The National Weather Service forecast for June 1-5 calls for above-normal precip for most of Iowa eastward and from Nebraska southward. If realized, areas of the eastern Corn Belt will face planting delays, raising the risk of some corn acres shifting to soybeans. The best chance for above-normal precip is across Texas, which if realized raises concerns about the quality of the HRW wheat crop as harvest should begin very soon.
Temperatures during the period are expected to be cooler-than-normal from Nebraska southward and warmer-than-normal from Indiana eastward. Minnesota, Iowa, Wisconsin the Dakotas and Illinois are expected to see normal temps.
