A powerful winter storm brought heavy snow and gusty winds to the region. The first part of the storm produced heavy snow on Dec 30. The main system moved across the Central Plains with additional snow and strong northwest winds on the plains on Dec 31. Snowfall ranged from six to 12 inches, with higher amounts across the northern Black Hills and portions of southwest and south central South Dakota. Northwest winds gusting to 50 mph produced blizzard conditions with visibilities near zero at times across much of the western and south central South Dakota plains on Dec 31. Interstate 90 was closed for nearly 24 hours from Rapid City across South Dakota to Sioux Falls. With temperatures near zero, wind chill readings were 20 to 35 below zero.
