It’s believed to be the coldest air to hit southeast Michigan in 20 years.
The weather has also contributed to at least six deaths.
Most schools in the state closed and municipal services are again delayed in some areas.
In these frigid temperatures, salt doesn't work.
While drivers can get around, Gov. Rick Snyder encourages them to drive slowly or stay inside.
Shortly before 9 a.m. Tuesday, it was -11 in Mt. Clemens, -12 in Pontiac, -13 in Ann Arbor, -10 in Howell, -9 in Monroe, -10 in Flint, 3 degrees in Grand Rapids and -10 degrees in Lansing.
The lowest temperature reported this morning in Michigan was 20 degrees below zero in the Upper Peninsula community of Ironwood.
Snyder’s main message to Michiganders: “Slow down, please. Then slow down some more. And stay inside. …This isn’t the day to have the kids go out and build a snowman or an igloo.”
Only Lansing had requested help from the state after the snowstorm, including the use of four-by-four vehicles and snowplows.
