Thanks, Jay!! Trying my best to deliver the goods! Haha

My idea has been that once we transition during Week 2 of January, I think that we pretty much run the table with a colder/snowier regime overall (limited warmups) through most of March before it breaks down. So far, I see no reason to stray from the ideas that brought me to that opinion, as things are proceeding according to plan.

"Build it ...and Cold n Snow ...wil come"
Or CP and Snow will come !!!!
All great information.
And I am harping on my call from mid month if not earlier that we see a NESIS thatb2nd orb3rdbweek of Jan to kick the winters arse!!

I’ve ignored it until now because it has a bias of being overly ambitious with propagating the MJO too quickly and too strongly. It always shows an amplified full rotation through the phases. Up until now, I knew that would not be the case based on the forcing mechanisms, so I didn’t pay attention. However, now that those forcing mechanisms are different, I think it has the best representation of the MJO progression, and the other models are steadily correcting towards it.

Very good question Irish. That’s less than a week away, so it would usually be highly discussed at this point. But of course, Monday has everyone’s attention at the moment.

My TWC app shows 1-3” for both Thurs night and Friday morning. In my world, that’s a perfect indication that we’re in good shape this far out. The latest GFS shows a range of 5-9” for our board. Someone here mentioned earlier that r/s lines and snowfall projections are a bit premature. Probably bc what happens Monday will clear up the picture a good deal.

So, in general, I’d say the threat appears to be alive and well. Hope that helps!

Think theres a signal for my and mugsy’s 13th-16th period??

What Snowman said haha the 1/7 threat is just that; a legitimate threat. I’m sure it will get its own thread before too long, but the focus of most is on what’s front and center right now

As much as I want snow friday and sat couldnt be worse timing, due to covid we missed seeing my family where many of my daughters gifts are and we are supposed to visit them saturday in CT, now I am a really good driver in the snow but it is the others i worry about and if we do not make it my daughter and us will be really upset. So lets make it on the 7th and clear up for morning of 8th would be perfect : ) Got it rb? Make it happen lol

Mt Holly's latest thoughts on Thursday/Friday.

The most impactful system of interest in the medium range looks to affect the region Thursday night into Friday. The deterministic solutions all feature a digging trough into the Midwest Thursday
night, becoming negatively tilted by Friday, with a developing surface low moving through the Appalachians into the Mid-Atlantic. The individual models appear to be exhibiting some typical biases,
with the GFS the most progressive and suppressed and the ECMWF farther northwest and a little slower to intensify. The CMC is the middle-ground solution (though stronger, and also by far the most
problematic for our CWA, with warning-level snows projected in much of the region). Notably, model variability is sufficiently high and run-to-run continuity is sufficiently poor to point out that this
event is by no means a slam dunk for our area...the GFS and ECMWF would indicate two failure modes for most of our area, for example.
However, pattern recognition suggests this is a setup favorable for impactful snow somewhere in the Mid-Atlantic and Northeast, and the tendency of the digging trough to become negatively-tilted would
suggest to me that farther northwest solutions would be favored (unlike the GFS trend, e.g.). Will definitely need to keep an eye on this system, with plenty of time to sift out the noise from the real
model trends.

For reference, here is the Canadian 12z:



That would certainly for make for a great for week for the whole board!

This may be banter worthy, but here’s tonight’s 00z EURO Control run:



This is its rendition of the 13th-16th potential (minus about 8 inches on average for everybody, since it also includes today’s and Friday’s events). However, even though the snowfall maps aren’t showing it, the sea level pressure maps across the ensembles (GEFS, GEPS and EPS all have a similar signature):






And their H5 depictions support it BIGLY. Today is the hors d’oeuvres, Friday could be the appetizer, and the 13th-16th threat will be the main course

Trust the process folks.

I've been discussing it in the January discussions channel. It's the most legit threat for the I-95/and NW that we've had all season. It depends on where baroclinic zone sets up as to who gets what, but I like the H5 look and the consensus among the ensembles.

Don’t be surprised if we see a pseudo -NAO during this period too. A lot of people are going to say “look at Greenland”, and “look at the charts”, but just because the atmosphere doesn’t project well onto our subjective diagrams, doesn’t mean that it won’t behave in a similar manner even though it has a non-textbook appearance. If this occurs, then it only adds to the potential. If I don’t go up north at the end of this week, then I’ll put out a video explaining what I’ve been seeing for the last several days that has me so excited.

There also might be a threat of a big storm mid month but that's too far out to talk about it..

That’s the one mugsy and I have been barking at for almost a week now (though the foundation was laid a long time before that). Now that the models are finally seeing the proper pattern evolution, they will start (and have already started) to pick up on the actual storm threat itself.
