Latest ensemble forecasts from leading models like ECMWF and GFS pinpoint Warsaw's highest temperature on March 18 at exactly 14°C, driven by a stable high-pressure ridge over Central Europe moderating mild Atlantic inflows with cloudy skies limiting solar heating. Official data from Poland's IMGW aligns, showing daytime highs stabilizing around this mark amid seasonal norms for mid-March, where averages hover near 9°C but recent mild anomalies support this outlook. Trader consensus reflects high model agreement, with minimal spread in probabilistic outputs. Realistic challenges include an unforeseen southerly wind shift or frontal boundary breakdown, potentially pushing highs to 15-16°C, though current synoptic patterns make this low-probability at under 1%.
