WEEKLY SOUTH CAROLINA WEATHER 2015

July 6 - July 12, 2015

WEATHER SUMMARY:

Winnsboro, Aiken and Dillon all reported a mostly sunny Monday and a high temperature of 91 degrees. Individual showers brought McBee 0.38 inches and 0.23 inches to Georgetown AP. Seabreeze forcing on Tuesday helped in the formation of thundershowers along the coastal plain. The Naval Weapons Station near Goose Creek measured 1.29 inches, 0.96 inches fell in Holly Hill and 0.71 inches was noted at Bennett's Point. Drying heat on Wednesday pushed the thermometer to 96 degrees at Columbia Metro AP and Clarks Hill. Scattered afternoon and evening storms drifted from the Foothills through the upper Piedmont eastward along the border with North Carolina. Gaston Shoals reported rains of 0.74 and 0.58 inches fell at the Rock Hill AP. Dillon received a welcomed 1.19 inches. Thursday afternoon could only be described as very hot for any hours spent outside. At 3:00 p.m., Chester, Lancaster and Hartsville all reported 99 degrees. The Springmaid Pier surf-zone 2:00 p.m. observation of 82 degrees and south winds of 15 mph was one of the few locations offering relief from the heat. Subsiding air on Friday moved the mercury to the century mark or higher from the Upstate to the coast. The Greenville-Spartanburg AP and Jamestown each recorded 100 degrees. A sampling of more triple-digit heat included Bishopville and Cades (102 degrees), Union and Lugoff (101 degrees), and Chester and Sumter's Shaw AFB (100 degrees). The Florence Regional AP 6:00 p.m. observation indicated 102 degrees with 17 percent relative humidity. The Sandhill Experiment Station measured a 24-hour open pan evaporation (water loss) of 0.49 inches. Saturday's discomfort from a bight summer sun and high humidity was especially pronounced at the coast. The 2:00 p.m. shade temperature at Myrtle Beach and Mt. Pleasant was 99 degrees. An isolated thunderstorm at Kingstree's Williamsburg Regional AP caused winds of 41 mph and a localized downpour left 1.78 inches of rain in the N Inlet, Georgetown County gage. At a refreshing elevation of 3525 feet, Sassafras Mountain's Saturday high temperature only made it to 82 degrees. Northwesterly winds aloft on Sunday tempered the excess surface heating with increased cloudiness and passing showers. Lake City received one-half inch of rain. The Saturday high temperature of 99 degrees at the Marion County AP eased back to a more sensible 90 degrees for Sunday. The state average temperature for the seven-day period was four degrees above the long-term average.

The highest official temperature reported was 103 degrees at Sandhill and Lake City on July 10. The lowest official temperature reported was 58 degrees at Jocassee 8WNW (Walhalla Fish Hatchery) on July 6.
