March in Illinois ran 4-5 degrees warmer and 1-2 inches drier than normal, letting some fields be worked and planted by mid-March. A cold snap with below-freezing minimums was forecast for east-central Illinois, and NASS had not yet reported planted acreage as of March 30.
Early planting favors a normal crop calendar, but a freeze or wet spell after early planting could force replanting and trim yield expectations. The outlook is a modest supply risk for corn and soybeans.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
