The rest of our lives 

We actually have some pretty big pressure hitting the coast of Alaska today, and it's so warm out.. feels like 50. If the -PNA/+NAO that these LR models are showing verifies it will be 60s/70s

^look how this is kind of a 180*/from today, and it's still so warm out. Pressure breaching the N. Pacific is definitely a staple of this time. 

(I still think there is a +PNA signal 2nd week of February, will be interesting to see how this evolves.)

On the above gif, It appears that the High comes in to late with a low pushing through the north of New England. Wouldn't the Low be problematic?

Regardless of what precip field that's showing, verbatim that's high elevation mountains heavy snow NC and VA . Thickness appears to be shown as ab out 543 in those area's. As long as 850 is 0 to -2T C. . 

     Of course, does most of us no good. Hopefully, more cold will be injected than modeled.

Wetter than average/-NAO December's evolves into +NAO February's

Drier than average/+NAO December's evolves into -NAO February's

75 years of basis.. pretty cool correlation there. The Feb NAO signal> Dec NAO(pick and choose)

*wetter/drier than average across the US

 

Strong -PNA December's = -PNA/+NAO February's at 0.68 correlation

Strong +PNA December's = +PNA/-NAO February's at 0.70 correlation

Yeah, many have punted mid Feb as very mild due to lrg and MJO warm phase forecast by most guidance. Hopefully, MJO avoids those phases then . Would be our luck to get a + PNA then and the MJO foul us up then.

     It's just that type Winter.

Warm neutral isn't gonna do much good...If we're already trending warmer, doesn't that make a case for a more established niño next winter?

Warm neutral is prob better than nina....

Yeah but if neutrals are no longer working (the last two were awful), and a very weak niño a la 2018-19 doesn't work...we better hope for a legit one!

Too small a sample to draw conclusions but the last one was 2020 and the last 4 were all below below normal!

These 3 panels illustrate how problematic next week is. Flat, fast flow with weak strung out vorticity in the "southern stream", modified dry cold, and suppressed moisture feed. Need a robust shortwave to bring moisture northward, and even then the 'true cold' is too far north, associated with the W-E oriented TPV.
