Supercell thunderstorms developed across portions of South Central Kansas during the evening hours of the Labor day holiday on September 1st, 2014.  The storms developed along an outflow boundary just to the southeast of Wichita, Kansas, in Sumner and Cowley counties.  The storms initially produced very large hail up to three inches in diameter.  But a supercell became tornadic, producing a brief tornado in Cowley County, Kansas south of the town of Dexter, and then produced another tornado with a longer track in Chautauqua county, Kansas.  This second tornado moved across open country, but did hit a couple of outbuildings and a barn at a farmstead, producing EF1 damage.  The supercell thunderstorms eventually began to bow out, and produced a swath of 90 mph damaging winds near Elgin, Kansas.
