 As we look at South American weather in Brazil, cold air moved in behind the front this past weekend, causing some frost across the south. Despite the cold, there was not a likely effect on either winter wheat planting or maturing so free to corn. Now a front will move into the south late this week. It may stall in some areas going into next week. If it sticks around, flooding could be possible in some of those areas which have seen flooding here throughout the spring so far.
