What happened

The episode as NWS BOX wrote it up.

A hot and humid airmass combined with an approaching cold front sparked strong to severe thunderstorms across southern New Hampshire during the late afternoon and early evening hours of 27 July. These thunderstorms produced severe winds, damaging lightning, and flash flooding across north central and northeast Connecticut, especially Hartford county.The severe winds produced from these thunderstorms brought trees, utility poles, and power lines down. In Hebron, approximately 40 trees were knocked down as these storms pushed through the area. Lightning and flash flooding were also produced from these storms. In Hartford, lightning destroyed a wooden shed. In East Hartford, flash flooding left cars stranded on a road.No injuries directly resulted from these strong to severe thunderstorms.

What forecasters said that day
