Two rounds of severe storms occurred during the afternoon and evening of April 8th, 2015. Storms first developed over Southern Kansas and quickly raced into Southeast Kansas during the afternoon. These storms produced 70 to 80 mph winds along with hail up to the size of golf balls. A second round of supercell thunderstorms eventually fired back to the west along a retreating dry line during the early evening over South Central Kansas and Northern Oklahoma. These storms produced several reports of  very large hail and eventually tracked into Kingman county where hail over 3 inches was reported which is larger than the size of baseballs. A brief tornado touchdown occurred southeast of Zenda, Kansas.
Another supercell thunderstorm formed over eastern Kingman county. Rotating wall clouds were reported near the town of Cheney and a tornado touched down in extreme northwest Sedgwick County and tracked into Southeast Reno county.  The tornado was rated an EF0.
