Thunderstorm Wind in Holmes County, Ohio

Trees down about one-mile southwest of Glenmont.

A cold front moved southeastward from Lower Michigan to Lake Erie during the evening and overnight of the 15th and then stalled in vicinity of the southern lakeshore by daybreak. This was in response to one surface low moving northeastward from southwestern Quebec toward the mouth of the Saint Lawrence River, while another low moved along the front from eastern Iowa to near the Michigan/Indiana border. Ahead of the front, several multicell thunderstorms generated damaging wind gusts in northern Ohio on the 15th and 16th. These storms occurred in a warm sector comprised of moderate to strong instability and DCAPE, and moderate effective bulk shear. Training thunderstorms along and ahead of the cold front during the afternoon and evening hours of the 16th led to flooding and flash flooding across portions of the area. Widespread rainfall amounts up to one inch were reported, with several swaths of rainfall from 2.5 to 4 where the flooding occurred.
