Nah, Michigan is outside both the traditional "tornado alley" and the secondary major tornado zone in the Ohio Valley known colloquially as "Hoosier Alley", named for the relative frequency of violent, long-tracked tornadoes in Indiana, Ohio, Kentucky, etc. given the relatively lower number of tornadoes they have to the traditional tornado alley. Michigan has only had two F5 tornadoes in its history, and none since 1956.

Yeah, in another life, I might be applying to meteorology grad school instead of history grad school. This is relevant to me too, since I'll also likely be moving to Michigan in the fall.
