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.
“There is nothing here, just heavy rain. We issued a reverse 911 warning just as a precaution, but there is nothing. Got to go. Bye,’’ said a Great Barrington police dispatcher shortly after the storm was expected to pass by. The tornado warning expired at 6 p.m.
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.
