| Area Forecast Discussion National Weather Service Charleston SC 444am EDT Fri Mar 13 2026 .WHAT HAS CHANGED... The Marine and Aviation sections were updated. .KEY MESSAGES... - 1) A strong cold front will bring rain, gusty winds, and the possibility of severe thunderstorms on Monday. - 2) Frost/freeze is possible Monday night and Tuesday night. KEY MESSAGE 1: A strong cold front will bring rain, gusty winds, and the possibility of severe thunderstorms on Monday. A strong upper trough will move toward the Appalachians Sunday night and Monday. A warm front will lift north Sunday afternoon and evening, potentially bringing some showers to the area. A strong cold front then sweeps through the area Monday afternoon and evening, bringing a fairly widespread band of showers and thunderstorms. Total Quantitative Precipitation Forecast currently looks to be around half an inch on average. Models show the potential for at least marginal instability which combined with strong low-level wind fields could result in some strong to severe thunderstorms. KEY MESSAGE 2: Frost/freeze is possible Monday night and Tuesday night. Following the passage of the cold front Monday evening, drastically cooler temperatures are expected through the middle of next week. Monday night and Tuesday night could see freezing temperatures across the interior portions of SC and GA. Winds will be too strong for frost Monday night, but Tuesday night we could see winds relax enough to allow for some frost formation, potentially closer to the coast where lows are just above freezing. Marine Through Tonight: Conditions across the coastal waters will steadily improve today as cold air advection wanes and the pressure gradient relaxes. The Gale Warning for the Georgia offshore waters expired at 5pm with a Small Craft Advisory now in effect until 3 PM. Advisories for all other nearshore legs are on track to expire at 9 AM. Saturday through Wednesday: Strong southerly winds will develop Sunday night into Monday ahead of a strong cold front. Solid Small Craft Advisory conditions anticipated, along with the potential for Gales across the Charleston nearshore waters due to 35 kt gusts Monday afternoon/evening.
