A several minute period of severe thunderstorm winds with a peak gust of 61 mph was measured by a Road Weather Information System site 13 miles west of Ward.

Wider weather episode

A strong upper level wave moved from the northern Rockies into southern Canada, brushing through eastern South Dakota and stirring up a 35-45 knot low-level jet within an environment with around 2000 J/kg of elevated MUCAPE. By evening, a well-organized convective system developed across northeast South Dakota and dropped slowly southeast through the overnight hours. Along the track, stronger cells produced large hail up to golf ball size and scattered wind damage.
