MIDWEST U.S. - 1

Across the Corn Belt from today through the next one to two weeks additional rainfall is expected to focus more heavily on the western areas including Iowa Nebraska and parts of Minnesota keeping fields soggy and slowing corn harvest progress where only limited acreage has been combined so far while eastern sections such as Illinois Indiana and Ohio should see lighter amounts allowing better field access and steadier combining of mature corn that already stands ahead of average nationally at thirteen percent harvested overall. Cooler temperatures will accompany the midweek rain chances before a brief warmer and drier stretch arrives later in the period supporting improved drying and fieldwork once western soils firm up though farmers in the wetter zones will need to watch for higher grain moisture and possible delays until conditions improve.
