 As we look at South American weather in Brazil, cold air moved in behind a front this weekend, causing frost across the south. Despite the cold, there was not a likely effect on either winter wheat planting or maturing of Safrida corn. A front will move into the south late this week. It may stall in some areas going into next week, and it could bring some more rain potential. In Argentina, rainfall deficits continue to build up, but soil moisture is low for winter wheat establishment in most of the country. That's agricultural weather here on the American Ag Network.
