Wow, GFS looks good with this. Nice hit from maybe Islip east, 0.50"+, and 0.25"+ areawide. But we need a very fast development for snow to work out, notice how it also kills the initial overrunning snow as the coastal starts up. The 500mb/700mb pattern is good enough to regenerate snow here via a deformation zone.

True but .25 + area wide is what it had last night. Did it come slight West? Does the kicker interact lesS?

I think this aimed at New England , but can see how Long Island could pull off 6 in mid island . too close and the east end may have BL issues

This is going to be a very tricky one for NYC, since models either seem to have about nothing for the city vs. maybe 3-5" on the GFS. The upper lows close off in a good spot for most of us and have deformation snow overhead for part of the storm, which is how the snow will be generated here on the GFS. The NAM is further SE/suppressed with the upper lows and do not have this snow develop in time for us. From NYC up to about Boston, very tough forecast.

Literally a tick more west and it would be nice hit with low end warning criteria i think paul. But currently this does favor NE but the improvements were noteworthy though

Currently looks like NYC/MC out across LI would have the best shot at the deform banding. Any word on some of the non-euro globals on this yet?

GFS  3- 4 CNJ NYC  4 plus  CLI  ,  Last run of the RGEM was 5 CNJ NYC LI . See what the RGEM  says and I would blend them . The GFS  has been good this year out of the northern branch

Good signs so far that maybe the NAM is too suppressed with the upper air lows. Hopefully the Euro follows suit though, it so far has supported the more suppressed look and resulting snow hole.

I dont expect good things from the Euro , its been awful in the N branch this year . May struggle again  .

Aim for 3 , anything more , you bonus 

Thats the wise approach , we still have a few model runs ahead & this winter, if it has taught me anything, is never give up so long as there is potential sometimes you get in a pattern where it wants to snow, it needs to snow, it HAS to snow :)
