You can really see that scanning through the snowfall maps from day 11-15 on the EPS. Lots of tracks that look like they originate in Canada and slide down the western ridge as they move east as the SS is pushed south. Could be a miller b type patter with some blocking showing signs of life just after day 10. The hope would be as the cold relaxes but with the block in tact post day 15, that they could meet up near us.
