Thunderstorm Wind in Lake County, Minnesota

The top part of a healthy pine tree was knocked over by the wind and punctured a garage roof.

An area of low pressure lifted a warm front into the Northland during the day on the 26th. Behind this warm front was a moist and unstable airmass and daytime heating led to the development of strong to severe storms over northern Minnesota that moved to the southeast during the evening hours. One of the first storms was a supercell that produced hail 3 inches in diameter. Later storms continued to produce hail and damage to trees as they moved across the region. The Grand Rapids area in particular was hit hard in this event with widespread tree damage across the city. The KDLH radar was inoperable for this event but a high level of service was maintained by utilizing the KMVX and KMPX radars and one minute GOES-16 satellite data.
