The Weather Front On-Line

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.


Late-season Heat wave to build across the Heartland

Across the Corn Belt, mostly dry weather has returned, following yesterday’s beneficial showers. Friday’s high temperatures will remain below 80° in much of the Great Lakes region.


Heat building across the Corn Belt

Across the Corn Belt, heat continues to arrive from the north and west. Tuesday’s high temperatures will exceed 90° in the western-most Corn Belt, fostering the development of late-planted corn and soybeans.


Warmth returning to the Corn Belt

Across the Corn Belt, isolated showers are confined to the upper Mississippi Valley. Midwestern soil moisture continues to gradually diminish, with the most acute shortages noted across Iowa (excluding the northeast), northern Missouri, and neighboring areas.


Soil moisture lacking in the western Corn Belt

Across the Corn Belt, scattered showers and thunderstorms precede and accompany a cold front’s passage. Cool weather is returning to the upper Midwest, but warmth lingers in the Ohio Valley. Portions of the region, especially across the western Corn Belt, still have limited soil moisture for corn and soybean development.


A wide-range of weather across the Heartland

Across the Corn Belt, cool weather continues to benefit reproductive to filling summer crops. Showers in the western Corn Belt are easing concerns over short-term dryness.


More cool weather ahead for the Corn Belt

Across the Corn Belt, a broken band of shower activity stretches from the Great Lakes region into the lower Missouri Valley. The rain is providing some relief from short-term dryness in the southwestern Corn Belt. Cool air trails the showers into the upper Midwest, where Friday’s lows ranged from 50 to 60°.


Generally favorable conditions for midwestern Corn and Soybeans

Across the Corn Belt, scattered showers and thunderstorms are maintaining generally favorable conditions for corn and soybeans. However, short-term dryness is increasing stress on reproductive summer crops in some areas, including much of Iowa, northern parts of Illinois and Missouri, and eastern Nebraska.


More heat & humidity across the Corn Belt

Across the Corn Belt, an approaching cold front is generating scattered showers and thunderstorms. Shower activity is most significant in the Great Lakes region. In advance of the storminess, heat and short-term rainfall deficits are maintaining stress on reproductive corn and soybeans in the southwestern Corn Belt.


More heat, humidity throughout the Heartland

Across the Corn Belt, Heat Advisories remain in effect for the combination of hot weather and high humidity. Thursday’s high temperatures will again range from 90 to 95° in many areas, except 95 to 100° in parts of the western Corn Belt.
