Tracking hail, high-wind, and tornado reports across Wisconsin? This page aggregates 2962 severe weather events recorded in 71 Wisconsin counties over the last 12 months, including hail up to 4.5" and wind gusts up to 100 mph — every one sourced directly from official National Weather Service alerts and Storm Prediction Center verified reports. Pick a county for its day-by-day storm log, radar snapshots, and official warning excerpts.
No active hail or wind alerts are posted for Wisconsin right now, and the SPC discussions don’t place the main severe threat over WI today. The closest broader setup is a late-Monday into Monday night corridor from the central Great Plains into the Upper Midwest, where thunderstorms could bring some severe risk, but SPC’s more immediate large hail and damaging wind focus is farther south over the central/southern Plains and Ozarks.
Statewide maxima from SPC verified reports and NWS warnings, last 12 months. Tornado EF ratings are assigned by NWS survey teams after ground surveys and published in NOAA's final storm records.

How Wisconsin compares nationally
Ranked by SPC verified storm reports (wind, hail, tornado) across all 50 states over the last 12 months. Severity-weighted index scores each report by hazard (tornado ×20, hail ×4, wind ×1) so a single derecho's flood of wind reports doesn't outweigh tornado outbreaks. Recalculated daily as of Sep 11, 2026.
