Severe Weather Events of June 25 and 26th, 2009

Overview

Two rounds of Severe Thunderstorms hit Central PA this week. The first round was during the late evening hours of the 25th (Thursday). Hot and humid air over the state on Thursday allowed temperatures to reach into the mid and upper 80s, and even the lower 90s in the East. A cold front over the Great Lakes approached the region Thursday evening as energy from an upper disturbance moved across the region. This led to the thunderstorms Thursday Evening, which produced some wind and hail damage over Tioga County (near Wellsboro and Mansfield).

The next round of severe weather kicked off much earlier in the day on Friday (the 26th), as the cold front crossed Lake Erie and into NW PA. These storms had updrafts strong enough to support hail up to Tennis Ball size over Tioga County - again! Locations in Potter and Sullivan Counties also had large hail and a few trees down. Many locations in Tioga County had hail two days in a row, and there were a few reports of trees down, as well. The storms in the NE weakened some as they moved to the south later in the afternoon, but a second area of storms developed during the early evening over the lower Susquehanna Valley - around Harrisburg and York. These evening storms produced wind damage and some hail, as well.
