A Spring Snowstorm For The Record Books

 

On May 10, 1990, eastern Wisconsin experienced its latest snowstorm on record.  The snow was very wet and heavy, and unfortunately it occurred when most trees and other plants had just leafed out for the new season.  As a result, thousands of trees and tree branches came down under the weight of the heavy snow.  Many power-lines snapped as the trees/branches came down.

Below is a rough plot of the snow amounts along with a 6-inch contour line. 

Below is a Storm Data event narrative for the snowstorm.  Click on the image for a larger version.
