On the morning of June 18, 2013 diminishing thunderstorms crossed from Southern Nebraska into Northeast Kansas leaving an outflow boundary to proceed southeastward. Meanwhile a baroclinic zone was setting up along a line from Manhattan to Ottawa evident in a building cumulus field. As the outflow encountered the boundary thunderstorms developed. The air mass ahead of the thunderstorms was plenty unstable. There was an equal amount of hail, wind, and flash flooding reported with this event including the microburst in north Topeka.
