Winter Storm in Hermosa Foothills, South Dakota

A very strong winter storm moved across the region, bringing heavy snow and blizzard conditions to much of western and south central South Dakota. Snow developed during the morning hours, with rain and snow changing to snow southeast of the Black Hills by the early afternoon. Northwest winds increased during the late morning and afternoon, with blizzard conditions developing across much of the plains. Snow ended the next morning, with winds gradually tapering off by late afternoon. Snowfall amounts were widely variable across the area, ranging from an inch or less over parts of Harding County to one to two feet in some portions of Haakon, Jackson, and Bennett Counties and portions of the northern Black Hills. Drifts of six feet and higher were reported where the heaviest snow fell on the plains. Much of Interstate 90 across western South Dakota were closed for more than 36 hours.
