Precipitation on Tuesday will break out from west to east.
Snow will start during the morning commute first in Western Massachusetts, the hills of Northwest Connecticut, and in Vermont.
Over the course of the commute it will spread into parts of Central Massachusetts, New Hampshire, and Western Maine.
Near the coast rain will fall, with perhaps just a few wet flakes here or there. It will be a slower than normal morning commute for many along and outside of I-495.
The rain/snow line will slowly creep north during the day.
Accumulations will mainly be on the order of a dusting to two inches for the hills of Northwest Connecticut, parts of Central Massachusetts, far Southern New Hampshire and along the immediate Maine coast.
Even though snow won’t be all that impressive in these areas, pockets of freezing rain will ensure slick conditions prior to the change to plain rain.
Totals will ramp up in far Western New England and in Northern New England. Many in those spots will see more like three to six inches, with six to 12 inches in the highest mountains.
The storm winds down late Tuesday, and very cold air rushes in on Wednesday with a few more snow showers and squalls.
The cold air, keeping highs only in the 20s and 30s, stays locked in place through Friday.
Another system will try to graze us with some rain or snow late Friday into Saturday.
