Just came in from a walk about 20 minutes ago - it's a really beautiful snowfall, as it's wet, but not windy, so the snow is sticking to the trees and shrubs perfectly. In the past hour we went from 0.5" of snow to 1.5" of snow and it's covering all paved surfaces, with even county/state roads in Metuchen (531/27) getting slushy, as temps are also down to around 30F. I'm guessing the major highways are still ok, but if this intensity keeps up past about 3 pm, we'll see accumulation even on major highways.
At this point, looking at the short range models and the radar, I'm certain we're going to reach the low end of the 3-6" forecast here and 5-6" isn't out of the question. Places to the west of the Delaware River, south of Trenton, and in NW NJ (Sussex/Warren) and the Lehigh Valley/Poconos might have a tough time reaching 3", although obs are for 2" already in some of those locations and the radar looks pretty good, so maybe 3" or more won't be so hard in those spots. Places within 20 miles of the Parkway, south of about Holmdel, are most likely to get the 5-6" amounts (except right at the coast).
Edit - just noticed NWS updated their map about an hour ago...pretty consistent with their 3-5" forecast.
