East Coast Winter Storm (ECWS) potential Jan 21-22 was about 150 miles too far southeast. Is it ATL to New England, or just a portion of or does it yet fritter to a weaker 23-24 event only NJ/PA northward?

Whoever is not worried about the GFS not being close does not like snow IMO.  I take the other side - I'm definitely concerned. And we don't really have so much time to shift this. By hour 60 it's clear the trof has no chance. Really even by hour 48 it's pretty much toast. So the next few runs of the GFS better start showing some changes or we're into longshot territory.

That said, this run was a tiny little bit better than 12z.

Disagree. The GFS is not close. And it's not a track problem. It's a trof problem. If the GFS is close to being correct, we have no east coast storm.

Why would we trust the GFS setup over the Euro at this juncture though?   Also the GFS does show a potential east coast storm it's just a day later.

Also have to think about the pattern. Right now I'd take my chances with amped over surpressed. Normally I wouldn't say that anywhere near the coast but this cold air in the next few weeks is strong.  Of course it depends a bit on Location, overamped got me an inch yesterday the ACY blizzard I didn't see a flake. However I realize for places like South Shore of LI and NJ coast it was the opposite.  

I'm a snow purist so I'd rather see no snow at all over seeing snow washed away by rain.  It's just a thing I've always had since the 80s.

It's not GFS vs Euro. It's snowstorm vs no snowstorm (for us).

1) The no storm idea has support from the CMC, UK, and ICON. And maybe the NAM extrapolated (tenuous).

2) The EC barely gets it done. Even with a very sharp and amplified trof, the heavy QPF is confined to I-95 east.

3) Snowstorms usually don't work out; just basic climo statistics. If something can go wrong, it usually will. There are several potential problems visible on the EC H5 chart that could easily mess this up. We need several key features to cooperate, none of which have support from other guidance.

I think the EC is the best global domain meteorological model in the world. I'd still vote no snowstorm right now if I had to. 

I'd agree at this point I'd lean no snowstorm as well. If Euro holds it's solution at 0Z and/or any other models come on board at 0Z my confidence would go up a lot though.

Getting the feeling this may be a NYC, south and east event. You don’t have to worry about this one amping into an inland runner, I think the threat is a miss east/south not hugger or runner. Totally different setup from this past one 

You said every storm trended NW this winter but suddenly this one can't? 

There's every reason for this to trend west actually. In fact eventually people may panic about it trending too far west. 

Gfs is moving towards euro btw, higher heights off the coast.

I think your view might be a bit biased because of your location.  On Long Island the chances are significantly higher.

When I was young I used to agree. Now Im looking for excitement I guess so I'd take snow to rain over cold and frigid.   

Oh I hate cold and dry too (I assume thats what you meant.)  I just meant let's say if we get 2-4 inches here and 50 miles south of here gets a foot.  I wouldn't be extremely happy about it, but it's better than getting all your snow washed away by rain.  The ACY snowstorm wasn't something I liked either, because we didn't get diddly from that, very much like the Feb 1989 event.

Yes definitely agree with that I'd rather have 2-4 of all snow than 2-4 washed away by rain but i'd probably rather have 2-4 washed away by rain then all dry and cold unless there already is a snowpack in place.

Lee Goldberg already has the snow icon up for Saturday.  He said that we'll either get a snowstorm or just miss it, but his confidence is high enough for snowstorm .

You're in a different boat entirely, you're on the east end lol.

 

Yes, but the reason the euro was a hit was because it showed a clean phase. Nothing else is doing that yet. So they miss. I believe that's what he's getting at. It's not a straightforward process of the low being west or east. Hence my agreement with him. Hopefully the euro has the right idea here.

A few EC individual members look too wrapped up, just like this past storm. And a bunch look like the GFS. Let's not completely assume any options are off the table.

If we do get the shift we're looking for towards the EC, then inland solutions definitely could become a concern. But for now we need to see the GFS camp shift towards the EC. Then we'll worry about ptype if we have to.
