A warm front was to the south of Iowa while a cold front was approaching from the Dakotas. At the same time, a moderate to strong southerly flow of air developed in the lower levels of the atmosphere. This flow drew moisture in a shallow layer of moisture northward from the remnants of Hurricane Gert. Thunderstorms erupted over Kansas and southeast Nebraska, then moved into southwest Iowa. Heavy rainfall occurred over the southwest counties of the state. Reports of 1.50 to 2.50 inches of rain were common over a seven county area. Since soil moisture conditions were at the saturation point, all rainfall quickly ran off causing widespread flash flooding. Generally speaking, the flooding was fairly minor by this summers standards, but still several roads were overtopped with flood waters. The storms did produce gusty winds and several reports of pea-size to a little larger hail. One of the storms did produce larger hail. A storm which, had reached tops in excess of 60,000 feet at one point, moved into Adams County. Hail a little larger than quarters pounded an area west of Mount Etna for 30 minutes. The actual location of most of the hail was in Lincoln Township, the northwest corner, one half mile south of the Cass/Adams County border on county road N28. Crop damage in the area was extensive.
