Area Forecast Discussion National Weather Service Charleston SC 127 AM EDT Fri Jun 13 2025

SYNOPSIS
A series of upper level disturbances will affect the area through the weekend. Meanwhile, high pressure will expand over the western Atlantic and persist through next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
Early this morning: Lingering evening convection has dissipated and we now turn our attention to the coast and the coastal waters which will likely be the primary area for overnight showers and thunderstorms. Through sunrise, this activity should mostly just be showers, producing brief periods of rainfall. Any fog concerns are mainly for the SC Midlands, but could try to sneak into the interior in the next few hours. Warm and humid conditions will continue, with lows forecast to fall into the low to mid 70s.

SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY/
A somewhat more active weather pattern will continue through Sunday across the Southeast. While the area will be on the western side of Atlantic high pressure, the upper ridge axis will be far enough offshore to allow numerous shortwaves to ripple through the area, providing an additional focus for convection. The greatest coverage will be during daytime hours when greater instability exists, however the airmass should maintain enough theta-e to support a few showers or tstms through the overnight hours as well. The convective parameters do not look particularly impressive so we don't expect a widespread threat for severe weather. Nevertheless, given the season, we can never completely rule out an isolated severe thunderstorm with damaging winds and/or large hail. Highs will slowly warm each day with values in the low 90s in spots by Sunday. Heat indices should remain below advisory criteria.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
The upper ridge axis is expected to shift west early next week with a deep layered ridge building over the Southeast.
Precipitation coverage is expected to move back to a more typical summertime pattern with mainly scattered afternoon/evening showers and tstms. High temps are expected to climb toward the middle of next week, with heat indices pushing well above 100 each afternoon. We could need Heat Advisories for portions of the SC Lowcountry and southeast GA Tuesday through Thursday where heat indices rise above 108 degrees.

AVIATION /06Z FRIDAY THROUGH TUESDAY/
The 06z TAF period begins with VFR conditions at KCHS and KSAV, but MVFR ceilings in place at KJZI. The first concern is for showers to soon move into the vicinity at KJZI. These showers could bring brief rainfall as well as MVFR ceilings. This activity should miss KSAV, but could come closer to KCHS through about 10z. Then attention turns to afternoon thunderstorm potential. Thunderstorms should start developing around 17-18z and could at least in the vicinity at all 3 TAF sites.
Confidence in direct impacts is low, but if the terminals take a direct hit from a thunderstorm expect a brief period of heavy rain and MVFR or IFR conditions.

Extended Aviation Forecast: Brief flight restrictions are possible in showers and thunderstorms each day, mainly in the afternoon.

MARINE
Tonight: Atlantic High pressure will yield SE winds this evening, veering to the S overnight. Sustained winds should be 5-15 kt. Though, there could be higher gusts along the land/sea interface. Seas should average 2-3 ft.

Friday through Wednesday: Conditions should remain below Small Craft Advisory criteria.

CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...None.
