What happened
The episode as NWS DMX wrote it up.
A warm front moved north across Iowa during the late afternoon and evening hours. Thunderstorms erupted north of the front. Most of the storms were general thunderstorms, however a few did become severe as the moved across Kossuth County. High winds around 75 MPH blew through west of Irvington. Six homes and outbuildings sustained damage. Windows were broken out of several parked cars, a few grain bins were damaged, and the roof was taken off of one house. A short time later, 58 MPH winds were recorded at the AWOS site in Algona. Though these winds were not directly the result of the thunderstorms, they were the result of the outflow from the collapse of one of them.
