Event narrative

A 63 mph wind gust was recorded on a personal weather station just northeast of Minneota.

Wider weather episode

A weak wave lifting out of the central Rockies aided in initiation of a forward propagating Mesoscale Convective system from the lee of the Black Hills southward into the Nebraska Panhandle. With abundant MUCAPE up to nearly 4000 J/kg and DCAPE up to 1500 J/kg, but deep-layer shear only around 20-25 knots, storms retained a somewhat outflow dominant character while on an east-northeast trek. Winds were generally from 60 to 80 mph with significant damage to trees and a few structures along the track of the system north of Interstate 90 into southwest Minnesota.
