2011 Joplin tornado
Overall, the tornado killed 158 people (with an additional three indirect deaths), injured some 1,150 others, and caused damages amounting to a total of $2.8 billion. It was the deadliest tornado to strike the United States since the 1947 Glazier–Higgins–Woodward tornadoes, and the seventh-deadliest overall.
January 2008 tornado outbreak
A strong low-pressure area over the central Great Lakes and its associated cold front combined with intense wind shear to provide a favorable environment for supercell development. Despite only moderate instability (which meant only a slight risk of severe weather was issued by the Storm Prediction Center, and only modest probabilities for severe weather at first), supercells developed throughout the day over much of the central US and continued throughout the evening and overnight hours, continuing into the morning of January 8. The hardest-hit area was in the Ozarks, around Springfield, Missouri, where nearly continuous supercells developed throughout the evening, resulting in numerous tornado touchdowns. In addition to the tornadoes, hail larger than baseballs and damaging straight-line downburst winds as strong as 100 mph (160 km/h) were reported. At least three people were killed in Missouri as a result of the tornadoes. Two of these deaths occurred near Marshfield and there were also six injuries.
