Daytime heating, along with sufficient atmospheric moisture and instability, combined with a nearly stationary surface boundary to produce persistent strong to severe thunderstorms over Chesterfield Co SC. This rainfall fell over areas where the ground was already saturated from recent heavy rains and caused many small streams to rise out of their banks and flood some roadways and bridges. Hail was also reported with one of the thunderstorms.
