Models are indicating a powder day on Tuesday particularly from Mansfield to Jay Peak.  
BTV WRF model showing over 2" QPF bullseye over Mansfield.  NWS talking Advisory level 
snow on Monday night with over 1.0" liquid equivalent in that Mansfield to Jay corridor.  
That would imply a foot at summits.

Here's the BTV disscusion which sums it up:

Short term /11 PM this evening through Tuesday/... as of 400 am EDT Sunday...the 
chances for precipitation increase on Monday into Tuesday...with some accumulating snow 
likely for the mountains above 1500 feet late Monday into Tuesday. Advisory type snow 
possible on Monday night...especially northern greens and parts of the dacks. Deep closed 
middle/upper level circulation will retrograde west toward northern Vermont by Monday 
and rotate plenty of deep Atlantic moisture into our central and northern County Warning 
Area. Meanwhile...a westerly follow from the surface through 850 mb will enhance low 
level lift...especially across the western slopes and northern dacks on Monday into 
Tuesday...with downslope shadowing resulting in less quantitative precipitation forecast 
across the cpv and parts of the CT river valleys. Both NAM/GFS and our local mesoscale-
scale models show a favorable low level blocking scenario developing with a westerly 
follow...which should place higher quantitative precipitation forecast amounts across the 
immediate western slopes from Mount Mansfield to Jay Peak and across the northern 
dacks on Monday into Tuesday. Quantitative precipitation forecast fields off the GFS/NAM 
both show over 1.0" possible near Jay Peak to Mansfield...with less than 0.10" at 
btv...showing the very sharp precipitation gradient which is very typical of these events. 
Thermal profiles will be tricky...with best potential for accumulating snowfall on Monday 
night into Tuesday morning above 1500 feet across the central/northern greens. On 
Monday...feel bl temperatures warm between 1 and 3c...with 925mb temperatures near 
2c...while 850 mb temperatures stay between -2c and -4c...supporting snow levels above 
2500ft. However...these temperatures will cool slightly on Monday night with northerly 
follow and the loss of surface heating from the high sun angle. Meanwhile...favorable 
deep layer moisture and several embedded vorts will rotate through our County Warning 
Area and enhance synoptic lift...along with favorable upslope follow/blocking will provide 
lvll mesoscale-scale lift across our mountains this low level cooling and lift will result in 
dropping snow levels with some accumulation likely by 12z Tuesday....especially above 
1500ft. Thinking a general 2 to 5 inches will be possible across the mountains...with a 
mixture of very light rain/snow showers possible across the valleys with total quantitative 
precipitation forecast <0.10 through 12z Tuesday.
