June 18th, 2011 Severe Weather Event

  Main Menu

 Conditions were ripe for the third day in a row for severe thunderstorms to develop across Kansas.  During the afternoon of June 18th, 2011 a surface low pressure was set up over central Oklahoma, with a frontal boundary draped across south central Kansas and northward across eastern Kansas.  An upper level disturbance was moving into the region which would only help the thunderstorm dynamics.   During the afternoon the warm moist sector over northeastern Oklahoma and southeastern Kansas destabilized.  By early evening thunderstorms began to develop along and near the Oklahoma/Kansas border and northward into south central and southeastern Kansas. 

The first storm to develop became a very strong supercell and had indications of being tornadic by early in its lifecycle.  This storm tracked right along the Oklahoma/Kansas state line from Sumner to Montgomery counties in southern Kansas.  This storm dropped up to tennis ball sized hail in Cowley county and eventually did produce a tornado as it slowly moved southeast in Osage county Oklahoma.  This was not the only storm, as other storms developed in south central and southeastern Kansas dropping ping pong sized hail, with some areas receiving golf ball sized hail.  

A few more waves of severe thunderstorms developed across Sumner and Sedgwick counties overnight.  These storms moved eastward impacting other areas of south central and southeastern Kansas.  These storms produced some large hail and strong winds and locally heavy rainfall.
