A damaging outbreak of strong tornadoes impacted the Great Lakes region of the United States from June 22 to June 23.
The most significant activity occurred on the 22nd, including a high-end EF1 tornado that damaged numerous structures in Portland, Michigan early that afternoon.
Later that evening, a strong, rain-wrapped EF3 partially debarked trees and swept away an unanchored house near Lovilia, Iowa, before weakening and striking the town of Albia at EF1 strength.
A separate EF2 tornado from the same cell heavily damaged homes and businesses west of Albia as well.
As the evening progressed, numerous tornadoes began touching down across northern Illinois and in Michigan as well.
An EF2 struck the south side of Edgington, Illinois, tearing roofs off of homes, destroying garages, and snapping large trees.
Another large EF2 wedge tornado caused major damage at the Woodhaven Lakes Campground near Sublette, flattening a large swath of trees, destroying or tossing numerous recreational vehicles and mobile homes, and injuring seven people.
In Michigan, an EF2 tornado severely damaged two homes and downed numerous trees near the town of Millington.

The strongest and most destructive tornado of the outbreak initially touched down after dark as a weak tornado south of Morris, Illinois, causing roof and chimney damage to homes, and downing trees and power poles as it moved along a southeasterly path.
The storm intensified and widened rapidly as it entered Coal City, reaching nearly a mile wide in diameter and attaining high-end EF3 strength.
Numerous anchor-bolted frame homes in Coal City were damaged or destroyed, and a few were leveled or swept from their foundations (though vehicles parked at these residences were not moved, and nearby vegetation was not defoliated or debarked, precluding a higher rating).
Two large high-tension metal truss towers were toppled to the ground in Coal City as well.
The tornado weakened to EF2 strength as it struck the neighboring town of Braidwood, heavily damaging trees, power poles, and a motel in the southwestern part of town.
The tornado moved out of Braidwood and maintained EF2 strength as it continued along its southeasterly path through rural areas, rolling a recreational vehicle, damaging the roof of a frame home, snapping numerous power poles, and completely destroying an outbuilding before dissipating.
The outbreak continued the following day as a few weak tornadoes were observed in Michigan, Ohio, and Massachusetts.
Overall, this outbreak produced 28 tornadoes, though no fatalities occurred.
