Charleston Weather Discussion

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

Forecast: A stormy couple days ahead, but quieting down a bit for the Fourth

/ July 1, 2025 at 6:19 PM

A cold front will draw nearer to the Lowcountry on Wednesday before stalling out, which will help kick up the risk for thunderstorms especially during the afternoon and evening hours. It won’t rain all day, but many of us should measure some rainfall as storms push across the area from west to east through late night. Temperatures in the mid-70s will warm to the upper 80s to around 90°. There’s a chance our 18-day streak of 90°+ highs will come to an end thanks to the proliferation of cloud cover, showers, and thunderstorms on Wednesday, but we will see. Regardless, expect a steamy and eventually stormy day across the metro; be ready for rain to cause some slowdowns.

Thursday is looking a little better, though some storms could linger midday. But drier air will be moving in, and we should see improving conditions by evening. It’ll be another warm day, with highs returning to the 90s in the afternoon after another mid-70s start.
