Almost half the nation now covered compared to 23% this time last year. And it’s only mid December. Cool Temps across the Nation will help keep the snowpack on the ground and that snowpack will in turn help keep the surface cool.
Snow & ice Map shows a frozen over Hudson Bay. The winds from there have no resistance now so the cold air flow will be easier to reach the U.S.
