Boston gets one mostly dry summer day Sunday, with early-morning temperatures around 72°F and a mostly clear start before clouds build. The city should reach about 84°F this afternoon, with southerly winds around 7 to 14 mph and only a small chance of rain during daylight hours.
That quiet window closes Sunday night. The National Weather Service Boston/Norton office expects a 70% chance of showers and thunderstorms beginning after 8 p.m., followed by patchy fog and additional storms overnight; new rainfall could reach a quarter-inch, according to the National Weather Service.
Monday Looks Like The Week’s Messiest Commute
Showers and thunderstorms are likely through Monday, with a 90% chance of precipitation and a high near 79°F. Forecasters expect widespread rain, heavy at times, along with gusty winds; many spots could pick up roughly a half-inch to an inch, while a quick heavier burst could cause street flooding in poor-drainage areas.
Monday’s southerly winds are forecast at 8 to 14 mph, with stronger gusts possible. Drivers should be ready for slick roads, reduced visibility and ponding water, particularly during the morning and midday periods when the wettest weather is expected.
Tuesday Offers A Brief Reset
Tuesday brings mostly sunny skies and a high near 82°F, although a slight chance of rain showers returns after 2 p.m. The rest of the week stays warm but unsettled, with highs generally in the upper 70s to low 80s and periodic shower or thunderstorm chances from Wednesday through the weekend.
Boaters Face Rougher Water Monday
Several southern and eastern coastal waters are expected to turn rough late Sunday night into Monday, with southwest winds of 15 to 20 knots, gusts near 30 knots and outer-water seas reaching 5 to 8 feet. Small craft advisories are scheduled to begin Monday morning, so boaters should check the latest marine forecast before heading out.
