Overview

A cold front approached Pennsylvania from the west on Sunday, the 6th of November, and hit very mild air as it entered PA. This abnormally warm air for early November and the strong wind shear in the lowest 10 thousand feet of the atmosphere caused Severe Thunderstorms to develop during the middle of the day.

The storms produced widespread wind damage (mainly trees down and trees on wires) across all the of the northern half of Central PA, but the cells weakened as they moved into the Harrisburg area and the lower Susquehanna valley. A few hail reports were received, especially in eastern PA. This was one of the most widespread and damaging events of the year for Central PA.
