NOAA's Drought.gov outlook dated September 8, 2025 explains ENSO phases and their typical US precipitation and temperature effects. It states La Niña is likely from September 2025 through January 2026 with greater than 50% probability, suggesting drought persistence in the Southwest and potential development in the Southeast.
A likely La Niña raises the risk of dryness in the southern US Plains and Southeast during winter, which can affect winter wheat and sorghum prospects and support feed grain prices.
