WEEKLY SOUTH CAROLINA WEATHER 2015

WEATHER SUMMARY:

Heavy rains fell within the coastal zones on Monday morning, the last day of August. The Charleston AP measured a calendar-day total of 6.43 inches and part of a twenty-four-hour total of 7.24 inches. Preliminary records indicate the 7.24 inches amount being the fourth greatest twenty-four-hour total since recordkeeping began at the Charleston AP in 1938. The Naval Weapons Station near Goose Creek measured 4.05 inches. The August 2015 state rainfall ranged from a high of 12.01 inches at the Georgetown AP to a low of 1.49 inches at Fort Mill. Additional rainfall measurements taken on Tuesday morning included Jamestown's 4.25 inches and Georgetown's airport total of 4.00 inches. A sunny Sandhill in Richland County recorded a September 1 high temperature of 95 degrees. Summertime-like heat was observed on Wednesday with Bennettsville and Hartsville also reaching 95 degrees. The leftover circulation and showers of a once Tropical Storm Erika made their way northward into the southeastern-most beaches on Wednesday afternoon. Rainfall amounts taken by CoCoRaHS observers included 2.25 inches at Yemassee and 1.58 inches at Daufuskie Island. Greenville, Clinton and Lugoff all recorded a Thursday high temperature of 94 degrees. Friday's hot weather and the approach of a lifting layer from the north caused strong storms across the state. At 3:40 p.m., half dollar-sized hail fell near Jalapa in Newberry County. Straight line winds, estimated at 70 mph by the Beaufort County Emergency Management storm survey team, roared along the Seabrook Highway at 4:10 p.m. taking down at least ten large oaks.
