A major winter storm will bring snow into Southwest Michigan by early tonight. The snow will be heavy at times north of a line from Muskegon to Alma and continue into Thursday morning with accumulations of 12 to 16 inches. South of that line, the snow will mix with sleet and freezing rain after midnight. Near Interstate 69 expect the precipitation to change to all rain for a time Wednesday morning. As the strong low pressure system tracks across central Lower Michigan Wednesday afternoon, it will draw much colder arctic air in behind it on very strong gusty winds. This will change the precipitation to all snow by mid afternoon Wednesday. Strong and gusty winds, combined with falling temperature and snow (which will be heavy at times once again), will make travel through Southwest Lower Michigan dangerous Wednesday night into Thursday morning as near blizzard conditions are expected with visibilities frequently near zero miles and wind chills near zero degrees.
By 1 PM this afternoon the snow will have reached eastern Wisconsin. Heavy snow will be falling over Nebraska and Kansas.
By 7 AM Wednesday morning, the center of the storm will be near Chicargo and snow will have spread across all of Lower Michigan. The snow to rain line will be moving north into the I-69 area.
By 7 AM Thursday morning the storm's center will be moving northeast acorss Lake Huron. By then very strong winds, snow and blowing slow will cover all of Southwest Michigan.
This is the total snowfall expected across the central United States and Great Lakes through Friday morning.
