ok..here's our next system potential to follow...still a bit out... just keep an eye on the ensembles until we're around 4-5 days

We shall see but interesting how it was cutter city two days ago and last night 18Z runs it started to shift these SE on BOTH ENS and OP runs. Only 6 days away LOL!

Up close views:






Smoke City for LI! IF IT VERIFIES!!

Endless enthusiasm…..like a kid on Christmas, and I love it haha

Unfort until proven otherwise I agreee with Heehaw, Matty Ice, and Ray ray. Not too much to add. There just isnt a mechanism to prevent this thing from cutting IMO. The PAC side of things is just awful

It’s all coming together quite nicely. Things are on track…..





I like a blend of these two; GEFS amplitude, GEFS/EC ENSEMBLE blend of phase.

TRUST THE PROCESS.

We suffer and torch now, reap the reward later.

MJO into seven is starting to look like this...Cut inside..nope going outside into 7, NOPE!! cutting back inside into 6!!!

The only thing that seems clear to me is we haven't hit maximum +AO state yet.  It's projected to go +3 sigma in a few days which concerns me the PV may be stubborn.

I’m not looking at the near-term effects with this. My opinion for the last week or so has been that December and the front half of January is wasted, and I think so far, that’s being proven to have merit. With the coupling between the Stratospheric PV and Tropospheric PV constructively interfering with the coupling between tropical modes, it’s pretty clear to me that any hopes for winter in the near term are false.

I’m not playing that game. I’m playing the long-range game here, and looking at what the extended impacts will be of the pattern that we are experiencing now and during the next several weeks. So, regardless of the immediate MJO phase and amplitude, I don’t think it’s going to matter. I think warmth and cutters run the table through mid-January, on the whole. However, the atmospheric process that should evolve over the next six weeks, ESPECIALLY if we can get the higher amplitude MJO response in phases 6 and 7 (which, as I stated in my original discussion, should be the end result, and I think you’re seeing the modeling adjust in that direction. Slow rotation through those phases at notably increased amplitude), it will largely help our cause down the road. And that’s where my bets are placed.

   we will probably have a warm up after December 10th Fast pac flow should keep temps up-and-down Not a complete torch.  Lastly it won't take much to shuffle up the pattern with those factors mentioned above close by. let's get the MJO into phase 7 and see what happens from there

I have to respectfully disagree with your statements regarding “the warmup”. We start getting out our our current colder stretch in a couple days and get into a typical “back and forth” regime in a couple days. This then biases warm thereafter. So really, we are in the dying days of our colder stretch already.

algae888 wrote:The system on the 8th has my interest We'll have a very cold air mass in place.  Not buying some of the amped up operational model solutions not with a very fast pac flow. we need that high pressure to sit over New England not off the East coast to get some overrunning snows

I wouldn’t buy into this at all, honestly. It’s a classic case of the modeling under representing the warm air advection, and you already acknowledged the culprit - the retreat of the high pressure (and therefore, your cold air source) off the coast opens the flood gates for the warmth to surge (among other hemispheric properties).

The match has been lit. How long and how strong can we go? I still like the amplitude of the GEFS, and a blend of the GEFS and EC for phase evolution:







Let’s watch it burn and see what happens. I like our prospects, increasingly from day to day, I might add. And, the long-range GEFS are beginning to show signs of EXACTLY what I’m looking for in the Strat. And with the magnitude that they are showing it at a two-week lead, it’s impressive. I know it’s the GFS at extended range, but when it fits my preconceived ideas, I start paying attention. I’m trying to claw around for additional details, but it’s tough lol so sit tight folks, and TRUST THE PROCESS.

Additionally, some of you are going to see “MJO Phase 7 at amplitude in December is cold”. Yes, at face value. But the problem is it’s enhancing the La Niña signal in the background state; it’s not acting on a tropically “neutral” playing field. This means that it will act very differently than it otherwise would. I believe a strong La Niña response (which is about what you’ll have if you combine the background La Niña forcing with the MJO pulse) is an all-out torch for us, similar to strong El Niño, with an enhanced Southeast ridge, and that should be our result here during the next several weeks. But somebody please check my memory on this and correct me if I’m wrong.

Note the increase in reds over Eastern Asia (warming) combined with the expansion of the height field in that area (warming, slowing of the wind field, respectively). This is at the heart of the Stratosphere, that would be the start of a true Stratospheric warming event. The signal at this lead is impressive, especially for an ensemble. Let’s see if it keeps showing it, AND if it keeps the progression…



My gif isn’t working again

Yeah, I think we are out of the game until mid-January, but by Week 3 of January we start making up for lost time. To clarify, I’m NOT happy that we are losing the opening month (plus) of my favorite season, but unlike some other years, I don’t see any reason to jump off the cliff. Right now I fully believe that we are just going to have to be patient, and in time, we will be rewarded pretty handsomely. As I said, once we flip, which I think will be during Week 2 of January, I think we flip hard and have an old-fashioned winter from Week 3 of January through most, if not even all of March. In looking at how I expect this winter to play out regarding the overall evolution of winter, I like ‘17-‘18 as an analog, but we will be about a month to six weeks ahead of that pace. Granted, I’ve not compared ENSO or QBO states, SST configurations, or things like that, and that may be my downfall. But conceptually, I like a similar evolution to how that winter played out, just on an earlier timeline relative to the seasonality.
