Across the Corn Belt, a major, late-season winter storm is producing snow and freezing rain across the far upper Midwest, leading to blizzard conditions in much of South Dakota and environs. A sharp temperature gradient exists across the Midwest as the storm system crosses the western Corn Belt. For example, Friday’s high temperatures will remain near or below 32°F in the Dakotas—but will reach 70°F or higher as far north as the middle Mississippi Valley.
