Area Forecast Discussion
National Weather Service Charleston SC
111 PM EST Sat Feb 15 2025

.SYNOPSIS...
A warm front will lift into the area today. A strong cold front
will impact the area Sunday, followed by high pressure. Another
system could impact the area around the middle of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today: Latest surface analysis shows the coastal front/
inverted trough axis starting to move onshore with temperatures
along coastal SC/ GA rising almost 20 degrees in the past 2 hrs.
Isentropic lift associated with this front will keep the day
mostly cloudy. At the surface, remnants of a Cold Air Damming
(CAD) front remain from the shallow cool wedge, but will quickly
erode as the front pushes through the area. Northeasterly winds
quickly shift southeasterly as the front passes through.
Scattered showers are forecast to develop through the day in
response to the aforementioned isentropic lift and chance PoPs
were kept in the forecast for the morning through the afternoon.
Low QPF associated with these PoPs, with 0.1 inches or less by
the end of the day.

Tonight: The upper-level trough situated over the central CONUS
will traverse eastward and deepen overnight as an attendant cold
front approaches the forecast region from the west.
Southeasterly winds will begin to surge ahead of the front, and
conditions will become quite breezy overnight. Due to strong
southerly flow, lows will be 10 to 15 degrees warmer than the
night before, with lows in the upper 50s/low 60s.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY/...
Sunday: A strong cold front is expected to move through the area
along with a line of convection that will rapidly move across the
forecast area earlier in the day. Instability will be lacking with
SBCAPE just 100-300 J/kg at its peak, but deep layer bulk shear of
60-80 kt will be present. SPC continues with a MRGL risk for severe
thunderstorms for the entire area, mainly to account for the strong
shear and dynamics with the upper trough. We maintain slight chance
for thunder, and there still could be some stronger showers/storms
that produce strong/damaging straight line wind gusts, especially
between mid morning through early afternoon. Mild temperatures are
forecast, in the low/mid 70s, and breezy southerly winds ahead of
the front shifting to westerly in the afternoon. Wind gusts could
reach up to 35 mph most places, strongest along the SC coast where
40-45 mph are certainly possible. A Wind Advisory could be needed
for a few counties. Additionally, winds over Lake Moultrie could
peak around 35-40 kt which will eventually be covered by a Lake Wind
or Wind Advisory. By Sunday night, the front will be well east of
the area with strong arctic high pressure building from the
northwest. Temperatures will quickly drop with strong CAA well
underway. We are forecasting lows to plummet to the low/mid 30s west
of I-95, and upper 30s to lower 40s eastward to the coast.

Monday and Tuesday: High pressure will prevail at the surface along
with quasi-zonal flow aloft. Under sunny skies Monday, highs will
only reach the mid to upper 50s, and then rebound quickly Tuesday
back toward normal in the low to mid 60s. Monday night will be
another cold night with min temps in the low to mid 30s inland and
low to mid 40s along the coast.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Another strong cold front could impact the region Wednesday.
Still too soon to assess the severe potential, but looks to be
another high shear/low CAPE scenario with little in the way of
instability. Blended model guidance was quite high that far out
with PoPs, but collaborated forecast went with likely to low end
categorical. The main concern for this period will be the very
cold/arctic high pressure that will dominate at least through
the end of the week. Lows in the mid 30s to lower 40s Wednesday
night could then possibly drop into the mid 20s to lower 30s
both Thursday and Friday night, which would be colder than it
has been since last month.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Today: The coastal trough and associated warm front has moved
inland this afternoon with winds turning from the southeast
across the TAF sites. A mixture of MVFR to VFR cigs has been
occurring through the morning hours, with a change to
prevailing MVFR cigs forecast as low level saturation continues.
There have also been a continued uptick in shower activity
thanks to the isentropic upglide. This has been well forecast by
high res guidance, even though it has been slightly delayed.
Later tonight, the best isentropic upglide will likely move
north and east with showers first coming to an end at KSAV
followed by the Charleston terminals.

Tonight: An impressive low level jet is forecast to move
overhead of the terminals with 925 - 850 mb winds averaging 60
kt. Overnight, winds are generally expected to be 20 to 30 kt
as mixing remains limited, however have kept the mention of LLWS
in the TAFs to account for the above. Out ahead of these strong
low level winds, cigs will likely deteriorate to IFR then start
to rise again as the low level winds increase. No precipitation
is expected.

Sunday: A cold front will cross the zones in the morning with a
line of showers and possibly a rumble of thunder. Wind gusts of
30 to 50 kt are possible with the passage of this convective
line with some localized higher gusts. The line of showers will
then rapidly clear the coast late Sunday morning and be clear
of the TAF sites by 18z Sunday.

Extended Aviation Outlook: A cold front will impact the area on
Sunday. Flight restrictions are likely, with at least periods of
MVFR, possibly IFR CIGS. Gusty southerly winds ahead of the front on
Sunday, shifting to westerly in the afternoon, with gusts up to 30
kt. Showers and isolated thunderstorms possible ahead of and with
the front, with stronger showers possibly producing stronger wind
gusts. Then, generally VFR to prevail through early Tuesday night.
Another front could impact the area Wednesday with flight
restrictions possible.

&&

.MARINE...
Today and tonight: As high pressure shifts offshore overhead,
northeasterly winds quickly shift southeasterly as a warm front
lifts northward across Atlantic waters. With seas 5-7 ft in the
outer Georgia waters, a Small Craft Advisory remains in place.
Ahead of the approaching cold front, southeasterly flow surges
and the gradient really tightens up by the evening.
Expect southeasterly winds of 15-20 kt with gusts up to 25-30
kt at all marine zones. Small Craft Advisories issued for the
nearshore South Carolina and Georgia waters beginning at 7PM
tonight. In addition, a Small Craft Advisory issued for the
Charleston Harbor starting at 11PM tonight. Expect seas 4-6 ft
over the nearshore waters and 6-8 ft over the outer Georgia
waters.

Sunday through Thursday: A strong cold front will push across the
waters early in the day Sunday along with a line of quick-moving
convection and strong southwest winds. Gale Watches are in effect
for all marine zones, including the Charleston Harbor, Sunday
morning until Sunday evening. A few stronger showers/storms are
possible with dangerous gusts 50 kt or greater, mainly during the
mid morning and mid afternoon time frame. Seas look to peak around 6-
10 feet Sunday afternoon. The front then passes east of the waters
by Sunday evening, however Small Craft Advisory conditions are
likely to remain through Sunday night/early Monday. High pressure
will then build over the region Monday through Tuesday with no
highlights/concerns expected. High pressure will move east of the
waters Tuesday night and Wednesday ahead of yet another front.
Southerly winds increase during the end of the period, with the
increasing potential for Small Craft Advisories Thursday for 25 kt
gusts and 5-7 ft seas.
