Latest ECMWF and GFS ensemble forecasts drive trader sentiment toward a mild high of 14-16°C in Warsaw on March 23, with 15°C leading at 26% implied probability amid a high-pressure ridge ushering southerly airflow and above-normal temperatures. This reflects model consensus for peak daytime heating under partly cloudy skies, where 16°C or higher (10.5%) hinges on maximal insolation and minimal cloud interference, while 12-13°C outcomes (38.5% combined) gain traction from potential afternoon cloud increases or slight frontal influences seen in some GFS members. Historical March 23 highs average 9-11°C, but recent anomalous warmth and low wind shear favor the upper cluster; watch 12Z model updates for shifts in boundary layer mixing.
