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.
Tri-State Tornado
Crossing the Wabash River into Indiana, the tornado struck and completely demolished all of Griffin, where most structures were leveled, and some were swept away. 26 people were killed there. The tornado then devastated rural areas, and clipped the town of Owensville, resulting in two fatalities in that town. The tornado then roared into Princeton, destroying half the town and killing 45 people. Large sections of neighborhoods in Princeton were leveled, and a Heinz factory was badly damaged. The tornado traveled more than to the northeast before finally dissipating at about 4:38 pm around south-southeast of Petersburg. In Indiana, at least 71 (and probably more) perished.
