Spartanburg, SC – Residents across the Upstate should prepare for a shift in the weather pattern this week. A hot and sunny stretch will be briefly interrupted by potential thunderstorms on Thursday, just in time for Juneteenth celebrations.

According to the National Weather Service in Greenville-Spartanburg, there is a chance for showers and thunderstorms developing after 3 p.m. on Thursday.
