2012-12-11 · Mackinac, Michigan

Wider weather episode

A low pressure system passed north of Lake Superior late on the 11th, with cold air already in place across Northern Michigan. Southwest winds just ahead of the system produced locally heavy lake effect snow in Eastern Upper Michigan, with 6 to 8 inches of accumulation near Engadine. As winds veered, heavy snow was displaced into far Northern Lower Michigan, with around a foot of new snow in the Mullett Lake area.
