What happened

The episode as NWS ALY wrote it up.

A high-end severe weather event unfolded across the Northeast on Wednesday October 7, 2020. A line of thunderstorms originated across New York state and moved eastward into New England during the afternoon hours, producing widespread damage. This line brushed northern portions of Connecticut, producing some tree damage across northern Litchfield County. This event was classified as a serial derecho based on the 320 mile long damage swath and distribution of significant wind gusts (75 mph and above).
