DTN meteorologist John Baranick, writing August 31, 2025, says La Niña is likely to return in fall, especially late in the season, typically bringing a warmer, drier pattern to much of the US. He notes the southern and eastern Corn Belt were very dry in August and likely saw yield trimming, with intense drought in the West.
Dryness already trimming Corn Belt yields plus a drier outlook for winter wheat areas supports feed grain and wheat prices, though good harvest conditions limit the upside.
