At 3:00 p.m. on Friday, both Florence and Charleston airports had a heat index value of 110 degrees. Strong thunderstorms formed in advance of an early fall-like cold front that afternoon and evening. Several eastern and southern counties had damaging high winds and minor street flooding. Much cooler and drier air spread over the state Saturday. Sunday's weather may have been the most pleasant so far this summer. Low temperatures fell into the 50's across high elevation and normally cold, sheltered areas. Sunny, blue skies, mild 80 degree warmth and brisk northeast winds resulted in a welcomed break from the seemingly, never- ending heat. Temperatures for the period averaged two degrees above normal.
