September 15 - September 21, 2014


Cheraw, Sandhill, Johnston and Lake City started the week with a Monday low temperature of 65 degrees. Cloudy skies and passing showers were observed over the state. A few of the heavier rainfalls included 1.60 inches at Summerville and 1.57 inches at Blackville. Stormy weather on Tuesday produced one-inch hailstones over parts of Greenville County and a 66-mph wind gust near Tigerville. Barnwell and Beaufort warmed to 91 degrees. More one-inch hail fell during a late afternoon thunderstorm at Orangeburg. Allendale was the state's warm location on Wednesday with 89 degrees. Thursday's daybreak was obscured by areas of dense fog. Newberry, Winnsboro and Sumter all reported visibilities of less than one-quarter mile. An ill-defined boundary, best-placed through central South Carolina, separated the northern counties' cooler conditions from the seasonal warmth over the southern counties. At 2:00 p.m., Columbia, Darlington and Myrtle Beach each noted partly sunny skies and 81 degrees. Only an hour earlier, Charleston AP had met its maximum value for the day at 89 degrees. During the pre-dawn hours of Friday, a cluster of heavy thundershowers moved south through Lancaster County with flash flooding. The CoCoRaHS volunteer in Lancaster County measured 5.76 inches. Torrential rains continued, moving south through Kershaw and Richland counties. The Columbia Hamilton-Owens AP measured 1.59 inches of rain in twenty minutes. Portions of Interstate 20 and 26 were temporarily flooded due to slow drainage and roadbed ponding. Localized downpours extended their reach to the coast. McClellanville reported rains totaling 2.20 inches and Edisto Island received 2.00 inches. On Saturday, much of the coastal plain was cool and cloudy. The Charleston airport's afternoon high temperature of just 75 degrees was their "lowest maximum" since May 2. Barnwell's Sunday sunrise temperature of 57 degrees moved to a summer season-ending 91 degrees. The state average temperature for the seven-day period was one degree above the long-term average.

The highest official temperature reported was 92 degrees at Summerville on September 15. The lowest official temperature reported was 54 degrees at Hunts Bridge and Spartanburg on September 21. The heaviest official 24-hour rainfall reported was 2.65 inches at Chesterfield ending at 7:00 a.m. on September 17. The state average rainfall for the seven-day period was 1.1 inches.
