The National Weather Service issued winter storm warnings for a long swath stretching across the Upper Midwest from North Dakota and northwestern Minnesota, then southeastward into western and southern Wisconsin, northeastern Iowa, northern Illinois, northern Indiana and into western and central Ohio.
