A band of moderate to heavy snow is remaining intact as it crosses NY and slowly lifts north. The NAM and GFS have been eroding this band (the reason for lower QPF to the north). We'll see how it progresses. The 21z RUC is a little more promising with snows north of Rt 2. If the clipper low can remain strong and not jump to the coast too early, it will mean greater snows for interior New England. Otherwise, it is a south and east hit. Regardless, with the 850mb low tracking near the MA/CT border, this translates to the axis of heaviest snow near Rt 2. I think a few 10 inch amounts may be recorded in north central MA. Further north, into SNH, we'll be looking at around 5 to 6 inches, with some 7" amounts in western Hillborough county.
