| Brief Description: EVENT NARRATIVE: An eighth tornado touched down west of Hecla producing damage to one farm including tearing the roof off of an outbuilding and throwing several grain bins 100 yards or more. Widespread tree damage was also noted. The tornado continued northeast damaging another outbuilding and destroying an empty grain bin before lifting. Wind speeds were estimated between 112 and 120 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. | |||||||||||

| 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. | |||||||||||

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.
