Latest European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS) ensemble runs, updated in the past 24 hours, project Warsaw's highest temperature on April 12 clustering around 13–15°C under a northerly flow bringing cooler continental air masses, partial cloud cover, and light winds allowing modest diurnal heating. Poland's Institute of Meteorology and Water Management (IMGW) synoptic guidance is more conservative at 12°C maximum, citing increased cloudiness over eastern areas including Warsaw, but trader consensus—reflected in market-implied odds—with 36.5% on 14°C and 27% on 15°C or higher, favors ECMWF/GFS warmth based on recent model biases and morning soundings showing potential for afternoon sun breaks. Key differentiators include cloud evolution and exact wind shear; official highs from Warsaw Chopin Airport observations will resolve by evening, with new hourly updates expected throughout the day.
