A productive late-season cycle will keep the Northeast’s best skiing centered on northern New Hampshire and western Maine through Tuesday morning, while Vermont gets a more uneven refresh and Mt. Bohemia plus Mont Sainte-Anne stay lighter early. Sunday is the most locked-in part of the forecast, and another colder round of snow showers Monday afternoon into early Tuesday should keep surfaces soft after a brief lull. After that, Tuesday settles down, Wednesday brings only light frontal snow, and a windier, more mixed system becomes possible Thursday night into Friday.

Confidence is highest from Sunday morning, March 22, through Tuesday morning, March 24. The models are converging well on steady snow through Sunday afternoon, then a taper Sunday night before colder snow showers redevelop Monday afternoon and Monday night. They also agree that western Maine, the northern Whites, and the higher northern Vermont peaks stay mostly snow, but they diverge more on how far snow levels briefly rise at Loon, Sugarbush, and Killington, where lower elevations may mix or get nicked by a short late-Sunday-night crust before snow returns. The safest call is for roughly 8″-18″ across western Maine and the White Mountains by Tuesday morning, around 7″-9″ for the higher northern Vermont peaks, and just 2″-4″ in the southern Greens. Snow quality starts fairly dense to moderate with SLRs mostly around 8-13:1 on Sunday, then turns lighter at roughly 13-16:1 in Monday’s colder showers. Exposed terrain stays gusty, but wind looks more like periodic lift slowdowns than a full shutdown event through this first system.

Tuesday is the cleanest reset day, with colder temperatures and much lighter precipitation after the early-week snow winds down. Most guidance keeps Tuesday largely dry beyond a few lingering morning flakes, so grooming should hold well and any fresh snow from Monday night should ski better than Sunday’s denser base. A weak front then slips through Wednesday. Here the models are converging on the timing and on this being a minor event, but they still diverge on the placement of narrow bands and how much squall-like burst potential develops. The practical outcome is modest: many resorts only see a coating to 2″, while favored northern peaks and Mt. Bohemia have the best shot at around 1″-3″. Snow levels look low enough for snow everywhere when it falls, and the breezier west to northwest flow should keep the snow surface from going springlike.

Another system is likely Thursday night into Friday, but confidence drops sharply after Wednesday because the models agree on its arrival more than they agree on its details. All of the guidance points toward another period of precipitation and a windier mountain setup, yet the spread on snowfall, snow levels, and snow quality is much larger than it is in the Sunday-to-Tuesday stretch. The colder solutions keep much of northern Vermont, northern New Hampshire, Maine, Quebec, and Mt. Bohemia snowier and deliver another 3″-8″ refresh, while warmer solutions push snow levels up into roughly 2,000-4,000 feet at some eastern mountains and cut back lower-elevation accumulation, especially around Loon, Sunday River, and Killington. Wind is the steadiest signal in that period, with exposed summits likely gusting 40-60 mph. Beyond Friday, the broader pattern still leans cool in the Northeast through the end of March, so expect intermittent light snow chances rather than a prolonged warmup or washout.
