Market Impact Weather

OMAHA (DTN) -- Heat continuing to stress crops in parts of Argentina, and continued favorable conditions in Brazil, are the key weather items for the commodity trade's attention Tuesday.

STRESSFUL ARGENTINA HEAT

The DTN ag weather forecast calls for the main Argentina corn and soybean areas of Cordoba, Santa Fe and northern Buenos Aires to continue under a variable pattern. Periods of hot weather increase the risk to reproductive crops, especially during the next few days. Showers at the end of the week will help to ease stress and improve moisture somewhat.

The main sunflower region and minor corn and soybean areas of La Pampa and southern Buenos Aires continue under a more extreme weather pattern. Longer periods of hotter weather and shorter periods of lighter showers means increased stress to these crops and a likely reduction in yield potential, especially any for reproductive crops at this time.

ADDITIONAL FAVORABLE CENTRAL BRAZIL TREND

In central Brazil, favorable conditions for developing soybeans continue.

GENERALLY FAVORABLE SOUTHERN BRAZIL

In southern Brazil, the weather pattern remains favorable in Parana and Mato Grosso do Sul at this time. In Rio Grande do Sul, crops should have adequate to somewhat short moisture for current needs. More rain would be welcome. A storm system expected in RGDS this coming Sunday is of the type than can bring better rains to the area. However, coming at day six of the forecast and with recent trends, such amounts are uncertain. The system still bears close watching.

MILD BUT DRY IN SOUTHERN PLAINS

Southern Plains conditions appear more favorable for winter wheat in the next 10 days, with no significant cold outbreak indicated. The trend is still dry, however. Meanwhile, the milder weather trend will also favor livestock.

COLD FOR MIDWEST

The Midwest continues in line for warm to very warm weather through Wednesday. Much colder conditions are in store for the end of the week. Precipitation chances feature rain changing to snow later this week with a possible snowstorm. Cold weather follows.

POSSIBLE NORTHERN PLAINS SNOWSTORM

In the Northern Plains, one more day of warm conditions is in store Tuesday. The trend changes to a much colder regime Wednesday night into Thursday. Colder and windy conditions are likely during Thursday with blowing snow possible. The new round of winter storm conditions will increase stress to livestock and increase risk of transportation delays in southern Minnesota, northwest Iowa and possibly southeast South Dakota.

STRESSFUL SOUTH AFRICA HEAT

South Africa was hot and dry during the past weekend. Highs of 95 to 100 Fahrenheit (35 to 38 Celsius) have been reported with some places locally hotter. The heat was stressful to developing maize and likely will reduce the yield potential for any reproductive maize. The high temperatures Monday were not as high as during the weekend, but still in an 88-to-96 F (31-to-36 C) range.
