What happened

The episode as NWS BOX wrote it up.

Severe thunderstorms ahead of a cold front brought damaging winds and large hail to northern Connecticut. Hartford and Tolland Counties experienced the most damage, with many reports of downed trees, large tree limbs, and power lines, as well as hail as large as golf balls. Newington, in Hartford County, was especially hard hit. Just over 10,000 customers lost power during the height of the storms. A large tree fell onto the roof of a parked van, light poles were damaged, and the steeple of a church was knocked down. Many streets were temporarily impassable due to fallen branches and trees.
