Severe thunderstorms generated very large hail and at least three tornadoes across southern Minnesota on April 13, 2026, as a stalled cold front extended from Redwood Falls, Minnesota, to Eau Claire, Wisconsin.
Preliminary assessments indicate hail up to 3.5 inches in diameter accompanied the storms, alongside tornadoes rated from EF-0 to low EF-1. One notable EF-1 tornado, with estimated 90 mph winds, tracked near Truman to Amboy, Minnesota, causing structural damage to farms, broken windows, and significant tree damage, according to the National Weather Service Twin Cities/Chanhassen. Official damage surveys are ongoing, with National Weather Service personnel collaborating with local emergency managers to finalize assessments.
For restoration contractors, homeowners, and insurance adjusters, these events signal a potential increase in claims related to structural damage, roof repairs, and debris removal. The combination of large hail and tornado-force winds can cause extensive damage to residential and commercial properties, requiring specialized expertise in water mitigation, structural repairs, and exterior envelope restoration. Homeowners in affected areas should document damage thoroughly for insurance claims, while adjusters will need to differentiate between hail and wind damage for accurate policy application.
The stalled cold front provided the necessary atmospheric instability and shear for the development of these severe weather phenomena. Such meteorological setups are common during the spring severe weather season in the Upper Midwest, often leading to multiple hazards. The National Weather Service issues severe thunderstorm warnings for hail exceeding one inch in diameter and wind gusts above 58 mph, and tornado warnings for observed or imminent tornado activity. Residents are advised to monitor official weather alerts and have emergency plans in place.
Further updates on damage assessments and official tornado ratings are expected in the coming days as survey teams complete their work. The National Weather Service Twin Cities/Chanhassen will publish final reports on its website. Affected property owners are encouraged to contact their insurance providers promptly and seek qualified, reputable restoration professionals for damage assessment and repair. Local emergency management agencies can also provide resources and guidance for recovery efforts.
