The wider storm

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.
