A heat wave across the Northern and Central Plains brought little rainfall, adding to dry conditions in parts of the Corn Belt. NASA data show extremely below-normal soil moisture in the Dakotas, Nebraska, Minnesota, western Iowa, and Wisconsin, alongside modest declines in crop conditions.
Persistently dry soils could stress crops and reduce yield potential, tightening U.S. corn and soybean supplies and supporting prices if the dryness continues.
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.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
