A weak clipper system across the Great lakes will push into New England Tuesday afternoon and evening with precipitation starting as rain in the coastal plain and snow across the interior.
Light snow will develop mid-afternoon in Vermont and western New England and spread west. Most of the early evening commute should be mostly dry along the MA Pike and 495 but by around 7pm coastal showers will briefly turn into a burst of snow.
The snow will continue to come down during the evening but should tapper before midnight in southern New England. Not a lot of accumulation is excepted in Boston, where only about a coating to an inch is expected. In central and western New England 1-3" of snow are expected but amounts will quickly ramp up in Maine the farther north you go.
The storm will intensify off the Gulf of Maine Tuesday night into Wednesday hitting northern Maine with 8 to 10 inches of snow before exiting and heading out to the Canadian Maritimes.
Highs on Tuesday will be in the upper 30s south, 20s north. South winds 10 to 15 mph with gusts up to 25 mph. On Wednesday it will be very cold and windy with sun and clouds.
A few passing flurries possible. Highs near 30 south, 20s north. West winds 20 to 30 mph with gusts up to 45 mph.
