Episode Narrative A very large and intense storm system that moved across the Upper Midwest generated one tornado in southern Minnesota during the late afternoon of Sunday, April 15th. Initially, a warm front laid across southern Minnesota, bisecting a very cool air mass in central Minnesota and a very mild air mass in southern Minnesota. Winds veered rapidly from the south, to the east-northeast across the area where the tornado formed. Although wind shear was strong, limited instability allowed most of the storms to remain weak, until the storms moved close to the warm front where the abrupt switch in the wind direction allowed for a tornado to form rapidly, but only last a few minutes as the storms moved into the stable air mass north of the warm front. In addition to the tornado, low freezing levels created some of the stronger storms to produce penny, up to quarter size hail. These storms moved into west central Wisconsin where some produced penny size hail.
Event Narrative A storm chaser observed a brief tornado touch down southwest of Brownton, Minnesota. No damage was observed as it tracked less than a few hundred feet in a open field.
