Well this is an unfortunate turn...it's always fun to break records tho in both directions. There is run-of-the-mill waste warmth and then there is your turkey leg warmth.

well, if you go to the next day, 240 hours, you do finally see a 5H low south of the Aleutians, which is where we want it, along with some ridging in Greenland, so patience

Fast retrograde, I don't buy longer leads even on the Euro. Yeah, I want a furnace....who wants their forecast to be wrong? If snow comes, i'll take it all in tho with love. 

 

With an +AO like that, you won't be able to get cold air delivery south of 45N. The lack of -NAO is just more fuel for the fire.

12z EPS flipped back to bn Tday. All is right with the world. Last night was a blip until it isn't 

Weeklies have hinted at a bit of a cooldown near or after tgiving for a few days to a week or so as you probably know. Of course then it goes back to torch.  Dec could be silly torch.

the storm in December will need to manufacture its own cold air

Yea, although still over 3 weeks away, if the current persistent pattern occupies part of Dec then it won't be a fun month for us. Jury is out whether the current persistence in the high latitudes is something that is "better to get out of the way" now or the beginning of winter is showing some cards already.

Interesting 12z euro run. Nice squeeze from both sides over the pole. Probably a blip but the evolution starts well before d10 so there's at least that. The strat plots finally show a nice elongation of the PV as well (most noticeable at 30 & 50hpa). It's looked like a perfect concentric circle target at all levels for a few weeks now. Nice to see things shake up a little on the models.

EPS really bumped up the + height anomaly centered just off the BC coast d10-15. Pretty good look for a normal to BN holiday. 

 

On a weenie note...a handful of ens members drop some snow during the d10-15 range...lol

12z GEFS showed some evolution to the pattern as well with some ridging out west and Aleutian troughing.  But way out there still. 

 

I think most of December is a punt.  Hopefully we can wedge in a nice pattern for a few days somewhere and sneak in something.

Euro ensembles have gotten pretty bullish on the strong ridge in the GOA into NW canada D10-15. This should build some cold in Canada that dumps into the conus. Looks like the focus for the cold is west of the MS river but we'll get our shots in the mix. 

 

GEFS diverges a bit from the EPS in the high latitudes during d10-15. GEFS moves the vortex back over the pole with lowest height anoms over AK but the EPS puts the squeeze on with the lowest height anoms in eastern Siberia with more of a ridge look over AK.

 

Overall it's kinda of a strange pattern considering we're in a strong Nino. Aleutian low has yet show any signs of taking shape and having a strong ridge in the GOA region is definitely not common in strong +enso. CPC analogs showing a handful of weaker ones though (04,94, 86, and 51).

 

The only thing I'm really hoping for going into Dec is not having a strong/consolidated vortex over the pole region. EPS and euro op are squeezing things down the line but who knows.   Weeklies last night are still warmish and boring for the first 2 weeks of Dec.

Even the OP EURO 00z was pretty sweet in the LR. Some positive signs.
