Weather & Harvest Updates
The USDA’s August 16 bulletin reports dry weather continuing in many regions particularly the Western Corn Belt, further depleting soil moisture necessary for developing crops. At the same time, widespread showers promoted favorable crop conditions in the Great Lakes and Southeast Regions. The warm dry weather has been favorable to grain maturation in the Northern Plains regions while fields further south continue to be stressed.
