A large system brings widespread rain to the US Midwest through Wednesday, pausing fieldwork, while showers cross the Central and Southern Plains and Northern Plains. Central Brazil is seeing below-normal rainfall and southern Brazil heavy rain, which are also driving markets.
Harvest delays slow corn and soybean deliveries in the short term, while rain may ease drought for winter wheat; Brazil's dry central region and wet south bear on the South American crop outlook and soybean and corn prices.
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, SOY moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
After 224 past neutral weather events, WHEAT moved a median -0.1% over 5 sessions (46% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
