Severe Weather of Northeast and North-Central Wisconsin

Updated with 2012 Reports.

Severe weather statistics for northeast Wisconsin are available here.  The stats were compiled for the period 1950-2011.  (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.
