Latest ensemble guidance from ECMWF, GFS, and Russia's Hydrometeorological Center points to a modest cooling trend into August 13, with Moscow's daily maximum most likely settling between 15–17°C under increasing cloud cover, light showers, and a shift to cooler northwesterly flow behind a weak frontal boundary. Model spread remains tight for this short-range horizon, with differences in cloud timing and boundary-layer mixing creating the close contest among the leading outcomes; historical August averages near 22°C underscore the atypical suppression. Official station data at resolution time will confirm the peak, and any late adjustments to insolation or precipitation intensity represent the main variables traders are weighing.
