WISCONSIN — Severe weather season is approaching for Wisconsin. Lets take a closer look at tornadoes and how they have impacted the state in the past.

Tornadoes can occur at nearly any point in the year in Wisconsin; February is the only month with zero tornadoes on record. However, the peak season for tornadoes arrives with warmer temperatures. May, June, July, and August bring the most tornado days, with the peak occurring in June.
