It’s starting to look and feel like winter across New England. Bretton Woods’ Cog Railway cam, Loon Mountain’s summit view, and the Katahdin Tower cam are all showing fresh snow on the high terrain—and we’re likely to add more in the days ahead. You can see those Boston & Maine Live cameras cycling on the left side of our 24/7 weather stream, and the lower-left panel carries the live national airport delay map—handy with holiday travel ramping up.

The pattern is primed for chilly hits of polar energy. A more energized trough digs through the Great Lakes as a developing polar vortex lobe firms up across Canada. That northern energy taps colder air and, late Sunday, tugs some southern moisture north. The result is a Sunday evening and night system that arrives as snow in the northern high terrain, briefly mixed to some valleys, then flips to rain as a warm nose sneaks in. Behind it, a burst of colder air settles over us Monday night into Tuesday, which keeps upslope snow going across the favored northwest-facing slopes of the Greens and Whites.
Saturday starts with leftover showers – already gone by late morning for most, lingering longest on the Cape and across eastern Maine – then turns into a better afternoon. Saturday night dips to the 30s (20s north), setting the stage for a chillier Sunday. Much of Sunday morning to midday is dry, but by early-to-mid afternoon showers enter western Connecticut and western Massachusetts, while northern New England cools enough for snow to break out across the mountains. Late day, some valleys may even briefly see a mix before a change to rain. By Sunday night, rain fills in across much of New England.
Snow totals ramp in two steps: by Sunday evening, expect a coating to an inch near and just north of the Notches, with 1–2 inches on the higher ridges. As colder air deepens and upslope takes over Monday into Monday night, totals build to 4–6 inches in far northern New Hampshire—Pittsburg, Lake Francis, and First Connecticut Lake—with additional accumulation on windward slopes. It’s not a big wind event for most, but late Sunday into Sunday night gusts commonly reach 25–30 mph, with localized 40+ mph downsloping along the west slopes of the Greens and the northwest slopes of the Whites; plan for some rough pockets there into early Monday.
Temperatures behave seasonably ahead of the system, then trend colder. Saturday turns pleasant after the morning exit. Sunday night isn’t “warm,” but it’s just warm enough for many lower elevations to change back to rain. Monday brings scattered showers with highs in the 40s to near 50 (mid to upper 50s south), a rather dismal feel. Tuesday turns colder and breezy, drier in southern New England while upslope snow continues north, and highs only reach the 30s to lower 40s—our coldest feel of the season so far.
