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.
Tornado outbreak of April 27–28, 2002
Sporadic but strong tornadoes were reported in all four states on the afternoon of the 28th. A strong F2 tornado produced $45 million in damage in and around Jackson Township, Stark County, Ohio, and additional tornadoes were reported across southwest Pennsylvania, southwest New York, and at Saint Joseph, West Virginia. The Saint Joseph supercell produced large hail a considerable time before this tornado occurred, and the parent supercell later produced the most severe weather recorded during this outbreak, after crossing into Virginia and Maryland.
The worst damage of the outbreak was seen in parts of Virginia and Maryland. A supercell thunderstorm that had earlier produced the St. Joseph, West Virginia tornado crossed the central Appalachian mountains, producing numerous hail and wind damage reports. The supercell has also spawned an F2 tornado in Shenandoah County, Virginia, blowing multiple vehicles and trucks from Interstate 81.
