The Weather Front On-Line

The Weather Front On-Line

Heat, humidity & storms ahead for the Corn Belt

Across the Corn Belt, locally heavy showers and thunderstorms are bringing renewed fieldwork delays, mainly west of the Mississippi River. In Missouri, only 30% of the intended soybean acreage had been planted by June 7, compared to the 5-year average of 69%. Farther east, hot weather prevails in the Ohio Valley.

Generally favorable weather throughout the Corn Belt

Across the Corn Belt, conditions remain mostly favorable for late-season planting. However, wet weather persists in the southwestern Corn Belt, where corn and soybean planting activities remain behind schedule.

Favorable weather returns to most of the Corn Belt

Across the Corn Belt, cool, mostly dry weather favors soybean planting and other late-spring fieldwork. However, showers are returning to the westernmost Corn Belt, including the Dakotas and Nebraska. Significant soybean seeding delays are limited to the southwestern Corn Belt, where Missouri’s planting was just 23% complete—compared to the 5-year average of 57%—by May 31.

A brief spell of drier weather

Across the Corn Belt, cool, dry weather prevails, except for some rain in the Ohio Valley. Frost Advisories were in effect Monday morning in the upper Great Lakes region—outside of the Corn Belt—from northeastern Minnesota to portions of northern Lower Michigan.

A change in weather ahead

In the Corn Belt, increasing shower activity in advance of a cold front is slowing fieldwork. Cooler air is already overspreading the upper Midwest, but warm, humid weather lingers across the eastern Corn Belt.

More rain on the soaked southern Plains

Across the Corn Belt, rain lingers in the Great Lakes region. Dry weather has returned to the remainder of the Midwest, although minor fieldwork delays persist. Among the Midwestern States, only Missouri reported a significant soybean planting delay (20% planted by May 24, vs. the 5-year average of 43%).

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.

An active pattern ahead

Across the Corn Belt, warm, mostly dry weather prevails between storms. However, showers linger across the Ohio Valley and the lower Great Lakes region in conjunction with a departing system, while rain is returning to parts of Nebraska in advance of an approaching storm.

More rain breaking-out on the southern Plains

Across the Corn Belt, frost advisories were in effect early Wednesday across much of Wisconsin, where 9% of the corn had emerged by May 10 and Wednesday morning’s temperatures locally fell below 32°. Elsewhere in the Midwest, cool, dry weather favors fieldwork but is slowing summer crop emergence and development.

Weekend storminess gradually shifts east

Across the Corn Belt, lingering warmth in the Ohio Valley and lower Great Lakes region contrasts with sharply cooler conditions west of the Mississippi River. In recent days, conditions for planting have been nearly ideal in the eastern Corn Belt. Currently, a band of showers stretches from Wisconsin to southeastern Missouri.
