Severe thunderstorms developed across western Wisconsin and moved eastward across southern Wisconsin through the afternoon and evening hours on June 22nd due to passing low pressure and its approaching cold front. There were supercell thunderstorms along with bowing segments along this line which lead to multiple areas of damage. Two strong tornadoes occurred, which were rated EF-2 near Argyle and through the south side of Janesville. Many reports of flash flooding were received due to torrential rainfall and slow storm movement or the training of thunderstorms. One of the other issues for this event was that it occurred on a Saturday evening where numerous large events were occurring which ended up cancelling or postponing to a later date.

Tornado filmed by multiple storm chasers and mainly went through farmland. One barn was hit and lost sheet metal on the roof. Tree damage was noted as well.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:53 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.
