Iowa climate experts expect a warmer and drier than average growing season for much of the upper Midwest, following a dry 2020 in which statewide precipitation was 6.2 inches below normal. The National Integrated Drought Information System classified 52 percent of Iowa as abnormally dry.
Expected dryness in Iowa, the largest corn-producing state, raises weather risk premium for the coming crop and could support corn and soybean prices if the outlook holds into summer.
