Sioux Falls, S.D. – Scattered severe storms could develop across much of South Dakota Friday evening and persist into the overnight hours, bringing threats of damaging winds, large hail, and heavy rain. The National Weather Service warns that wind gusts could reach 70 mph, with hail up to the size of a half dollar possible in the strongest cells.
According to the National Weather Service in Sioux Falls, storms are most likely to form over central South Dakota after 10 p.m. before tracking east toward the I-90 corridor and into southwestern Minnesota. The highest risk for severe weather will be north of I-90, where localized flooding in low-lying areas and urban streets is possible.
Residents are urged to secure outdoor items, have multiple ways to receive warnings, and be prepared to take shelter if a warning is issued. Drivers should use caution, as sudden downpours could reduce visibility and cause water to pool on roadways.
Warnings remain in effect through early Saturday, with a separate Heat Advisory in place for much of the region Saturday afternoon, pushing heat index values over 105°F in some areas.
