CHARLESTON, S.C. (WCSC) – Much cooler air has taken over to close the weekend behind Saturday’s record-challenging warmth! Behind Saturday night’s front, cold air damming has had quite the influence on our afternoon highs, which only reached the upper 60s and low 70s in most spots. With continued cloud cover and brief, isolated showers nearby, overnight lows will be kept in the 50s to low 60s.
