Total snow accumulations of 3-5 inches are possible.
The National Weather Service has posted a Winter Storm Watch for Wednesday, for all of Southeast Michigan, including Wayne, Oakland, Macomb, St. Clair, Livingston, Washtenaw, Lenawee, Lapeer, Monroe, Midland, Saginaw, Shiawassee and Genesee counties. Temperatures are expected to be in the mid-20s through the low 30s.
Snow will become lighter by Wednesday night and continue into Thursday before tapering off into flurries by the weekend. More is expected with lake enhancement in the Snowbelt.
WEDNESDAY: Mostly cloudy with snow showers.
This comes after metro Detroit got hit with the first big snowfall of the season Monday evening. It will likely be the coldest air the region has seen so far, with wind chills in the single digits to below zero.
It's blustery, windy and cold out there, and the Lake Erie waves are churning! Up to a foot of snow is expected for Jefferson, Oswego, and Lewis counties, with the highest amounts - 15 inches or more - falling over the Tug Hill Plateau. On the back side of the low, lake effect snow will set up, giving us additional snow for Wednesday and into Thursday.
Tired shovelers in Buffalo and Watertown should get a break with this round, however, as winds out of the northwest set up over the region, and steer the heaviest snow further south than the weekend's event. Overnight low temperatures will range from 10 to 25 degrees.
