A severe thunderstorm knocked out power to some, knocked over trees and disrupted a night of car racing in Huron. The storm traveled south from the Aberdeen area just east of US Highway 281. Golf ball-sized hail was reported three miles east, southeast of Wolsey. Winds of 60 miles an hour were reported four miles south southwest of Hitchcock. A wind gust of 70 miles an hour recorded at the Huron Regional Airport. Strong winds and law enforcement reported rotation prompted outdoor warning sirens in Huron to be sounded. That sent race fans at Dakota State Fair Speedway scrambling for safety under the grandstands. The National Weather Service received two tornado reports. A report at 8:14 pm said a tornado was in Wolsey. Ten minutes later, the Weather Service says a tornado was reported near Virgil. Northwestern Energy reported power out in Hitchcock and Tulare. East River Electric Power Cooperative says high voltage power lines on their system in the Bonilla area were damaged by the storm. Fifteen transmission poles over a one-mile stretched were damaged causing around 1300 customers to be affected. Power was restored by nine-P-M. Other damage was reported seven miles north northwest of Loomis and eight miles southwest of Letcher where a trailer home rolled over in the wind. Damage near Loomis included a small outbuilding being destroyed along with shingle and window damage. Tree damage was reported in Woonsocket. No damage has been confirmed from the tornado reports in Beadle County.
