OMAHA (DTN) -- A weekend of have and have-not rain in Argentina, and possible cold-weather stress in the forecast for southern Plains wheat areas, are the key weather items for the commodity trade's attention Monday.
VARIABLE ARGENTINA RAIN
The DTN ag weather forecast calls for highly variable rainfall in Argentina's crop areas this week. The past weekend saw beneficial rainfall in eastern portions, but very little in the west. Similar variability is indicated in follow-up rainfall forecasts this week.
FAVORABLE CENTRAL BRAZIL PATTERN
Central Brazil has, again, consistent showers through the next week. This regularly occurring precipitation keeps crop conditions favorable with prospects for a big crop this season.
MIXED SOUTHERN BRAZIL FORECAST
Southern Brazil saw very little rain during the past weekend. Some beneficial showers and milder temperatures are expected this week. However, the far southern state of Rio Grande do Sul appears to miss out on the expected rainfall.
VARIABLE MIDWEST PRECIPITATION
In the Midwest, moderate to heavy rain is in store for the Ohio Valley during the next five days, with heavy rain farther south in the Delta. This helps recharge soil moisture for soft red winter wheat. Some ice and snow are also possible, which would affect transportation and travel. Elsewhere in the Midwest, northern areas have a chance at measurable snow, with dry and cold conditions otherwise in the next week to 10 days.
MUCH COLDER FOR NORTHERN PLAINS
A strong push of cold Arctic air is in store for the Northern Plains later this week and continuing through next week. This may be preceded by snow and blowing snow Wednesday.
DRYNESS INCREASES IN SOUTHERN PLAINS
In the Southern Plains, a warm and dry pattern continues to stress non-dormant winter wheat. Little precipitation is expected during the next 10 days. Much colder conditions are expected during the six- to 10-day period, which should put all of the crop into dormancy. However, this colder pattern will also cause some potential stress to wheat from the rapid change in temperatures.
A round of showers is indicated for Australia's eastern wheat belt, causing some brief disruption in late-stage harvest. Interruption is not expected to be significant.
BENEFICIAL SOUTH AFRICA TREND
Conditions remain beneficial for developing maize in South Africa.
