| episode_narrative | During Friday, June 20th, very warm, moist and unstable air was in place across much of Michigan's Lower Peninsula, ahead of a strong, slow-moving cold front across the western Great Lakes region. Atmospheric conditions were ripe for the development of strong to severe thunderstorms containing wind gusts to 70 mph and very heavy rain. Numerous thunderstorms reached severe criteria due to damaging wind gusts. However, the most significant damage was caused by flash flooding across Allegan and Ottawa Counties, which was caused by the training effect of slow-moving thunderstorms during the day, followed by a line of severe thunderstorms which moved through during the early evening hours. Thunderstorms during the day saturated the soil across the counties, then heavy rainfall of 1 to 5 inches in a 2 hour period from a line of severe thunderstorms during the evening created extensive runoff, resulting in extensive flash flood damage. |
