Interestingly, sub-32F temps have made their way down the Hudson Valley and into NYC/NENJ over the past 2 hours, with light freezing rain accretion now being reported all over the place on colder surfaces; oddly areas in NJ west of about the NJ TPK between 78 and 80 are still above 32F - seems like topography is allowing the cold air in the Hudson Valley to drain more easily down the Hudson on light northerly winds, due south into the urban areas of NENJ/NYC. Roads don't sound like they're bad yet in the urban areas, but they might start to get bad soon if the precip keeps up with temps at 30-32F (31F in Central Park right now, where slippery sidewalks are being reported). This could definitely end up more serious than most of us thought a few hours ago, even.
Haven't seen temps below 32F, yet south of 78 in NJ, but it looks like that should happen in the next hour or two, which could put down a glaze of ice for much of Hunterdon, Mercer, Somerset and Middlesex Counties (and Bucks/Montco in PA). As always, very tricky forecast when 1F can make a big difference.
