According to a National Weather Service discussion, parts of the Midwest will be 30 degrees below normal during the middle of next week due to a compact Arctic upper low that could trek over the Great Lakes. Much of the rest of the eastern United States could see temperatures from 10 to 25 degrees below normal.

The temperature in Chicago is forecast to drop to minus 15, with a possible wind chill of minus 30. Similar weather is forecast in Detroit and Milwaukee.
