Recent numerical weather prediction models, including consensus runs from the European Centre for Medium-Range Weather Forecasts, point to a peak temperature of 28–29°C in Moscow on May 18 as the most likely outcome, driven by southerly warm-air advection under mostly clear skies and light winds. Ensemble spreads remain narrow, with afternoon boundary-layer heating expected to reach these levels before any evening cooling sets in. Historical May climatology for the city shows mean daily maxima near 18–20°C, so this represents a notable positive anomaly of roughly 8–10°C. Traders appear to weigh the tight clustering between the 28°C and 29°C contracts against modest model uncertainty in exact timing of peak insolation and potential for localized cloud development. Updated high-resolution forecasts and official Hydrometcenter observations tomorrow morning will provide the final calibration before market resolution.
