Boston, MA – Scattered severe thunderstorms could bring damaging winds and localized flooding to parts of New England between 2 and 10 p.m. Thursday, with western Massachusetts and northern Connecticut at greatest risk.
According to the National Weather Service in Boston, a Level 2 (Slight Risk) has been issued for Springfield, Greenfield, and Hartford due to the threat of strong storms fueled by extreme heat and humidity. Heat index values are expected to soar between 95 and 100 degrees across interior southern New England, adding to the risk of urban flooding and power outages.
Cities including Worcester, Pittsfield, and Waterbury may see heavy downpours, gusts near 50 mph, and brief street flooding. While eastern Massachusetts—including Boston, Plymouth, and Cape Cod—faces a lower risk (Level 1), forecasters warn that isolated cells could still develop. The storms are expected to form as the region peaks in heat and humidity, with temperatures climbing into the 90s across much of the area.
Residents are urged to stay weather aware, especially if traveling during the afternoon commute. Avoid outdoor plans during the warning window and secure loose items that could blow away in strong winds. Keep phones charged and be ready to receive alerts.
More updates are expected late Wednesday night as Thursday’s system develops. Watches or warnings may be issued early Thursday morning.
