Friday is looking like your classic "over-running" snow event. This is when large amounts of warm moist air is pumped up on top of a cold air mass. Usually this will create a wide swath of moderate to heavy snow. There are still some uncertainties on the placement of the front, which will be key to who will see the heaviest snow.
Also, the ECMWF (a reliable model) shows a coastal low developing on Saturday. It has this low hugging the coastline as it heads up to New England. The ECMWF ensemble (even more reliable) shows this low a little farther off the coast with colder conditions, which would be more favorable for snow in our region. At this point, I would say a storm is looking more and more likely. However, as we all know...track is everything! A lot will change from now and then, so we will continue to bring you updates.
