Pulse Storms and Record Heat of July 27th, 2007

Overview

Thunderstorms fired up in the afternoon of Wednesday the 27th, as near-record heat over Central PA combined with ample moisture to initiate and continue the thunderstorms.

None of the storms were particilarly long-lived, as they were moving only slowly and would stifle themselves as they rained onto the hot spot that initially help them each fire up.

A Record High of 97 degrees occurred at Williamsport, PA (KIPT) Wednesday afternoon. This high temperature broke the previous record for the 27th of June, which was 95 degrees, from 1963.
