Recent official forecasts from Russia's Hydrometeorological Center and GFS model runs indicate a daytime high of 16–18°C in Moscow on September 27 under variable cloud cover, light southerly winds, and minimal precipitation risk. This places the market's leading 18°C outcome (44.5% implied probability) in line with consensus projections that exceed late-September climatological norms by several degrees. Model guidance shows limited day-to-day variability through the weekend, with afternoon maxima expected near 17°C as a secondary cluster. Traders appear to weigh the narrow spread between official point forecasts and ensemble ranges, with resolution depending on the precise peak reading from Moscow-area stations. Updated model runs and any last-minute steering adjustments could refine these probabilities before Sunday.
