Remnants of a mesoscale convective system created a few supercells in eastern Ohio that advanced into northern West Virginia/western Pennsylvania. Two tornadoes spun up from a single supercell. Despite meager instability, deep-layer wind shear was favorable at near 40 knots, and the storm tracked in a favorable direction to ingest rotating updrafts.

between 735 PM and 741 PM. As the tornado crossed Morris Run Rd,
it caused a barn to collapse, with debris blown to the property
across the road. The tornado continued to uproot trees as it
traveled southeast, and it also removed siding from a house.
