Boston gets a warm, mostly dry Sunday, with partly sunny skies and temperatures climbing from the mid-60s early to about 85 degrees. Southwest winds will run 7 to 13 mph, making this the city's last easy outdoor window before cooler air and a wetter stretch move in.
Warm Sunday, Small Shower Chance After Dark
Clouds should increase late Sunday, but rain is unlikely through most of the afternoon. A slight chance of showers arrives between 10 and 11 p.m., with mostly cloudy skies and a low near 66; any rainfall should total less than a tenth of an inch, according to the National Weather Service.
Monday Brings A Cooler Reset
Monday turns sunny but noticeably cooler, with a high near 76 and northeast winds of 5 to 10 mph. Another round of clouds develops Monday night, and showers could arrive after 2 a.m. Tuesday as the rain chance rises to 40%.
Tuesday Looks Like The Wettest Day
Tuesday is the big forecast pivot, with rain showers expected before 2 p.m. followed by showers and thunderstorms. The high should reach only about 73 degrees, while the chance of precipitation climbs to 90%; Tuesday night keeps showers and thunderstorms in the forecast before 2 a.m., with an 80% rain chance.
Unsettled Weather Lingers Through Thursday
Wednesday stays mostly cloudy with a high near 72 and a 30% chance of showers after 2 p.m. Showers are likely Wednesday night and Thursday, when the rain chance sits near 60% and temperatures remain in the low 70s.
Cooler, Mostly Drier Finish
Friday brings partly sunny skies, a high near 71, and only a slight chance of showers. Saturday looks mostly sunny with a high near 70, although a 30% chance of rain showers develops after 8 a.m., so the week ends cooler rather than completely washout-free.
