The path drawn at its surveyed width of 20 yards (0.01 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

An EF0 tornado briefly touched down in extreme eastern Crawford County. The touchdown occurred along Mageetown Road in rural Rome Township. The tornado was on the ground for around a half mile before lifting. Two homes along the damage path sustained roof damage. A few trees were also downed. The damage path appeared to be no wider than 20 yards.

The wider storm

A stationary front remained stretched across the Upper Ohio Valley during the early morning hours of June 6th. This front kept a very warm and humid airmass over northwestern Pennsylvania. A rapidly deepening area of low pressure moved quickly east across southern lower Michigan during the evening hours of June 5th. This low eventually moved across Lake Erie during the early morning hours of the 6th. Showers and thunderstorms developed along the stationary front stretching east from the low. These storms eventually moved into northwestern Pennsylvania during the early morning hours of June 6th. One of the stronger thunderstorms produced a downburst which overturned a camper trailer and killed a man. The same thunderstorm later produced a tornado in western Erie County. A second line of showers and storms affected Erie and Crawford Counties around daybreak on the 6th. These storms developed ahead of a cold front trailing the low. A tornado occurred in Crawford County just after daybreak.

Began near Rometown (41.7191, -79.6311).
