The Weather Front On-Line

The Weather Front On-Line

A drier pattern for much of the Corn Belt

Across the Corn Belt, dry weather and near- to below-normal temperatures favor a gradual push toward maturity for late-developing corn and soybeans. By September 14, corn reaching maturity ranged from 15 to 25 percentage points behind the respective 5-year averages in Iowa, Minnesota, and the Dakotas.

Widespread rains across the Corn Belt

In the Corn Belt, rain is soaking the upper Mississippi Valley and the upper Great Lakes region. Sharply colder air is arriving in the far upper Midwest, where temperatures have fallen below 50°. Warmth lingers, however, from the Ohio Valley into the lower Great Lakes region.

A big change in weather ahead

Across the Corn Belt, locally heavy showers stretch from Michigan to Nebraska. Meanwhile, very warm weather across the southern and eastern Corn Belt is promoting corn and soybean maturation. On August 31, corn was 5% fully mature in Illinois, well behind the 5-year average of 24%.

Heat, humidity to briefly expand; more rain ahead

Across the Corn Belt, above-normal temperatures continue to benefit late-developing summer crops. On August 31, corn reaching the denting stage of development was 13 percentage points behind the respective 5-year state averages in Michigan, Minnesota, Pennsylvania, and Wisconsin—and 21 points behind average in North Dakota.

Periodic rains to continue across the Heartland

Across the Corn Belt, thunderstorms are rumbling across the Ohio Valley, while a separate area of showers is crossing the upper Mississippi Valley. Recent and ongoing Midwestern rainfall has generally benefited late-developing summer crops but has been excessive in a few areas.

Heat, humidity & periodic rains for the Holiday Weekend

Across the Corn Belt, showers are benefiting filling corn and soybeans in western and northern portions of the region. In contrast, dry, hot weather across the southern Corn Belt is hastening summer crop maturation.

More storms, building heat & humidity

Across the Corn Belt, showers and thunderstorms stretch from southern Iowa and northern Missouri eastward into parts of Ohio. The rain is benefiting pastures and immature summer crops.

Storm clusters, building heat for the Corn Belt

Across the Corn Belt, very warm weather is building into southern corn and soybean production areas, where Wednesday’s high temperatures will exceed 90°. Elsewhere, beneficial showers dot the eastern Corn Belt, while favorably warm weather is aiding late-developing summer crops in the upper Midwest.

Heat, humidity to build into the Corn Belt

Across the Corn Belt, scattered showers are most numerous in northern production areas, from North Dakota to Wisconsin. The rain is helping to ease the effects of short-term dryness that has developed in recent weeks. Nevertheless, overall conditions remain mostly favorable for Midwestern pastures and summer crops, in part due to this summer’s absence of stressful heat.

Cool weather continues across the Midwest

Across the Corn Belt, dry weather accompanies near- to below-normal temperatures. Conditions remain favorable for Midwestern pastures and summer crops, except in areas that have trended dry since early July and did not receive appreciable rainfall during a series of cold frontal passages from August 5-12.
