12z oper GFS's 29th NJ model impacter should not be summarily tossed... 

Not saying it's high confidence - how could I ... But typically the front side wave spaces, while major hemispheric mode changes are underway, are cyclogen active.   

In principle ...the period of time is okay for activation of storm systems.   Way too early to be detailed beyond...

Euro with the 582dm heights into WV/MD and 576 to the NY/PA borer to kick off December. That would be some impressive warmth ahead of the cold front into the mi-Atlantic and parts of the Northeast (unless there happens to be any wedging).

Yup...we briefly get a shot of cold air behind the post Thanksgiving time frame and then pup heights right back up ahead of the next system. But hopefully we really do start changing things after that front later in the first week of December. Praying we really do start building heights and ridging into the West so we stop with this building heights ahead of systems, then getting a shot of cold air, only to build heights up as the next trough digging into the west translates east. If we can sustained riding in the west...we won't have to completely worry about that...especially if we can then get some Arctic support on our side.

really liking the progression on all the ensembles as we head into the first week of Dec

initial equatorward jet extension -> T-day trough establishes cold along with building -EPO/-WPO

trough moves into the N ATL and increases Scandi ridging -> second trough dumps cold into the West and Canada

second jet extension pushes cold east -> N ATL trough strengthens and starts pushing Scandi ridging into the NAO region

Let's really, really hope the PAC plays out and evolves like that. But even if it doesn't...if it can at least evolve to a degree where we can continue to further develop that later in the month...that would be a big change. I also wouldn't mind maintaining a stronger SE ridge...coastal peeps may not want that and of course that could be playing Russian Roulette but that would at least help with an active storm track with ejecting shortwaves from the southwest...then we just hope for a perfect trough axis to our west.
