The NAM model is now on board with the GFS. It puts down similar amounts of snow but comes in even heavier, which is usually a rule of thumb with the NAM. It always overdoes snow totals 3+ days out from an event. Unfortunately, it only runs out to 84 hours, and it suspect to inaccuracies that far out anyways.
The model that forecasted the east coast storm first (Heard it hear first) the European is mapped for you. It shows the least amount of snow out of all the major models, but its track record of success cannot be ruled out. It only puts a narrow band of 2-4" down, and keeps locations that the GFS hammers completely dry. We will need to watch this system play out. It is still out over the Pacific Ocean, we will know so much more once this system crashes on shore later in the week and can become sample by the nation's weather network. The track and location of vorticity maxima will ultimately determine who sees the heaviest (if any) snow fall this time around. Either way, it will usher in colder weather next week.
