What happened

The episode as NWS PHI wrote it up.

A southwest flow of air brought another piece of the unseasonably hot air that affected the southern United States over the past couple of months over the area. High temperatures reached record breaking levels across much of the Delmarva Peninsula on the 27th. A cold front moved through the region early in the morning on the 28th and slowly dropped temperatures to seasonal levels. The west to east flow of air over the region the rest of the month also prevented the remnants of Hurricane Georges from affecting the area. High temperatures on the 27th included 95 degrees in Salisbury (Maryland), 93 degrees in Georgetown (Sussex County) and 91 degrees at the New Castle County Airport (a new record), Bridgeville (Sussex County) and Odessa (New Castle County).
