Iowa State Integrated Crop Management summarizes NOAA's November and winter 2021-22 outlooks. November shows equal chances for Iowa, while winter shows a classic La Niña pattern with colder conditions from Minnesota northwest and drier conditions across the southern US.
Cold, dry winter forecasts for the northern and southern Plains could affect winter wheat dormancy and the 2022 crop outlook, though the signal for Iowa is weak and gives limited price direction.
