ECMWF and GFS ensemble forecasts have driven trader consensus toward 19–21°C for Warsaw's highest temperature on April 5, with implied probabilities tightly clustered amid a sharp warming trend from prior 8–13°C guidance. An upper-level ridge is ushering mild Atlantic air via southerly flow, peaking on Easter Sunday under a warm front, though IMGW holds cooler at 11–15°C due to expected partly cloudy skies and scattered showers. Differentiating factors include model spreads on cloud cover limiting insolation versus advection strength boosting highs; historical early-April averages hover near 12°C, amplifying volatility. New ECMWF runs and GFS updates expected April 3–4 at Warsaw Chopin Airport station will clarify resolution paths.
