Weather History - May 22nd

Local and Regional Events:

May 22, 1963:

A late spring freeze impacted many locations reporting lows in the lower 20s. Some low temperatures include: 18 degrees in Andover; 20 degrees in Britton, 4 NW of Gann Valley, Leola and Roscoe; 21 degrees Castlewood, Ipswich, Kennebec, Redfield, 2 NW of Stephen, and 1 west of Summit; 22 degrees in Aberdeen, Eureka, 1 west of Highmore, McLaughlin, and 4 west of Mellette.


May 22, 1993:

Nearly stationary thunderstorms dumped five to seven one-half inches of rain and hail within three hours on the southwest side of Sioux Falls causing major urban flooding and a flash flood on an area creek. Water and sewage flooded at least 200 basements as the storm and sewer systems backed up. Water came up to the rooftops of many cars in the Empire Mall area. Power was knocked out at the Empire Mall and to 2600 other customers in southwest Sioux Falls. Rainwater came through the roof of the Empire Mall causing damage to some stores. Hail up to an inch in diameter fell continuously for up to one and one-half hours in parts of southwest Sioux Falls causing considerable damage to hundreds of roofs, trees, and gardens. Thousands of cars received damage from hail or water in Sioux Falls. In the Silver Glen area, a flash flood turned a typically three-foot wide creek to a hundred feet wide in places. At least five houses near this creek had severe damage caused by the rushing waters. The flash flood also tore out a section of a road adjacent to the creek, buckled sidewalks, ripped away 100-year-old trees, and floated a 5500 lb truck down the road.


May 22, 2010:

An EF2 tornado in eastern Walworth County crossed into western Edmunds County and intensified into a massive EF4 tornado as it struck several farms in its path. At the first farm, several large cottonwood trees were uprooted along with damage to several trailers. Three-grain bins were also destroyed with debris located several hundred yards to the northeast. The residence suffered some shingle and antenna damage. The tornado then tracked northeast to a second farm where several outbuildings were damaged or destroyed along with widespread tree damage. The primary residence at this location suffered no damage. Several grain cars were also rolled about 100 yards into the trees behind the house. The massive tornado continued to track northeast to a third farm to the north of Bowdle. The main residence suffered major damage to walls with part of the roof structure removed. Widespread tree damage was sustained with many of the trees completely debarked with only the stumps of the largest branches remaining. Two large garages were destroyed with the concrete slab wiped clean. The vehicles in one garage were rolled or tossed from 25 to 100 yards away. It is estimated that one car flew through the air 75 to 100 yards resting in the tree shelter belt to the north of the residence. Several other outbuildings were destroyed. The tornado then toppled six to eight metal power transmission towers as it moved to the north of the farm. One tower was sheared off from the concrete footings and traveled an estimated 400 yards. Ground scouring was visible along the path of these towers. The large tornado continued to track east crossing over State Highway 47 where a state radio tower was toppled. The tornado lifted shortly after that. The highest wind speeds were estimated to be from 166 to 200 mph.
