Boston woke up to a gray, soupy start Tuesday, March 31, with patchy fog, spotty rain showers and temperatures hovering around 52°F. Visibility is reduced in parts of the city and brief heavy downpours, with a rumble of thunder possible, may roll through during the morning commute. Skies stay mostly cloudy, with a high near 59°F before a sharp cool-down later this afternoon, as reported by the National Weather Service.
Morning Commute: Fog And Fast-Hitting Showers
Rain showers are most likely between about 7 a.m. and 8 a.m., with patchy fog knocking down visibility and slicking up the roads. Some neighborhoods could see quick bursts of heavy rain that cut visibility in a hurry, so plan on slower travel and extra puddles on surface streets. Winds start from the west at roughly 10 mph and will shift later as a frontal boundary moves through.
Afternoon Chill And A Second Round Of Wet Weather
Temperatures should peak near 59°F by midmorning, then slide into the mid to upper 40s by late afternoon as a cool front pushes in. A second round of scattered showers and a few thunderstorms is possible late afternoon into the evening, especially over the interior. If you have outdoor plans, keep a jacket handy, since conditions can turn damp and windy quickly.
Coastal Waters And Boaters
Small Craft Advisories remain in effect for portions of Boston's coastal waters through this evening, with southwest winds gusting to 20 to 30 knots and brief marginal gale gusts possible. Boaters and ferry operators should be ready for choppy seas and reduced visibility in rain and fog, according to the National Weather Service Boston/Norton. If you plan to head out, consider delaying departure or double-checking tide and marine notices before launch.
Transit And Travel Tips
Build in extra time on the roads and at stations, since low visibility and standing water can slow buses and commuter rail. Riders should check MBTA T-Alerts for real-time service updates and allow extra time for transfers. Travelers using Logan Airport should monitor airline notices, as gusty winds and heavy showers can sometimes trigger delays.
Looking Ahead
The unsettled pattern hangs on into Wednesday, with rain showers likely and highs near 61°F before cooler air pushes temperatures back down at night. Thursday turns cooler, with a high near 41°F and scattered showers, and the rest of the week stays somewhat unsettled with occasional rain chances into the weekend. If you have outdoor plans later this week, keep an eye on updated forecasts and consider staying flexible on timing.
