EPS continues to get snowier for us. Man, just have one of these threats go right.

This year you want to see the heart of that map going through mass and the southern envelope well into southern NJ. Unfortunately  we haven’t seen that all winter and depictions like this end up a bullseye over Quebec.

the EPS still likes early next week for a storm, as there's a vigorous S/W ejecting out of the Plains and a strong 50/50 in place. if there is enough confluence, then there can be a front-end thump or even a coastal solution like that the OP showed... certainly possible with a 50/50 like that. worth keeping an eye on

obviously, we want to see the GFS / CMC get on board, but that will be a matter of which model is correctly handling the -NAO development. no real way to know right now

The euro used to be the king of handling -nao’s properly but I don’t know if we have anything recent to judge it on.

Huh? You haven't seen this depiction all winter. You just spout negatively for negative sake.

Thing is, we haven't seen this depiction all winter...it's been like 100 miles north of this with the best over Canada border region usually. So even if this is too far south, it's going to bode well for a large part of NNE/CNE.

It’s also the only model remotely showing that. Don’t take the cheese 

The Euro is the best model we have and it’s not clown range. Even a blend of the Euro and Gfs would be good, something like the Canadian for example. Yes it’s not as good as the Euro but it still gives us a plowable snow.

While we will have a strong -NAO at this time, I believe there's a high risk that this one, ironically, hooks up with the SE ridge, because of the overwhelming pacific. 

It's not apparent at all at H5; H5 looks generally good. But the warm 850 temps and surface flag high chance of ptype issues. The highest probs is a decent track, but "no cold air". This looks similar to the recurring issue we have had in the recent past, and it's a much different look than this week, with cold anomalies throughout the eastern CONUS and SE Canada.

The GGEM is hugely more in favor of the GFS overall... 

From this particular point in time and range, it's 2 against 1

I get the argument against it...what I have zero use for is the contingent of posters (obviously not you) that are just mentally on auto pilot and bring nothing to the table, aside from a few snide remarks in the direction of anyone venturing to entertain the notion of major snow.

That gets older than this winter's pattern.

Yes, even on the EURO, its marginally cold enough until after the storm passes.

Yes, another strike against this evolution is we once again are dealing with a marginal airmass.

Seems to be a common theme this winter

Don't let facts get in the way of a nice persistence rant....

The pattern has definitely changed a bit, no denying that. We are still dealing with a lot of the same issues though as we look at longer range guidance. 
 

Lack of cold air, systems cutting west/over us, poorly timed transient highs or 50/50s.

The pattern isn’t the same, but the end result might be, for a lot of the same reasons we’ve been dealing with since December.

I do like how you consider all of the possible outcomes...

The cold air thing is a valid point, but it is important to consider that if the storm is strong enough it can make its own cold.

The euro verbatim was a good airmass inland and quickly raced to the coast to dump over a foot. 

Antecedent airmass is actually decent out ahead of the storm....it's just a question of the block being good enough to force redevelopment soon enough to hold in that airmass....if not, then we erode it and get a pseudo-cutter, but on the Euro, it redevelops and we're good.

Yes, fair statement. But there is also a legit shot one of these systems pans out if the block situates favorably.
