Trader consensus tilts toward a 15°C high in Warsaw on March 23 at 34% implied probability, propelled by the latest ECMWF and GFS ensemble forecasts averaging 14.5–15.5°C under a mild southerly airflow displacing colder continental air masses. This edges out 14°C (26.5%) and 13°C (16.5%), with differentiation hinging on model spread in afternoon boundary layer heating and potential mid-level cloud incursions from a Baltic low-pressure system—ECMWF leans warmer with clearer skies, while GFS variants introduce slight cooling. Historical March 23 highs average 9–11°C per Polish IMGW data, but this season's positive temperature anomalies (+2–3°C above normal) amplify upside risk; short-range uncertainty remains low ahead of final 00Z updates.
