What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

NWS Storm Survey confirms an EF01 tornado with maximum wind of 95 mph.

The wider storm

Aided by a cold front and a shortwave, a strong line of thunderstorms developed in central Ohio and quickly progressed east across western Pennsylvania and northern West Virginia. A moisture rich environment with mid to upper 60s dew points and mid 70s temperatures supported a favorable setup with MLCAPE values around 1000 J/kg and strong effective shear of 40-50 knots. Widespread swaths of wind damage were noted with 60-80 mph wind, and plenty of low level shear also supported embedded mesovortices and transient tornadoes within the line of thunderstorms.

Began near Park View (40.9897, -80.1391).
