Area Forecast Discussion
National Weather Service Charleston SC
652 AM EST Sun Feb 22 2026

.WHAT HAS CHANGED...
The Aviation Section has been updated to reflect the 12Z TAF
issuance.

&&

.KEY MESSAGES...
- 1) Gusty winds expected across all areas late this morning
  into evening.

- 2) Sub-freezing temperatures return tonight and persist into
  the mid-week.

&&

.DISCUSSION...
KEY MESSAGE 1: Gusty winds expected across all areas late this
morning into evening.

A strong cold front is expected to move across the local area early
today, likely shifting off the South Carolina and Georgia coast by
mid-late morning and ending light to moderate rain/showers locally.
Strong cold air advection in wake of the front will promote ample
mixing into 35-40 kt low-lvl wind fields, favoring west/northwest
sfc winds gusting to around 30-35 mph this afternoon into early
evening. There remains a low risk for sfc gusts to approach 40 mph
during peak diurnal heating given the strength of cold air advection
and packed pressure gradient associated with high pressure building
in from the west, but the coverage/duration of event appears
limited and to fall just shy/short of Wind Advisory criteria for
a majority of the area. Should guidance and sfc obs trend higher in
regards to wind gusts this afternoon, a Wind Advisory could be
needed. Regardless, these winds should produce hazardous conditions
across Lake Moultrie (gusts up to 25-30 kt), which continues to
support a Lake Wind Advisory from noon to 9 pm today. Waves
between 1-2 ft are possible across the lake, largest along the
eastern lakeshore.

KEY MESSAGE 2: Sub-freezing temperatures return tonight and persist
into the mid-week.

As a cold front slides off the coastline this morning, expect cold,
dry surface high pressure to build into the region behind it. This
will yield a considerably colder airmass tonight into early next
week with well below-normal temperatures, widespread below freezing
temperatures Monday and Tuesday mornings, and wind chills dropping
into the upper teens to low 20s for some areas. NAEFS ESAT minimum
temperature anamolies hint at these below-average temperatures well
with values ranging from -3 to -4 for tonight through Tuesday
morning.

Temperatures will begin to fall this afternoon as breezy west-
northwesterly winds prevail and cold air advection continues through
tonight. By Monday morning, lows will reach the upper 20s inland and
low 30s along the coastline, but breezy winds will make it feel like
low to mid 20s area-wide, with upper teens possible inland. The
01Z.NBM minimum temps. forecast for Monday morning indicate a IQR
range of 2-3 degrees, reflecting a tightly clustered distribution
and reinforcing a high degree of confidence in the forecast. Also,
the 00Z.HREF indicates 80-90% chance of wind chill values dropping
below 20F on Monday morning for inland counties across southeast
Georgia (specifically Screven, Jenkins, Candler, Tattnall, Evans,
and Bulloch counties) and a Cold Weather Advisory will likely be
needed for these areas. Highs on Monday will struggle to reach 50F
(more than 15 degrees below normal for Feb.).

The coldest period is expected Monday night into Tuesday morning,
with lows in the low to mid 20s inland and upper 20s near the
coastline. Despite wind speeds being much lighter, wind chills will
still fall into the low to mid 20s, with a few upper teens possible
across inland counties of southeast Georgia. Additionally, the
01Z.NBM minimum temps. forecast for Tuesday morning indicate a IQR
range of 1-2 degrees, reflecting a tightly clustered distribution
and reinforcing a high degree of confidence in the forecast again.
Another Cold Weather Advisory may be warranted for portions of
southeast Georgia. Highs on Tuesday will moderate slightly, reaching
into the low to mid 50s.

&&

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
CHS/JZI: TEMPO IFR conditions are possible between 12-13Z this
morning before a cold front shifts offshore. Conditions will
quickly improve to MVFR for a few hours, then to VFR by around
15Z. Gusty west/northwest winds will follow late morning and
persist through the afternoon, peaking between 25-30 kt mid
afternoon. Gusty winds should persist through much of the
overnight, but will gradually decrease to the 15-20 kt range
through 12Z Monday.

SAV: TEMPO MVFR conditions are possible between 12-14Z this
morning, but will quickly improve to VFR following the passage
of a cold front. Gusty west/northwest winds will follow late
morning and persist through the afternoon, peaking around 30 kt
mid afternoon. Gusty winds should persist through much of the
overnight, but will gradually decrease to the 15-20 kt range
through 12Z Monday.

Extended Aviation Outlook: VFR.

&&

.MARINE...
Today and Tonight: A strong cold front will move across the area
early this morning, likely shifting offshore after daybreak and
bringing increasingly hazardous marine conditions across local
waters as strong cold air advection post front promotes low-lvl
mixing into 40-45 kt 1000mb geostrophic winds. Gale Warnings remain
in effect for all nearshore and offshore waters this afternoon into
early Monday for gusts up to 35-40 kt at times. A Small Craft
Advisory remains in effect for the Charleston Harbor this afternoon
and tonight as well.

Monday through Thursday: Marine conditions should gradually improve
to below Small Craft Advisory thresholds late morning Monday through
Monday night as high pressure builds across the region through mid-
week. However, winds and seas could increase/build to near Small
Craft Advisory levels mid-week, well ahead of large trough
approaching the region late week.

Sea fog: Patchy fog is possible across nearshore waters, including
the Charleston Harbor, until a cold front shifts offshore shortly
after daybreak. Ongoing rain/showers should limit a true sea
fog event, but vsbys could become reduced to 1-3 NM at times
early morning.
