With already high water levels from periodic early June rains, 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 in the lower portions of the basin, with amounts from 7 to 11 inches around the Iowa Great Lakes
