Millions of Americans have already felt portions of this bitter arctic air from the Polar Vortex sweeping across the U.S.
When there is a disruption in the Vortex, it becomes weak and pushes colder air south towards Canada and the U.S.
On top of a La Niña winter, this has caused us to see typical temperatures for early February to appear in December.
This new wave of Arctic air has already brought colder temperatures than what most of the country saw on Monday, where a Cold Weather Advisory was in effect for northern Montana and wind chills caused it to feel 20 to 30 degrees below zero.
