Discussion: This is a particularly difficult storm to forecast snow amounts for due to the expected mixed precipiation nature to the system and the inherent uncertainties in how long each of the precipitation modes, snow, sleet, freezing rain, and rain will last, as well as an expectation that local terrain will play a big role the distribution and amounts. Therefore, forecast error will be higher than typical with this system..
.
With that said a period of moderate to heavy snow is likely to occur in most if not all areas for at least a couple of hours leaving enough snow to shovel and plow in most locations. Terrain enhancement with a strong SE flow is likely along the eastern slopes of the Catskills as well as in the higher elevations (1000' and up) in Berkshire and Bennington counties where I'm indicating as much as 5"-9", especially at elevation in these areas..
.
Cold air will last longer in the Adirondacks, along with strong upslope flow which should lead to a high end moderate snowfall of 5"-9" there as well.
.
Terrain shadowing is likely in portion of the upper Hudson valley, to Bennington, VT and the lower elevations in NW Berkshire County where amounts will likely be less, on the order of 2"-4"..
.
Another area to watch for potential elevated snow amounts in a pattern where strong SE flow is occurring, is in the Lake George/Saratoga region where past patterns suggest, if the cold air can hang on long enough, upslope flow will cause enhanced snow accumulations.
