Boston is waking to mostly clear skies and temperatures around 75°F Sunday morning, but the city is headed for a hot, sunny afternoon near 91°F. A west wind will add a little movement to the air, though the heat will be the main event for anyone heading outside.
Hot, Sunny Sunday Ahead
The National Weather Service Boston/Norton forecast calls for bright skies all day, with west winds between 7 and 13 mph and almost no chance of rain. Temperatures should peak in the upper 80s to around 91°F during the afternoon, making water, shade and lighter plans sensible for anyone spending hours outdoors.
Clear Night Brings A Brief Humidity Break
Sunday night stays clear, with temperatures dipping to about 70°F and west winds easing to between 3 and 12 mph. A weak front moving through during the evening should briefly lower humidity before stickier air returns Monday, and no watches, warnings or advisories are listed for Boston.
Heat Holds Through Tuesday
Monday will remain sunny and warm, with a high near 89°F and light southwest winds. A slight chance of showers arrives Monday night, mainly between 7 p.m. and midnight, but the chance of rain is only about 20%; Tuesday then returns to sunny skies with a high near 88°F.
Storm Chances Rise Midweek
Wednesday looks mostly sunny with a high near 85°F, though a few showers could develop overnight along with a slight chance of thunderstorms. Thursday brings the most unsettled stretch of the week so far, with partly sunny skies, a high near 80°F and a 50% chance of showers and thunderstorms.
Cooler, drier weather finally settles in Friday and Saturday, when highs should stay near 78°F and 77°F, respectively. Both days are expected to be sunny, with overnight lows falling into the low 60s and only a small chance of rain.
