Where did he say the GFS was colder then the NAM? Don’t see that at all.
And here are the 30hr graphics to show my point. NAM is colder then the GFS At the surface but they are both a torch at 850.
Correct. Also just using the NAM as an example. Look at how the heights elongate westward in Canada as a result of the stronger southern s/w. This allows heights ahead to be pumped up just enough.
Probably right and as you said, there has been a steady but slow northward trend in warmth at all levels on this one for about 2 days now. Suck that they are sort of forced to throw out maps 4 days out.
It’s a pretty strong low over the appalachians to begin with. Pretty strong southerly flow to begin with. I said it many days ago that I did. Not like the trajectory it was coming at us. Pretty high latitude for a southern stream system.
