2009 Super Derecho
The tornado outbreak and derecho of May 8, 2009, colloquially known as the 2009 Super Derecho, was an extreme progressive derecho, tornado outbreak, and mesoscale convective vortex (MCV) event that struck southeastern Kansas, southern Missouri, and southwestern Illinois on May 8, 2009. Thirty-nine tornadoes, including two of EF3 strength on the Enhanced Fujita Scale, were reported in addition to high non-tornadic winds associated with the derecho and MCV. Due to the abnormal shape of the storm on radar and the extremely strong winds, many called this an "inland hurricane." Notably, this storm had a defined eye akin to a tropical storm, which occurred alongside intense sustained winds of 70–90 mph (110–140 km/h) at the surface level, not associated with the bowing convection typical of a derecho.
