Two long lived supercells wreaked havoc across portions of north central and northeast Kansas on the night of June 11th. Three significant tornadoes touched down, caused millions of dollars in damage, killed two, and critically injured three citizens. The town of Chapman saw the most extensive damage. Approximately three-quarters of the town were damaged by the tornado that passed through. Numerous homes were demolished, as were both the middle school and high school. One death occurred in Chapman, as a result of flying debris striking a young woman while she protected her child. The most severe, but more localized damage occurred in the Miller Ranch neighborhood in Manhattan, where several homes were completely destroyed. The Soldier, Kansas tornado was responsible for the other death. A man was killed in his mobile home when it flipped several times and was found a few miles from it's original location. The unoccupied home a few hundred feet from the mobile home went virtually untouched. Thousands of citizens turned up over the next few weeks to help with the clean-up effort in both Chapman and Manhattan.

The tornado touched down to the southwest of Manahattan on a farm, and first destroyed a large machine shed, and threw a grain cart into an adjacent field. The tornado tracked to the northeast and destroyed several homes that were in the process of being built. Then, the tornado entered the Miller Ranch area of Manhattan, where the EF-4 damage was observed. Fifteen well built homes were completely destroyed. Nearby in the Amherst residential area, approximately thirty homes were damaged. A local newspaper reported that 45 residences in Manhattan were destroyed, 142 were damaged, and 637 were affected by the tornado. Ninety three apartments or duplexes, twenty mobile homes, and ten total businesses were impacted. Thereafter, the windows at the Little Apple Honda/Toyota car dealership were blown out, and several cars on the lots were tossed. A nearby hardware store and several self-storage units were demolished. Other nearby businesses were also damaged. The Lee Elementary School was then damaged. The tornado continued toward the Kansas State University campus. There, the roof was blown off a fraternity house, windows were blown out of buildings, the USDA Wind Erosion Labratory roof was damaged, and debris from damage to the southwest was blown across the campus. Summer classes at the University were shuffled around to find appropriate, undamaged buildings to hold summer students. New student orientation was also going on the week the tornado struck. It was reported that $37 million dollars in damage was done to the KSU campus alone.||The total preliminary damage estimate from the Manhattan torando was approximately $71 million. Off-campus, $22 million in structural damage was reported, as was $7 million in vehicle damage.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Moderate Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:54 UTC.

41 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
