BOSTON, Mass. – Fall’s calm spell holds a little longer across eastern Massachusetts this weekend, but the pattern begins to shift by Monday. Early risers felt the crisp air Saturday morning as clear skies and a northwest breeze pushed temperatures through the 40s—ideal for late yardwork or early Halloween prep. By Sunday, that stillness gives way to building clouds and a steady breeze signaling change ahead.
According to the National Weather Service in Boston/Norton, a weak coastal trough slides in late Monday, bringing the region’s first widespread chance of light rain in over a week. The system should move quickly, but enough moisture could dampen the afternoon commute along I-95, I-90, and into Cape Ann. Winds will turn north, gusting to 20 mph at times, making for a rawer, more November-like feel.
Tuesday looks cooler still, with high temperatures hovering near 52°F and spotty showers continuing through midafternoon. Gardeners should secure lightweight decorations and cover tender plants, as temperatures may drop into the low 40s under thicker cloud cover. While no frost threat looms yet, early-model signals suggest colder air pushing south by mid- to late-week.
Wednesday could bring one more round of light showers before drier, cooler air returns Thursday. Trick-or-treat conditions for Friday currently look dry but brisk—jackets over costumes will likely be a must. After all, the first true November chill isn’t far off.
