The Hartsville AP warmed to 86 degrees on Tuesday while better coverage of thundershowers developed over the western and Upstate counties. Late night convection above the town of Lyman left 4.81 inches of rain in a CoCoRahs volunteer gage. The same complex of storms filled the gage at Chester with 2.47 inches and 1.89 inches at Gaston Shoals. Thunderstorm cloud tops soared to fifty thousand feet at the noon hour on Wednesday, and moved east. An intense rainfall at the USC Campus produced 0.46 inches in just fifteen minutes. Edgefield measured their heaviest 24-hour rain (2.06 inches) since March 27, 2011. Also on Wednesday, Marion welcomed a rainfall of 2.02 inches. Sunny, cooler weather was observed on Thursday. Cedar Creek reported a sunrise temperature of 48 degrees and most of the state reported afternoon temperatures in the middle to upper 70's. Temperatures eased into the lower 80's on Friday with Barnwell and Pinopolis recording 82 degrees. A partly sunny Saturday helped Florence and Orangeburg reach 81 degrees. Periods of moderate rain to heavy rain were observed on Sunday. Although parts of the state began Sunday with mild conditions, rain cooled air and east winds forced afternoon temperature values to settle in the 60's. For much of Sunday night, areas of heavy rain formed over the South Carolina Mountains and Foothills. The state average temperature for the seven-day period was one degree above normal.
