MIDWEST U.S. - 1

According to the USDA Crop Progress report for the week ending August 9, 2026, the U.S. corn crop is rated 61% good toexcellent, unchanged from the prior week, with 25% fair and 14% poor to very poor, while soybeans slipped slightly to 62% good to excellent 28% fair and 10% poor to very poor. The soybean decline was primarily due to conditions in North Dakota and to a lesser degree Missouri and Wisconsin. Over the next week, moderate to heavy rain is expected across the Corn Belt, particularly benefiting Iowa and Illinois, with precipitation expanding farther west and north into the Dakotas especially the western Dakotas, which should help ease any residual dryness and support late reproductive development in both crops. Temperature departures from the ECMWF AIFS ensemble indicate near to above normal readings across much of the central and southern Midwest for the next 1 to 5 days with more moderate conditions farther north, transitioning toward generally near normal temperatures in the 6 to 10 day period, creating overall favorable conditions that should aid grain fill and pod development without excessive heat stress.
