EF2 tornado in Erie County, Pennsylvania

This tornado had peak intensity of EF2, estimated peak winds of 115-mph, a maximum damage path width of 150 yards, and moved generally northeastward during its lifespan. The tornado began just northwest of the intersection of Plum Road and Page Road, and generated suction marks in a field before toppling a large tree and destroying a barn near Knoyle Rd. The tornado crossed Knoyle Road and struck a second barn directly, which contained several vehicles and trailers. The barn was destroyed, leaving the cars heavily damaged and a trailer overturned. Debris from the structure settled into a nearby field and adjacent woods. Two horses and several cows were killed as a result of the tornado. A nearby home sustained moderate damage, including ripped siding along the western side, broken windows, and a blown-out side door. The tornado continued across an open field before entering a wooded

area, where it damaged several trees. The tornado dissipated soon thereafter.

At the surface, a cold front extended southwestward across eastern Lake Erie, northeast OH, and southwest OH, during the early afternoon of the 9th and drifted eastward to near the corner of northeast OH along the border of northwest PA by mid-evening. Ahead of the cold front, multiple clusters of multicell thunderstorms, including bow echoes, persisted generally east-northeastward. These storms generated very isolated straight-line wind damage and two mesovortex-related tornadoes; a weak tornado in Crawford County and a strong tornado in Erie County. The storms traversed an ambient environment comprised of weak MUCAPE, moderate to strong effective bulk shear, favorable mixed layer LCL's less than 1500 meters AGL, and marginally-favorable surface-based ESRH near 100 to 150 meters squared per second squared.
