Area Forecast Discussion
National Weather Service Charleston SC
716 AM EST Thu Feb 13 2025

.SYNOPSIS...
A cold front will push through the region this afternoon. This
boundary is expected to stall just south of the region on
Friday, lifting back north as a warm front Friday night into
Saturday, with a stronger cold front likely to impact the area
on Sunday.

&&

.NEAR TERM /THROUGH TONIGHT/...
At sunrise: The leading edge of the band of showers and isolated
thunderstorms is just starting to move into Jenkins County.
Watching the band upstream overnight, it does have a history of
producing some gusty winds with several observation sites
measuring gusts of 35-45 knots. No change to the severe weather
potential which is mostly concentrated in southeast GA south of
I-16. This area stands the best chance to destabilize
sufficiently to yield damaging wind gusts. Also of note, there
is some subtle veering of the wind profile, and a low end
tornado threat can't be ruled out. The main time period of
concern is still roughly 9am-1pm, though it can't be ruled out
prior to 9am as upstream convective elements reach Tattnall and
Candler counties.

Today and tonight: Aloft, a broad upper-level low situated over
northern Ohio/Lake Erie will continue to move northeastward and
an associated cold front trailing southward across the
Bluegrass will continue to move eastward towards the forecast
area and is expected to reach the western portion of the
forecast area by late morning. A broken line of organized
storms will develop ahead of the front and support enlarged
hodographs within a moist/weakly unstable warm sector. While the
shear and dynamics are impressive, the instability remains
marginal. Surface dewpoints ahead of the front are in the upper
60s which is contributing to MUCAPE values near the 275-500 J/kg
range. SPC has put our southern region in a MRGL risk, which
seems reasonable. The primary hazard will be damaging winds,
although an isolated tornado cannot be ruled out over SE GA
especially in the late morning. PWATs range from 1.7-1.8", which
is near the daily maximum according to SPC climatology.
Generally rainfall amounts across the area range from 0.5 inches
to 0.75 inches, with the highest amounts across southeastern
GA. Temperatures Thursday night post-FROPA will drop into the
40s across the region and a strong surface ridge begins to build
in from the northwest.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
A frontal boundary will linger to the south of the region on Friday
as surface high pressure briefly builds into the area from the
north. Southwesterly flow will prevail aloft as a large scale trough
over the western CONUS begins to trek eastward. Despite plentiful
sunshine on Friday temperatures will be a few degrees below normal,
only reaching into the mid to upper 50s, with a few locations across
southeastern GA reaching 60. Overnight lows will dip into the upper
30s across far inland zones and mid to upper 40s along the coastal
counties. The frontal boundary will begin to push northward as a
warm front Friday night into Saturday morning, with the forecast
area well within the warm sector for most of Saturday. High
temperatures will reach into the low to mid 70s as a result.
Scattered showers will be possible Saturday afternoon as moisture
begins to infiltrate the region ahead of the approaching cold front
from the west. PWATs will increase from around 1" Friday night to
~1.4" by Saturday afternoon. Lows on Saturday night will be very
mild, in the low 60s, more akin to the normal highs for this time of
year.

Sunday will be another active day as a cold front pushes through the
region. A mid-level trough will continue its trek across the CONUS,
passing over the southeastern states on Sunday. A line of showers is
forecast to push through the region, with rainfall totals generally
around 0.5 inches. Models have backed off on the amount of
instability across the region and therefore the thunderstorm chances
have decreased. The current forecast does not explicitly mention
thunder, however it cannot be completely ruled out.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
The aforementioned cold front will clear the forecast area on Sunday
night, with high pressure building in behind it. Post-FROPA
temperatures on Sunday night will plummet into the 30s across all
locations, with low 40s along the beaches. Clear and cooler
conditions are expected on Monday as high pressure builds in, with
high temperatures only reaching into the mid to upper 50s. Another
cold night in the 30s on Monday night before temperatures begin to
warm slightly as the center of high pressure meanders closer to the
forecast area. A low pressure system is forecast to develop in the
northern Gulf early in the week, impacting the local area mid-week
and bringing the next chances of rain.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
The 12z TAF period begins VFR conditions at KCHS and KSAV, but
IFR ceilings have been quite persistent at KJZI. IFR conditions
will be possible at KSAV and KJZI for the next few hours before
a frontal band of showers and isolated embedded thunderstorms
pushes into the area. We currently have showers getting into the
terminals around 14z, with the main time period of concern being
15-18z. The best chance for thunderstorms will be at KSAV, where
a TEMPO for TSRA has been included. We certainly can't rule out
thunder at KCHS and KJZI, but the probability is definitely
lower. This line of showers and storms has a history of
producing gusts into the 35-45 kt range and we have tried to
advertise some enhanced gusts in the TEMPO groups. The band
should shift off the coast by the mid afternoon hours. A period
of MVFR ceilings could occur in the wake of the band but
shouldn't be long-lived. Skies will gradually clear out
overnight and winds will pick up late as the high builds in and
north to northeast flow surges in.

Extended Aviation Outlook: Flight restrictions are possible on
Sunday associated with showers from a passing cold front.

&&

.MARINE...
Thursday and Thursday night: A strong cold front is
expected to push through the waters during the later afternoon
and evening, then generally east and south of the waters before
midnight going into Friday. Ongoing SCA conditions for AMZ350
and AMZ374, mainly for seas around 6 feet, should briefly drop
below SCA by late afternoon all waters. A line of showers and
possible thunderstorm will occur as the front pushes through.
Locally high wind gusts are possible with any of the
aforementioned thunderstorms. By Thursday night, a strong high
pressure will build from the northwest, with increasing NNE
winds, and all marine zones will be back into SCA criteria, with
seas building back around 6 feet 20nm offshore and beyond.

Friday through Tuesday: A warm front will lift northward Friday
night into Saturday, with a cold front pushing through the region on
Sunday. High pressure will build into the marine waters through mid-
week. Multiple marine hazards will be present this weekend, mainly
associated with the cold front on Sunday. Small Craft Advisories
will be ongoing across all waters outside of the Charleston Harbor
on Friday as some 6 ft seas linger. SCAs across the nearshore waters
should expire Friday night, with the 20 to 60 nm offshore GA waters
lasting into early next week as seas remain elevated. On Sunday
winds are forecast to surge across the marine waters, gusting to 25
knots across all waters. Additionally, gusts to gale force will be
possible in the Charleston nearshore and 20 to 60 nm offshore GA
waters. A Gale Watch may be necessary. Conditions will rapidly
improve into Monday and Tuesday.
