June 21, 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.


June 21, 1983:

An F3 tornado touched down in a resort area two miles west of Pollock. Eleven people fled from the southwesternmost cabin and crawled under a nearby cabin. The southwest cabin was 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 into a lake, and picnic tables were hurdles against cars.


June 21, 2013:

A long-lived severe thunderstorm developed over the southern Black Hills and moved eastward across the South Dakota plains during the morning hours. The storm produced large hail to softball size from eastern Custer to northern Jackson Counties. The softball size fell 12 miles east-southeast of Fairburn in Custer County, damaging property. This storm intensified along a strong warm front with volatile air and strong, deep layer winds into several supercell thunderstorms and a damaging line of thunderstorms/bow echo across parts of central and northeast South Dakota through the afternoon hours. Damaging winds up to 90 mph uprooted large trees and caused considerable structural and crop damage and loss of power to those along the path. The worst wind damage was located at Lake Poinsett, Watertown, and Milbank. A woman was killed, and her husband had been severely injured on Lake Poinsett when their lake house was destroyed. Numerous trees were downed along with many structures damaged or destroyed. Many trees had fallen onto homes, cabins, and trailers. The bowling alley in Clear Lake lost its roof along with numerous pole barns being destroyed along the path of the storm. Thousands of people were also left without power. Four tornado touchdowns occurred along with hail up to the size of softballs. Isolated flash flooding also occurred. Codington, Hamlin, Grant, and Deuel counties were all declared in a Federal Disaster Declaration. Total damage estimates were around 1,100,000 dollars.

1987: A tornado destroyed 57 mobile homes at the Chateau Estates trailer park northwest of Detroit, Michigan killing one person and injuring six others. Thunderstorms over Lower Michigan also drenched the Saginaw Valley with up to 4.5 inches of rain in less than six hours.
