The previous winter weather advisory has been beefed up to a winter storm warning for the counties below, shaded in pink.
The winter storm warning covers Holland, Muskegon, Grand Rapids, Big Rapids, Alma, Mount Pleasant, Saginaw, Midland, Bay City, Caro and Bad Axe. The winter storm warning is in effect now since the snow has started. An area around Grand Rapids and west of Grand Rapids has already reported 2 to 4 inches of snow as of 9:00 p.m. The winter storm warning continues until 10:00 a.m. Sunday. This end time gives you a good feel for when the accumulating snow will fall. It’s an overnight and early Sunday morning snowstorm.
South of the winter storm warning is a winter weather advisory for a mixture of snow, freezing rain and sleet. Kalamazoo, Lansing, Jackson, Flint, Lapeer and Sandusky are in the winter weather advisory. You can expect up to 2 inches of snow and one-tenth of an inch of ice accumulation.
Ann Arbor, Detroit and Oakland County are not in any winter weather advisory. You’ll look for light accumulations of snow, sleet or freezing rain.
On the north side of the winter storm warning is a winter weather advisory for 3 to 5 inches of snow. This includes Ludington, Cadillac, Houghton Lake, Gladwin, Standish, Tawas, Oscoda and Alpena. Traverse City is not in the winter weather advisory area.
Here is the latest output from the human meteorologists at the National Weather Service. They use all of the models to create the forecast.
Look for a lot of snow reports of 6 inches to 7 inches from the Grand Rapids area and Muskegon to Saginaw, Bay Ctiy, Midland and the northern Thumb. There may be an isolated spot or two that gets 8 inches of snow.
Flint and Lansing should get around 4 inches of snow.
Kalamazoo, Jackson, Ann Arbor and Detroit are in the 1 to 3 inch band of snow. The farther south you are, the more you can plan on 1 inch and not 3 inches.
North of the heavy snow area, Traverse City should get 2 to 3 inches of snow.
The snow should be over by 7:00 a.m. on the west side of Michigan and by 10:00 a.m. on the east side.
