Missouri
Located in Tornado Alley, Missouri also receives extreme weather in the form of severe thunderstorms and tornadoes. The most recent tornado in the state to cause damage and casualties was the 2011 Joplin tornado, which destroyed roughly one-third of the city of Joplin. The tornado caused an estimated $1–3 billion in damages, killed 159 (+1 non-tornadic), and injured over 1,000 people. It was the first EF5 to hit the state since 1957 and the deadliest in the U.S. since 1947, making it the seventh deadliest tornado in American history and 27th deadliest in the world. St. Louis and its suburbs also have a history of experiencing particularly severe tornadoes, the most recent memorable one being an EF4 tornado that damaged Lambert-St. Louis International Airport on April 22, 2011. One of the worst tornadoes in American history struck St. Louis on May 27, 1896, killing at least 255 and causing $10 mil. damage ($3.9 bil. damage in 2009) or $ in today's dollars.
Marion, Illinois
On May 29, 1982, one of the larger tornadoes in Illinois history, an F-4, hit the city of Marion, Illinois and Williamson County. Ten people died and 200 people were injured after this tornado ripped across a stretch. The Shawnee Village apartment complex was destroyed, and the Marion Ford-Mercury dealership sustained heavy damage. This tornado caused between $85 million and $100 million in damages. A memorial to the ten people who perished that day was later erected on the Tower Square.
