An unseasonably warm moist airmass was in place across the southern and central Plains on Thursday October 6th. Storms developed over south east and south central Kansas during the early afternoon hours along a weak outflow boundary. These storms produced three tornadoes over Cowley County, two short tracks are shown below and the other tornado was a very brief touchdown near Strother Field. Another very brief tornado touchdown was noted in Labette County near Bartlett. Straight line wind damage from one of the storms occurred in Allen County. Additional storms developed along a cold front that was surging east. A supercell thunderstorm developed along this feature and produced two tornadoes in eastern Saline County. In addition to the tornadoes, numerous rounds of storms resulted in very heavy rain across mainly southeast Kansas causing flash flooding along with river flooding.
