Short-term ensemble forecasts from models like GFS and ECMWF point to stable high-pressure conditions over southeastern Brazil, favoring maximum temperatures of 28–29°C in São Paulo on July 28 amid typical winter subsidence and limited moisture. The narrow spread in market-implied odds between these outcomes reflects subtle differences in boundary-layer mixing and urban heat retention on the plateau, with no significant cold front or frontal passage expected in the next 24–48 hours. Recent surface observations confirm near-normal temperatures without rapid advection shifts, underscoring forecast uncertainty around exact peak timing and microscale variations that could tip resolution between adjacent thresholds.
