The Weather Front On-Line (August 2018)

Summer warmth, periodic moisture to continue

Across the Corn Belt, clusters of thunderstorms in the upper Midwest are maintaining soggy conditions. Lowland flooding persists along several rivers in southern Wisconsin. Despite the cloudiness and showers, above-normal temperatures are maintaining an accelerated pace of Midwestern summer crop development. On August 26, one-tenth of the U.S.

More late-Summer warmth, additional rainfall ahead

Across the Corn Belt, markedly cooler air is overspreading the upper Midwest. Meanwhile, lingering, late-season heat is promoting summer crop maturation from the middle Mississippi Valley into the lower Great Lakes region. Locally heavy showers and thunderstorms are occurring near the boundary between cool and hot air.

A more typical late-Summer pattern to return

Across the Corn Belt, scattered showers from the Mississippi Valley westward are maintaining generally favorable growing conditions for summer crops. Even some of the driest areas of the southwestern Corn Belt have experienced recent improvements in topsoil moisture, although drought-stressed pastures have been slow to respond to rain and corn is largely mature.

A return to more typical Summer weather ahead

Across the Corn Belt, cool, dry weather follows a widespread rain event. Nationally, less than one-eighth of the corn (12%) and soybeans (11%) were rated in very poor to poor condition on August 19, but those numbers stood at 44 and 37%, respectively, in Missouri.

More rain ahead; cooler, less humid days to follow

Across the Corn Belt, mild, dry weather has returned to the upper Midwest. However, locally heavy showers and thunderstorms are occurring across the southern and eastern Corn Belt, generally benefiting summer crops and providing drought relief in Michigan and the southwestern Corn Belt.

Welcome rainfall for some; cooler days to come

Across the Corn Belt, showery weather is occurring across large sections of Illinois, Indiana, Iowa, and Missouri. The rain is especially beneficial for pastures and soybeans in drought-affected areas of the southwestern Corn Belt. On August 12, Missouri led the Midwest with pastures rated 76% very poor to poor.

Beneficial rains ahead for parts of the Midwest

Across the Corn Belt, showers are overspreading drought-affected areas in Missouri and environs. The rain is largely too late for corn but should benefit pastures and later-developing summer crops such as soybeans. On August 12, Missouri led the country in corn (45%) and soybeans (37%) rated in very poor to poor condition.

A seasonal weather pattern covers the Corn Belt

Across the Corn Belt, lingering showers are confined to the Ohio Valley and the lower Great Lakes region. Dry weather has returned to the southwestern Corn Belt, following early-week showers that provided some limited drought relief. Most of the remainder of the Midwest continues to experience mostly favorable growing conditions for summer crops, with only one-tenth of U.S.

Favorable conditions across much of the Midwest

Across the Corn Belt, scattered showers and thunderstorms are occurring along and northwest of a line from Michigan to Kansas. The rain is maintaining generally favorable growing conditions for Midwestern corn and soybeans, although pockets of drought persist in the southwestern Corn Belt.
