WEEKLY SOUTH CAROLINA WEATHER 2007

August 6 - August 12, 2007

WEATHER SUMMARY:

Record setting heat spread over the state all through the week with the highest temperatures in 24 summers. From Table Rock, at an elevation of 1,020 feet, to Beaufort's near sea level, the mercury rose to 100 degrees or higher. The hot weather peaked on Friday, August 10, with the National Weather Service in Greer setting an all time record high temperature of 105 degrees. Columbia AP tied the site's all time highest of 107 degrees the same day. At 1:45 p.m. Friday, Myrtle Beach AP measured a heat index value of 125 degrees. A southward moving boundary entered the state Friday evening producing violent thunderstorms across the Pee Dee and north coastal counties. A storm survey team from the Wilmington, NC National Weather Service estimated winds in parts of Horry County at 100 mph. Localized pockets of extensive property damage were reported from the straight-line winds. Saturday's isolated thunderstorms upstate dropped heavy rainfall amounts. Sunday was the state's first day in seven days where the afternoon maximum temperature did not reach the century mark. The state average temperature for the period was nine degrees above normal.

The highest official temperature reported was 110 degrees at Johnston on August 10 (this is one degree shy from the South Carolina all time record high temperature of 111 degrees set at Blackville and Calhoun Falls in September of 1925 and Camden in June of 1954).
