About Tornadoes in Caledonia
This overview was written July 24, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Caledonia sits in southeastern Wisconsin between Milwaukee and Racine, in the low country along the Lake Michigan shore. This corner of the Upper Midwest experiences tornadoes during the warm season, and while they are less frequent than on the plains, the open lakeside terrain allows organized storms to move through.
The tornado threat here follows the Midwestern recipe. Warm, moist air advancing north from the Gulf of Mexico meets cooler air over the region, and when a vigorous jet stream adds wind shear, thunderstorms can rotate and produce tornadoes. Lake Michigan influences the local weather — a cool lake breeze can stabilize the immediate shore, while the boundary it forms can focus storms a short distance inland. Activity concentrates from late spring into summer.
Tornado intensity is graded on the Enhanced Fujita (EF) scale, which assigns a rating from EF0 to EF5 based on the damage a tornado produces rather than a measured wind speed. Most events are weak, but stronger tornadoes do occur in Wisconsin when conditions align. The record for the Caledonia area — the number on file, how they distribute by decade and rating, and the notable events — is drawn from the NOAA Storm Prediction Center and shown in the figures elsewhere on this page.
