Official observations from Poland's Institute of Meteorology and Water Management (IMGW) and Warsaw Chopin Airport (EPWA) METAR reports confirm the city's highest temperature on May 5 peaked at 28°C during midday hours, driving Polymarket's 100% implied probability for this outcome amid clear skies and a dominant high-pressure ridge suppressing cloud cover and allowing solar heating to maximize surface temperatures. Hourly data showed steady climbs from morning lows near 12°C, topping out at 28°C before diurnal cooling set in, aligning with the latest ECMWF and GFS ensemble forecasts that converged on 27-29°C highs over the past 48 hours. This exceeds Warsaw's early May climatological average of 18-20°C, reflecting mild advection from southern air masses. Realistic challenges would require anomalous late-day urban heat island effects or discrepant readings from secondary stations prompting IMGW revisions, though multi-site consensus renders this improbable; final daily validation expected by evening.
