BOSTON, Massachusetts – The first light over the harbor casts a pale reflection on calm water, but it’s only temporary calm. The air feels damp, the breeze steady off the Atlantic — early signs that a wetter pattern is building toward midweek.
According to the National Weather Service in Norton, today stays mostly sunny and mild with highs near 54°F. Clouds move in this evening, signaling the start of an unsettled stretch. Wednesday begins quietly, but showers may develop after 7 a.m., increasing through the afternoon. A northeast wind will strengthen, gusting up to 20 mph, making the day feel cooler than the thermometer reads.
Rain expands Wednesday night, and Thursday brings the steadiest rainfall. Some spots across Route 128 and I-90 could see heavier downpours during the morning commute, reducing visibility and slowing travel. Temperatures hover in the low 60s with breezy conditions. A few embedded thunderstorms aren’t out of the question — models hint at stronger bursts of rain across southeastern Massachusetts.
By Thursday night, the system exits east, setting up a much-improved Halloween Friday. Sunshine returns with highs in the low 60s and light west winds. Trick-or-treaters can expect dry, crisp air Friday evening with temperatures dipping into the 50s — nearly ideal for outdoor plans.
Looking into the weekend, Saturday and Sunday stay seasonable and bright, highs in the mid-50s under mostly sunny skies. For now, enjoy the dry stretch while it lasts — early November could bring the first real hint of a cold snap.
