On July 18th, a nearly stationary cold front extended across northern Wisconsin into central Minnesota. Not long after sunrise, a small complex of thunderstorms developed over eastern Minnesota ahead of the cold front. As these storms move southeast into western Wisconsin they produced large hail, damaging winds and localized flooding over parts of Trempealeau, Jackson and Monroe Counties.
