Market consensus has converged on a 22°C high for Moscow on August 18 because real-time surface observations and numerical weather prediction outputs from agencies including Roshydromet align on that peak value under stable high-pressure conditions and light winds. Ensemble forecasts show minimal spread around the maximum, consistent with climatological norms for mid-August when diurnal temperature ranges are modest. Official station data from Vnukovo and Domodedovo, cross-validated against satellite-derived land surface temperatures, reinforce the same threshold without exceeding it. Only a late-day model revision incorporating unforecasted cloud cover or advection from cooler air masses could shift the recorded maximum, though such adjustments remain low-probability given the current atmospheric setup. Traders view the outcome as effectively resolved given the strength of converging observational evidence.
