Latest ECMWF ensemble and Polish IMGW forecasts cluster Warsaw's May 15 maximum temperature around 19-20°C, fueling the razor-thin trader consensus with 32% implied probability for 19°C and 31% for 20°C, reflecting southerly airflow delivering warmer air masses after recent cold snaps featuring daytime highs of 10-14°C and overnight frost. Key differentiators include model spread on afternoon cloudiness and isolated showers—ECMWF medians favor cooler 19°C peaks under persistent overcast skies, while drier GFS runs support 20°C via enhanced boundary layer mixing and peak insolation; 21°C at 19% hinges on clearer conditions. Climatological May averages of 19°C anchor expectations, with IMGW's Chopin Airport observations resolving amid short-range uncertainty. Watch 00Z model updates overnight for shifts.
