Showers and Thunderstorms from the Great Lakes into the Southern Plains

Overview

A line of storms moved into Western Pennsylvania during the afternoon of April 3rd, 2006, and produced large amounts of small hail. A few reports of wind damage in large/damaging hail were received from Warren County (Northwestern PA), but all the rest of the hail was smaller than pennies - which is the threshold for severe/damaging hail.

The unusual thing about these storms is that they made copious amounts of small hail - as it covered the ground in many places in the Laurel Highlands and Allegheny Plateau.
