Arctic Air Influx begins

The Arctic Air expanses have opened up to the North US.
In the above current analysis, the low pressure associated with the cold fronts responsible with this air continues to move off east, bringing that cold air along.
The high pressure stationed over the Dakotas will not assist much in relief to the cold, but a warm front close to that high pressure may bring warmer temperatures to that area.
We can see how far that cold stretches as the cold front bottoms out in the South, going through the Texas area.
People in the Midwest will see significantly colder temperatures, with cities such as Chicago, Green Bay, and Madison (WI) seeing below 0 low temperatures.
