Spartanburg, S.C. – Drivers across Upstate South Carolina should brace for delays Thursday as thunderstorms build during the afternoon and evening commute. Heavy rain and lightning could slow traffic along I-85, I-26, and other major roadways, creating hazardous travel just as the fall season begins.
According to the National Weather Service in Greenville-Spartanburg, showers may develop after midday Thursday with storms becoming more widespread after 2 p.m. A thunderstorm cluster is possible into Thursday night, raising the risk of localized flooding and dangerous lightning. Rain chances hold steady at 60 percent by evening, with temperatures near 84 before cooling into the upper 60s.
Residents in Spartanburg, Greer, and Boiling Springs should plan for delays on secondary roads and watch for ponding on low-lying streets. Power outages remain possible if storms intensify. Emergency officials recommend charging mobile devices, avoiding flooded areas, and delaying non-essential travel during peak storm hours.
Friday will bring another round of unsettled weather with scattered showers and storms likely, though coverage appears less widespread. Conditions ease slightly by Saturday as drier air filters in, but lingering showers may still disrupt outdoor events across the region.
While temperatures stay warm this week, dipping into the 60s overnight, an early preview of fall’s cooler side could appear next week. Forecast models hint at lows trending toward the mid-50s, offering the first true taste of seasonal change.
Warnings may be extended if storm intensity increases. Residents should monitor local alerts for updates as the week progresses.
