DETROIT – A winter weather advisory is in effect for Lapeer, Macomb, Oakland, Sanilac and St. Clair counties from noon to 7 p.m. Monday.
Dry weather persists overnight as it gets colder. Snow arrives tomorrow and it will accumulate on paved surfaces as well as grassy areas.
Monday’s most treacherous times of day will be midday, afternoon and evening. Any snow that piles up will melt during the ensuing days with higher daytime temperatures.
Sunday night becomes mostly cloudy and chilly. Overnight lows will be in the low 30s.
Sunrise is at 6:48 a.m.
Cold air remains in place from Sunday to Monday. This is key because our next frontal system arrives. When it does, it will be cloudy for the start of the morning commute. By mid-morning, those clouds produce snow.
It will be snowy, slushy and cold the rest of the morning and into the afternoon and evening.
Snow timeline
Here is a more specific snow timeline for you and your family on Monday:
- Until 11 a.m: Cold, cloudy and dry.
- 11 a.m. to 1 p.m.: Snow arrives from the south. Cities and towns south of I-94, in Lenawee and Monroe Counties, receive the first flakes. Temps will be in the low 30s.
- 1 p.m. to 2 p.m.: Snow takes over Detroit and all of Southeast Michigan from the thumb to the Michigan-Ohio Border. Temps in the low and mid 30s.
- After 2 p.m.: Steady snow falls across Detroit and all of Southeast Michigan for the afternoon commute and the dinner hour. Temps in the middle and upper 30s.
Midday and afternoon travel will be disrupted significantly because snow will accumulate not only on grassy areas, but on highways, streets and sidewalks as well.

- Lenawee and Monroe counties (our South Zone): Up to one or two inches of snow.
