Spartanburg, South Carolina – A surge of summer heat and building thunderstorm chances will challenge Spartanburg residents starting Monday, with a series of stormy afternoons expected all week. Highs near 96°F and a heat index approaching 100°F set the stage for scattered thunderstorms, with localized heavy rainfall and gusty winds posing real risks along I-85 and across the city.

Residents should stay weather-aware, especially during the Monday evening commute and any outdoor activities, and keep phones charged for alerts.
City impacts will focus on main corridors such as I-85, I-26, and major roads across Spartanburg County.
