First off lets check the soundings:
These soundings are for the I-80 corridor from various models. Now most show it being all snow except for the NAM in the middle which has a weak inversion for about 3 or 4 hours during the height of the event. This would result in more ice, but the general consensus is it stays just cold enough in NW Jersey.
This snow is going to fall fast and most of it falls in the first half of the event. There is going to be an area with a lot of ice somewhere between interstate 80 and 78 which could take down branches and power lines. Let's hope for the best.
