Lake-Effect Snow — Mackinac, Michigan

2013-01-25 · Mackinac, Michigan

Wider weather episode

Very cold air was in place over the region, in advance of a clipper moving southeast from central Canada. The clipper was moisture-starved, and would only produce very light snow away from the Great Lakes. However, southwest winds ahead of the clipper interacted with pre-existing lake effect snow to produce very heavy snow in western Mackinac County. Engadine picked up 8 inches of snow, while media reports indicated Curtis ended up with nearly two feet of fresh snow.
