Probably because this will likely just be an event for colder surfaces. It's going to be in the 60s on tuesday with rain so roads are going to be VERY warm and wet. Very difficult to get much accumulation on roads that are retaining warmth and when temps are barely down to freezing. The last event I had almost 3 hours of 1 to 2 inch per hour snowfall rates from late morning to early afternoon with a temp of 33 degrees, but I only got a little slushy dusting on roads and didn't even have to shovel. You really need the temp to fall to freezing or below if roads and pavement are very warm. Right now this event is looking similar with temps likely falling to 33 to 35 during the snow wednesday morning, so it probably won't be a high impact event. That said, if the models are right we could get a couple inches on colder surfaces. It would certainly be very nice to see 1 to 3 inches on car tops and grass, so I'm definitely interested in this event. Any accumulating snow is interesting to me, even if it doesn't have much of an impact on travel. Of course northwest of our area where it will be colder, there's a better chance of seeing some accumulation on pavement. But I don't expect that to happen for central Jersey to NYC.
