Period of this weekend will bring 3 clippers dashing from Canada to the Mid Atlantic coast first one Friday- Saturday, next Monday- Tuesday and finally Thursday-Friday... All three should bring snows of at least 2-4" (perhas 3-6") north of its track... Currently every model except the GFS has the first system coming across the Ohio Valley into southern PA and exiting off NJ, with that said the GFS is pushing the system too far south, when in reality the storm may end up being too far north. Also I'd like to note that the pattern for the next 10 days may even support snow south of the storm track, that will have to be ironed out later on...
Of the 3 the last one has the best chance of phasing with southern energy maybe even in a big way, now it is obvious that I am not a GFS fan but I have said all winter that the model is pretty good at sniffing storms out down the road it just waffles around and loses the storm and really screws up the details just prior... The GFS showed my thinking about the storm on its 12z run... The details of course are not an exact, but it shows a northern stream storm phasing with energy to the south and exploding out of Ohio...
