North of 78 it's 5-7" and I mean literally north per this gfs run city and coast could have precip issues

If the storm comes in too fast like the GFS has, the cold air will be too late and a lot of what falls near the coast will be nonaccumulating slop or rain. The storm is also weaker on the GFS so there is less dynamic to bring down the cold air. The NAM is about a perfect scenario for this-it really starts to strengthen, it holds back a little so the cold air has time to arrive, and the intensity means a fast accumulating snow for 6 hours or so. This will be a thump-and-go no matter what, it's on a quick moving frontal boundary and no blocking to slow it down.

The 925mb warm layer shifts Southeast of NYC between 03 and 04z. So roughly half the precip in the city falls with 925mb above freezing. 

The surface on the other hand remains above freezing for a few more hours.

Verbatim for the coast the GFS is rain to sleet to a few inches of sloppy snow early Thursday morning.
