The path drawn at its surveyed width of 60 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

A weak tornado touched down southeast of Morgantown in the 2800

block of Kingwood Pike. There was roof damage to four structures.

One house lost over half its roof, while the others had less than

20 percent of their roofs affected. A support beam to a covered

porch was blown out at a residence. Meanwhile a utility pole was

ripped loose and landed on the side of a house. There were around

10 trees that were either uprooted or snapped. The estimated maximum wind speed was 65-70 MPH.

The wider storm

In the wake of morning rain, cloud breaks developed from Virginia into south central Pennsylvania during the afternoon. CAPE values climbed to near 1000 J/kg, despite poor mid-level lapse rates. Disturbances rotating around the southeastern periphery of a Great Lakes/upper Ohio Valley trough helped to increase low level flow and shear. This proved sufficient to allow afternoon storms to rotate.

One storm produced a weak EF0 tornado in Monongalia county off Kingwood Road. There were several trees uprooted and snapped. Five homes lost parts of their roof.

Multiple rounds of thunderstorms also produced flash flooding in Tucker County during the evening hours, mainly in the vicinity of Route 38 to the northwest of Parsons.

Began near Burns Chapel (39.5430, -79.8750).
