An area of low pressure and associated cold front initiated a vigorous complex of severe thunderstorms across western South Dakota during the evening of June 12th, and these storms tracked east-southeast to affect south central SD after sunset and into the early morning of the 13th. These storms produced destructive straight-line winds of, based on damage assessments, up to 115-130 mph in Jones County, as well as three tornadoes, two of which were rated EF-2 in Jones County following the destruction of property on multiple farmsteads. Additional thunderstorms then redeveloped and reached or nearly reached severe limits across portions of central South Dakota, and training storms brought heavy rainfall of locally 3 inches or more in and around the Pierre and Mobridge areas. Finally, intense non-thunderstorm winds developed on the backside of this system during the early morning hours of the 13th, and impacted much of central and northeastern South Dakota. Some of the peak measures wind gusts include 78 mph five miles SSW of Miranda, 75 mph three miles south of Conde (the roof of a bar was blown off in Conde), and 73 mph six miles SSW of Peever. A Presidential Disaster Declaration was requested and then granted for six counties across South Dakota, Jones and Spink among them, to help residents recover from storm damage that took place from June 11-14th. Initial estimated statewide damage to public infrastructure is assessed at 1.6 million dollars.

Location: VAN METRE
Magnitude: 104.00 EG
Reported by: NWS Storm Survey

Significant damage occurred along Van Metre road between 234th St and 237th St. This included 3 farms which sustained significant damage. The first farm lost an entire section of roof off an open gable style roof on the primary residence, hay bales were toppled over, a trailer rotated and tipped to the east, a bulk feed bin, along with other debris, was tossed and spread over a half mile east. The next farm also lost panels off the cross gable style roof, dented grain bins, a bent flag pole, a combine header moved 100 yards to the east, and other farm equipment displaced. A deck was completely destroyed. Debris from the farm was spread at least a quarter mile east. The third farm had a feeder wagon flipped, a machine shed completely destroyed, a second outbuilding destroyed and two empty grain bins ripped from the foundation. Debris from the property was spread at least a quarter mile to the east. The damage across these three farms was extensive and was caused by intense and persistent straight line winds. Eyewitness accounts and radar data suggest severe winds stronger than 60 mph lasted for 15 minutes straight with no reprieve. At the peak, winds are estimated to range from 115 to 130 mph. This is concurrent with major loss of roof panels on both homes; both of which exhibited strong roof construction.

Reported by: NWS Storm Survey

The track started near 239th street, about 0.75 miles east of 264th Ave. The path was clearly noted through a shelter belt. The tornado continued another half mile where it damaged a farm. The primary residence had a quarter of the roof panels ripped off a gable style roof and multiple windows and glass doors blown out. Two outbuildings were completely destroyed. Another shed lost the entire tin roof. The debris track from the farm continued for about a quarter of a mile northeast. The resident���s pickup truck also noted damage including the back window broken and dents from flying debris. The tornado weakened, but continued roughly 3.5 miles northeast to Van Metre Rd where it damaged another farm.  At this property a farmhouse had shingle damage to only half of the roof. A well-built machine shed was missing about a quarter of the roof panels. A grain cart was also flipped to the north.

Location: OKATON
Tornado F-scale: EF2
Reported by: NWS Storm Survey

A brief tornado touchdown ripped five large grain bins from their base. The bins were well anchored, in fact, large pieces of cement remained attached to the pins when they were pulled out. The bins were projectiled into two machine sheds and eventually carried about a half mile to the east southeast. Other debris, including a water tank and a dumpster were also tossed east. Other farm equipment was also damaged, including a tipped trailer and displaced grain auger. Pressure change inside the machine sheds also resulted in several combine windshields to be popped out. The house and machine sheds on the property sustained very little wind damage but were built well above normal standards, rated to withstand wind speeds at thresholds of 135 mph and 120 mph respectively.
