SOUTH CAROLINA WEATHER AND CLIMATE
April 21-27, 1997
WEATHER SUMMARY
Sunny, warm weather began the week as afternoon temperatures climbed
into the 80's. Thunderstorms were reported late Monday afternoon across
the upstate with isolated hail episodes. On Tuesday afternoon, severe
weather associated with a highly unstable air mass produced widespread
thunderstorms which included hail up to golf ball size in Fairfield, Laurens,
Aiken and Horry counties. Many other counties also reported hail ranging
in size from one quarter to one and a half inches. Several growers reported
scattered damage. High winds exceeding 58 mph caused isolated structural
damage, felled trees and disrupted utilities. Rainfall amounts from
Tuesday's storms were heaviest over the western counties. A nearly
stationary boundary positioned across the state during mid-week provided
cloudiness and light showers. As low pressure approached over the weekend
along the western end of the front, more rainshowers, some heavy, occurred
on both Saturday and Sunday. Statewide temperatures for the period averaged
4 degrees below normal across the western half of the state to 2 degrees
below normal along the coastal plain.
