A cluster of storms initially generated hail mainly to the size of quarters across portions of central South Dakota, then organized into a line and increased speed. This resulted in high winds across northeast South Dakota during the late evening and early overnight hours. A peak wind gust of 90 mph was recorded by the South Dakota Department of Transportation (SDDOT) mesonet station 4 miles north of Altamont, with a 78 mph wind gust recorded on a personal weather station 9 miles northwest of Aberdeen, 77 mph on a personal weather station in Faulkton and a 74 mph gust at the SDDOT station near Ree Heights (Hand County).

Intermittent wind damage was reported across much of northeast South Dakota, with reports of peeled roofs and lost tiles, blown in garages and trees down. In the city of Aberdeen and surrounding area, several of these trees landed on vehicles. The Aberdeen City Forester reported the cost for just tree cleanup on city property (including boulevards) topped out at $14,585.
