Kansas State's Agronomy eUpdate says excess moisture has dominated the first half of May, with eastern Kansas already above normal May rainfall. The June outlook favors wetter and cooler conditions across the Central Plains.
Saturated soils and poor root development are flagged as concerns for spring-seeded crops.
Wet, cool conditions in the Plains delay planting and may reduce yields for wheat, corn and sorghum, supporting prices. Feed buyers face possible tighter supplies of US feed grains if the outlook holds.
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 1,072 past bullish weather events, Wheat (SRW) moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
After 322 past bullish weather events, Wheat (HRW) moved a median -0.1% over 5 sessions (49% higher; middle half -2.5% to +3.2%), and +1.0% over 20.
