Frost, freeze parts of the Dakotas, upper Midwest
Across the Corn Belt, light freezes were noted Tuesday morning in parts of Minnesota and northern Wisconsin, possibly burning back some new corn growth. Nearly three-quarters (72%) of Minnesota’s corn had emerged by May 17. Farther east, cool, dry weather favors a gradual return to fieldwork in the central and eastern Corn Belt.
On the Plains, Freeze Warnings were in effect early Tuesday across much of the Dakotas. Bismarck, North Dakota, reported a daily-record low temperature of 25°. In some areas, freezes may have burned back corn growth, which on May 17 was 12% emerged in North Dakota and 46% emerged in South Dakota. Farther south, heavy rain returned overnight to portions of the central and southern Plains, causing some flash flooding.
In the South, warm, humid weather accompanies widely scattered showers. Lowland flooding lingers in a few areas from the western Gulf Coast northeastward into Arkansas.
In the West, warm weather remains primarily confined to Washington. Elsewhere, cool weather is slowing crop development but reducing irrigation requirements. Widespread showers across the northern Intermountain West are boosting soil moisture for winter wheat and spring-sown crops, while some late-season snow is falling in the central Rockies.
