Synoptically, a large upper trough extended across the northern and central Rockies.  An upper level shortwave ejected across the southern plains off of the larger scale trough, and interacted with a moist and unstable airmass east of a cold front.  The cold front was positioned along the Interstate 35 corridor when storms developed.  These storms began to impact extreme southeast Kansas and the Missouri Ozarks during the early morning hours of 22 April.  Mainly large hail and localized flooding were the primary hazards with this activity.  Other storms redeveloped during the afternoon and evening hours of 22 April.
A cold front, positioned along the I-35 corridor early in the event, was expected to cross the CWA by early in the afternoon.  During the afternoon of the 21st, a lead shortwave interacted with warm advection to kick off severe storms over Oklahoma that congealed into a mesoscale convective system which entered the SGF CWA shortly after midnight.
