A warm and humid air mass ahead of a low pressure system approaching from the Northern Plains set the stage for the formation of severe thunderstorms over portions of Gogebic County from late evening on the 11th into the early morning of the 12th. The storms caused flash flooding and damaging winds over portions of Gogebic County.

An EF1 tornado touched down near the Wisconsin-Michigan border just southeast of Van Buskirk and caused damage for less than a mile before dissipating. Damage consisted mostly of uprooted or snapped trees.

The NWS storm survey confirmed a low end EF1 tornado about three miles south of Bessemer. Winds from the tornado were estimated around 90 mph. The tornado touched down near the intersection of S. Barber Road and Spruce Road and ended 2.4 miles to the east-northeast, just northeast of the intersection of W. Harding Road and Koski Road. Damage included multiple trees down on a garage on Spruce Street and half a barn destroyed in Bessemer Township on Elder Street. |||The damage path was 200 yards wide or less and occurred just before midnight CDT.

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 Marginal Risk. The outlook in force was issued at 00:50 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.
