An arctic cold front is slipping south through Lower Michigan this morning. Our temperatures and wind conditions are going to change through the day, eventually leaving us with the coldest day of the winter so far.

The new type of air blowing in from the north will take temperatures into the 20s and then teens across southern Lower Michigan. This should all happen by early afternoon.

Here are the current temperatures.
