Numerical weather prediction models, including ECMWF, GFS, and Polish IMGW guidance updated within the last 24 hours, show consensus highs of 18-22°C for Warsaw on May 7, driven by a high-pressure ridge over Central Europe advecting mild Atlantic air masses amid typical spring warming. Current upper-level charts at 500 hPa confirm stable ridging, minimizing cooling influences despite scattered thunderstorms and 50% precipitation odds that may limit peaks slightly but not below 18°C. This aligns with Warsaw's climatological May average high of 19°C from historical observations. Trader consensus at 100% implied probability reflects short-range forecast accuracy exceeding 95% for daytime maxima; realistic challenges include an unforeseen cold front surge or persistent overcast skies capping solar heating, though model ensembles assign <5% odds to sub-18°C outcomes ahead of final overnight advisories.
