Berkshire County

Figure 1 depicts the surface observations at 2:30 am EDT, which shows a cold front off the northeast coast of the United States and a large area of high pressure across Canada. An area of developing low pressure associated with a stationary front off the coast of Massachusetts is also observed to be developing at the time of Figure 1. This stationary front could have been responsible to initiate thunderstorms, possibly aided by sea-breeze interactions, which ultimately led to this F2 tornado.
