August 20 - August 26, 2007


100-degree afternoons were reported on Monday through Wednesday. A slight weakening of the high-pressure ridge axis took place during the day on Wednesday. Strong convective thunderstorm cells Wednesday evening caused localized heavy rainfall amounts across the northern Piedmont and eastward into the Pee Dee. Hailstones of 1.75 inches in size were observed in Union County. An increase in clouds on Thursday and Friday helped to lower high temperatures back into the middle 90's. A surface boundary approached from the northwest over the weekend with increased coverage of thundershowers. Saturday's storms at Aiken AP produced a peak wind gust of 58 mph. The nearly stationary front became the focus of periods of passing scattered thundershowers throughout Sunday afternoon and evening. The state average temperature for the period was six degrees above normal.

The highest official temperature reported was 107 degrees at Orangeburg on August 22. The lowest official temperature reported was 63 degrees at Johnston on the morning of August 20.
