Current forecast models from agencies like the European Centre for Medium-Range Weather Forecasts indicate Moscow’s August 3 maximum will most likely reach 25–27°C under typical early-August circulation patterns, with weak high pressure and moderate southwesterly flow limiting stronger warming. Ensemble spreads and subtle differences in predicted cloud cover or boundary-layer mixing explain why trader probabilities cluster tightly around these values rather than extremes, as even small variations in incoming solar radiation or local urban heat effects can shift the daily peak by 1–2°C. Historical climatology places early August averages near 23–24°C, providing a baseline against which current guidance shows modest positive anomalies without signals of a heatwave or cold advection. Updated model runs and official briefings over the next 48 hours will likely refine these odds before resolution.
