Overview

During the early morning hours of July 12th, a line of severe storms tracked from central Minnesota into western Wisconsin.  This line of storms created widespread damaging straight line winds across Anoka and northern Washington Counties in eastern Minnesota, with the damaging winds continuing into northwest St. Croix and southwestern Polk counties in western Wisconsin. Within this broad swath of damaging winds, there were four tornadoes.  In East Bethel, Columbus, Wyoming, southern Forest Lake, and Hugo, two tornadoes occurred, both with concentrated paths of more significant damage. Two more tornadoes occurred elsewhere:  one touched down southeast of Chisago City and the other hit Warner Nature Center and surrounding areas, southwest of Marine on St. Croix.
