A very strong winter storm will move through the Northeast quickly on Friday, causing widespread impacts. Binghamton, New York is expected to get heavy snow, so let's predict the 24-hr precip amount (liquid equivalent). Notice that the GFS MOS forecasts have about an inch of water (so about 10-15 inches of snow), but the NAM MOS comes in the three times that amount. The NWS forecasters seem to be going with the lesser amounts, but are warning that the storm is complex, and a small change in position could change the axis of heaviest snow.
