There won't be any problems with the dry slot or mix for us. MAYBE for out by Montauk if the west trend really does continue. Our issue would be subsidence zones between bands which can't be forecast now. I can definitely understand Forky beginning to get excited. Boxing Day 2010 was supposed to be a LI focused storm too and it buried E NJ. I don't see how this has to stop going west here.

Yeah if that happens we won't have to worry at all from the city on east about picking up totals over and possibly well over a foot. That's a thing of beauty.

Metsfan's right. Miller A's (which this storm is more of than miller B ) aren't the GFS strong suit. It seems to do better with storms dominated by the northern stream which the Euro can struggle with. And GFS was very close to being considerably better. It had the stupid double low which stole a little and dragged the storm east.

Jeez is anyone shocked? What a shame that after this big upgrade it still sucks royally on pinning down these coastal storms more than 48hrs out.

That's fine, I'm not concerned about it. When has it not caught up at the very end with these? As long as it's moving in the right direction it's fine by me.

Lots of us were saying what could happen with a slightly earlier closing off of the low. This could and probably will make shifts but there's nothing to really stop it from coming west at least another 30-40 miles. And it's not a given that it'll trend back east at the last minute. 1/4/18 came west until the very end, I think 12/19/09 trended NW until the end, so did Boxing Day 2010. Sure some do tick back east but it's not a rule.

I lost my dad just over 2 years ago when I was 33 and I still think about him every day and probably will for the rest of my life. He wasn't too much into my weather hobby; my mom was always a little annoyed at it-"why do you care so much about snow?". But he would at least have conversations with me about things like this.

With this storm and the dynamics/moisture at play, QPF probably isn't overdone. But again the Kuchera maps especially in the worst of it with blizzard conditions aren't happening. I could see maybe 12-1 ratios there. Winds will break the flakes apart and hurt ratios. The best ratios will be inland where winds will be reduced and there can be more piling up (but there will be less QPF).

I’ll believe something like that when I see it but that Nam run would be how it happens.

I’m so sorry for your loss. Hopefully this upcoming storm can be something of a consolation for you. Here’s to your dad!!

O Lord above, only one thing I pray unto you this night. THAT THE NAM FINALLY GOT A CLUE!!!

Wow. Essentially draw a line south from Nantucket. Each of the solutions west of there when nearest us would probably be big for the city on east. Huge chunk of members there.

That was a very encouraging run even back into NYC. I wouldn't go crazy over the precip output although it still shows a borderline MECS in the city verbatim. And yes it can still keep ticking west if the upper low closes off a few hours sooner as others pointed out. Trend is undeniable for the Euro since 6z to bring the heavy snow west. Interested to see the EPS and how many monsters it has that can bring crippling amounts into the city. Those are a possibility. Not high possibility but can't be ignored. But wow, central and eastern Suffolk are quite possibly in for an all out blizzard on Saturday. 2 foot amounts will be common there if the banding sets up like the Euro showed here. Could be 2/8/13-like where that happens, Euro showed roughly along Rt 112 over to the William Floyd for the death band. Latest NAM was a little east of there. And NW of NYC should be encouraged too at the heavier amounts inching west. Could probably be a warning event on this run out to western NJ, and there ratios will help. Again I wouldn't go higher than 12 or 13:1 ratios near the coast because of the strong winds. But the 1.2" liquid it shows on the Nassau/Suffolk border would still be 14-15". Can't really talk all out blizzard for near NYC yet but trust me it isn't too far away from that with some minor added improvement.

Probably a good call at this point.

That would be awesome if we get the closed low just a little NW of there. I couldn't care less what crappy GFS surface reflection would be.

RGEM looks very similar to the last 3 runs.

Maybe. Hopefully we can get this tucked a little further. Lots of possibilities still. A GFS dud can’t be written off either given the number of EPS members fairly similar.

Based on the 700mb features it makes sense to me where the heavy snow bands would be located at least. It would start over central to eastern Suffolk and then obliterate their way up into E CT into MA. Good snow would make it back to NYC but not the death band stuff. It looks like Juno 2015 pretty much. 1/4/18 had a similar track/upper air features and may have a similar evolution in the end. BTW, don't look at the 3k NAM. Total dud pretty much. Incredible how fickle this all is. Fingers crossed that these tucked in, wrapped up models win out.

The death 3-5"/hr band on that would likely be around the William Floyd Parkway. It's usually a little west of where that crazy frontogenesis line is. For the city I'd want that about 50 mi west of there. Also that'd be a tremendous moist feed. 90+kt S and E winds coming in from off the ocean at this level. That would certainly be a burial where that band sets up.

Looks like a nice improvement from 12z. If we can just keep that low west of the B/M a bit as it bombs out.

In any situation when I see a 500mb chart like that I'd think 90% of us are about to be buried. Nice backing of the flow already as trough is about to go negative.

Where you are, definitely. 12"+ is probably a lock and likely 15"+.

It doesn’t “push it away” but if it gets out of hand it flattens the heights out ahead of it somewhat which we don’t want. And also…. It’s the Nam.

The bickering is so ridiculous. Take it to PM or banter or better yet nowhere and grow the F up. In the meantime when I see those posts they’re getting deleted.

Yep, crazy the spread in EPS outcomes this close in. A few horrible GFS like ones there but hopefully it’s just the model trying to get a clue given the dynamic setup. I tend to think we’re okay east of the city and golden for places like the Forks but plenty of watching left.
