The U.S. Drought Monitor now shows moisture stress in every top corn-growing state. Released Thursday, the map shows expanding and intensifying drought conditions in all 18 major corn states. Plymouth, Cherokee and Woodbury counties in Northwest Iowa are facing extreme drought and will likely not see relief any time soon.

Illinois drought conditions did see some relief as intensity diminished in size between July 12 and 19. Three to four inches of rain relieved soils in northern and southern parts of the state. In Nebraska, 18 counties are now classified as extreme drought conditions while 34% of the state remain in severe drought conditions. Intensity has expanded, leaving only 14% of the state free from moisture stress.
