Southwesterly flow and moderate instability ahead of an approaching cold front helped to spawn showers and thunderstorms, some of which were severe, across the northern West Virginia pan-handle, and western Pennsylvania on the 7th. With dry air present aloft, several of the storms produced damaging wind gusts that brought down trees and power lines. Front slowed as it crossed into Pennsylvania early on the 8th, and with plenty of moisture, heavy rain became a threat overnight. Some flooding was reported in Allegheny county in Shaler and McCandless Townships.
