What happened
The episode as NWS DMX wrote it up.
Another round of thunderstorms moved through Iowa, touching off minor flooding. Soil conditions were still quite saturated from the rainfall the previous week. In spite of the saturated conditions, runoff was only enough to bring rivers slightly above flood state in most areas. Damage was very minor from this event.
