A low pressure system deepened while it tracked from the Dakotas on the 10th into Minnesota and Wisconsin by the morning of the 11th, and then further deepened as it stalled through the 12th. This system generated high wind gusts of 50 to 70 mph across central, north central and northeast South Dakota on the 11th and 12th; the strongest measured gust was 70 mph at Hayes, SD. Several high-profile vehicles were tipped as a result, with at least 10 between Kadoka and Murdo on Interstate 90.
