SOUTH CAROLINA WEATHER AND CLIMATE
April 28- May 4, 1997
WEATHER SUMMARY
Strong thunderstorms over mostly northwest counties began the week
and produced multiple reports of hail with some as large as golf balls.
Rainfall event totals were greatest along coastal counties with Edisto
Island reporting an event total of 5.98". On Wednesday morning widespread
fog was common across the state with visibilities at some sites reduced to
1/16th of a mile. Sunny, warm weather returned on Thursday and Friday with
afternoon temperatures in the 80's. On Saturday, May 3, an active cold front
moved through South Carolina. Moist, southerly winds, well ahead of the

afternoon. During the late afternoon hours on Saturday, severe storms formed
over the eastern counties. Hail and high winds caused light property damage,
downed trees, and power disruptions. Hail was observed as large as 1.75" in
Dorchester County. The week ended on a sunny, breezy day and afternoon
temperatures running around 10 degrees below normal. Statewide temperatures
for the period averaged 4 degrees below normal across central midlands and
westward to normal along the coastal plain.
