Official forecasts from Russia's Hydrometeorological Center and supporting models indicated a daytime high of 17–19°C in Moscow on September 13, 2026, under partly cloudy skies, light westerly winds, and stable pressure around 750 mmHg. Real-time observations aligned closely with this range, peaking near 18°C by mid-afternoon before cooling into the evening, consistent with the seasonal average high of about 17°C and the absence of any anomalous warming factors. Market-implied odds reflect this tight convergence of forecast guidance and early station data, leaving minimal room for deviation. A late surge above 19°C or an official reading revision below 17°C could still alter resolution, though both appear improbable given the model consensus and current conditions.
