Most of the precip is over by then. Hours 69-75 is drizzle.

thats what im trying to say over and over and people don't seem to grasp it lol. west of central suffolk, this is a paste job no ifs ands or buts. It does eventually changeover to drizzle but who cares at that point

Yes, for now. But the significant NW shift keeps occuring with every cycle of model runs. When does it stop? 

The blocking is such that it won't trend much further north if at all. This run is probably too amped up as the NAM can sometimes get, but it echoes the general trend for today-toward a more amplified and wetter outcome for us. Verbatim almost everyone would be snow with the very strong lift and dynamics that would occur, and much of it at night and with a NNE wind. Eastern LI and eastern New England would probably be worse off under such an outcome because the warming at 850 and below gets quite severe there, jackpot would likely be N/C NJ. But it would be a crushing for sure.

Ok, now the NW/N trend can stop....

This NAM run is the only one we have showing this kind of epicness for us. The NW trend can stop now on the NAM but not so for the rest of the models out there. Plenty more changes still needed on the rest of the models before we can lock anything like this in. Ease your worries by leaning back on the blocking set-up that will be in place. It can only get so for N or NW.

Just to calm some nerves for the Long Island folks, the high res NAM precip type shows snow as the primary precip extending some 50 miles east out onto long Island. I wouldn't be worried unless I lived out towards Suffolk County. Temps are below freezing at all levels except the surface and it's not far from being below.

whoever called me out at hr 42 and deleted their post   thank u...

 

 

Yes Ace called U out like U were Crazy but Either your a Genius or had early access to Nam run cause know-one thought it would blow up like U mentioned. 

 

 

Also Disregard what I wrote above about not taking Nam seriously before 36 hrs...  :whistle:

What kind of ratios are we looking at with this setup?  Based on the comments Im sensing 6:1 - 8:1 ish, but locally more while the CCB is pounding?

 

Probably decent where the surface temp is below freezing, but glop everywhere it isn't. The grounds muddy and the march sunshine won't be helping at all.

No IMBY questions, but if QPF is as high as is progged and NYC Western LI srtay cold, can the insane snows that Central Long Island had on 2/8 find it's way to NYC/Western LI?

 

Again no IMBY here, but whjat's the maximum potential in a theoretical sense if everyuthing goes "right" ?

IMHO, NAM is the best scenario for us considering the set-up. The total QPF for the storm through 81 hours is below. Some of it could be rain but if it is not and is all snow (possible considering NAM's tendency to be too warm during portions of these kinds of storms), I'd say this is the most snow (QPF x 10 of course) we would see in this set-up:
