Charleston Weather Discussion

The latest forecast and discussion for the Charleston, SC metro area

Tuesday: Scattered storms in the afternoon; coverage ticks up mid-week

Jared Smith / August 24, 2026 at 6:06 PM

Tuesday will be a lot like Monday was, it looks like, with lows in the mid-70s yielding to highs in the low 90s in the afternoon. With the persisting stationary front to our west and the afternoon seabreeze, we can expect generally scattered thunderstorms to develop once again in the afternoon. Not everyone will see a storm, but those that do could see heavy downpours and even some severe weather, with damaging wind gusts the main concern.
