A cold front moved across Minnesota during the day on the 19th. Ahead of the front was a very moist and extremely unstable air mass along with a warm front. Strong wind shear was also in place, especially in the vicinity of the warm front and with a low-level jet pushing into the area as well. These ingredients led to storm development across central Minnesota by mid-afternoon with one storm becoming a dominant supercell that produced very large hail over a wide area, with some of that large hail being driven by winds in excess of 60 mph. As the storm crossed I-35, upwards of 20 cars experienced broken windshields with many of the cars being trapped on the highway as the most intense part of the storm crossed the highway in the middle of a construction zone where traffic was at a standstill due to the construction and heavy weekend vacation traffic from the Minneapolis-St. Paul area. This storm then crossed into Wisconsin and continued to produce large hail and sporadic wind damage, along with a few funnel clouds. Heading into the evening hours, this storm evolved upscale into a large MCS that caused large amounts of damage across parts of Wisconsin. Additional storms were seen ahead of the large supercell that led to additional wind and hail damage as well.
