A very strong area of low pressure moved northeast across the Central Great Lakes on September 10th. A warm front stretching southeast from this low lifted across northern Ohio causing showers and thunderstorms to develop during the afternoon. At least four weak tornadoes touched down in Summit and Portage Counties. Several funnel clouds were also reported in Wayne County.

The same thunderstorm that produced a weak tornado in Stow also produced a tornado a few miles away near the small village of Sugar Bush Knolls in western Portage County. This EF0 tornado initially touched down near the intersection of Spell Road and Judson Road. The tornado continued northeast for nearly a mile and crossed the Raccoon Hill Golf Club. The tornado eventually lifted after crossing Hudson Road. Many trees were downed along the damage patch which was up to 50 yards in width.

A very weak EF0 tornado touched down near Streetsboro. The touch down occurred just south of Lake Rockwell Road to the west of State Route 14. The tornado was on the ground for about a tenth of a mile and lifted before reaching State Route 14. The tornado downed one tree and tore the branches off a couple other trees. The damage path was no more than 20 yards in width.

An EF0 tornado touched down northwest of Hiram near Allyn Road. The tornado continued northeast on the ground for about three quarters of a mile to near Winchell Road and then lifted. A couple of homes along Winchell Road sustained minor damage. A few trees were uprooted and many tree branches broken along the damage patch which was no more than 50 yards in width.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 19:36 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
