Episode Narrative Thunderstorms developed along and ahead of a cold front as it encountered moist and unstable air across Wisconsin.

A record number of tornadoes for April struck Wisconsin on April 10. Fifteen twisters affected the state as a strong spring storm moved across the western Great Lakes. In the National Weather Service Green Bay service area of northeast Wisconsin, ten tornadoes were reported, a record single-day outbreak for any month of the year.

In addition to the tornadoes, the lines of thunderstorms that developed produced plenty of straight line wind damage and large hail. Wind gusts, some estimated in the 80 mph to 100 mph range, downed numerous trees, damaged a small building, caused an injury and damage to two homes, toppled an 80-foot tall radio tower, threw a carport two houses away, and caused major damage to two industrial buildings. The largest hail reported was baseball size near Winneconne in Winnebago County.
Event Narrative A tornado developed about 3.5 miles southeast of Argonne and moved northeast into Florence County. The storm uprooted and snapped hundreds of trees, some of which fell on vacation cabins along the storm's path. The hardest hit area was several miles east of Argonne shortly after the tornado developed. A large part of the roof of a house was removed (DI 2, DOD 6). The tornado continued northeast into Florence County at 7:46 pm CDT (1846 CST). The average width of the tornado was 250 yards.
