Area Forecast Discussion National Weather Service Charleston SC 750 AM EST Sat Feb 28 2026
WHAT HAS CHANGED
Key Message 1 has been updated to change the timing to this morning.
KEY MESSAGES
- 1) Areas of low stratus and fog likely this morning.
DISCUSSION
KEY MESSAGE 1: Areas of low stratus and fog likely this morning.
As of midnight a cold front is located to the south of the forecast area. GOES satellite imagery shows a large area of low stratus working southwards across the the forecast area, with ceilings less than 1k ft across most of the region. Additionally fog has developed in some spots as dew points remain elevated.
Generally visibilities will be between 1 and 3 miles through the overnight period, however brief drops to less than 1 mile will be possible. Both the 00Z NBM and HRRR are very unsupportive of the fog becoming dense, with probabilities only around 20% of visibilities less than 1 mile. Therefore, a Dense Fog Advisory is unlikely tonight.
AVIATION /12Z SATURDAY THROUGH WEDNESDAY/
KCHS/KJZI will initialize with IFR cigs for the 12Z TAFs, with MVFR cigs at KSAV. Conditions will slowly improve today, with VFR expected by the afternoon hours.
Extended Aviation Outlook: The next chance of flight restrictions is late Sunday into Monday due to a passing cold front.
MARINE
Areas of fog are still possible early this morning, however webcam observations show that the fog is no longer dense and the Marine Dense Fog Advisory in effect for the Charleston Harbor has been canceled. Patchy fog will linger this morning, however is expected to clear up by late this morning/early afternoon.
A dry cold front is expected to push through the region early next week, bringing elevated seas and gusts. Small Craft Advisories are likely across all waters, including the Charleston Harbor, from Monday into Monday night. NBM probabilities of gusts >34 kts are around 35% across the Charleston nearshore waters, so a Gale Watch/Warning is possible.
CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...None.
