Recent short-range forecasts from European and global models show high pressure building over central Europe, promoting clear or mostly clear skies and light easterly flow over Warsaw on September 27 that favors daytime warming. Ensemble guidance and official agency runs converge on a maximum near 19–21 °C, with afternoon peaks hinging on the precise timing of any residual morning cloud and the strength of the developing easterly breeze. This places the 20 °C and 21 °C outcomes in close contention, consistent with the nearly even market-implied probabilities, while lower or higher thresholds remain outliers absent a major forecast shift before resolution. Updated model runs and official briefings in the next 24–48 hours will refine the exact peak.
