The Weather Front On-Line

The Weather Front On-Line

A change in weather underway across the Midwest

Across the Corn Belt, a chilly rain is falling from Michigan to southeastern Nebraska. Showers are also spreading into the Ohio Valley, where warm, humid weather prevails. In contrast, cool, dry weather covers the far upper Midwest, where Frost and Freeze Advisories were are in effect early Tuesday in North Dakota and northern Minnesota.

A warming trend ahead for the Corn Belt

Across the Corn Belt, dry weather accompanies a warming trend, promoting corn and soybean maturation. On September 13, Illinois led the Midwest in corn development, with 61% of the crop fully mature.

Late-summer warmth promotes corn and soybean maturation.

Across the Corn Belt, late-summer warmth is promoting corn and soybean maturation. By August 30, nearly one-tenth (9%) of the U.S. corn was fully mature, with Midwestern maturity ranging from 0% in Michigan and North Dakota to 21% in Illinois. Although most of the Corn Belt is experiencing dry weather, locally heavy rain occurred Tuesday morning in east-central Illinois.

Late-Summer heat to expand across the Corn Belt

Across the Corn Belt, locally heavy showers over western and central portions of the region are further benefiting immature corn and soybeans while easing soil moisture shortages across northeastern Iowa and environs.

A favorable weather pattern for the Heartland

Across the Corn Belt, cool, dry weather prevails. Tuesday morning’s temperatures fell to near 40° in parts of the far upper Midwest. Temperatures and moisture conditions remain mostly favorable for filling summer crops.

Favorable weather in most Corn Belt regions

Across the Corn Belt, cool, mostly dry weather prevails in the wake of a cold front’s passage. Clouds and a few showers linger, however, in the vicinity of the Great Lakes. Continuing a summer-long trend, temperatures remain nearly ideal for Midwestern corn and soybeans.

Temperatures to vary in the coming days

Across the Corn Belt, mild, mostly dry weather favors corn and soybean development. In the upper Midwest, recently ended rainfall provided a favorable boost in topsoil moisture for immature summer crops.

Beneficial rains for parts of the Corn Belt

Across the Corn Belt, several thunderstorm clusters are providing generally beneficial moisture for immature corn and soybeans. However, pockets of flash flooding are occurring in the upper Midwest. On August 16, prior to the current rain event, topsoil moisture was rated 41% very short to short in North Dakota and Wisconsin.

Heat expands across parts of the Heartland

Across the Corn Belt, hot weather is expanding into the upper Midwest, where Friday’s high temperatures will approach 95°. Meanwhile, scattered showers dot the central Corn Belt. From March 30 – August 9, Missouri had the fewest days suitable for fieldwork (55.8 of out 133 possible days).

A warm, late Summer pattern to persist in the Midwest

Across the Corn Belt, warm weather is returning to the upper Midwest, accompanied by isolated showers. Elsewhere, sunny weather favors a rapid corn and soybean development pace.

On the Plains, shower activity is limited to the Dakotas, where minor small grain harvest delays are occurring. Elsewhere, warm, dry weather is promoting crop growth but boosting irrigation demands.
