On most of the models it is not living up to it's potential YET ! I think many of us get ahead of ourselves thinking it's much later in the month -- it's only January 11 !!! So far this year is playing out just like last year on January 11 - there wasn't much hope and we all know the rest of the story of what happened the rest of last winter. As for the GFS model - shouldn't consider it past 84 hours IMO.

I am not giving up like last winter though like some people already have on the internet :popcorn:

Didnt the pattern just change? How can it not live up to potential when it hasnt even happened yet. People have to relax in here.

I was pissed off about the models last night. I am fine now. Patience is key, just like last year. Many mets think a ssw is going to happen at the end of this month to disrupt the PV . That would make February and March cold and snowy.

This could be the worst producing epic pattern of all time. Up to an inch from a clipper Tuesday night might just be the highlight of the epic pattern, the jury is still out on whether or not the January 17-18 system will produce for us. However, with a primary low in the Great Lakes, it is going to be darn near impossible unless a secondary can develop around OBX and intensify rapidly. Models are not showing this scenario at this juncture. Not sure who it was that claimed the Jan 18 system was well ots, but since the surface low (primary) is clearly well West of the area, Im not sure exactly how one can claim victory at this being ots....unless u were referring to the weak surface reflection along the stationary/warm front that is progged to be off the coast? Which is something different....apples and oranges.

Well considering "TODAY" was the start of the new pattern regime I hope you didn't expect to wake up to a foot of snow.

Secondly it's been said here 100x even great patterns don't have to produce.

You will have a trough in the SE and ridging over the top over the next 2 weeks . It will only produce If you can slow the PAC down for more than 2 days , but it doesn't have too.

So better to take a wait and see approach.

Cold doesn't equal snow and people should not look at systems outside 5 days or you will just get disappointed. The primary is going to the lakes and not OTS.

Amazing a lakes cutter with blocking...just ouch

The blocking doesn't prevent the cutter, it just forces the redevelopment, which does occur, but it's not lining up for us just yet. Weenies are jumping all over American Weather. Just let things play out. It's a highly complex setup with multiple shortwaves.

We won't know until Thursday when the clipper clears the area and the shortwave comes onshore. Even then, the setup is highly complex and the outcome will still differ. People need to learn to not take OP runs past day 3.

2 things. Here are the temperature anomalies January 1st through January 10th, this speaks for itself, Philly is almost +4 for the month as one example: https://mobile.twitter.com/antmasiello/status/686538484098674688/photos Second, I tried telling you guys that the roaring, roided up STJ was going to be a serious problem and I was attacked. Look at what happened to next weekend's snow threat thanks to the raging STJ (super El Niño) crashing into the +PNA and breaking it down and causing downstream pressure rises on the east coast. And low and behold the models have shifted to a cutter. Total southern stream domination thanks to the Nino. Also, I warned that the calls for "rapid Nino weakening" and a "east to west" collapse were also likely wrong and what happened? The weakening has been very slow to say the least. We are at mid January, regions 3.4 and 4 are slowly cooling from upwelling ongoing there and regions 1+2 and 3 have warmed. So what you have taking shape is a west to east not east to west collapse. I mentioned it before but the models have a strong MJO wave going into phase 2 again and the associated IO convection fires at the end of this month and going into February. The AO, due to the move in forcing, goes right back up to neutral/positive because it was all tropospherically driven and we still have yet to see a true SSW despite the calls that it's coming since November. With nothing stratospherically to drive the NAO and AO negative, once the forcing goes back into the IO, they go positive and it gets mild once again. Also, expect the EPO to go very positive once again. I'll admit as I did earlier, my call for a cold and snowy February is probably in real serious peril. I'll admit it now because I see what is coming...

Why are people saying that it's going to be warm because of phase 2? Phase 2 is a cold phase during the winter, not a warm phase.

The lagged MJO composite anomalies for January-March build ridging in the East. As a result, the typical evolution features cold giving way to milder anomalies. Personally, I think the blocking will generally hold and we'll wind up with a colder than normal anomaly following mid-month +/- a few days through the end of January.

maybe it was never an epic pattern to begin with

-7SD AO

-4SD NAO forecast at the time .Don wrote a great piece at the time that showed how those anomalies compared to other periods with the same set up .

It has backed off , but at the time anomalous blocking had shown up on the ensembles for several days.

It's still a good pattern and it's there In the means over the next 10 to 15 days.

Everyone here knows there are no guarantees.

Surprised we are at +4 for Jan....seems like it had been cold outside of yesterday

We are not. KNYC is 3.4 after 1 day put 1.8 on.

Always double check his work.

Will back back BN in a week

GFS -AO -NAO -EPO heads to N back to -

For rjay 1.2 cooled .9 over the last 2 weeks added only .2 this week .

This is collapsing east to west /supported by the guidance and the verifications over the last 3 weeks.
