Afternoon thunderstorms on Labor Day Monday produced scattered reports of hail and high winds. Early Tuesday morning, Myrtle Beach measured nearly four inches of flooding rains. With the exception of north coastal counties most sites observed dry days and mid-90 degree heat through Thursday. A cold front edged closer late Thursday with a few thundershowers, but the coverage was just not enough to alleviate the statewide dry conditions. Sunny, cooler weather continued through the weekend.
