OMAHA (DTN) -- Variable effects from persistent rain in central Brazil, and a drier trend in Argentina, are the key weather items for the commodity trade's attention Tuesday.
WESTERN MIDWEST SNOW
The DTN ag weather forecast calls for a round of snow with some freezing precipitation in the western Midwest during the Tuesday-Wednesday time frame. The focus of this wintry precipitation will be in northern Iowa through Minnesota. Transportation will be disrupted, and some livestock stress may occur. Elsewhere, there are no major issues through this last full week of January.
WINDY AND DRIER IN SOUTHERN PLAINS
In the Southern Plains, recent very significant precipitation will recharge soil moisture for wheat. However, a drier pattern with very warm weather and strong winds will lead to some evaporation of this moisture during Tuesday, and put the wheat crop into a position of needing additional precipitation to maintain the improved prospect later this spring.

NORTHERN PLAINS SNOW
In the Northern Plains, moderate to heavy snow during the next two days will affect travel and transport, especially in Nebraska and South Dakota during Tuesday. Improving conditions are indicated from Wednesday on.
MIXED BRAZIL RAIN EFFECT
Scattered thunderstorms in central Brazil crop areas may improve the outlook for second crop corn, but the rain will also delay the harvest of early soybeans and early corn. Mostly favorable conditions are in effect for crops in southern Brazil at this time, despite a drier trend in Rio Grande do Sul.
ARGENTINA HEAT AND DRYNESS
Argentina's northern and central crop areas continue with a drier pattern and very warm to locally hot weather during the balance of this week. This will favor developing corn and soybeans in Cordoba, Santa Fe and northern Buenos Aires after recent heavy rains and flooding, at least for a while. Extreme heat that occurred in southern Buenos Aires and La Pampa early this weekend ended with a few strong storms later in the weekend. Another round of heat/dryness is expected this week. This will maintain high stress and reduce crop yield prospects for La Pampa, west and south Buenos Aires.
DECREASING UKRAINE SNOW COVER
Southern and eastern Ukraine wheat areas have had a decreasing amount of snow cover. Low temperatures near zero Fahrenheit (minus 17 Celsius) forecast this week leave crops in these areas at a higher risk from cold damage.
