So, the NWS-Philly almost did what I thought, as they expanded the warnings to the NJ counties along the Delaware River from Salem to Burlington and to Western Monmouth and upped snowfall amounts everywhere else, as per the map below, although not as much as I thought, as they have 4-8" along and just SE of the NJTPK from DE to Woodbridge (a swath maybe 10-15 miles wide) and 8-12" along and just NW of the TPK from DE to Woodbridge (a swath about 25 miles wide) - personally, I would've had that whole area at 6-12". They did increase everywhere NW of a line about 20-25 miles NW of 95/TPK to 12-18" (with maxes to 20"), which seems about right. Snowfall maps are below, as is the map of warnings (pink) and advisories (blue).
They issued advisories for coastal Monmouth and Cumberland (1-3" with up to 5" possible in spots), but did not issue advisories for Ocean, which surprises me; they have Ocean/Atlantic/Cape May/SE Burlington with no advisory, with <1" forecast, but their maps have a few inches for NW portions of Ocean. And the NWS-NYC extended the warnings to southern NYC, Nassau and the rest of CT, but not Suffolk, which just has an advisory. They also have 8-12" along 95 into NYC and 12-18" about 20 or so miles NW of a line, along 95, from NYC to New Haven. Note that most of the models are showing the 10-18" amounts extending to the 95/TPK corridor, so a fair amount more than the NWS forecast is possible; same for coastal sections. I still like Lee Goldberg's map, especially for areas SE of 95, which is also below.
As I've been saying, this is a powerful, potentially dangerous storm and while it doesn't look like much yet for most (maybe an inch in some places and light to moderate snow now through mid-morning with nothing on the roads), by mid/late morning, expect the snow to really pick up and to start accumulating, at least within 10-20 miles SE of 95 and all points NW of there. Where it's all/mostly snow, there will occasionally be blizzard conditions and roads will become treacherous by the afternoon and through the evening. And with heavy wet snow sticking to trees and 30-40 mph gusts, there will likely be downed trees/power lines and power outages.
