Looks like the next snow event is in store for Wednesday night into Thrusday, with 3-5 inches this time, locally heavier amounts furhter east-that is not including the snow pack already on the ground. Everything will be the same in terms of dynamics, except it will be warm advected. Large snowflakes and fast accum. will be possibly so that's why I have went with the higher amounts. Clipper digs in low forms in offshore boundary associated with the arctic front, low clips parts of eastern LI and ravages the Cape, and Boston-thereafter phases with the clipper and secondary low forms bringing light snow for the day on thursday. Yet another Clipper rotates around the trof axis and some light snow should be excepted thursday also. After that things get interesting, because the clippers have pushed the arctic boundary further enough south, allowing energy to swing around the trof axis and become negatively tilted-allowing enhancment of precip (greater then 2 inches of snow) and bombs off the new england coast with 120 kt jet orientating itself in a position that could warrant a wind advisory with us being in the warm sector (no inversion). Seems like the GFS has caught on to this idea, after every other model caught on to it...seems very likely at this time but will want to see more packages before jumping on amounts....keep in mind that's next weekend.
