Both airports in Columbia reached 98 degrees. The "dart board" distribution of showers brought the Greenville-Spartanburg AP 0.75 inches and its heaviest rain since May 18. Sub-tropical conditions on Tuesday made for a hot and humid late morning into evening day. A localized thundershower over the USGS gage on the Broad River east of Gaffney produced 1.44 inches of rain in 15 minutes and a 2.11-inch total. A CoCoRaHS volunteer observer in York measured 2.47 inches. Isolated cells left 2.04 inches of rain at Little Mountain and 0.47 inches at Edgefield. Bamberg and Bennettsville reported a Tuesday high temperature of 97 degrees. Upper air soundings over Charleston indicated a freezing level of 17,242 feet. All day sun on Wednesday sent the mercury to 96 degrees at the Anderson AP, McCormick and Jamestown. Disorganized storms on Wednesday brought 2.00 inches of rain to Keowee Dam, 1.38 inches to Aiken and 0.92 inches to Clinton. Little change was observed on Thursday. The Orangeburg and Walterboro airports both recorded 99 degrees. Scattered showers, preceding a frontal boundary, formed over Chesterfield County and eastward. McBee was underneath a heavy rain of 2.28 inches, of which 0.97 inches fell in 15 minutes. Dillon measured 1.50 inches, and 1.24 inches fell at Galivant's Ferry. On Friday, slightly drier air on northeast winds moved into the Pee Dee's counties bordering North Carolina. The N Myrtle Beach AP reported a Friday high temperature of 89 degrees. Hilton Head's clouds and showers only allowed for a Friday maximum temperature of 82 degrees. For Shaw AFB and Bishopville, Friday was another day at 96 degrees. July's thirty-one-day rainfall ranged from a high of 7.72 inches at Charleston AP to a low of 1.10 inches at Travelers Rest. Friday's change to a drier, milder air mass expanded into the Upstate and Midlands for Saturday. Rock Hill and Sandy Springs started the day at 66 degrees. Any showers that fell were localized and along the southernmost counties. Edisto Island measured one of the heaviest rains with 1.92 inches. Chester, Longtown and Holly Hill all shared a Saturday afternoon high temperature at a seasonal 93 degrees. The Columbia Metro AP and Shaw AFB 4:00 p.m. observations of 96 degrees was somewhat offset by a relative humidity value of 29 percent.

Cades reported 2.34 inches of rain. The Beaufort Marine Corps Air Station measured a Sunday calendar-day total of 2.29 inches and Hilton Head received 0.99 inches in 20 minutes. At 5:00 p.m., instruments at Springmaid Pier noted a "season high" surf water temperature of 87.6 degrees. Union and Hartsville recorded a Sunday high temperature of 97 degrees.
