Thanks to a stalled frontal boundary positioned across South Carolina cloudy, cool, wet weather persisted through the work week. On Tuesday, daytime high temperatures only managed to climb into the upper 60's and low 70's. Several sites from the Piedmont eastward to the coast received between two and four inches of rain. Over the weekend breaks in the cloudiness allowed for warmer afternoons and widely scattered late afternoon and evening thunderstorms. Statewide temperatures for the period averaged six degrees below normal.
