Thunderstorm Wind in Marion County, Ohio

Marion Municipal Airport ASOS recorded a peak gust of 67 mph from a downburst. This downburst was associated with a rain shower.

All of Ohio was in the warm sector of an occluded surface low that drifted from far-northern Wisconsin toward western Lake Superior during the late morning through early evening of April 9th. Aloft, a shortwave trough advanced northeastward from southern Lake Michigan and the Mid Ohio Valley toward Lake Erie as the disturbance revolved around a 500 mb low drifting northeastward from northern Wisconsin toward the western Upper Peninsula of Michigan. Ahead of the shortwave trough, scattered rain showers impacted northern Ohio during the early evening. One of these showers managed to generate a downburst in a moderate shear/low CAPE environment.
