That is part of why January was such an epic disaster, despite the fact that it was uber active and SNE snowfall is generally more highly correlated to precip, than temps. Normally, that would have still been a decent to very good month for snowfall, but all of the cold got locked into Siberia and the PNA was constantly west based, which funneled any morsel of cold that managed to sneak onto this side of the globe into the west.
