A low-amplitude mid/upper level trough coupled with moderate instability allowed for thunderstorm development over the higher terrain of central PA during the late morning. Storms encountered a more favorable convective environment as they moved east during the afternoon, becoming more organized near edge of stronger northwesterly flow aloft and deep-layer shear. The storms that intensified to severe levels produced sporadic wind damage.
