An unseasonably cold boundary dropped south from Canada early in the week. Stormy weather was reported on Tuesday and into Wednesday morning. Large hail fell in Anderson and Charleston Counties. Clouds and drizzle, circulating around low pressure, passed eastward through South Carolina on Thursday. Afternoon high temperatures felt more like mid-winter and remained in the 40's. Increasing northeast winds of between 30 and 40 mph forced blowing sand and large breakers along the beaches. Clearing skies were observed Saturday evening. The cold and dry air mass allowed the mercury on Sunday morning to fall below freezing across the higher elevations and produced frost at the usual cold sites. For the period, the state average temperature was five degrees below normal.
The highest official temperature reported was 84 degrees at Jamestown on April 11. The lowest official temperature reported was 29 degrees at Cedar Creek on the morning of April 17.
