Today marks the 15th anniversary of the beginning of the "Forgotten Outbreak Sequence" of April 14-16, 2011. It tracked from the Great Plains, through Dixie Alley, and into the Carolinas, becoming one of the largest tornado outbreaks on record at the time. However, less than a couple weeks later, it would soon be overshadowed by the even larger, more destructive, and far deadlier Super Outbreak of April 25-28, 2011.
