A frost advisory is active across much of South Carolina, including Columbia, Florence, and surrounding areas, through Thursday morning, March 20, 2026, with temperatures dipping near or below freezing from midnight to around 9 a.m.
Impacts and Precautions
Frost on windshields, bridges, and roads could create slick spots and reduce visibility during the commute, especially in rural spots. School districts may delay openings or close—check local announcements early, as no widespread decisions were out by Wednesday evening.
Protect plants, let vehicles warm up, and drive cautiously. This late-spring chill fits recent cold snaps in the Upstate and Midlands you’ve been tracking alongside local crime updates. NWS Columbia has the latest map.
