A warm front worked north towards Lower Michigan during the evening hours of the 5th. Storms were initially slow to organize, but quickly intensified and became super-cellular. One of these storms tracked into Fulton County and quickly spawned a tornado north of Liberty Center. The tornado remained on the ground for roughly 7 miles producing damage along its track before dissipating near the Fulton/Lucas county line.

The tornado touched down along Highway 109 just north of County Road A and moved northeast, impacting several homes, trees and power lines. Several homes were severely damaged or destroyed (DI:FR12 DOD: 8). However, improper anchoring of some of the homes resulted in a failure on all walls, resulting in their destruction. Several trees were uprooted or damaged, including through the Maumee State Forest. The tornado ended near the Fulton/Lucas county line. The maximum width of the tornado was around 700 yards with maximum wind speeds estimated around 130 mph. Damage is estimated at $500,000.

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 Slight Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 01:06 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.
