On Sunday, November 15th, a very potent surface low moved northeast across the Great Lakes region. A cold front initially over Indiana produced a line of isolated to scattered showers, which quickly congealed into a fully developed line of thunderstorms as it progressed eastward toward and then through northern Ohio. The result was widespread, damaging wind gusts with the line of thunderstorms, and for several hours after the thunderstorms' passage. The strong surface wind gusts in the wake of the thunderstorms were the result of a tight surface pressure gradient and rapid surface pressure rises behind the cold front. Observed gusts of 60 mph+ were common. Damage was widespread to trees, power poles, roofs, and other miscellaneous items. There were also widespread power outages, with over 150k people losing power for a time.
