Both the NAM and Euro have a 1060mb+ within 48hrs in Alberta. This is one of the bigger high's we have seen in awhile. Central Canada is cold and evident with the Polar air mass currently in place. The Siberian air our friend
orangeblood has been tracking is now making it's way into Alaskan/Yukon border. It's going to hang around until the Arctic front comes through.

Our big HP
1055mb right now in far NW Canada and building

That's not it, Euro (using wxbell) as mentioned has another massive HP cell (1060mb as well in Montana) to follow at the end of it's run with deep cold anomalies drilled down the great plains. As with most great arctic attacks it just comes and comes until it all comes crashing down. As long as the Alaskan ridge sits (which now progs to enter the adjacent arctic regions) it's a factory for strong HP.
