The May 2009 Southern Midwest Derecho was an extreme progressive derecho and mesoscale convective vortex (MCV) event that struck southeastern Kansas, southern Missouri, and southwestern Illinois on May 8, 2009.[9][10] 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.[10] Due to the abnormal shape of the storm on radar and the extremely strong winds, many called this an "inland hurricane."[11][12] A new class of storm, the Super Derecho, has been used to describe this event after analysis in 2010.[13] Embedded supercells produced hail up to baseball size in southern Missouri, a rare event in a derecho.[2] A wind gust of 106 mph (171 km/h) was recorded by a backup anemometer at the Southern Illinois Airport after official National Weather Service equipment failed.[1] This derecho was the last of a series of derechos that occurred at the beginning of May.
