Meteorologist Drew Lerner argues that a negative Pacific Decadal Oscillation combined with La Niña could push North America's drought eastward this summer while bringing wetter conditions to Canada and the northern Plains. The piece is a seasonal weather outlook rather than a new observed event.
A drought spreading into the central US Corn Belt would be a major upside risk for corn and soybean prices, though the forecast is speculative for now.
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.
