Good afternoon, A Severe Thunderstorm Watch is in effect through 11 PM for western Massachusetts, and much of Connecticut. The main threat is damaging straight line winds gusts and heavy downpours which may lead to flash flooding. In addition, an isolated tornado cannot be ruled out. We've also attached the Flash Flood Watch that remains in effect until late tonight.
