OMAHA (DTN) -- Midwest heat stress leading to reduced harvest prospects and the prospect of heavy rain from Hurricane Laura are the key weather items for the commodity trade's attention Wednesday.

MORE MIDWEST HEAT STRESS

The DTN ag weather forecast calls for mainly hot and dry conditions across the Midwest again Wednesday, with more stress to row crops and concerns about yield reduction at harvest. The pattern turns seasonal on temperatures as a front slips southward through the region and likely be aided by tropical moisture from the remnants of Hurricane Laura. Heavy moisture could make its way north of the I-80 corridor, but models are mixed on if that will include Iowa or not. A two-part frontal system will move through early next week with more widespread rainfall.

MIXED SOUTHERN PLAINS SHOWERS

In the Southern Plains, periods of scattered showers are indicated during the next five days for most areas except western Texas. Some southeast sectors could see locally heavy rain due to Hurricane Laura. Temperatures continue to show a seasonal to above-normal trend through the balance of the week.

NORTHERN PLAINS STORMS

Northern Plains crop areas have shower and thunderstorms through the next five days. Rain and storms will disrupt spring wheat harvest and will threaten crop quality.

DELTA HURRICANE WATCH

In the Delta and Southeast, remnants of Hurricane Laura may bring heavy precipitation and flooding to the Delta. The projected track is west of the Delta, but heavy rain could still form in the region. Open boll cotton may be damaged and early row crop harvest disruptions may develop. The Southeast has a drier trend in store.

STORMY PRAIRIES PATTERN

An active storm track is indicated for the next week in the Canadian Prairies. A strong storm this weekend into early next week will likely cause widespread rainfall, strong winds, and falling temperatures into next week.

DRY CENTRAL BRAZIL TREND

Central Brazil crop areas have a dry pattern in store for the next seven days. This trend will be closely watched for possible change ahead of mid-September. The mid-September period is the official starting date for the beginning of soybean planting.

LIGHT RAIN FOR ARGENTINA

Most Argentina crop areas have short to very short soil moisture supplies. Light rain over the next five days will bring very little improvement.

POSSIBLE EUROPE SHOWERS

Across Europe, scattered showers will continue into the southeast, with beneficial conditions for filling crops. Showers are also indicated through the balance of the week across the continent.

SCATTERED BLACK SEA RAINFALL

In the Black Sea region, drier areas from central Ukraine through southern Russia will be mostly dry this week until a storm system finally moves through with scattered showers late this week. Harvest activities will benefit while filling corn and sunflowers will continue to show stress in many areas.

VARIABLE AUSTRALIA SHOWERS

Australia wheat areas have scattered light rain showers indicated through the rest of the week. Queensland is still in a drier pattern. Other wheat areas have adequate soil moisture.
