This a nice overnight discussion from WPC
 
	Northeast...  
	Days 1-2...   
	A deep upper trough traversing the Mississippi Valley on Sunday  
	spawning a wave of low pressure in the Southeast will track up the  
	Southeast coast Sunday night and off the New England coast by  
	Monday morning. Ahead of the upper trough, unusually rich moisture  
	for late January races up the Eastern seaboard Sunday night. At  
	the same time, a sufficiently cold air-mass will reside over the  
	interior Northeast. There is a slight chance (10-20% chance) for  
	freezing rain accumulations >0.1" in parts of the central  
	Appalachians of WV/VA and the Catskills. There is a rather large  
	swath of 40-60% probabilities for at least a very light coating of  
	freezing rain from the Blue Ridge and Laurel Highlands to the  
	Poconos today as well. Temperatures will not be sub-freezing along  
	the I-95 corridor to result in periods of snow Sunday evening, but 
	their more inland and elevated neighbors to the north and west  
	have much better odds of receiving heavy snow, especially from the  
	southern tier of NY on north and east into central ME. Strong  
	vertical ascent beneath the right-entrance region of a jet streak  
	lifting north over ME and southeast Canada, combined with  
	anomalous moisture content (PWs >90th climatological percentile 
	according to NAEFS at 06Z Mon), will account for heavy periods of  
	snow from the Catskills and Adirondacks on east to the Berkshires,  
	southern VT and NH, and just north of the ME coastline Sunday  
	night into Monday morning. After the initial front end thump via  
	850-700mb WAA Sunday night, the 850mb low forming over the  
	southern New England coast early Monday morning directs low-level  
	moisture flux within easterly flow back into southern New England.  
	This conveyor belt of Atlantic moisture will lead to a brief  
	deformation axis of snow that could result in a couple inches of  
	snow across southern New England on Monday morning. Latest WPC  
	PWPF shows 40-60% probabilities for >8" of snow in the Catskills,  
	northwest MA, and portions of the Green and White Mountains of VT  
	and NH. There are also some
