Thunderstorms brought damaging winds, hail, very heavy rain, and a brief tornado, as they moved across central and east central Wisconsin starting in the late afternoon of June 25th, and continuing into the early morning hours of June 26th. The storms downed numerous trees and power lines at many locations as they passed. Thunderstorm winds also tore the roof from a silo and caused shingle and siding damage to a house and garage north of Black Creek (Outagamie Co.), knocked trees onto a house and a car near Seymour (Outagamie Co.), and produced a downburst wind of at least 75 mph that snapped and uprooted trees south of Nichols (Outagamie Co.).||A weak tornado that touched down east-southeast of Symco (Waupaca Co.) snapped and uprooted trees, and damaged several buildings at a farm.

A weak tornado formed 4.2 miles east-southeast of Symco and traveled east just under three miles. At least a half dozen pine trees were snapped along the path and several large trees were uprooted (DI 28, DOD 3,4). Several farm outbuildings were heavily damaged, with metal from the buildings strewn downwind hundreds of yards. A manufactured home was pushed off its block foundation (DI 3, DOD 3). The tornado dissipated about 6.3 miles north-northeast of Northport. Average path width was 75 yards.

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.
