November 29, 2010 Heavy Snow over the Northern Black Hills

Heavy snow blanketed the northern Black Hills and foothills.  Twenty to thirty inches fell over the higher terrain, with six to fifteen inches covering the foothills around Spearfish. Snowfall on the plains ranged from less than an inch to six inches, but strong winds blew the snow and caused low visibilities. The National Weather Service near downtown Rapid City recorded a peak wind gust of 62 mph and the Rapid City Regional Airport had a gust of 60 mph.  Snow and wind reports from across the region:
