Sunday Evening Essentials: From Sunday Snow Scenes North to Thunderstorms South!

Thanks for all the photos and videos in the app today – Beth in Fryeburg and Dave in Lincoln captured that classic early-season look: a North Country winter wonderland. Tonight’s weather flips the script farther south as a warm front surges up the Hudson Valley. Downpours and embedded thunder lift across southern New England, with spots like Block Island already clocking an inch and a half in short order. Plan on it pouring for a time this evening, then shifting north while southern areas get a lull before rain re-fills predawn into the Monday morning commute. Expect a slow commute, with rain tapering mid to late morning and lingering pop-up downpours still possible into early afternoon before we dry out.

Northern Maine’s earlier burst of snow (generally 1–2 inches, favored by elevation) changes to rain tonight as temperatures rise; elsewhere, icing is not a concern overnight. Rainfall through Monday morning averages 0.75–1 inch, with localized 1–1.5 inches under any thunderstorm. By Monday afternoon, showers become spottier, and attention turns to the backside as colder air and a gusty west wind arrive for Tuesday.

Tuesday is wintry by feel. Temperatures top out in the 30s for most (near 40° south), but a west wind gusting 35–40 mph pushes wind chills into the 20s north/west and 30s elsewhere. Lake-effect plumes off Ontario feed moisture into Vermont, and the upslope machine fires on the Greens and Whites—steady snow in the favored west and northwest-facing slopes adds to early-week totals. A few snow showers could drift into central and northern New England Tuesday afternoon and evening; with temps dropping below freezing as early as ~8 PM, isolated slick spots may require treatment.

Wednesday brings a subtle wave that can toss flurries into southern New England, with coatings on grassy higher terrain of the NW Worcester Hills, western MA, and parts of central/northern/western CT. Highs sit in the 40s, and many of us spend Wednesday night in the 30s. The moisture we bank tonight and Monday—on the order of a half inch to an inch—is a net positive for the water table and helps chip away at northern New England drought.

Marine heads-up: With the gradient and long fetch, offshore seas approach 20 feet through the first half of the week; conditions gradually improve beyond Wednesday as the wind eases.
