We were tracking this high since 300hr GFS and it's still there. Details as how strong HP is and cold air (-45 to -50s) in southern/southwest Canada certainly will play a role as depicted by the model. If there is a 1055+ hp cell system sitting on the US/Canadian border it's not going to pretty for wxman57.
It has DFW sub 30 for the rest of it's good resolution run once the big front passes. That's a good 2+ days.
Definitely some cold air in Western Canada. Check out the lows on this site. http://www.eldoradocountyweather.com/cl ... remes=Cana
