Event Summary:

During the late afternoon and evening of 17 June 2012, an upper level disturbance tracking across the Northern Plains interacted with a moist and unstable airmass over northeastern South Dakota and west-central Minnesota resulting in the development of scattered severe thunderstorms. The most severe damage occurred near the communities of Peever and Big Stone City in South Dakota and Ortonville, Minnesota. Numerous tree and power poles were reported down in this area, with significant damage to several homes and businesses. Cramer's Resort on Big Stone Lake also suffered fairly extensive damage.

In addition to the tornadoes, large hail was reported over Brown, Marshall, and Codington Counties, including some to the size of tennis balls (2" or greater in diameter). Significant crop damage was reported from the hail with several vehicles sustaining damage.
