A deep freeze is setting in across the Midwest with low temperatures forecast in the single digits and a few below zero, turning the season's first major snow into ice that's making some roads treacherous.

After snow on Friday and Saturday across much of the region, temperatures plunged behind the front today. The National Weather Service forecast 20 degrees or lower across six states from North Dakota to Illinois. Fargo, North Dakota could dip to 11 degrees by early Sunday. Madison, Wisconsin could see 7 degrees, Des Moines 12 and Chicago 9.

Parts of Iowa, northwest Illinois and southern Wisconsin could reach zero or below, the weather service said. The slow-moving storm that caused hundreds of canceled flights at Chicago's two airports is heading into Canada. The southern Wisconsin city of Janesville is digging out after the wintry storm dumped between 10 and 20 inches of snow by Saturday afternoon.

What does this mean for the tri-state area? This means that you may be having to start digging your car or truck out of the snow earlier in the season than you think. This also means roads, especially back roads and side streets, will be much more dangerous much sooner in this winter season than many of us may want. Watch out and take care!
