August 3, 2009 - August 9, 2009


The state's highest elevations reported minimum temperatures in the lower 60's all week. Monday's interaction between the sea-breeze boundary and inland surface heating produced widely scattered thunderstorms over the counties bordering the coast. Anderson, Greenwood and Greer all recorded 96 degrees on Monday afternoon. Although Hunts Bridge received 1.21 inches of rain Tuesday it was one of the few sites in the Upstate reporting rainfall for the period. Weather observation instruments within the Savannah River Plant complex recorded a 73 mph wind gust during a storm Wednesday afternoon at around 5:00 p.m. Clarks Hill measured 1.60 inches of rain from Wednesday's event and nearby Johnston sweltered under a 98 degree high temperature. During the 24-hours ending at 7:00 a.m. Thursday morning, the Sandhill monitoring site reported an open pan evaporation water loss of 0.42 inches. Thursday's isolated downpour at McClellanville left 1.69 inches of rain in their gage. Lower humidity values accompanied rising air pressure over the weekend but did little to suppress the drying heat. Locations away from the immediate beaches recorded high temperatures on Sunday in the middle and upper 90's. The state average temperature for the period was two degrees above normal.

The highest official temperature reported was 100 degrees at Lake Wateree on August 9. The lowest official temperature reported was 58 degrees at Walhalla Hatchery (Jocassee) on August 6. The heaviest 24-hour rainfall reported was 1.85 inches at Charleston AP on August 4. The state average rainfall for the period was 0.3 inches.
