In response to a strong north-northeastward moving low pressure system, thunderstorm developed in a favorable environment over south central South Dakota just after midnight on the 14th, and quickly became severe with large hail and straight-line wind. Winds became increasingly extreme as they tracked northeast through the early morning, peaking between 4 and 5 AM across portions of Edmunds, McPherson and Brown Counties. Two separate personal weather stations recorded 120 mph wind gusts, one to the northwest of Roscoe and the other west of Frederick. Damage was widespread, including numerous downed trees and power lines, widespread roof, outbuilding and grain bin damage, and 16 steel towers were downed about 7 miles west-southwest of Frederick, which is indicative of 130 mph wind speeds. 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.
