Official forecasts from Russia's Hydrometeorological Center indicate a nighttime low near 7°C for Moscow on September 25, with daytime highs of 13–15°C under partly cloudy skies, light rain, and southerly winds of 3–10 m/s. This positions 7°C and 8°C as the closest market outcomes because subtle differences in model runs—such as exact wind speed, cloud cover duration, and radiative cooling rates overnight—can shift the minimum by 1°C. Southerly flow and precipitation moderate temperatures above typical late-September norms of around 6°C, while any earlier clearing could allow slightly deeper cooling. Updated model consensus and real-time observations through the night will refine resolution criteria for this 24-hour period.
