**Forecast models indicate Moscow's peak temperature on June 13, 2026, will likely fall in the mid-to-upper 20s Celsius, consistent with the closely matched market probabilities favoring 26°C or 27°C.** Recent ensemble runs from global and regional numerical weather prediction systems show maximums clustered around 28–29°C under partly cloudy skies, with a chance of scattered showers or thunderstorms that could limit afternoon heating through increased cloud cover and evaporative cooling. Key differentiating factors include the strength and timing of warm-air advection, daytime boundary-layer mixing, and the extent of convective development. Higher outcomes near 29–30°C would require clearer skies and stronger insolation during peak solar heating in mid-June, while values at or below 26°C become more likely if thicker cloud decks or earlier precipitation develop. Historical June averages near 22°C provide context, but the current pattern follows late-May heat records that have since moderated. Traders are weighing these short-term uncertainties in model consensus ahead of the final 48-hour forecast updates.
