Current ensemble forecasts from major global models indicate Moscow's May 19 high will likely peak in the upper 20s to low 30s Celsius, driven by a strong ridge of high pressure promoting southerly warm-air advection and mostly clear skies that maximize daytime solar heating. This setup contrasts with typical mid-May climatology, where average highs hover near 18–20°C, placing the projected values several degrees above seasonal norms. Minor model disagreements center on exact cloud cover and boundary-layer mixing, which could trim peak readings by 1–2°C if afternoon convection develops. With resolution hinging on the official Rosgidromet maximum observed at the central station, traders are weighting the latest 48–72 hour guidance heavily as the final model runs approach.
