A stationary frontal system stretched across the lower Great Lakes on the morning of Saturday, June 5th. This resulted in a very warm and humid airmass over northern Ohio. Outflow boundaries from earlier storms interacted with the stationary front to initiate thunderstorm development during the afternoon hours across inland northern Ohio. One of the stronger thunderstorms produced tornadoes in Richland and Holmes Counties. There were also a few reports of straight line thunderstorm wind damage. A rapidly deepening area of low pressure moved quickly east across southern lower Michigan during the evening hours. This low eventually moved across Lake Erie during the early morning hours of the 6th. Showers and thunderstorms developed across northern Indiana during the evening hours. These storms intensified and moved east along the stationary front and into Northwest Ohio. A devastating EF4 tornado developed over Wood County a little before midnight. This tornado moved into Ottawa County before dissipating. Seven people were killed and dozens of homes destroyed by the tornado. A weaker tornado also moved across portions of Lucas County. A third round of storms developed during the early morning hours of the 6th ahead of a cold front trailing the low. These storms moved across northern Ohio and produced pockets of damage. An EF1 tornado occurred in Ashtabula County around daybreak. A total of five tornadoes occurred in northern Ohio on June 5th and 6th. These tornadoes killed seven people, injured dozens and destroyed or damaged over a 100 homes. A school and a public administration building were also leveled. Damage estimates easily topped $100 million.

An EF0 tornado touched down in rural Richland County about two miles north northwest of Lucas. The initial touchdown occurred near the intersection of Crimson and Mount Zion Roads. The tornado then continued southeast for around four tenths of a mile before dissipating. The damage path suggests that the tornado may not have been in constant contact with the ground. The damage path was no more than 20 yards in width. A barn was leveled by the tornado and two other buildings were damaged. Four cattle were injured by flying debris. Debris from the destroyed barn was found about three miles away from the location of the touchdown.

5 minutes of warning. NWS CLE issued a tornado warning for this county at 17:41 UTC, 5 minutes before the tornado touched down, in force until 18:30 UTC.

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 Moderate Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:29 UTC.

42 more were confirmed in the United States that day.

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.
