The Weather Front On-Line

The Weather Front On-Line

Quiet weather across the Corn Belt

Across the Corn Belt, a few light rain showers are mainly confined to the middle Missouri Valley. Elsewhere, dry weather and a slow warming trend are promoting summer crop maturation. On September 22, Midwestern corn maturity ranged from 17% in Minnesota to 57% in Missouri.

Welcome rains across parts of the Midwest

Across the Corn Belt, showers and thunderstorms extend along a cold front from the Great Lakes region into the middle Mississippi Valley. The rain is slowing initial harvest efforts but easing dry conditions and providing beneficial moisture in advance of winter wheat planting. Cooler air trails the front into the western Corn Belt.

Beneficial rains across parts of the Corn Belt

Across the Corn Belt, late-season warmth prevails in advance of a cold front stretching from Minnesota to Nebraska. Showers and thunderstorms are developing in the vicinity of the cold front—and also near a warm front draped across the northern and eastern Corn Belt—slowing early-season harvest activities but providing relief from recent heat and dryness.

Scattered rains return to the western Corn Belt

Across the Corn Belt, Frost Advisories were in effect early Tuesday in parts of Michigan and Wisconsin, primarily north of the major corn and soybean production areas. Meanwhile, scattered rain showers are spreading into Iowa and Missouri.

An active pattern ahead

Across the Corn Belt, scattered showers are confined to southernmost corn and soybean production areas. Elsewhere, cool, dry weather favors summer crop maturation. However, some immature corn and soybeans continue to suffer from a lack of soil moisture.

Heat, humidity to expand across the Corn Belt

Across the Corn Belt, showers and thunderstorms across are providing beneficial moisture for immature summer crops across the far upper Midwest, including North Dakota and parts of Minnesota. Across much of the remainder of the Midwest, however, persistent dryness and increasingly hot conditions are maintaining significant stress on pastures and immature corn and soybeans.

Heat wave continues on the Plains

Across the Corn Belt, mostly dry conditions are maintaining stress on immature corn and soybeans. In addition, heat is returning to the western Corn Belt, where Friday’s high temperatures will exceed 90°. In contrast, Friday’s highs will remain below 80° in Michigan and Ohio.

A change in weather ahead

A large area of high pressure aloft will continue to prevail over the central United States through the start of the Holiday Weekend. This will result more hot and humid weather over central Illinois, with highs in the lower 90s through Sunday. Then, a cold front is forecast to move through late Sunday, bringing a return to more seasonal temperatures for Labor Day.

Heat wave to expand across the Heartland

Across the Corn Belt, thunderstorms are affecting the Great Lakes region, including Wisconsin and Michigan. Elsewhere, hot, dry weather is increasing stress on corn and soybeans. Monday’s highs will generally range from 85 to 90° in the eastern Corn Belt, but will top 95° in some locations from the Mississippi Valley westward.
