Current forecast models, including GFS and ECMWF runs, indicate Warsaw's minimum temperature on September 27 will likely fall between 9–12°C under clear to partly cloudy skies and light easterly winds. Radiative cooling overnight from high pressure will drive the low, tempered by a mild air mass and dew points near 9–11°C that limit further drops. This places the outcome firmly in mid-range bins, yet the near-even split between 6°C-or-below and 16°C-or-higher reflects lingering model spread on exact nocturnal cooling rates and any last-minute wind shifts. Updated guidance through September 26–27 will clarify resolution thresholds.
