| 18z NAM 84-hour Snow Accumulation |
Middletown, NY: 8-10 inches
Philadelphia, PA: 4-6 inches
The NAM is forecasting a major snow event going into the December 7-10 timeframe, with widespread accumulations over 8 inches possible. What is interesting is how the GFS does not go with this scenario, and does not print nearly the amount of snow shown on the NAM. In fact, the GFS refuses to show any snow for many areas that are forecasted over 8 inches by the NAM.
The ECMWF, meanwhile, does believe that this event will happen, and is actually more aggressive with the low pressure's strength than the NAM is. We will see where the low goes and if this event occurs. I am leaning towards an NAM/ECMWF blend right now.
