The path drawn at its surveyed width of 300 yards (0.17 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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 EF-2 tornado with max wind of 115 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 Oliveburg (41.0042, -79.0130).
