Current atmospheric conditions over central Russia, including a stable high-pressure ridge and moderate southerly flow, support a daily maximum temperature of 20°C in Moscow on May 16 according to the latest consensus from major forecast models. Ensemble runs from the European Centre for Medium-Range Weather Forecasts and Global Forecast System align tightly on this peak, matching typical mid-May climatology where regional highs average 18–20°C. Official observations from stations such as Sheremetyevo are expected to confirm this value, with limited variability in final recorded data. A late-day shift to clearer skies or an unexpected warm-air advection could push readings slightly higher, though current guidance assigns low probability to such changes before the daily observation window closes.
