If you're willing to buy the Day 13-15 GEFS with a healthy dose of salt, it possibly shows something positive. The high heights that are present throughout the central and eastern CONUS and Canada around Day 10 shrink and move toward northern Hudson Bay and Baffin island. This is a nice positioning for a west-based -NAO. It's a long way off and wouldn't work alone to make us flip to a frigid wintry pattern, but it's about the only positive thing I can see right now.

Euro ens show a ridge building north of HI that looks like it will try to wedge between Troughs in the GOA and Aleutians. This could be good because it could possibly take up residence in the GOA/west coast and help send the epo back negative.

A troubling trend is towards a +AO. It's not strong or anything but it's there on both the GEFS/EPS. We'll see if that actually happens before worrying much. However, it would be quite unlike 02-03 or 09-10. 94 and 06 remain plastered in CPC analogs as well. Is it a warning shot? I'm not really sure but I don't like seeing it. If the AO is + during the second half of the month then we'll have even more work to do to get into a good pattern.

It's a safe guess to say the current pac driven pattern is stable and will take time to move around. Expecting a quick flip (while possible) will cause some frustration. Where we go from there is a burning question.

The muted torch talk means nothing to me. I only care about height patterns. Even if the next couple weeks end up BN and we get some freak event, the overall setup in the NH royally sucks for snow chances and we're still going backwards instead of forwards. Until that changes I don't have much positive to say. Sure would be nice to time a flip before the holidays.

ECMF_phase_51m_full.gif

 

Thats actually worlds better than the ECMWF once showed...go check out yesterday's postings in the SNE thread though, phase 8 in El Nino Decembers is actually worse for cold and snow in the East than phase 7 is...phase 1 and 2 are best I believe.  El Nino itself just seems to trump the MJO overall in December.

I was mostly poking fun at the the possible re-emergence back into phase 4. If that were to happen with no break in the pac onslaught there will be a long line at the cliff.

No panic on my end. We get stuck in plenty of crappy patterns in the majority of our winters so it's hardly unprecedented in these parts. If we are having these same conversations in 2 weeks then we know there is trouble in paradise.

Looking at the MJO/warm ENSO/Dec composites...they all suck, phase 1 is marginal at best.  Seems like nino's are destined to suck in Dec, based on MJO.

I'd much rather have the cheeseburger.....

Agree that we still here in two weeks things may need to b re-evaluated.

Easy solution. Root for COD.

Honestly, I've never been sold that the mjo is a primary driver. It helps and hurts for sure but just looking at the phase and drawing hard conclusions is overlooking way too many other important factors. I find myself only looking at it when things suck. Like right now.

Yep!  I feel like we have been in December for 3 weeks already and it's only Dec 4th.  I hate watching these ensembles....a few more hours for the weeklies :-)

Phase 6 isn't bad, but it doesn't seem to really be doing much in the forecasted pattern.  Reemerging in Phase 4 would be no bueno. 

 

Kind of have to grasp at straws right now, but EPS/GEFS both *hint* at things transitioning very late in their runs, although 12z GEFS looks a little worse vs. 0z.  Hard to find much.  Pass the egg nog.

I wouldn't mind if December blows and we cash in with classic Nino snowstorms in JFM, just me though.

 

I have a bet with my friend up in Fairbanks on who gets more snow through DJF....Fairbanks snow in DJF only averages to about 24" or so, so all we need is a few good storms... :whistle:

Well 12z Euro is back to giving you guys a little something and back to a big one for the NE.

That's all they get?

 

I just looked it up and saw that their snowiest February was in 1966 with 43.1". BWI beat that in Feb. 2010 with around 50" if I remember correctly.

December sucks in immediate dc metro.....not sure why people care that much....It sucked in 65,77, 79, 86, 04, 06, which were all passable or good nino winters...**** - last year DCA only got 1.5" in DEC...plus Dec isn't over yet...getting a storm toward the end of the month wouldn't surprise me..I don't take December very seriously in any winter..my 10 year average is 3.5" and that includes 12/18-19/2009.....If we are going to get blocking in the means, I'd hate to waste a portion of it on early December...December 2010's mega block yielded me 2"....If we get a bad pattern January 15-Feb 20th, then I'll be pissed...now..who gives a crap...my average high is 50..I'm just going to enjoy the crisp weather...

Yeah, DJF tends to be not very snowy for them, I am hoping the El Nino pattern holds for Alaska and they get an even drier pattern in the Interior.

I've been following weather in DC for too long to melt down over December...It isn't worth it.....It's all bonus snow...even 1/1 - 1/15 usually blows..it's disconcerting, but for those of us near the cities, we have like a 5-6 week window where we get 60-70% of our average snow...December is kind of like a fall month.....At least it isn't 2006/2011 when we could comfortably cancel December on 12/1....I think 12/20-12/31 is still up in the air...

Standard 34* stuff. Column would actually support snow but as Ian said, it's a very weird evolution. Not something I'm going to try and think about until it's actually happening

I didn't look at last night's but it seems to have dropped the two lows. Now it's just one that goes SE then turns around and goes north with the second 500 wave. Pretty sure it won't happen as shown lol. Weekend looks like a cold rain tho.
