Is the Pacific uncooperative though? If we keep trending towards blocking and an eastern trough, you're going to get a ridge out west even if it isn’t in a perfect position and a true +PNA look. The pacific jet will be sort of irrelevant because the only way you’re scoring anyways is to have an anchored high north of us, which will feed the cold. Point being, I’m not exactly fretting about Pacific air when we have a continental source to tap into. Another thing. If we keep getting blocking, that ridge is going west. It won’t be your quintessential +PNA look, but an Idaho/Montana ridge works here. Heck, a Seattle ridge tends to leave room for storms to cut.
