Columbia, South Carolina — A widespread rain event is impacting much of central and eastern South Carolina this Wednesday, with the heaviest rainfall expected across the eastern Midlands and Pee Dee regions. According to the National Weather Service in Columbia, rain coverage and intensity increased during the morning hours and may become moderate to heavy at times, especially east of Columbia.
Forecast guidance indicates that rainfall totals exceeding one-half inch are most likely in the eastern Midlands and Pee Dee, while amounts may decrease sharply farther west toward the Upstate. Motorists traveling along Interstates 20, 26, 77, and major secondary roads should anticipate periods of reduced visibility, ponding of water, and slower travel conditions through much of the day.
As colder air gradually filters southward this evening, precipitation is expected to taper off from west to east. However, forecasters note a low but notable chance of freezing drizzle developing overnight across the northern Midlands and Pee Dee. If this occurs, bridges, overpasses, and elevated roadways could briefly become slick due to minor ice accumulation or patches of black ice.
While widespread icing is not expected, even a thin glaze can create hazardous driving conditions, particularly during late-night and early-morning travel. Drivers are urged to reduce speed, increase following distance, and use caution on untreated surfaces.
Temperatures tonight will hover near freezing in northern areas, increasing the risk of refreezing where roads remain wet after rainfall ends. Conditions should gradually improve Thursday morning as precipitation exits the region and temperatures stabilize.
Residents are encouraged to stay weather-aware and monitor updates, especially if traveling late tonight or early Thursday. For the latest forecasts and road condition updates, visit weather.gov/cae or local transportation resources.
