Another winter storm is moving through southern Minnesota, and a Winter Storm Warning is in effect. The New Ulm area received nearly 3 inches of snow overnight, and Meteorologist Greg Tatro says that more snow is on the way. He says that the main system is still developing and strengthening to our west through this afternoon, and another 1-3 inches of snow is possible tonight. On Tuesday a dusting up to an inch of snow is possible as well. Some areas of southern Minnesota could possibly see up to 15-inches of new snow by the time the storm passes through. The Winter Storm Warning is in effect until Noon on Tuesday.
