Starting June 20, the area was impacted adversely by several very slow moving mid-level waves which drifted across the northern and central Plains and interacted with a nearly stationary region of baroclinicity during the following week. High precipitable water and persistent lift forcing resulted in a widespread 3 to 6 inches of rainfall, with amounts from 7 to 11 inches around the Iowa Great Lakes. Crop and pasture land was inundated for almost a month, along with many roads and city parks.
