Widespread snow will move back into Metro Detroit around midnight as a low-pressure system tracks northeast through the Ohio Valley. Nighttime sleet and snow accumulations will total 1 to 3 inches. Northeasterly winds will be 5 to 10 mph with gusts up to 20 mph.

Sunday

Heavy snow is expected Sunday morning. Snow will be more intense on the eastside of Southeast Michigan and closer to Lake Huron, where snowfall will be enhanced by moisture from Lake Huron. Temperatures will be in the mid 20s to 30 degrees in the morning, and they will fall during the day. Winds will increase and shift from northerly to northwesterly. During the afternoon, sustained winds will be 10 to 20 mph with gusts up to 35 mph. These gusty winds will lead to blowing snow in some communities.

About 5 to 7 inches of snow are possible in much of Metro Detroit on Sunday. (WDIV)
