2 to 4 feet, with the Charleston County nearshore
waters and outer Georgia waters perhaps approaching 5 feet prior
to daybreak Tuesday. For now conditions remain marginal, but
will continue to monitor trends in the event that SCA are
needed.
