The only good news is the NAM is normally very amped and warm at the end of its runs with any sort of deep low coming up the coast or the OH Valley, this run is surprisingly cold and less amped than you'd normally expect considering where the Euro/GFS are...normally the NAM would be in Chicago given those models.....yeah I am reaching a bit..

You r right. The energy hasn't closed off by the end of the run, confluence is strengthening.

NAM loves to play catch up. Esp when it's more than 48-60 hrs out. It already jumped NW from it's 12z run for the same time frames.

Would likely be a front end dump at the very least. Grasping as straws here but this is a slightly good sign. However if the gfs and euro hold serve my towel will be thrown

Well at least someone further west will benefit, good news for them, congrats Ohio, Western PA, Western NY state. As far as a new year's storm goes, I'm just gonna ignore it unless there's a real threat inside 72 hrs.

I have forecast interests for Detroit and don't really want the hassle. If we aren't getting snow my preference would be something just far enough east so they miss it

We need to give it another couple more days. If no good model runs by tomorrow night, it probably won't be good. Not sure why the transfer isn't happening earlier.

Because there's a lack of a block and a lack of confluence. The low doesnt hit a brick wall to its north to cause it to transfer like it did in earlier runs.

Time to close the book on this one.

I think there is still chance for a front-end dump for a lot of us on the board. An all-snow solution doesn't look likely, but it never was.

Definitely disappointing though to see XMAS turn into just light flurries/drizzle, and then this turn into a lakes cutter...just when we thought we were done with lakes cutters. The only good news is it could set the stage for the big 12/29 threat.

It's not a lakes cutter, this is a super rare apps runner. I think it will be more west when all is said and done, but this isn't gong to verify as the GFS has it. Gonna be rainy in the i95 area.

The Canadian and even the NAM tonight were showing redevelopment, so I think there is chance this evolves differently than the GFS. For snow at least at the beginning and end.

A bit surprised by the lack of any CAD signature given there's a decent high in SE Canada although since it's one main storm and not a secondary type deal, it makes sense.

I haven't seen this type of track recently, it's sort of an Apps runner, probably just to the west of them. Usually it's much further west or a coastal/OTS solution. I was hoping the models would trend OTS with this one because that gives us a better shot than what the models unfold on us now. Once it's inland like shown, it almost never shift too far east.

The system crashing into the west coast is helping to pull the tof axis back in the east . As that system enters the west coast the response downstream is to buckle the jet before the trof can swing to the east coast . If you want a different east coast solution the west coast would have to help and its not .You can track the 29 th system all you want the models just lost 2 storms inside a day , one would have to be a fool to look beyond 5 days in this pattern .

Given the GFS verbatim, I would anticipate some significant icing concerns inland w/ that strong of a sfc high in SE Canada. You've got NELY ageostropic flow with the low coming up to the SW, that would be a classic interior Northeast ice event. Snow wise it's no good due to the torching in the mid levels, but we almost always see modelling underestimate sfc temps when there's a decent high in place nearby.

I'm waiting through tomorrow to write this one off for everyone. The short wave is still out in the relatively poorly sampled Pacific compared to when it gets on the West Coast about 24 hours from now. This morning's 06z GFS basically suggested an all out snowstorm just inland from NYC, so the changes in just a couple runs are fairly drastic, Additionally, given the way the Christmas wave has been handled in the shorter range, going from a potential 3-6" hit on the GFS to nothing, I think we'll be seeing some more changes here. Whether or not they're positive for us, jury's out on that one.

This was after the 18z runs yesterday...

Classic snowstorm on the GFS/DGEX... Hopefully this time it actually verifies and not one of those medium range snowstorms that end up as rain or a mix.

Yet again it's shaping up to be just that. There's still a few days left and at the very least I would expect some additional changes with the GFS given its lack of consistency with a single solution today, but I don't like the overall trends for this, especially with the GFS/GEFS, also considering changes with the PV and the blocking in Canada. By this point the most I'm hoping for with this is maybe a little front end snow/mix, otherwise I'm moving on to the 12/30 potential.
