Across the Corn Belt, the most significant winter storm of the season is well underway. Hazards, including heavy snow and blowing snow, stretch from southeastern Nebraska to near Lake Michigan, leading to travel disruptions and increased livestock stress. In contrast, mild weather lingers in the eastern Corn Belt, with rain falling early today in the Ohio Valley and neighboring areas. Elsewhere, cold air is settling across the far upper Midwest; Tuesday morning’s low temperatures fell below 0°F in parts of the Red River Valley of the North.
