Columbia, South Carolina – Storms are expected to return to the Midlands by late Friday, putting weekend plans and road safety across Columbia at risk. Rain and isolated thunderstorms could develop after 11 a.m. Friday, bringing slick roads and poor visibility—especially on I-26, U.S. 378, and other major corridors.

According to the National Weather Service in Columbia, a 30% chance of thunderstorms begins midday Friday, with additional showers continuing through Saturday. The agency warns that locally higher rain totals are possible with thunderstorms, especially in Richland and Lexington counties. Weekend events and travel may be impacted as rain chances climb to 60% by Saturday night.

Friday’s high near 89°F, combined with increasing moisture, could enhance storm intensity. Drivers are urged to slow down during heavy rain and monitor alerts for sudden changes in weather conditions. Outdoor activities on Friday afternoon and Saturday should have indoor backup plans.
