The path drawn at its surveyed width of 400 yards (0.23 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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 a tornado near Alliance Furnace.

The wider storm

Ahead of an approaching cold front and aided by leading shortwave-induced ascent, a cluster of thunderstorms tracked across southeastern Ohio and western Pennsylvania producing wind damage, several tornadoes, and a few instances of large hail. Moist southerly flow pulled upper 50s to low 60s dew points with surface temperatures in the mid 70s allowing for sufficient destabilization up to 1500 J/kg of MLCAPE, 35-40 knots of effective shear, and 50-150 m2/s2 of 0-1 km SRH to support an all hazards threat.

Began near Jacobs Creek (40.1101, -79.7424).
