The cold air affecting such far parts of the US has been due to extensive low pressure across eastern Canada. That is going to change in about a week. That low that draws cold air south will push off to sea.
The snow storms in the south and these great east coast snow storms will come to an end. Upper level low pressure across the east will be replaced with a more zonal flow resluting in an end to the continuous feed of cold air that has been coming in from the arctic. All GFS runs agree that the ULL will begin to turn more zonal starting in just a week from now.
Check the 5oomb GFS for yourself. Consistancy is the name of the game.
