# Good rainfall in Brazil and dry weather in Argentina will be the main factors influencing prices in the coming weeks

> Heavy rain fell across most of Brazil, including the drier south, improving soybean and corn crops, with more rain forecast for the soybean belt. Central and southern Argentina remain drier and hotter, which increases crop stress as Midwest U.S. winter wheat faces colder weather.
