Across the Corn Belt, a nearly stationary storm system centered over the upper Mississippi Valley continues to produce snow showers and strong winds. In fact, Blizzard Warnings have been expanded to cover much of the Dakotas due to low visibility in snow and blowing snow. In the storm-affected areas, conditions remain extremely stressful for livestock and difficult for rural travel. Friday’s Midwestern high temperatures will range from near 15°F in the central Dakotas to 40°F or higher in the lower Ohio Valley.
