Well, I had to wait up for the NWS updates and the 6Z NAM, just to see if the west/snowy trend would continue and if you don't like snow, don't look at the snowmap for the NAM - see below. So, the NWS updated their snowfall maps, below, and they're a little under what I was guessing in the post above an hour or so ago, but I think they're more likely to step up in accumulations more slowly, while I'm mostly just looking at model consensus, which could be a somewhat flawed approach.
The NWS also issued warnings (pink) for all of DE, all of NJ, except Sussex/Warren (adivsories up in blue), SEPA adjacent to SNJ, and for NYC, LI, CT and the Hudson Valley, plus they issued blizzard warnings (orange) for the NJ coastal counties - a little suprised at that, especially since LI/CT didn't get blizzard warnings and are likely to experience higher winds. In addition, fortunately, this will be a dry, powdery snow which should not stick to trees/wires, so even though there will be heavy snow, hopefully, it won’t cause many power outages. Furthermore, with the extended fetch off the ocean, minor coastal flooding is possible.
Anyway, the 12Z NAM is simply insane with 16-26" from 95 to the coast in NJ, NYC, LI, CT and New England and that's at 10:1 ratios - the Kuchera map with a 15:1 ratio, roughly, which is fairly reasonable given how cold it will be (teens to mid-20s) shows 24-40" in these areas.
I'm nearly certain the NAM is overdoing it as occurs sometimes, but even if the precip is 33% too high, that would still be 16-28" vis the Kuchera algorithm. Below is the 10:1 map and the Kuchera map (roughly 15:1 ratio). If the other models follow even somewhat, we're going to see increases in those snowfall predictions. Speaking of which, the 06 RDPS was a bit less snowy than 0Z, while the 6Z GFS was nearly identical to 0Z (both quite snowy, but not NAM like), so far no evidence of a trend towards a huge solution. Like I've been saying, an explosive, but fragile setup...
