WEEKLY SOUTH CAROLINA WEATHER 2009

May 11, 2009 - May 17, 2009

WEATHER SUMMARY:

The week began with much cooler temperatures on the heels of building high pressure. Table Rock reported a high temperature on Monday of only 60 degrees. On Tuesday morning, McClellanville recorded a minimum temperature of 53 degrees. Deep-layer surface winds shifted to a more onshore direction Wednesday and by Thursday the airmass had become quite tropical in nature. Slow moving thunderstorms on Thursday produced localized flooding near the Charleston Airport as 0.67 inches of rain fell in fourteen minutes. Relative humidity values of 100 percent were observed at many locations Friday morning. Seabreeze boundaries help contribute to widely scattered showers for much of eastern South Carolina into the weekend. For sites receiving the most sunshine hours, afternoon high temperatures on both Friday and Saturday climbed into the mid-80's. A frontal boundary approached from the west Sunday, bringing evening rains and falling temperatures. The state average temperature for the period was two degrees below normal.

The highest official temperature reported was 89 degrees at Manning on May 16. The lowest official temperature reported was 43 degrees at Hunts Bridge on May 12. The heaviest 24-hour rainfall reported was 2.36 inches at the Bishopville USGS gage ending at 7:00 a.m. on May 17. The state average rainfall for the period was 1.9 inches.
