Greenville, South Carolina – Temperatures climbing into the mid to upper 80s across the Upstate today could challenge record highs, but the summer-like warmth will be short-lived as a powerful cold front approaches with a risk of strong storms overnight into early Thursday.
According to the National Weather Service in Greenville-Spartanburg, the region will likely approach or exceed record high temperatures Wednesday afternoon before a line of showers and thunderstorms moves in late tonight into early Thursday morning. Some storms could become strong to severe, especially along the North Carolina mountains and foothills, where damaging wind gusts are the main concern.
Cities including Greenville, Spartanburg, Anderson, and Gaffney could see storms develop during the overnight hours and push east through the early Thursday commute. Travel along Interstate 85, Interstate 26, and U.S. 25 may be affected by heavy rain and sudden wind gusts as the cold front sweeps across the region.
Emergency managers recommend securing loose outdoor items this evening and staying alert for weather warnings overnight when storms are most likely to intensify.
Much cooler air will follow the front Thursday, with temperatures dropping significantly compared to Wednesday’s heat. Forecasters say additional updates may be issued if the severe storm threat increases overnight.
