Hail Storms of May 27th, 2007

Overview

Scattered showers and thunderstorms formed in the very warm and humid air over the mountains of Central PA during the midday of Sunday the 29th, and another line of storms formed over Central OH. The storms over OH died through the afternoon as the moved into an unfavorable environment over Western PA, but the cells over Central PA moved into the Eastern half of the state, and began to produce copious hail.

Additional storms that fired up over Central VA moved to the left of the mean flow -- moving almost due north, and into Southeastern PA, late in the day. These storms proved to be the most dangerous, as they made very large hail, with many reports of Nickel-sized (0.88 inch) to Quarter-sized (1.00 inch) hail.
