More summer heat, high humidity and scattered storms were observed through most of the work week. The Georgetown AP recorded 96 degrees on Monday. Thundershowers over the Upstate left 2.21 inches of rain at Jocassee and 1.54 inches at Fountain Inn. It was 95 degrees at Darlington on Tuesday afternoon. A cluster of storms over York and Lancaster counties brought Lake Wylie 1.69 inches of rain and Catawba 1.34 inches. More cloudiness on Wednesday limited the afternoon convection. Scattered thundershowers on Thursday night developed over the north Midlands leaving 2.34 inches of rain at Longtown. A CoCoRaHS volunteer in Camden measured 1.91 inches. Hardeeville and Pinopolis warmed to 93 degrees on Friday under partly sunny skies. A long-awaited change to drier, cooler air approached the state on Saturday, but not before Florence and Beaufort noted 92 degrees. The fall-like boundary produced widespread thunderstorms as it collided with the outgoing tropical air.
