A low pressure system developed in the lee of the Rocky Mountains on May 9th and moved into the Great Lakes region on May 11th, bringing the chance for some strong to severe thunderstorms for northern Ohio and northwest Pennsylvania. Ahead of this low pressure system, an unseasonably warm air mass settled across the area with high temperature records broken for several sites on May 7-11. As this system moved northeast, a cold front moved across the Midwest, sparking showers and thunderstorms. Several of these thunderstorms reached severe limits and brought damaging winds to some communities in the area.
One of the hardest hit areas was Millcreek Township, Pennsylvania. At about 8pm, a severe thunderstorm moved into western portions of Erie, Pennsylvania. This storm caused significant damage to a mobile home park near the intersection of State Route 5 and Peninsula Drive in Millcreek Township. Many large trees and power lines fell on to trailers. Four mobile homes were destroyed and one received major damage. A fire destroyed one of the impacted trailers, a direct result of the tree and power line damage. In addition, there was a gas leak at the trailer park and evacuations were needed for some trailer homes. Photos from the Millcreek Township Office of Emergency Management of the damage are included below, along with a list of damage reports from several communities in northeast Ohio and northwest Pennsylvania.
