Resolution. The model has a very tough time resolving Long Island because of how the grid spacing is determined within the model. It treats the Island as part of the ocean.

I wouldn't say that, necessarily. Grid spacing would just about be even at that latitude. At 0.5 degrees, you can resolve Long Island. But none of us really know unless you look at the model land mask which none of us have.

From the latest trends suppression seems to be becoming less of an issue.

Storm will have a large circulation so you don't have to be too close to the low like during Boxing Day to reap the benefits of the CCB, which gives us a lot more wiggle room if the low adjusts further S&E.

The gfs is kinda giving me the vibes of a less severe 96 storm with its snowfall distribution.

Those are winds at 850mb, which would show a very impressive moisture feed coming in from the Atlantic. Surface charts show 30+ knot winds, which would result in likely blizzard conditions.

 

The latest GFS shows at least 12 hours of blizzard conditions in NYC. People are paying too much attention to the snow, but the wind is the big story here. We're talking about the potential for blizzard warnings along the entire I-95 corridor, from DC to Boston. 1996 did not have the kind of wind the GFS is showing.
