USDA Climate Hubs and partners released regional outlooks for the developing La Niña pattern, which is expected to bring below-normal temperatures to the upper Midwest and wetter conditions to the Ohio River Valley this winter. Impacts on agriculture include snowpack insulating crops and colder temperatures limiting some pests, while livestock producers may face higher operating costs.
La Niña winter patterns shape planting prospects and livestock costs in the US Midwest, which can support corn and feed grain prices if yield risk builds ahead of spring. The effect on prices is modest because the outlook is general and mostly benign for crops.
