We will likely be 4-6" and it will be pretty impressive for a time. This is a quick, hard, hitting snowstorm.
There is some very late indications that it could be higher, but I think that the models are over done on that. Regardless, it is a "surprise" snow, in that it is bigger than I thought, but that second wave as being one to watch was a pretty good idea.
Enjoy the snow. More wintry stuff is coming Tuesday night and Wednesday, and that will be a tough forecast.
