The atmosphere was very unstable yesterday and produced a number of vigorous thunderstorms producing high winds, hail, and perhaps a few brief tornados. The featured map is of a very prolific hailer near Waterloo. Numerous reports of golfball and larger size hail were made with this storm. A report of a 4.5 inch hail stone was received from near Janesville!
