A Winter Weather Advisory is in effect from now on Sunday morning through 8 p.m. this Sunday evening.
The Winter Weather Advisory is for St. Clair, Livingston, Oakland, Macomb, Washtenaw, Ingham, Calhoun and Jackson Counties. This includes Detroit, Ann Arbor, Warren, Pontiac Howell, Adrian, Monroe, Port Huron, Lansing, Battle Creek and Jackson.
Rain should mix with and at times change to snow this morning over southeast and south-central Lower Michigan. The snow could come down at a moderate clip at times. When the moderate snow is happening, the Winter Weather Advisory areas could see a quick one to four inches of snow. The periods of snow will continue into early evening.
The snow totals will mostly be one to two inches, but a few isolated spots could get three or four inches.
The heaviest snow is expected to run in a swath from Port Huron to Oakland County to Ann Arbor, Adrian and Jackson.
Here’s the always updated radar loop.
One condition to note is temperatures will be just marginal for snow accumulation. When the snow is coming down harder, the temperature may drop to 32 degrees. When the snow lets up, the temperature will warm up to 34 degrees. Some of this accumulation will be what I call temporary accumulation. You could get a quick three inches that only stacks up that tall for a few hours then shrinks back to an inch or two.
While the grass and trees are the most likely spots for accumulation, there could be some slushy accumulation on the roads during the heaviest rate of snow.
The rest of Lower Michigan should have less than one inch of snow.
The precipitation will end this evening. The Winter Weather Advisory has been issued so you are aware of the first possible slushy roads situation in southeast Lower Michigan.
