To be perfectly frank, I am ready to put the 2015-2016 winter season in the rear view mirror. March however, is typically the best part of the MRG season and in many years is the snowiest of all the winter months in Vermont.
We are still in the midst of a stretch of milder weather which will persist through a good part of the week. With the help of some sunshine on Wednesday, temperatures might again make a run at the 60-degree mark but clouds and some rain very late in the day might thwart that effort. Cooler weather will begin to slowly work its way back into the region Thursday; in fact, leftover moisture might result some limited snow across the high terrain while light rain falls in the valley locations. Friday begins a limited multi-day stretch of colder weather, perhaps the last such stretch this month.
Though Friday and Saturday look dry along with temperatures just below the so called "normal" threshold, a storm system will try and organize during the weekend combining jet energy in the plains with southern branch moisture in the Gulf of Mexico. Whether or not this all comes together correctly remains a question but there is a decent chance for some sort of east coast event Sunday the 20th into Monday, March 21st. Yes, one of the scenarios does call for a decent interior New England hit. The storm system would lack the strength to be historic storm but could produce as much as 12-18 inches of snow. That would be the upside. The downside is another in a litany of misses for Vermont this year.
Cold weather will continue to grip the region through the 22nd but will give way to more mild weather for the last week of the month. The limited blocking that was supporting the cold weather around the Spring Equinox will deteriorate plus the jet in the Pacific is expected to tighten. The storm late this weekend may be the last chance for a significant taste of winter though as Eric at MRG said, stranger things have happened.
