Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and other global models converge on a Warsaw maximum of 26–27°C for August 14, 2026, under stable high pressure, scattered cloud cover, light southeasterly winds, and modest warm-air advection. These conditions limit afternoon heating while preventing significant cooling or convective development, producing the tight clustering reflected in current market-implied odds that place 26°C at 54% and 27°C at 25.5%. Subtle differences in boundary-layer mixing or insolation timing among model runs account for the modest probabilities on adjacent values, with any increase in cloudiness or wind likely trimming the peak by 1–2°C. Updated short-range guidance released in the next 12–24 hours will provide the final refinement before resolution.
