A semi-organized band of convection extending southward from the Buffalo, NY vicinity to near Pittsburgh, PA and Charleston, WV moved eastward during the late afternoon and evening hours. The band evolved into a well-defined linear feature with enhanced bowing segments, increasing damaging wind potential as it moved into a moderately unstable air mass located across central and eastern PA. Widespread damaging straight-line winds with embedded microburst damage accompanied the line as it crossed the Mid-State, knocking down numerous trees and utility wires. The damaging winds also caused localized structural damage and thousands of power outages. A few discrete cells ahead of and embedded in the main convective line tapped into strong low-level shear/helicity, which proved to be a favorable environment for tornadogenesis. Following official NWS storm surveys, an EF2 tornado was confirmed near Dushore in Sullivan County along with a 90-100mph microburst in Perry County.
