This one has been an absolute pain to forecast for.  The basic setup is cold air in place, that's been with us this week.  A messy bundle of energy coming at us from the SW that will be able to load up with lots of Gulf Moisture.  The models we use have been all over the place between absolutely nothing and a big snowfall.  Obviously we're dealing with latitudinal placement of the track of the low, making or breaking the forecast.  Unless we run into some sort of mesoscale features well north of the track of the low complicating things, I think we'll see some light snow develop during the day Friday, continuing into Friday night.  Places like Oswego could pick up an inch or two, while Ithaca, Cortland Norwich may end up closer to 4 inches or so by the time things are winding down Saturday morning.  Some accumulating snow I do see, but not a big dumping of snow.  At least at 1:45 on Wednesday afternoon.
