Well at first to me it looked like this upcoming storm would be mostly snow but not accumulate to more than half an inch or so. The latest NAM and GFS at 00z just came out showing a colder solution than the previous runs. If the model below is correct 2-4 inches across most of Morris, Sussex, and Warren counties with 4-8 inches across the areas above 1,000 feet. Let's see what the models tomorrow say, if they stay with the current solution, or get colder than things could get interesting.
