On Friday afternoon, much of the Northern Black Hills was hit by a severe thunder storm, which brought hail, strong winds, heavy rain, and even tornadoes and flooding to the area. According to the Black Hills Pioneer, winds near Belle Fourche were measured at over 70 miles per hour and caused a travel trailer to be blown over on the highway.
Tornadoes were recorded north of Belle Fourche and south of Lead in Spearfish Canyon. Trees and power lines were downed west of Cheyenne Crossing. Many communities in the Northern Hills reported heavy rains and golf-ball sized hail. The National Weather Service plans to survey damage from the tornado in Spearfish Canyon Tuesday.
The Rapid City Journal reports that nine other tornadoes were also reported Thursday night in Southeast Montana and Northwest South Dakota. Several buildings and pieces of farm equipment were damaged by the storms.
