1956: Barns, granaries, outbuildings and an airplane were destroyed northwest of Conde. This was caused by an estimated F2 tornado.

1961: One or more tornadoes moved southeast along a distance from east of Aberdeen to the southeastern edge of Sioux Falls. A funnel cloud was first seen between Aberdeen and Groton and later on near Raymond. A tornado hit about 4 pm a few miles southwest of Clark with about 20 farm buildings demolished. One house was destroyed, killing an elderly lady and injuring one person. A boy was reportedly lifted high in the air and another woman carried 100 yards by winds. Both were injured. Between 4:30 and 5:00 pm, areas northeast of Willow Lake and in northern Kingsbury were hit with a total of 13 farm buildings destroyed or twisted off the foundations. Five buildings on one farm were destroyed and a house was unroofed near Oldham. The house roof was found several miles away. The tornado was of F3 strength.

1962: Hail, some as large as baseball size, but mostly golf ball size or smaller was observed between Bristol and Webster. Crop loss ranged from severe to light. Hail was 6 inches deep in some areas. A road grader was used to clear the road.

1983: An F3 tornado touched down at a resort area two miles west of Pollock. Eleven people fled the southwestern most cabin and crawled under a nearby cabin. The southwest cabin was completely destroyed and the cabin the group crawled under was moved five feet from its concrete block foundation. Four people were treated for injuries. A van, boat and trailer were demolished and a small car was heavily damaged. The tornado turned east and reformed four miles east of Pollock, where it touched down briefly and dissipated. Another F3 tornado touched down in open prairie three miles northeast of Glad Valley and moved northeast, creating a path of destruction as it progressed. On one farm, nine buildings were wiped out and scattered up to two miles away. Trees and poles were uprooted and scattered a half mile away. This tornado was estimated to be on the ground for six miles with a path width of 300 yards. A third tornado, rated F2, touched down seven miles south of Pollock. This tornado damaged several cabin roofs, a restaurant, and downed several trees. Boats were tossed in a lake and picnic tables were hurdles against cars.
