Area Forecast Discussion
National Weather Service Charleston SC
756 PM EDT Sat Mar 14 2026

.WHAT HAS CHANGED...
The Aviation Section has been updated for the 00Z TAF issuance.

&&

.KEY MESSAGES...
- 1) Scattered thunderstorms expected Sunday with an isolated
  severe threat possible.

- 2) A strong cold front will pass through southeast GA and
  southeast SC on Monday bringing the potential for severe
  thunderstorms, very gusty winds outside of storms, and brief
  periods of moderate to heavy rainfall.

- 3) Frost/freeze is possible Monday night and Tuesday night.

&&

.DISCUSSION...
KEY MESSAGE 1: Scattered thunderstorms expected Sunday with an
isolated severe threat possible.

As high pressure situates itself across Georgia and the Carolinas, a
coastal trough sharpening offshore will lift northwards across the
region with an associated warm front tomorrow morning. As this warm
front lifts across the region, a plume of moisture will surge into
area with it as PWATS range from 1-1.5 inches. This will yield a
supportive environment for scattered coverage of showers and
thunderstorms throughout tomorrow. 12Z HREF indicates convection
initiating offshore early on Sunday morning, and then slowly moving
northwestward into the rest of region throughout the morning. Shower
and thunderstorm activity will likely persist through the evening
before another system tracks towards the region. The near-storm
environment continues to look interesting with the warm front in the
vicinity as MLCAPE values range from 1000-1500 J/kg and 0-1km rises
near 30 kt. 12Z HRRR forecast soundings show some decently veering
profiles in the afternoon, which could be an indication of a low-end
tornado threat (esp. for interior southeast Georgia). SPC has
highlighted the region in a marginal risk (level 1/5) for severe
weather tomorrow, with damaging winds gusts being the primary risk
for tomorrow. While the environment lacks the magnitude of the
severe weather threat on Monday (discussed in Key Message 2), it
will bear watching as a sneaky severe threat.

KEY MESSAGE 2: A strong cold front will pass through southeast GA
and southeast SC on Monday bringing the potential for severe
thunderstorms, very gusty winds outside of storms, and brief periods
of moderate to heavy rainfall.

Severe Thunderstorms: As a large and deepening mid-lvl trough ejects
out of the Ohio River Valley and tracks towards the Mid-Atlatnic on
Monday, an associated strong cold front will track into the region
late Monday morning and shift off the coastline by mid-afternoon.
Expect some isolated convection ahead of this front early Monday
morning, followed by linear convection along the front. It's
possible a couple of these isolated cells in the early morning could
become severe fairly quickly as the near-storm environment appears
favorable for it. However, the greatest concern remains to be in the
afternoon as the front nears, and daytime heating yields a high
degree of destabilization. The forecast area will be positioned
within the warm sector ahead of the front with temps. warming into
the mid to upper 70s an dewpoints rising into the upper 60s,
yielding MLCAPE values above 1000 J/kg. Additionally, the ambient
wind field looks rather impressive with 0-6km shear ~50kt and 0-3km
shear ~40kt in the afternoon. Mid-lvl lapse rates may be modest,
however sufficient low-lvl moisture and strong forcing should
compensate and allow for robust updraft development in the afternoon.
12Z HRRR forecast soundings show some indication of veering (esp. in
southeast South Carolina), but the majority display unidirectional
hodographs despite the magnitude of shear. Regardless, a tornado
threat still appears present ahead of the front and within the main
line of convection as the front passes through. There remains to be
some model disagreement between the timing of the front, however the
main line of convection should reach interior southeast Georgia by
late morning. Therefore, SPC has highlighted a majority of the
region in a slight risk (level 2/5) and a portion of southeast South
Carolina in an enhanced risk (level 3/5). Damaging wind gusts are
certainly the primary threat, followed by a couple isolated
tornadoes, and hail threat certainly being a distant third.

Gusty Winds: This will be the primary threat as the strengthening
wind field expands across the region ahead of the front on Monday
morning. Strong momentum aloft will easily mix to the surface on
Monday morning, allowing for strong non-thunderstorm wind gusts
through the morning and into the afternoon. Some wind gusts could
exceed 35 mph across the region, and therefore a Lake Wind Advisory
will almost certainly be needed, with even the possibility of a Wind
Advisory needed for a portion of the area.

Rainfall: Forecast precipitable water values are expected to reach
around 1.2-1.5 inches ahead of the front, which is well above
climatological normals for mid-March. This is an indication that the
atmosphere is capable of producing efficient rainfall rates within
thunderstorms, however these heavier bursts will likely be short-
lived given the expected forward speed of these storms. This will
reduce the overall threat of excessive rainfall. Rainfall amounts
range from 0.5-1.0 inches, with localized higher amounts possible
within training thunderstorms. Thus, at this time, the risk
for intense rainfall producing flooding appears rather low.

Residents across southeast South Carolina and southeast Georgia
should continue to closely monitor the forecast through the weekend
as details regarding timing, storm intensity, and hazards become
clearer as Monday approaches.

KEY MESSAGE 3: Frost/freeze is possible Monday night and
Tuesday night.

Cold high pressure will build across the region behind a cold front
shifting offshore Monday. An advection freeze is possible Monday
night, mainly for inland areas of Southeast GA and SC where temps
are forecast to dip into the lower 30s for at least a few hours
Monday night into Tuesday morning. The surface high is then
anticipated to settle over the area Tuesday, favoring winds that
decouple quickly under clear skies Tuesday evening. This should
favor a radiational cooling component away from the coast (where the
pressure gradient is weak) in addition to the cooler air mass
already in place, setting the stage for a fairly widespread frost
and/or freeze event as temps drop into the upper 20s inland to low-
mid 30s closer to the coast. Frost/Freeze headlines are likely for
both nights, with greatest impacts anticipated Tuesday night into
Wednesday morning. There is a lower risk for frost inland Thursday
night as temps lower into the mid 30s and a light northerly wind is
in place. However, areas or widespread frost appear less likely
during predawn hours Thursday compared to the previous mornings.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
VFR conditions will prevail at CHS/JZI/SAV terminals through 06Z
Sunday. There are some indications that flight restrictions are
possible at the terminals between 06Z-12Z tonight, with the
greater chance at SAV due to patchy fog developing in advance
of a warm front, but the window appears somewhat limited before
scattered showers develop by around daybreak Sunday. Flight
restrictions are then possible for showers developing across the
area as a coastal trough/warm front lifts north across the
region Sunday morning. PROB30 groups remain in place between
12Z-18/19Z Sunday for this activity, starting at 12Z at SAV and
14Z at CHS/JZI. Prevailing MVFR groups and TEMPO thunderstorms
could eventually be needed in the Sunday 14Z-19Z time range.
Thereafter, latest guidance indicates VFR conditions at all
terminals through 00Z Monday, prior to additional showers (and
possibly thunderstorms) occurring Sunday night.

Extended Aviation Outlook: Brief flight restrictions are possible
with showers and thunderstorms Sunday evening as the local area
becomes warm-sectored ahead of a cold front arriving Monday.
Greater chances for MVFR or lower conditions occur at all
terminals with showers/thunderstorms prior to and near the
passing front Monday. Gusty winds are also anticipated outside
of shower and/or thunderstorm activity at all terminals Monday.

&&

.MARINE...
Through Tonight: High pressure will give way to a coastal
trough/warm front shifting north across the area approaching
daybreak Sunday. Wind/seas are expected to remain well below
Small Craft Advisory levels during this period, but shower and
thunderstorm activity could develop across Georgia coastal
waters a few hours prior to daybreak, a few of which could be
strong near the northward lifting warm front Sunday.

Strong southerly winds will develop across local waters Sunday night
into Monday ahead of a cold front approaching the Southeast United
States early week. Solid Small Craft Advisory level conditions are
expected prior to and during cold fropa. Additionally, there is a
low-end potential for gale force wind gusts across nearshore SC
waters (including the Charleston Harbor) and outer Georgia waters
Monday. Small Craft Advisory conditions are expected to linger into
Tuesday morning/afternoon, before subsiding.
