Weather 4WarnToday is a 4Warn weather day.

Weather alerts

  • Winter storm warning in effect for Wayne, Washtenaw, Oakland, Macomb, Monroe, St. Clair, Sanilac and Lenawee counties through tonight.

  • Winter weather advisory for the rest of southeast Michigan until 10 p.m.

The moment

Although some light snow appears to cross the state line from the south early this morning, the timing of more widespread snow is expected to begin around sunrise and then intensify throughout the morning. That initial light dusting might be just enough buildup for slippery conditions for morning rush hour driving in the Detroit metro area.

We expect a small lull mid-morning before the storm intensifies around 10 a.m., with a noticeable spike in coverage and intensity in the afternoon.

A band of heavy snow is then expected between 10 a.m. and 4 p.m., approximately centered on a line from Adrian through Metro Detroit to Port Huron. A snowfall rate of 1 inch per hour is likely during this period, creating significant implications for travel this evening.

Snowfall appears to diminish around 7 p.m. until late evening.

Snow Totals

Most of southeast Michigan will see 4 to 5 inches of snow, with areas downriver expected to grow 6 inches for a 12 to 2 p.m. Wednesday. The higher studs, favored for those south of I-94, could reach closer to 5 to 6 inches.

The highest accumulations will most likely occur around the Michigan/Indiana/Ohio state line, but the system’s track also places downstream in an area favorable for a slightly extended period of moderate to heavy snowfall.

North towards the I-69 corridor, especially in the Flint area, 3-4 inches will be more reasonable, as the highest rates largely bypass this area to the east/southeast.

In the Thumb area, some lake improvement will occur from late afternoon through evening and will bring local amounts of 5 inches or more as snow accumulation persists for several more hours.

More snow rounds

Beyond this storm system, expect a more wintry pattern to return Friday into the weekend with cold and occasionally snowy conditions persisting into early next week. After a clipper system brought light snowfall on Friday/Friday evening, a larger system could impact parts of the region by the end of this weekend. This will be the next system with widespread snow accumulation for our region. Temperatures will be noticeably cooler through next week with highs in the low to mid 20s and low single digits to lows in the teens for overnight lows.
