An upgraded hurricane system will bring gusts of wind to Michigan late today through Sunday. The cold will suddenly move into the back of the storm, and bring a rather heavy ring of lake-effect snow to areas in the snow strip.
Today the wind won’t be in the south and is only really strong against the southern shore of Lake Superior. By Sunday morning, the wind will turn to the Northwest. This will focus strong winds along the west coast of Lower Michigan and the west coast of Thumb.
Lower Southeast winds will have the lowest gusts of wind on Sundays from 35 mph to 45 mph.
The Lower Southwest will experience gusts of wind from 40 mph to 45 mph. All coastal areas south of Muskegon through Grand Haven, South Haven and Benton Harbor will experience gusts of wind from 45 mph to 50 mph on Sunday.
The lakeside areas in the northwest Lower and the UP shoreline will experience gusts of up to 50 mph. The eastern part of the Lake Superior shoreline can experience winds up to 70 miles per hour.
Below you can see the different wind directions today compared to Sunday where the maximum gust is concentrated in different areas.
Wave heights between 12 feet and 15 feet could lie in the dark red zone of the forecast maps below.
Therefore, the areas you expect will have wind advice and flood warnings along the lake.
Once cold air moves in, snow will form a lake effect. There is air cold enough up high to create moderate to thick snow. The real limiting factor would be too strong winds. Strong winds do not allow the air to stay on the lake long enough to create a truly dense strip of snow. When winds were above 25 mph, we found that the lake effect creation was limited.
Kalkaska, Fife Lake and Manton in the lower northwest are likely to have the most snow, over 4 inches. Surrounding areas, including parts of Traverse City, will be 2 to 4 inches long.
Most areas in the southwest Lower will see less than 1 inch of snowfall. There may be a few spots scattered up to 2 inches.
If you are not ready for the full winter weather, don’t worry. We have a big change in temperature coming and it will last for several weeks.
