January 3-5 Lake Effect Snow (Great Lakes Affected)

Hour 90 of 12z GFS
As the system that will be bringing harshly cold air into the US departs, this cold air will work quickly to ignite the lake effect snow system for the Great Lakes. This lake effect snow, while it may not stick, the snow may be enough to coat the ground. Here's the forecast snow depth from the 18z GFS.
The snowfall from the lake effect snow may put down up to a foot of snow up in the far northern reaches of Michigan. Lake Michigan may put down up to 6 inches of snow, with lesser accumulation in the eastern Great Lakes.
