| Episode Narrative | A strong storm system moved across the Rockies and Northern Plains, bringing heavy snow to western and south central South Dakota. Snowfall amounts were in the six to 12 inch range, with as much as 18 inches from northwestern into west central South Dakota. Northwest winds of 15 to 30 mph produced areas of blowing snow and greatly reduced visibilities at times. Interstate 90 east of Rapid City was closed during the overnight hours. |
