The Worst Tornado Outbreaks in U.S. History
Many of the outbreaks making the list occurred in recent memory, including three outbreaks in 2011 - the Joplin, MO EF5 tornado, and the massive three day event from April 26 - 28, 2011 among them. This does not include any of the tornado outbreaks from 2013 as data is still very much preliminary, and final numbers have yet to be released.
