As of Tuesday morning, Logan Airport (KBOS) was reporting clear skies and about 64°F, a mild start that will set the stage for a warm day across Greater Boston. Inland highs should climb toward 72°F, with a late day shot at showers and a few thunderstorms that could roll in right around the evening commute.
Afternoon Thunderstorm Risk
Showers and thunderstorms are possible after 5 p.m. Tuesday, with the best chance lining up in the late afternoon to early evening, roughly 4 to 8 p.m. Most storms look to be brief, but a few isolated cells could pack strong, gusty winds and heavy downpours. A widespread severe weather outbreak is not on the table. According to the National Weather Service Boston/Norton, the city’s chance of precipitation this evening is around 30%, higher for inland spots.
Coast Versus Inland And Marine Conditions
Coastal neighborhoods will run cooler, mainly in the 50s to low 60s, while inland communities warm into the low 70s. Small Craft Advisories remain in effect for parts of the harbor and nearby coastal waters into the late morning and early afternoon, so mariners should expect choppy seas and plan trips with some extra caution. For more background on the warm up and harbor gusts, see our earlier coverage of gusty harbor winds.
Plan For The Evening Commute
If you have outdoor plans or expect to be on the road during the evening commute, it is a good idea to bring rain gear and budget some extra time. Brief downpours and lightning could slow traffic and create pockets of standing water. Secure loose patio furniture ahead of time, and avoid sheltering under trees if storms move in. Ferries and small boat outings may be delayed or disrupted while marine advisories are in effect.
Bottom line: enjoy the dry, mild first half of the day, but keep an umbrella handy and an eye on the sky for this evening. Updates will follow if any marine or severe weather headlines are issued.
