Meteorologist Eric Snodgrass says a small shift in the summer ridge explains why 2017 produced record corn yields rather than drought. He notes that a delay in Brazil's rains pushed back planting of the safrinha corn crop by about a month.
He expects a wetter, more active storm track in the Corn Belt this winter.
Brazil's delayed safrinha planting raises the risk of lower second-crop corn output, which could support export corn prices later in the marketing year. The US weather outlook has less direct price effect.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
