Heavy lake effect snow to fall in some parts of the thumb, SE Michigan

Lake effect winter storm warnings are in effect for Sanilac and St. Clair counties for 4-8" of fluffy snow. Temperatures are definitely at the point where snowfall ratios will be 12-15:1, which should enhance the accumulation totals.

The precipitation mode of the storm coming at the end of the week is still highly questionable. I'll post more updates as things come into focus, but for now it's all clear as mud.
