Widespread severe weather developed across north central and northeast Ohio during the afternoon and evening hours of June 25th.  Ohio was located on the periphery of high pressure over the Southeastern states.  Moisture increased from the southwest around the ridge with dewpoints increasing to near 70 degrees.  An unstable airmass developed during the afternoon as temperatures rose into the mid 80s with mixed layer CAPE values near 2000 j/kg.  Energy moving through the flow aloft helped to initiate convection and provided the shear necessary for damaging winds and large hail.
Numerous tress were brought down by strong winds across northeast Ohio.  Portions of Lorain and Cuyahoga counties were hit particularly bad with downed trees and power outages with several trees falling on homes and garages.  First Energy reported 29,000 customers without power in Lorain and Cuyahoga Counties with at least 10,000 more customers without power in northeast Ohio.  A man was also seriously injured while driving on Interstate 480 when a sign fell off the Valley View bridge and hit his car.  The north side of Canton was also hit particularly hard with numerous reports of downed trees, damage to a grocery store, and a picnic shelter destroyed at Nimishillen Park.
