The RGEM has good overruning for Western areas which is why it's spitting out close to an inch in most of Central and Northern NJ with not much East of the Hudson.

You can see here the excellent flow at 700mb with the moisture transport right off the ocean as the 850mb low develops off the NJ coast.

The problem for Long Island this run is that the jet max ends up too far Northeast. Look at how much the LLJ intensifies just six hours later. You want to be just north of the LLJ max for the heaviest precip.

GFS is looking somewhat similar currently, temps really constrict overrunning totals for NYC/Long Island 

 

Long Island does cash in on some coastal enhancement

The mid-levels on the GFS are much better for Long Island than on the RGEM. Look how much flatter the flow is.gfs_mslp_uv850_neus_8.png

This is more along the lines of what I was expecting to happen, although it looks to dry for the far NW zones.

The way this winter has been going with the models, it may be a waste of time to track these snow threats until getting to nowcast time.

Or just stick with climo until given good reason otherwise, which heavily favors Southeast New England over the NYC area.

I tend to agree. I'm still realing from the last storm that's why I have been quiet on this. 

Looks too warm for the city for the light overrunning precip to stick more then on existing snow. Coastal gets going to late for much more then an inch or two. I would want to be out in central Suffolk east for anything reasebling a decent hit.

Part of the problem also is that the precip is going to be hitting a bit of a brick wall thanks to the orientation of the trough and the dome of dry, cold air that's parked just to our North over Western New England. Look at the single digit dew points over Upstate New York.

The main precipitation comes in Saturday night when it's cold enough and saturated atmosphere. You're a bit too far west for this heavy precipitation, it's most likely going to be Bergen county and east.

At least by tomorrow evening the atmosphere will be plenty cold for snow without a pesky warm layer above 800 mb to worry about. It's just with these fickle Nurlun set ups the bands can shift without notice offshore or to our Northeast. But the areas north and east of NYC are generally favored for heaviest when these set ups produce.

Hopefully it's a more general area of light or moderate snow like the GFS seems to have instead of one concentrated band. That would be great for the area under that band but leave everyone else out. Hopefully it's also mostly at night-that takes the strong sun out of it and ensures cooler air.
