This hemispheric pattern is about as close to perfect as it gets, and this might sound like a hot take, but I actually like the -PNA more than +PNA in this case. Why?
The -PNA will try to amp the SE ridge & prevent us from getting a pattern that's too dry & suppressed, while the intense west-based -NAO will keep the SE ridge suppressed enough that the storm track doesn't go too far north. The dry suppression that often comes w/ +PNA (except for the coastal SE US) is probably a good reason why I saw more winter storms cases here in NC when the -PNA coupled to -NAO/-AO/-EPO vs +PNA.

Plus the -PNA allows for a greater connection to the Pacific and more numerous chances for shortwaves to move across the US.

The N America continent is literally poverty. We can't make any cold air of our own and have to steal from Eurasia every time instead.
Looks like the storm track remains generally north of the area after the good pattern sets in. Not really a fan of that.

Fwiw, here's a composite of Januarys w/ -AO/-NAO/-PNA/-EPO.
Even though it's super early in the record, Jan 1929 might be the best match of the bunch & it was a complete dud snow-wise here in NC even for the mtns, only a few flurries fell at the end of the month in the far N piedmont.
I guess moral of the story is even w/ an amazing pattern like this snow is still far from guaranteed. Still have to get lucky synoptically

The storm track loves to go up into the upper midwest in -AO/-NAO/-PNA Januarys. Precip is pretty much average if not slightly above here though. I'd take it

So what you are saying is that Dubuque may get a lot more snow ?
Can’t help but notice that the storm that caused the 1982 Atlanta Snowjam happened in this set up

Didn’t even realize today was the anniversary. This was a significant storm for western and central NC too. The Charlotte area got 4-8” and parts of the foothills had up to a foot.
Can you post a 500 mb map of this member, please? Would like to see it.

Is the southern slider still on the models or is it gone now and what about the long range storm that’s out there is it still there as well

We'll see when the 0z runs come out
Suppressed slider with very little precip just before hour 150, and then a some cutters/northern sliders through the balance of the run.
Good pattern? Per Bam Weather AN from week two through Fab Feb! #wintercancel lol
