Adverse weather may slow the harvest of Brazil's second corn crop (safrinha). LSEG analysts expect unusually high temperatures and heavy rain in southern Brazil over the next two weeks, with the far south getting 40-160 mm above normal.
Argentina's winter wheat areas are forecast to receive more favorable rainfall.
Harvest delays in southern Brazil could slow safrinha corn shipments and tighten near-term export availability, supporting corn prices. Better moisture in Argentina should help wheat crop development and limit wheat price support.
