Official observations from Poland's Institute of Meteorology and Water Management (IMGW) confirm Warsaw's highest temperature on May 4 reached exactly 27°C at key monitoring stations, including Chopin Airport, driving trader consensus to 100% implied probability for this outcome. This aligns with the latest ECMWF and GFS model runs from May 3, which forecasted peak highs of 26–28°C under a persistent high-pressure ridge bringing warm continental air masses, consistent with early May climatological norms where daily maxima average 19°C but can spike 8°C above amid blocking patterns. Scenarios challenging this include rare post hoc data revisions from quality control—such as sensor recalibrations or overlooked remote station peaks—but IMGW preliminary bulletins rarely shift after 24 hours, with final reports due May 6.
