| Brief Description: Border Crosser, went into Minnehaha County, SD at 1500CST. Intense thunderstorms developed ahead of an approaching cold front. This line was the first wave of storms to form. The bulk of the severe weather passed to the west and north of Iowa. One very large cell formed over the northwest corner of the state. It produced a tornado northwest of Larchwood, in the northwest corner of Lyon County. Buildings were damaged on three farms. A total of 10 buildings were destroyed as well as two silos. On one of the farms, the owner watched as a 1500 pound fertilizer tank was lifted 50 feet into the air and blew past his window.

The tornado passed into southeast South Dakota shortly after this damage occurred. It was a border crossing tornado. | |||||||||||
