WEEKLY SOUTH CAROLINA WEATHER 2011

September 12, 2011 - September 18, 2011

WEATHER SUMMARY:

A few light showers formed along the southern coastal counties before sunrise on Monday morning. The Beaufort Marine Corps Air Station measured 0.06 inches of rain. At 4:00 p.m. the Columbia Metro AP reported 92 degrees and a relative humidity value of 22 percent. Cades, Bamberg, McCormick and Barnwell reached a high temperature of 94 degrees. On Tuesday morning, the dry nature of the air helped cool the temperature at Johnston to 57 degrees. During the late afternoon hours, Johnston's high temperature soared back to 95 degrees. Scattered showers formed along the coastal plain and left Cades with 0.74 inches of rain and Givhans with 0.62 inches. McCormick reported a hot and dry Wednesday with a maximum temperature of 96 degrees. Thursday began with clouds entering the South Carolina mountains and another round of hot weather for everyone else. Allendale topped out at 96 degrees. In the darkness of Friday morning, Springmaid Pier recorded wind gusts of 44 mph. At 5:39 a.m., Shaw AFB in Sumter reported 63 degrees, northeast winds of 22 mph, gusting to 31 mph. A cluster of pre-dawn thunderstorms produced intense rainfalls of 1.12 inches at Charleston City and 0.90 inches at Ft. Moultrie. Friday's combination of a frontal boundary with its modified Canadian air and subsequent cloud cover made for good riddance of the summer-long heat. Chester and Bennettsville recorded Friday high temperatures of just 60 degrees. Most of the state observed cloudy, cool conditions and occasional light rain, drizzle or mist into Sunday. Edisto Beach and Bennett's Point recorded the state's Sunday high temperature at 77 degrees. The state average temperature for the seven-day period was one degree below normal.

The highest official temperature reported was 97 degrees at Columbia Metro AP and Barnwell on September 15. The lowest official temperature reported was 50 degrees at Long Creek and Pelion on September 17. The heaviest official 24-hour rainfall reported was 1.42 inches at Mullins ending at 7:00 a.m. on September 16. The state average rainfall for the period was 0.1 inches.
