Climatempo forecasts rain across Rio Grande do Sul, Santa Catarina and Paraná on Sunday, with storms and hail risk, especially in northern and western Rio Grande do Sul. Storms are also expected across the Center-West and Southeast, hitting areas with soybean planting, early corn germination and the final stretch of the wheat harvest.
Hail and heavy rain during soybean planting and corn germination can delay sowing and damage early stands, a modest supply risk for Brazilian soy and corn. The impact on wheat harvest timing is also a minor factor for feed buyers, and prices are unlikely to move much on a single forecast.
After 1,085 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (55% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
