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.
1896 St. Louis–East St. Louis tornado
The tornado spawned from the other supercell became the third deadliest and the most costly tornado in United States history. It touched down in St. Louis, Missouri, then one of the largest and most influential cities in the country. At least 137 people died as the tornado traversed the core of the city leaving a wide continuous swath of destroyed homes, schools, saloons, factories, mills, churches, parks, and railroad yards. A few of the destroyed homes were swept away. Numerous trees were downed at the Lafayette Park, and a barometer recorded a drop to at this location. Uncounted others may have died on boats on the Mississippi River, which could have swept their bodies downriver.
