A deep surface flow of tropical moisture set the stage for rains on Monday, Tuesday and Wednesday. Heavy rainfall rates on Tuesday produced flash flooding across the upstate and central coastal counties. A tornado was reported on Wednesday evening in Darlington County causing damage to several mobile homes. While the wet weather helped improve dry conditions over western sites, it slowed recovery efforts over the flooded Waccamaw River basin. A cold front cleared the state on Thursday bringing in much cooler temperatures and sunny skies. Friday morning minimum temperature readings fell into the upper 30's and 40's. A slow warming trend under mostly sunny skies was observed over the weekend with Sunday afternoon temperatures peaking in the mid-80's. Statewide temperatures for the period averaged near normal.
