Near-record heat and a strong short-wave trough digging southeastward across Quebec led to the development of afternoon thunderstorms, mainly along the higher terrain in central MA and northeast CT. A few of these storms produced isolated wind damage and some large hail. One storm caused flash flooding in North Chelmsford, MA.
