Thunderstorm Wind in Menominee (c) County, Wisconsin

Thunderstorm winds downed multiple trees and power lines across Keshena. Highway 55 had to be closed due to downed trees in the road. The time of this event is an estimate based on radar data.

Thunderstorms developed in the Dakotas on the night of June 10th in response to very warm and humid air interacting with a stalled frontal system. The line of storms moved across Minnesota and into western Wisconsin on the morning of June 11th and continued across much of central, north central and northeast Wisconsin during the late morning and early afternoon hours.

The storms produced damaging winds, mainly north of Highway 29, downing numerous trees and power lines, flattening at least 2 barns, and causing roof damage to several other buildings. At one point, 55,000 people were without power.
