A low pressure system moving out of the Central Plains brought a warm front through Minnesota and northwest Wisconsin during the morning hours. Supported by a strong low level jet and warm air pushing into the region, storms spread north through the morning hours. The first round of storms mainly produced hail with the largest being tennis ball sized. A cold front associated with the low then moved through during the afternoon leading to another round of storms that produced hail to the size of quarters. Insurance companies estimated $10 million in property and automobile claims from the storms in Washburn County alone.
