NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. 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

A storm survey was conducted and an EF1 tornado was confirmed in northeastern Ashland County. The tornado touched down northeast of Sullivan along Black River School Road just to the west of the Medina County line. Two school buildings were damaged by the tornado. One of the schools lost a section of roofing over a gymnasium. Sections of roofing along the remainder of the building were lifted and buckled by tornado winds. Significant amounts of rain water got into the building as a result of this roof damage. Water damage in the school was extensive and the gymnasium floor will need replacement. A modular building used as a classroom also sustained damage. Fences surrounding recreational fields at the school were also damaged. A house across the road from the schools was slightly damaged and a communication tower nearby was toppled. Many trees were downed. The tornado had a damage path around one half mile in length and about 30 yards in width.

The wider storm

A frontal boundary was oriented west to east across central Ohio. The surface frontal boundary, in combination with upper level atmospheric support, allowed for severe thunderstorms to develop across the region. Many of the thunderstorms that day were severe, and even a few tornadoes developed across northern Ohio.

Began near Sullivan (41.0556, -82.1961).
