Severe Weather of Northeast and North-Central Wisconsin
Severe weather statistics for northeast Wisconsin, by county, month, decade, and EF Scale rating are available below. The stats were compiled for the period 1950-2012. (The most recent year's data will be compiled and updated during the winter.) Please note that severe weather data from the 1950s-1970s are not as complete as more recent years due to improved spotter networks/reporting procedures and more detailed post-storm analysis.
