A cold front and associated upper level disturbance triggered widespread severe thunderstorms across central, south-central and southeast Kansas during the evening and overnight hours of July 20th. The following are some highlights from the event. Three relatively minor and short-lived tornadoes touched down in Kingman, Barton and Butler counties, producing no known damage. The supercell that spawned the Kingman county tornado dove southeast, spreading a narrow swath of golfball to baseball size hail and 60 to 70 mph winds across northern and eastern portions of Harper county, along a line from roughly Runnymede to Danville to Freeport. Localized property and especially crop damage was extensive, particularly to the corn, soybean and milo crop. Over Butler county, a squall line spread 70 to 80 mph winds across the El Dorado area, overturning two camper trailers and downing numerous large trees at the Shady Creek Campground on the east side of El Dorado Lake. Finally, 70 mph winds heavily damaged two grain bins north of Winfield, as a squall line surged south across the area.
