Joplin High School
On May 22, 2011, a tornado that killed 161 people in Joplin extensively damaged the high school and Franklin Tech. The high school's graduation ceremonies had just taken place about three miles away on the Missouri Southern State University campus shortly before the tornado struck.
According to principal Kerry Sachetta, "You see pictures of World War II, the devastation and all that with the bombing. That's really what it looked like. I couldn't even make out the side of the building. It was total devastation in my view. I just couldn't believe what I saw." In the weeks after the tornado, it was determined that the campus was irreparable and would need to be completely rebuilt. 
Planning for a temporary school began four days after the May 22 tornado. School officials announced in June 2011 that juniors and seniors in the 2011-12 class (and possibly later) would attend classes in a section of Northpark Mall. Classes began in the renovated former Shopko location as scheduled on August 17, 2011.
Tornado outbreak of June 16–18, 2014
The tornado outbreak of June 16–18, 2014, was a tornado outbreak concentrated in the Great Plains and the Midwestern United States. Two tornadoes also occurred in Ontario. The severe weather event most significantly affected the state of Nebraska, where twin EF4 tornadoes killed two and critically injured twenty others in and around the town of Pilger on the evening of June 16. The two Pilger tornadoes were part of a violent tornado family that produced four consecutive EF4 tornadoes and was broadcast live on television. The outbreak went on to produce multiple other strong tornadoes across the northern Great Plains states throughout the next two days.
