Forecasts for Moscow on June 15 indicate a daily maximum near 21–22°C, with market odds reflecting tight clustering around these values amid minor model spread. Key differentiators include the precise timing and coverage of afternoon showers or broken cloud, which limit surface heating, versus clearer intervals that permit stronger insolation and slightly higher peaks. Regional pressure patterns and boundary-layer moisture also influence whether convection develops early enough to suppress the high or remains delayed. Official guidance from sources like the Hydrometeorological Center of Russia and ensemble runs show limited variance in this range, consistent with typical early-summer variability where small shifts in timing alter the recorded maximum by 1–2°C. Updated model cycles and observational trends over the next 24 hours will likely refine these probabilities.
