Juliasb, I heard about the storms and 6 confirmed tornadoes, and was surprised that the greater Detroit area was hit. So glad that you and your home were minimally impacted. This was not a good week to be with out power! So hot and humid.
Michigan has frequent tornadoes in the spring and summer months. Global warming? Who knows. I remember them as a child and my hometown, Kalamazoo, had a humdinger in 1980 that changed the face of our downtown for ever. Massive loss of historic trees and some buildings.
