A severe thunderstorm produced a downburst just north of Liverpool on the morning of July 9, with winds estimated between 85 and 95 mph.

The path length of the downburst was less than a quarter of a mile, with a maximum path width of approximately 125 yards.

Wider weather episode

Showers and thunderstorms developed in a warm and humid airmass over central Pennsylvania with moderate CAPE and very little CIN ahead of an approaching cold front. A few of the storms produced sporadic wind damage, and the widespread nature of this activity allowed the event to evolve into a flash flooding threat as well.
