Although the bulk of severe weather focused to the north across South Central Nebraska on this Wednesday afternoon, parts of North Central Kansas got in on some of the early action, mainly during the noon hour. This occurred as a nearly solid line of strong to severe thunderstorms oriented in a west-northwest to east-southeast fashion lifted north across the area, with the greatest impacts across Mitchell and Jewell Counties. Reports from these counties included estimated wind gusts to 60 MPH and hail up to quarter size.  This line of storms first entered the area late in the morning, gradually gaining strength as it moved north out of southwest and central Kansas.
The primary driving force for severe weather was a powerful, negatively tilted mid and upper level low pressure system centered over Colorado. At the surface, a fairly well-defined quasi-stationary front extended across the region from southeast Colorado to east-central Nebraska, with a few areas of low pressure along it. This surface front marked a sharp division in instability, with mid-day mixed-layer CAPE values across eastern portions of North Central Kansas into the 1500-2000 J/kg range. Deep layer vertical wind shear on the order of 30-40 knots was also present, making the environment conducive to severe storm development.

With record snow melt runoff in the upper Missouri River Basin along with much above normal May and June precipitation, dam releases on the Missouri River continued to increase through the middle of June. The Oahe Dam releases were slowly increased to 160,000 CFS. The increased releases from Garrison Dam in North Dakota and Oahe Dam north of Pierre resulted in continued rises on the Missouri River throughout June. The Missouri River at Pierre rose to 19.9 feet on June 22nd almost 7 feet above flood stage. The June 2011 runoff in the Missouri River basin above Sioux City, Iowa was 13.8 million acre feet which was the highest monthly runoff amount since 1898.
The state EOC (Emergency Operations Center) continued to handle all coordination of the flood operations. Sandbagging and levee building continued into early June along the river in Pierre and Fort Pierre.  Several thousand volunteers and National Guard soldiers helped out. The National Guard soldiers also conducted 24-hour levee security and surveillance. The State Highway Patrol helped with traffic control, security, and evacuation notices. A couple Black Hawk helicopters conducted several air operations. Divers were also called upon for repair of levees.
Hundreds of people were evacuated from homes and businesses in low-lying areas. Red Cross shelters were also set up. The storm sewers were plugged in Pierre and Fort Pierre with many large pumps utilized to pump out any new rainfall. Several public areas remained closed and flooded in Pierre and Fort Pierre including several parks and a golf course. Countless numbers of flooded trees would not survive in the parks. Many homes, roads, along with some businesses were flooded in Pierre and Fort Pierre by the rising river. Also, many homes in Pierre and Fort Pierre received groundwater into their basements. Thousands of acres of farm and pastureland were flooded all along the length of the river.
Road damage was extensive from all of the heavy equipment and sandbagging efforts. The road damage along with levee removal would be in the millions of dollars. Lake Oahe north of Pierre to the North Dakota border also rose to record levels affecting several locations.
