It's a shocking turn of events for sure but I just can't get excited for this yet. This is just one euro run. Please keep in mind it has no support and we can just as equally be fringed with lighter snows while SNE gets theirs.

With all due respect, it has plenty of support. Granted it's not the exact same support on the other models, but this model is not on an island. Also, it's the second run its showing a strong storm, yes not for the whole tri state but it's a second very strong run.

While this definitely has gotten way more interesting, I'm not ready to jump on the insane train for Monday until we have more models join the EURO. It wasn't too long ago that we were drooling over a 969mb bomb over the benchmark, so it's probably best to err on the side of caution for another day.

I would think that if things stay on track that Winter Storm/Blizzard Watches would be issued either tomorrow morning or afternoon by the NWS.

 

Watches probably tomorrow afternoon.  Blizzard warnings require a lot of model agreement and criteria in order to issue, so there would need to be some consistency and probably those would go up Monday during the day.

Anyone on the forum work for Sanitation or OEM and know how long it takes to gear the City up for this type of event?

Working hand in hand with Suffolk County Oem most of the time,; we won't have the time to gear up completely for this storm. But, in Suffolk, if they pulled out all the stops by tomorrow afternoon, we could be somewhat prepapared.

Wow, that would be one insane easterly jet coming in from the Atlantic=tons of moisture transport for tremendous snow banding. 2/8/13 had many of the same features, which drove the superband over Suffolk County and CT. Looking at surface winds, they should also easily gust to 50-60 mph if not higher along the coast. 

 

Hopefully tonight's runs solidify the trending from 12z.

If 0z models show this, blizzard watches will almost surely be hoisted by midnight.

100% agree - best to take the cautious approach ATM  - either way, that will be a run Ill always remember - if something like that were to verify - it would be a storm of a lifetime - cant let myself get hooked yet

What's this talk by the WPC on convective feedback on the EURO resulting in this solution? Any mets care to chime in on that?

Very interesting...don't think they like the ECMWF.

THERE IS UNCERTAINTY WITH THIS SYSTEM, WITH SOME OF IT INTRODUCED

I would like to hear what DT has to say about this.

The atmosphere has been doing some really wild stuff in recent years.

The coldest 5 day period is in front of us  Early Jan we had a week of - 12 , think we have a chance next week to beat it .

I have been saying we are going to beat the 4 we saw in early Jan , and Feb may just turn out to be BRUTAL .

 

I  love the Euro and I live and die by it , but I just want to see it replicate this 1 more x , these jump scenarios happen .

They get going late and smash SNE .  The misses are always on my mind . Great run if it verified would be one we will talk about over and over .

The Euro burned me at 12z Wed when I bought the CCB over the island , so I am cautious .

Quick notes of caution... This system has evolved in the models to be a very large, and powerfully dynamic system. So much so that it will have "it's own" internal idiosyncrasies that will inevitably emerge, and be poorly modeled when they do. Such nuances can and do have an impact on sensible as well as more meaningful strike events...

Having said that, the Euro actually is processing details that may not even exist ... or, perhaps they will; but the point being, with immense systems of certain power comes along equally daunting complexities, and the Euro's creating a wave out over the Gulf Stream may have a couple considerations....

One, it may rob some moisture from wrapping W into the CCB band. It may also cut off some of the WCB ingest into the core deep layer mechanics. The 2ndary result of that (if in deed it is an error) is that the system may actually not be currently modeled deep or prolific enough in that particular guidance source...

That said, there is soooo much incredible dynamics with this thing, satellite vortices (to borrow an expression from our Plains brethren) almost seem necessary. I could almost even envision a wave forming over the Bahamas after the cold front clears Florida."
