Boston is starting Thursday under mostly cloudy skies with temperatures around 70 degrees. Showers and a few thunderstorms could complicate the early commute, but the forecast should turn brighter by afternoon, with a high near 82. By Friday, the city settles into a sunny and noticeably more comfortable stretch.

Morning Showers Give Way To Sun

Showers and thunderstorms remain possible before 2 p.m., with only a slight chance of another passing shower later in the day. The National Weather Service Boston/Norton office says severe storms are not expected, though lightning and brief downpours could still make roads slick. No watches or warnings are currently listed for Boston.

Clearer, Cooler Weekend Ahead

Thursday night turns mostly clear, with a low near 66 degrees and a northwest breeze. Friday will be sunny with a high around 82, followed by a cooler Saturday near 78 and a low near 63 Saturday night. Lower humidity should make the weekend feel more like a late-summer reset than another day in the city’s atmospheric soup.

Rain Returns Sunday Night

Sunday starts mostly sunny with a high near 79, but a slight chance of showers arrives after 3 p.m. Showers and thunderstorms become likely Sunday night, when the chance of precipitation rises to 70%, and Monday could bring more rain before 5 p.m. Outdoor plans should be easiest Friday and Saturday, with a backup option worth keeping handy for Sunday night into Monday.
