Showers and thunderstorms developed across upstate New York and northeast Pennsylvania ahead of a slow moving cold front that extended from southern Ontario to lower Michigan. The airmass ahead of this front was warm and unstable, and with the aid of an upper level disturbance, severe thunderstorms developed over the area. Some of the storms produced very large hail and damaging winds.
