Recent numerical weather prediction model runs from the European Centre for Medium-Range Weather Forecasts and GFS ensembles indicate Moscow’s July 19 daytime maximum will likely fall in the 26–28 °C range under a building surface high-pressure ridge with light southerly flow and limited cloud cover, allowing stronger solar insolation. This consensus drives the tight clustering of market-implied probabilities around 26–28 °C. A modest warm anomaly relative to the 23–25 °C July climatological mean stems from the recent relaxation of a transient upper-level trough that had produced cooler, more stable conditions earlier in mid-July. Key differentiating factors include precise timing of any weak frontal passage or increased boundary-layer moisture, which could cap temperatures near 25 °C versus clearer, drier conditions favoring 28–29 °C; updated model guidance and official Russian meteorological service observations on July 18 will further refine these short-term uncertainties.
