Thunderstorms rumbled across much of Massachusetts this afternoon, at one point raising fears of a tornado.
The National Weather Service issued a tornado warning for the southwestern corner of the state after a trained weather spotter across the border in New York state saw a tornado spinning east towards Massachusetts.
The tornado was spotted near Copake, N.Y., at 4:52 p.m. moving east at 35 miles per hour. Forecasters warned that the tornado could affect areas such as Great Barrington, Sheffield, Sandisfield, and Otis, Mass., and Canaan, Conn.
A severe thunderstorm watch was issued by the weather service for areas west of Interstate 495, effective until 9 p.m.
National Weather Service radar showed storms rolling through the southern half of the state shortly before 6 p.m., some of them moving into Boston’s southern suburbs. A severe thunderstorm warning was also issued for southern Worcester County.
