Indiana state climatologist Ken Scheeringa explains why long-range forecasts have been inconsistent. A strong La Niña forecast for July did not verify, and forecasters now expect a weaker La Niña to return.
Some early signs of change were already visible, including drought in the southeastern US.
Uncertain long-range forecasts add weather risk premium for the coming growing season, but without a confirmed drought threat the effect on feed grain prices is limited.
