A thunderstorm complex formed over eastern Nebraska during the evening of the 22nd. The complex grew upscale into an MCC as it moved into Iowa. Thunderstorms produced very heavy rainfall over southern Iowa. A large area of two to four inch rainfall occurred over southern Iowa. There were spotty reports near 5 inches. The rain fell in areas that had received significant rainfall during the previous two days. Flash flooding was reported in the Murray area of Clarke County. Water was reported over U.S. Highway 69 south of Osceola. Water of 12 to 18 inches in depth was reported in the Murray area with numerous roads closed, including Highway R15. A line of strong storms moved through the Mason City area and dropped 1.5 inches of rain in about a half hour. The heavy rain caused flash flooding in town and the roof of a Walmart store collapsed from the weight of the water. Once the flash flooding ended, generally flooding continued through the afternoon and evening. The most significant was in Clarke County where flood waters nearly closed Interstate 35.
