|Brief Description: A significant tornado (rated F2 based on damage survey) touched down 8 miles SW of Hill City near Road 220 and Road J at approximately 4:20 pm CDT. As the tornado continued northeast toward Road 260 and Road M it damaged two homes and destroyed a detached garage. One home suffered roof damage while another had part of the roof from the upper story removed. Significant and continuous tree and power pole damage was noted for one mile south of this location. Some of this damage was likely produced by an intense rear-flank downdraft accompanying the southern periphery of the tornado. As the tornado crossed Highway 283 approximately 3.5 miles south of Hill City, it caused structural damage to a hangar used as storage. A boat, a small four-wheeler and a camper were either heavily damaged or destroyed, with debris rolled or bounced between one-half and three-fourths of a mile. The tornado crossed the intersection of Road 290 and Road O producing tree damage. The tornado ultimately lifted about a half mile northeast of this location at approximately 4:48 pm CDT.|
