Numerical weather prediction models from the European Centre for Medium-Range Weather Forecasts and national meteorological services converge on a daytime maximum of 26°C in Warsaw on June 5 under a weak high-pressure ridge featuring moderate southerly flow and limited cloud cover. This setup supports surface heating consistent with early-June climatology, where average highs range 22–24°C, and narrow ensemble spreads underpin the near-certain market-implied probability for exactly 26°C. Minor deviations in convective timing, low-level moisture, or steering patterns could limit the peak to 25°C or allow a brief rise to 27°C, though current observational trends and model consensus indicate low likelihood of such shifts before resolution.
