Official observations from Warsaw Chopin Airport, the market's resolution station, confirm the highest temperature on May 8 reached 12°C around 5:00 p.m. local time under partly sunny conditions with persistent cloud cover that suppressed solar heating despite short-range ECMWF and UK Met Office forecasts implying 13–14°C peaks. This aligns with IMGW reports of a cool air mass over Poland, yielding market-implied odds of 100% for 12°C as traders aggregate real-time data from airport METARs and station records. Scenarios challenging this include rare data revisions from official sources like IMGW, though highly unlikely post-verification; next hourly observations and daily summaries solidify the outcome.
