Cold air masses are manufactured over the frozen snowfields of the Arctic.
Across that desolate territory, there is little or no effective sunlight from
November through January. The snow and the ice act in two ways to chill the
air. First, any warmth that might exist is radiated into outer space. Second,
the snow insulates the air from any ground warmth.

Cold waves happen in the United States when the jet stream takes on high
amplitude. This dislodges the cold from arctic regions and forces it to plunge
southward.

During the middle and late parts of the week, the above scenario will play out
as it turns significantly colder across the Midwest. No records will be set,
but rest assured you will notice the difference.
