Boston, Massachusetts – Massachusetts heads into Thursday under a weather alert for unseasonable heat and isolated storms, with conditions that could cause travel delays and power disruptions during peak afternoon hours.
According to the National Weather Service in Norton, Thursday will bring temperatures near 90°F across much of eastern Massachusetts, with a slight chance of thunderstorms after 1 p.m. Winds will shift from west to southeast later in the day, with gusts up to 9 mph. While storm chances remain at 20%, the timing and heat combination could catch drivers and outdoor workers off guard. Commuters along I-93, I-95, and Route 1 should monitor for brief downpours or lightning between 2–6 p.m.
Boston, Quincy, and Lowell will be most affected, with heat index values possibly pushing higher than the actual air temperature. Hydrate frequently, limit time outdoors, and avoid strenuous activity during peak heat hours. While Thursday night will remain mostly cloudy, relief is minimal with a muggy low near 69°F.
Looking ahead, Friday brings a 60% chance of thunderstorms, especially after 5 p.m., and Saturday’s storm chance climbs to 70% as another system rolls through. Storms could be more widespread over the weekend, increasing the risk of flash flooding in poor drainage areas.
Warnings remain possible into Friday and Saturday. Monitor local alerts for updates.
