June 21, 2019 Straight Line Wind Damage

Overview

A significant storm moved across Cheyenne County Colorado and Wallace County Kansas on the evening of June 21, 2019. This storm produced powerful wind gusts and hail ranging from quarter size to tennis ball size. Sporadic wind damage occurred with this storm along with damage associated with wind-driven hail.

A widespread swath of sporadic wind damage occurred last night across Cheyenne County Colorado and Wallace County Kansas. Damage consisted of many tree branches down and tree trunks snapped. Many power poles were downed, especially in Wallace County. There was also some damage to structures. A large grain bin was shifted 3 to 4 inches in Cheyenne Wells, in addition to two structures losing metal roofs. In Arapahoe, some minor roof damage occurred to a few structures while one home lost the entire garage building. From the west central portion of Wallace County to around Sharon Springs, more significant wind damage was noted. Numerous irrigation pivots were overturned across the county. A few farmsteads were hit harder, with one in particular losing two large farm structures due to wind. Just west of Sharon Springs, another two buildings were collapsed from the winds.

What was interesting about this event was the varying directions of the wind. In some areas, the debris was blown east as expected. However, winds in other areas blew the debris either north or west. This is likely due to the significant circulation with this supercell thunderstorm and the varying inflows and outflows. It was reported in Weskan that the winds gusted around 60 mph from the south just prior to the storm, shifting to the northwest at around 80 mph as the storm arrived.
