Chicago, Kansas and Minneapolis wheat all fell on May 6, while Chicago corn rose slightly. Excessive moisture persists across the Spring and Soft Red Winter wheat and corn belts, with more rain and cold temperatures forecast through mid-May.
Heavy rain is also forecast for Texas, where most of the wheat crop is heading and faces quality risk.
Wet weather delays corn planting and threatens wheat quality and yield, which supports corn prices and raises the risk of a national yield loss.
