Charleston drivers may enjoy a few more sunny days before storms return late this weekend, bringing potential slowdowns on I-26. Sunshine dominates Thursday through Saturday, but forecasters warn showers and thunderstorms could develop as early as Sunday afternoon.
According to the National Weather Service in Charleston, high pressure will keep skies clear through Saturday, with temperatures climbing near 88 degrees. Conditions shift Sunday when a 30 percent chance of storms enters the forecast, with rain most likely after 2 p.m. Motorists should plan for wet pavement and heavier traffic if storms roll through during peak travel hours.
Friday night football games and outdoor events look safe, with mostly clear skies and comfortable overnight lows in the low 70s. However, weekend beachgoers should keep an eye on the radar by Sunday afternoon, especially along Folly Beach and U.S. 17, where brief downpours could cause ponding.
Early next week, storm chances climb higher. By Monday, scattered showers are possible across Charleston County and beyond, with rain likely during the afternoon commute. Tuesday and Wednesday carry a 40 percent chance of storms each day, signaling a wet start to the workweek.
Residents should take advantage of the dry stretch through Saturday to prepare for unsettled weather ahead. Keep umbrellas handy, allow extra travel time on major roadways, and monitor updates as storm chances increase by Sunday night.
