A few rounds of thunderstorms on July 24th and 25th preceded a cold frontal passage.  High levels of instability, ample shear, and pre-frontal disturbances provided thunderstorm clusters producing widespread damaging wind gusts.  Many instances of tree and power line damage were noted, along with isolated instances of structural damage.  One of those instances of structural damage, a tree falling on to two trailers in Venango County, unfortunately led to the death of a 28 year old woman.  Flash flooding of urbanized areas of Allegheny County also occurred.
