The Weather Front On-Line (August 2012)

Heavy weekend rains ahead for much of the central, southern Corn Belt

Across the Corn Belt, hot, dry weather is promoting summer crop maturation and early-season harvest activities, but is maintaining stress on drought-affected pastures.

On the Plains, hot, dry weather favors summer crop maturation and fieldwork, including winter wheat planting preparations.


"Big" rains ahead for parts of the central, southern Corn Belt

Across the Corn Belt, mostly dry weather accompanies a late-season warm spell. Scattered showers are confined to the upper Midwest. On August 26, Missouri led the nation with 99% of its pastureland rated in very poor to poor condition, followed by Nebraska with 95%.


Rain chances increase for the balance of the weekend

Dry weather continues Saturday, with temperatures remaining above normal. Afternoon highs will reach the lower 90s.  Overnight lows will settle through the 60s.  A weather system will arrive by Sunday, bringing with it occasional outbreaks of scattered showers and thunderstorms through Monday.  Highs into early next week will return to the 80s.


Late-season heat across much of the Corn Belt

Across the Corn Belt, isolated showers are confined to the upper Midwest. Elsewhere, late-season heat is bringing renewed stress to pastures and immature summer crops, following a 2-week period of favorably cooler weather.

On the Plains, beneficial but widely scattered showers continue across roughly the southern half of the region.


Topsoil moisture improves slightly across the state

Cooler temperatures and several showers across much of the state last week were a welcomed change from the hot and dry conditions experienced throughout the summer thus far.


Recent rains modestly improve late-season crop conditions

Across the Corn Belt, mild, mostly dry weather prevails. During the week ending August 19, soybeans rated very poor to poor fell (improved)—on the strength of cooler weather and recent rainfall—five percentage points in Indiana, Michigan, and South Dakota. Even with the improvement, more than one-third (37%) of the U.S.


Recent rains benefit much of the central Corn Belt

Across the Corn Belt, cool, dry weather prevails. Pastures and some soybeans continue to benefit from the recent turn toward cooler weather, as well as last week’s scattered showers—which were heaviest in the central Corn Belt.

On the Plains, hot, weather has returned to Montana, while mild, dry weather covers the remainder of the region.


Topsoil moisture still very short in the wake of recent rains

Across the Corn Belt, topsoil moisture was rated mostly very short to short in Missouri (99% very short to short), Nebraska (96%), Illinois (95%), and Iowa (91%).

On the Plains, topsoil moisture remains at critically low levels across most of the region—with very short to short ratings dominating in Oklahoma (98% very short to short), Kansas (96%), and Nebraska (96%).

In the South


A pleasant change in weather ahead for the Midwest, Plains

Across the Corn Belt, cooler-than-normal weather prevails. Showers are exiting the eastern Corn Belt but returning to westernmost portions of the region. The recent turn toward cooler, wetter weather continues to benefit pastures and some soybeans.


Half the U.S. corn crop rated poor to very poor

Across the Corn Belt, heat is temporarily building back across southern portions of the region in advance of a cold front. In addition, unfavorably dry weather has returned, following last week’s beneficial showers. During the week ending August 5, half (50%) of the U.S. corn was rated very poor to poor, along with 39% of the U.S. soybeans.
