Recent ensemble forecasts from major models place Warsaw's August 4 maximum near 33–34 °C, driving the near-equal market shares at 31.5 % and 33.5 %. Subtle differences in simulated boundary-layer mixing, afternoon cloud timing, and southerly warm-air advection explain the tight spread between these outcomes, while 35 °C retains 20.5 % support if daytime heating exceeds current consensus. Official guidance from the Polish Institute of Meteorology and Hydrology (IMGW) and updated ECMWF/GFS runs expected August 3 will refine local wind and insolation details ahead of the market close.
