| Brief Description: The tornado from Hanson County destroyed most of Spencer as it strengthened and continued to grow. Most homes, other buildings, and other structures in Spencer were completely levelled. Debris and belongings were scattered over a large area, and one receipt blown from Spencer was found just west of Chandler, MN about 80 miles east of Spencer. The tornado killed 6 and injured 150 in Spencer. The tornado continued southeast from Spencer, widened, then weakened, and dissipated 4 miles southwest of Salem with another tornado then forming from the same storm.

| Brief Description: A powerful supercell thunderstorm produced six tornados from eastern McPherson county and across northern Brown county during the evening hours of June 23rd. The first weak tornado (F0) touched down briefly 6.4 miles northeast of Leola and resulted in no damage. The second tornado (F1) touched down 8.5 miles northeast of Leola and crossed over into Brown county where it dissipated 9 miles northwest of Barnard. This tornado brought down many trees and a barn and caused damage to the siding and the roof of a farmhouse in McPherson county and caused no damage in Brown county. A third weak satellite tornado (F0) occurred following the dissipation of the second tornado and resulted in no damage. A fourth strong tornado (F3) developed 6 miles west of Barnard and moved east and dissipated 3 miles southeast of Barnard. This tornado brought down some high power lines along with a support tower and tossed a pickup truck 100 yards into a group of trees. The pickup truck was totaled. The tornado caused extensive damage to two farmhouses, several farm buildings, and farm equipment. One farmhouse lost its garage and most of its roof with many trees completely snapped off down low and debarked. The fifth tornado developed 5 miles southeast of Barnard and became a violent tornado (F4). This tornado caused damage to one farmhouse, several outbuildings, trees, and equipment as it moved northeast and strengthened. The tornado then completely demolished two unoccupied homes, several outbuildings, many trees, along with destroying or damaging some farm equipment before dissipating 7.6 miles northeast of Barnard. Also, a sixth weak satellite tornado (F0) occurred with this violent tornado and caused no damage. This was the first F4 tornado recorded in Brown county and one of few recorded in South Dakota. The total estimated property loss exceeded a million dollars. | |||||||||||

| Brief Description: A tornado destroyed or heavily damaged all buildings, other structures, and vehicles in the small town of Manchester. Propane and fuel oil tanks were destroyed. Many homes were stripped to the foundation. Of the six residents of the town, four were injured and were transported to hospitals. Three were deemed to be seriously injured, but non of the injuries were life threatening. One of the injured was in a basement, one was blown out of the home on the way to the same basement, and two were in a mobile home which was destroyed. The tornado damaged crops, trees, and power lines south of Manchester prior to reaching the town. The tornado also heavily damaged several farms north of Manchester, including two farms on which several buildings including the homes were destroyed. One of the farms was a "Centennial Farm". About 12 cattle were killed and others injured. The amount of crop damage was not known. During its path, the tornado was observed to have multiple vortices. The tornado was observed and video taped by numerous storm chasers and researchers. Researchers also deployed weather sensors around the town of Manchester. One of these sensors recorded a 100 millibar pressure drop as the tornado passed. | |||||||||||

| Brief Description: EVENT NARRATIVE: An EF2 tornado in eastern Walworth county crossed into western Edmunds county and intensified into a large 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 main residence at this location suffered no damage. Several grain cars were also rolled about 100 yards into the trees behind the house. The large 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 completely 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 vehicle flew through the air 75 to 100 yards resting in the tree shelter belt to the north of the residence. Several other outbuildings were completely 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 thereafter. The highest wind speeds were estimated to be from 166 to 200 mph. EPISODE NARRATIVE: Several supercell thunderstorms developed along a very strong warm front and produced nine tornadoes from Akaska to Bowdle to Hecla. The largest of the tornadoes was an EF4 tornado which occurred near Bowdle. This tornado produced devastating damage in the Bowdle area. The other tornadoes ranged from EF0 to EF2 and caused extensive tree and building damage. Nearly one-hundred power poles were downed along with several high line towers leaving nearly a thousand customers without power. Also, very strong straight line winds and large hail up to the size of golfballs affected parts of the area causing some damage. | |||||||||||

It destroyed a green house (a large tent) and it's contents in the Target parking lot, uprooted and snapped trees as it crossed U.S. Highway 12. In addition, it took out the south wall, including a large overhead door, of a cinder block warehouse, broke windows in buildings, and lifted a box car off the train tracks. It also tipped over several semi trailers (the tractors were not attached) rolled over and destroyed a motor home, and threw a pickup truck and it's occupant about 70 feet. The occupant was sligtly injured. Between Aberdeen and Bath, the tornado contained multiple vortices as it strengthened to an F3. Most trees in a shelter belt northeast of Aberdeen were snapped or uprooted and a garage was completely destroyed. Several farms were hit 1 to 2 miles north of Bath. Many outbuildings were destroyed. Two layers of shingles were peeled off a garage and several trees were uprooted. Twelve to 15 high tension utility poles were damaged or destroyed and 17 wooden poles were destroyed along the path of the tornado. The outages caused by the tornado affected several hundred customers. The tornado continued to the northeast producing F1 damage between Bath, Putney, and Claremont. It snapped and uprooted many trees. Outbuildings like grain bins and calf barns were destroyed. Debris was deposited 1 mile away in some instances. A John Deere chopper was turned 180 degrees by the twister. The tornado continued on into Marshall County where it weakened and dissipated near Amherst.
