A stationary front was located across Iowa once again. It extended from near Omaha to just south of Des Moines to near the Quad Cities. Moisture rich air was to the south of the front and continued to over run the front through the day. Thunderstorms moved from northwest to southeast across Iowa during the day. The storms dropped heavy rainfall and downed many trees along its powerful gust front. The strong winds toppled a 100- X 200-foot tent at the Mesquakie Indian Reservation where more than two dozen tribe members were injured as they prepared for a Powwow dance. Most of the injuries were bruises, with some broken bones caused by falling tent poles. As the storms moved east, the main feature was the high winds. Winds gusted to 85 mph in Cedar Rapids, causing considerable damage in the city. Other reports of high winds were received all the way to the Iowa Illinois border. The storms produced heavy rainfall, but were moving rather quickly. Urban flooding was reported in Webster County, but was not of the magnitude of many of the flooding events that occurred throughout the summer.
