For the second time in a few days thunderstorms which developed over South Dakota turned southeast along an instability axis and on the edge of a warm mid-level cap. These storms dropped large hail, very heavy rain and gusty winds as they moved along the Missouri River. This time the storms weakened well north of the Omaha area. However, before they weakened...the storms that tracked across northern Cedar caused extensive crop damage along with flash flooding.
