A warm front lifted north across the area during the afternoon leaving a warm and unstable airmass in place. An area of thunderstorms moved across northern Ohio during the afternoon and evening producing a few areas of severe weather. The worst of the damage was an EF1 tornado in Brunswick in Medina County. The tornado was on the ground for 1.7 miles, touching down near Diana Drive and Maria Drive, then tracking northeast and lifting near Clover Road and Carpenter Road. Approximately 45 buildings were damaged, with two homes sustaining major damage. Maximum wind speeds were estimated around 110 mph with a maximum path length of 120 yards. Strong winds were reported just east/southeast of Toledo with two semi-trucks blown over in northern Wood County and approximately 10,000 power outages in Lucas County.

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 19:45 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.
