Well, I think it moved in the wrong direction all around. Right from the beginning, the macroscale waveguide across the Pacific was flatter. That's a dagger every time, no exceptions.
Looks like the beginning stages of a +EPO vortex to me. Euro loves to torque troughs SW along mountainous terrain so maybe it pulls one of its BS stunts in that regard but overall, right from day one I don't like the look of the run.
Need to amplify that waveguide to dig the trough. Otherwise it's a flatter wavetrain, more progressive US trough, and a quicker/easier return to a +EPO/+AO as 120E forcing takes over. Bad run.
That's true, but the waveguide out of the NEPAC flattened for some reason, hence the front makes less progress. Probably a fluke but verbatim it's pedestrian.
Lol..reload attempt in clown range. Less of a Hudson Bay Vortex also helping. Man look at all that blue..

Verbatim, the GFS is showing all-time record cold over much of the US (by mid-December standards). Longstanding records would come crashing down in lots of places.
Lol, 00z GFS already ridiculously different with the longwave progression at 72hrs across the hemisphere. For whatever reason this model is struggling w/ the ongoing pattern.
