A slug of deep, tropical moisure aiding in the production of intense thunderstorms and embedded tornadoes along the Gulf of Mexico coastline will move northeast by midweek, resulting in very effective precipitation production when it collides with cooler air in the Northeast. Although the air is cool enough to produce a clash that results in heavy precipitation for one and all, not all spots will be cold enough for snow. Where the air is sufficiently cold for accumulating snow, however, a heavy, wet snow will fall - particularly in lower elevations - with higher terrain seeing a slightly lighter consistency and, accordingly, somewhat higher amounts. All tolled, this leaves the Ski Country of New England and New York State in the "sweet spot" for a foot or more of snow! The farther south and east one is, the less snow is expected, largely because of the combination of a wetter snow consistency, and eventually a change to rain.
At this time, timing looks like overnight Tuesday night snow developing in Southern New England, rain close to the coast...with the rain/snow line slowly pushing inland Wednesday morning, but not before a slippery and snowy morning commute inland, primarily outside of Route 495, with some lingering slush possible to about Interstate 95. Ther rain/snow line slowly works farther inland and north during the day Wednesday, but never arrives to most of Vermont, high terrain of Western Massachusetts, Central/Northern NH and most of Maine - this is where I expect highest snowfall accumulations.
Anywhere with greater than five inches of snow forecast may see scattered power outages.
