This snow pack as modified the overlying air, which has promoted the colder temperatures witnessed across the north. With each successive wave within the overall pattern, parts of this cold modified air are able to propagate into parts of the CONUS.

The polar vortex is simply a large scale cyclonic circulation that is centered over the polar regions of Earth. This “Vortex” is not anomalous from the Earth’s weather, as it has always been and always will be a constant variable that affects the weather that humans see. The term “Polar Vortex” has been misconstrued within the mainstream media as something that is unusual and of which should be feared as it is bringing cold and snowy weather to the lower 48 (CONUS). The cold and snowy weather that has been witnessed across much of the lower 48 this year is a result of a persistent ridge over the West Coast and troughy pattern over the central US. This pattern has allowed for continental polar and arctic air masses to propagate from the snow packed regions of Canada and the Arctic Circle south to southeasterly into regions such as Minnesota. Because of this persistent pattern and its reluctance to decay, a decent snow pack has formed over the regions Canada and the Arctic.
