Caribou, ME – Low clouds hang over northern Maine this early Sunday, hinting at the brief rain expected later in the day. After a few light showers, the state will settle into a stretch of calm, cool weather — the kind that signals the first real bite of late fall as Halloween week begins.
According to the National Weather Service, highs today reach near 45°F before a few passing showers move through between noon and 3 p.m. Rainfall totals stay light, less than a tenth of an inch. Skies clear by Monday morning as colder air moves in from the north, setting up crisp mornings and sunny afternoons through midweek.
Monday and Tuesday bring highs near 50°F with plenty of sunshine, but nights will turn cold — dropping to the low 30s, with some valleys likely touching the upper 20s. Residents should protect late-season plants and be alert for patchy frost during early morning hours.
By Wednesday, the region stays dry under mostly sunny skies, perfect for outdoor cleanup or late-fall decorating. Halloween Friday looks ideal for trick-or-treaters — dry, partly cloudy, and chilly by sunset, with temperatures in the low 40s.
Looking beyond the weekend, models hint that the quiet stretch won’t last long. Another system could approach from the Great Lakes early next week, opening the door to colder air and the season’s first flurry potential — a chilly November ahead seems likely.
