(AREA) -- Overnight below-zero temperatures are predicted for Michigan as the state braces for the coldest air of winter. Meanwhile, DTE Energy still is pecking away at power outages caused by high winds over the weekend. By late afternoon Monday, the utility says 17,000 customers lack power compared to a peak of more than 120,000. The Thumb was hardest hit with 20 percent of the service area knocked offline. As of 10 a.m. Huron County still had 357 customers without electricity. Lapeer County has around 200, Sanilac County around 170, less than 50 in Tuscola County and St. Clair County residents are back online with only a handful still in the dark. DTE says electricity should be restored to 90 percent of customers before Tuesday as crews work 16-hour shifts. The National Weather Service says temperatures will fall below zero after midnight around the state. When the wind chill is considered, it will feel like 35 below zero in the western Upper Peninsula. From Lake Michigan east to the Thumb, high temperatures Tuesday won't get past 15 degrees.
