EF-2 tornado confirmed in eastern Erie County, Pennsylvania on June 9

The tornado touched down northwest of the intersection of Plum Road and Page Road, where visible ground swirls were observed. Moving northeast, it toppled a large tree and destroyed a barn near Knoyle Road.

It continued across Knoyle Road, directly striking a second barn that housed multiple vehicles and trailers. This structure was destroyed, with vehicles heavily damaged and a trailer overturned. Debris from the barn was scattered into a nearby field and adjacent woods.

Several animals, including two horses and multiple cows, were killed in the event. A nearby house sustained moderate structural damage, including torn siding on the west side, broken windows, and a blown-out side door. The tornado then moved through open terrain, damaging several trees in a wooded area before dissipating at approximately 17:52 LT.

This tornado occurred as part of a regional severe weather outbreak associated with a potent shortwave trough moving northeast across the Ohio Valley. The synoptic setup featured high vertical wind shear values between 40–50 knots and modest instability with MLCAPE values ranging from 500 to 1 000 J/kg, characteristic of a high-shear, low-CAPE (HSLC) environment.

Two additional tornadoes were confirmed during the same event. One, an EF-1 tornado, touched down near Lake Buckhorn in Holmes County, Ohio, between 17:28 and 17:31 LT. It produced peak winds of 170 km/h (105 mph), damaged multiple trees, lifted a pontoon boat and dock, and caused structural damage to several homes. No injuries were reported.

Another tornado, rated EF-0, moved ashore from Lake Canadohta as a waterspout in Crawford County, Pennsylvania, at approximately 15:45 LT. It traveled 0.7 km (0.45 miles) with peak winds of 113 km/h (70 mph), damaging tree limbs, rooftops, and power infrastructure before lifting at 15:47 LT. There were no casualties associated with this tornado either.

The EF-2 tornado on June 9 was the 17^th tornado confirmed in Pennsylvania this year and the first classified as significant, defined as EF-2 or stronger, according to the Enhanced Fujita scale.
