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.
Tornadoes of 2009
Another major severe weather event developed early on May 8 over southwestern Kansas. It quickly formed into a major progressive derecho which tracked across the central Plains, the Ozarks and into the Ohio Valley. The city of Joplin, Missouri had a derecho. It eventually became an F1 tornado destroying a TV station tower. Several tornadoes also developed, primarily in the Springfield, Missouri area where damage was reported. A moderate risk of severe weather was issued primarily due to the wind threat. Two people were killed near Poplar Bluff, Missouri when winds knocked a tree onto their car. Another Missouri resident suffered a fatal heart attack after he was blown away 
from his home and dropped into a field by an EF2 tornado. A woman was killed in southeastern Kansas after her mobile home was blown off its foundation. Two other deaths occurred in Kirksville, Kentucky from an EF3 tornado. Eventually, the storm developed a tropical cyclone-like structure, with a well-defined eye feature. In addition, winds were measured as high as in Carbondale, Illinois.
