WEEKLY SOUTH CAROLINA WEATHER 2010

September 20, 2010 - September 26, 2010

WEATHER SUMMARY:

Barnwell's Monday morning temperature of 58 degrees soared to 98 degrees by the afternoon. Florence set a date record of 96 degrees. Although the last full day of astronomical summer occurred on Tuesday, Johnston recorded 100 degrees. A weak boundary helped form a handful of localized showers with Jeffries Hydro, near Lake Moultrie, receiving 1.35 inches of rain. Elevated humidity crept back into the state's weather during mid-week. Wednesday's showers were isolated and only brought amounts of less than one-tenth of an inch to a few sites. For the remainder of the state, this was the fourth week of no measurable rain. A frontal boundary moved into South Carolina late Thursday and pushed Friday morning temperatures to more seasonable values. West Pelzer, Calhoun Falls and Ridgeville all cooled to 61 degrees. The heat was back for Saturday with Columbia and Cedar Creek both recording afternoon high temperatures of 96 degrees. On Sunday, showers and thunderstorms began arriving from the south along a pathway left by the nearly stationary boundary. Heavy rains were concentrated across the coastal plains. A thunderstorm over Hampton County produced 1.75-inch diameter hail. At day's end, rain was falling from the mountains to the sea. The state average temperature for the seven-day period was eight degrees above normal.

The highest official temperature reported was 101 degrees at the USC Campus in Columbia on September 20. The lowest official temperature reported was 56 degrees at Chesnee on September 20. The heaviest official 24-hour rain reported was 2.44 inches at the Charleston Airport on September 26. The state average rainfall for the period was 1.3 inches.
