Across the Corn Belt, cloudy, breezy conditions and a few snow showers linger across the lower Great Lakes region. Elsewhere, cool, dry weather prevails. A Freeze Warning was in effect early Tuesday in much of the southern Corn Belt, from Missouri into the Ohio Valley. Midwestern soybean planting has not begun, while corn planting has been limited to Missouri (4% complete by April 17, versus the 5-year average of 13%) and Nebraska (2% complete, versus 2% on average).
