A monster winter storm is taking aim at the Upper Midwest, threatening to bring blizzard conditions, bitterly cold temperatures and 2 feet of snow in a three-day onslaught that could affect more than 40 million Americans. The storm is set to begin around midday Tuesday (2/21/23) and continue through Thursday morning (2/23/23), dumping heavy snow over parts of the Dakotas, Nebraska, Minnesota, Iowa and Wisconsin. More than a foot of snow is possible in Sioux Falls and Rapid City, South Dakota. The Northern Black Hills of South Dakota (including Lead and Deadwood) could possibly see 18-24 inches of snow.
