Severe Weather Alerts in WisconsinWisconsin Frequent Weather Alerts:
Severe thunderstorms, hail, wind tornadoes, wind, extreme cold

Wisconsin generally has warm summers and cold winters with plenty of snow. It does have its major temperature extremes, as well as some severe weather. While it doesn’t happen often, it is still worth knowing all the weather alerts.

Wisconsin can suffer thunderstorms and large hailstones, both of which are common due to the precipitation in the state. In southeast Wisconsin, a big threat is the wind, wind that can be stronger than most thunderstorms. Some records even show wind reaching 100 miles per hour, and that’s without any severe weather causing it.

Tornadoes, while not as common as states in Tornado Alley, occur fairly frequently with an average of about 23 per year. They can bring with them the damaging winds and heavy rain that cause real damage. The tornado season goes from April to September, and most of them strike in the evening or late afternoon. Severe thunderstorms moving in from the Great Plains are common in late spring and summer, and Wisconsin can even experience the remnants of tropical storms formed in the Gulf of Mexico.

Blizzards are not uncommon in the winter along with extreme cold temperatures in the northern part of the state.
