Latest ensemble forecasts from ECMWF and GFS models project Warsaw's highest temperature on April 4 around 16°C under mostly sunny conditions, concentrating trader consensus on 14-17°C outcomes with probabilities of 19-22%, yet the edge to 10°C or below at 26% stems from spread in 2-meter temperature predictions amid uncertain jet stream undulations and potential cool northerly advection from lingering Scandinavian lows. Historical climatological normals for early April average highs near 12°C, underscoring spring's high variability influenced by recent mild March trends (highs 13-14°C) and slow soil warming. Daily model refreshes will clarify steering patterns before resolution.
