GFS dffferences begin at hour 84. Trof is less deeper and more progressive with the s/w we are watching. Much stronger s/w coming down from Canada to the WA coast
Well this is different. At H5, it has a northern stream S/W diving into the picture just north of the Dakotas, directly in line with our H5 closed off vort centered over NE
Confluence, blocking is a tiny bit less, but with 0z it also looked "bad" at this timeframe before that bitch got the heavy shove south of us...I'd advise waiting to draw any conclusions at this point.
