It's no secret that March is the snowiest month of the year, and fortunately this year looks to preserve that generality. A Nor'Easter will impact the region on Wednesday bringing snow stretching into Monday morning. Widespread moderate to heavy snow is expected from a band of 8-14" stretching across much of ski country. Locally deeper snowfall is possible, but moderate temperatures should limit the fluff factor keeping accumulations down. The latest GFS snowfall forecast will give you a general idea of the pattern.
For much of the area, especially at lower elevations, expect a wet snow paste job. It'll make excellent base snow, but don't be looking for a blower powder day. As it stands the surface temperatures should be borderline in many areas, but plenty of cold air exists aloft. There will be little to no chance of mixed precipitation, so icing is not a concern. The skew-T below from the Monadnocks shows the plentiful supply of cold air aloft and deep later of moisture.
What does the mean for skiing? Wednesday night should be fun where night skiing is available at places like Shawnee Peak, Gunstock, Pats Peak, Crotched, and Wachusett -- though temperatures at the latter bear watching for any rain mixing in. Thursday morning should bring knee-buster snow to much of central New England. Even higher elevation areas like Wildcat and Cannon will be looking at dense, though hopefully drier, snow and not champagne. Accumulations in northern Vermont will be lighter on Wednesday night as is typical with coastal storms. For Thursday I'd head to northern New Hampshire in search of dryer snow even if accumulations aren't as high. It'll be a hunt for quality over shear quantity. Given that Wildcat already has natural terrain open (with very thin and scratchy cover) courtesy of last Friday's nsow, they look like the best bet.
As the low passes southern New England, it is expected to wrap up and move onshore into Maine. By this point snow should be wrapping up in southern New England, but the next phase of the storm will start, and this one isn't being discussed much yet. Expect the talking heads to catch up with it soon. The potential of heavy upslope snows exists for the Friday timeframe at which time the low will be inland. Wrap-around flow will be pumping Atlantic moisture into the spine of the Green Mountains. I'm not touching any potential accumulations so far out with an upslope event, but the typically favored upslope areas look to be in great shape. I'd start thinking about making plans before things get booked up.
The plan for this weekend depends on what type of skiing you're looking for. For skiing groomers with maybe a little off-piste, southern Vermont looks to be in the best position given the snow they received on Friday coupled with Wednesday's upcoming storm. Groomed trails should be in great shape. If you're a powder hound looking for the trees, head to northern Vermont. Given the upslope nature and current base depths, Bolton, Stowe, Smuggs, and Jay are looking promising for the weekend. A bonus wild card in Bretton Woods who will do okay on Wednesday and can make out well from upslope flow. They have practically zero base depths already, but New England's only lift-serviced golf course doesn't need much snow to open its ungroomed terrain.
Looking to next week, there is another chance of a storm in the early week (Tuesday?) timeframe. Then things should moderate back towards spring conditions in time for St Patrick's Day weekend. With natural snow on the ground, it could be a beautiful weekend.
