Market Impact Weather

OMAHA (DTN) -- A wide variety of stressful conditions across the Midwest, and crop-threatening heat and drought in the Central and Southern Plains, are the key weather items for the commodity trade's attention Wednesday.

VARIABLE MIDWEST STRESS

The DTN ag weather forecast calls for variable stress conditions across the Midwest. Limited rainfall and above normal temperatures over central and southern portions of the western Midwest this week will increase stress to corn and soybeans, especially pollinating corn. Some crop losses can be expected. Northern Iowa and southern Minnesota should experience beneficial rainfall and more moderate temperatures. Mostly adequate to surplus soil moisture for crops is noted in the eastern Midwest. Hot weather will increase stress to reproductive crops over central and south Illinois and south Indiana during the next five days. Meanwhile, wet conditions, due mostly to prior rains, remain unfavorable for crops in parts of Indiana and Ohio.

VERY HOT IN SOUTHERN PLAINS

Southern Plains crop areas will likely remain hot, with only isolated showers in the next five days. This hot and dry trend will be increasingly stressful to reproductive crops during the next five days. Scattered showers and cooler weather should ease stress to crops for a time early in the six-to-10 day period, but additional episodes of heat are likely after that.

DROUGHT REMAINS OVER NORTHERN PLAINS

Episodes of hot weather and limited rainfall are expected to continue to significantly stress Northern Plains crops. Major losses to spring wheat have already occurred. Pollinating corn is now being affected with significant losses likely. The areas with most impact will likely be Montana, western and central North Dakota and South Dakota.

SOUTHERN PRAIRIES DRYNESS

In the Canadian Prairies, dryness is still of much concern in an area centered on southwest and central Saskatchewan. Showers during the next five days are expected to occur mostly north and east of this area.

DRY UKRAINE AND RUSSIA TREND

East Ukraine and southern Russia may see mostly above normal temperatures with little rainfall during the next five to seven days. The area's soil moisture is currently adequate, but will decline because of this weather pattern and the high moisture needs of crops. Scattered showers develop in western Ukraine growing areas, especially later in this period.

VARIABLE NORTHEASTERN CHINA RAIN

Northeastern China temperatures averaged above normal again Tuesday. Rainfall during the coming days appears more likely for key corn areas than in the key soybean belt in Heilongjiang province. Prior rains should support favorable develop of crops in or near reproduction through central and east areas while stress to crops remains high in the western areas where it is drier and where it trends toward hotter weather.

AUSTRALIA WHEAT DRYNESS

Dryness continues to be of concern through key growing areas of Australia. Showers have occurred during the past week in wheat areas of Western Australia, southeastern South Australia, Victoria and southeastern Queensland. Important wheat areas of New South Wales remained dry during this period. More rain is needed in all areas, even the locations that had showers during the past seven days after a very-dry June.
