WEATHER SUMMARY
With the official start of Winter over two weeks away one would have never guessed a winter storm would affect South Carolina so early in the season. Monday and Tuesday preceded the storm with sunny cold weather before cloudiness spread into the western counties early Wednesday. With temperatures hovering around freezing, precipitation started falling into a shallow layer of thirty degree air, setting the stage for icing that stretched from the mountains eastward to North Charleston. By late in the day on Wednesday, freezing rain had accumulated on trees, power lines, and elevated surfaces. Hardest hit were counties across the northern midlands and upstate. Ice up to three quarters of an inch felled limbs, caused loss of electricity and was the blame for vehicle accidents. Nearly one half million customers were reported to have experienced power failure. Clouds were slow to clear on Thursday while afternoon temperatures remained in the 40's. High pressure helped clear conditions over the weekend with mostly sunny weather and sub-freezing mornings. The average statewide temperature for the period was eight degrees below normal.
