Trader consensus on Polymarket tilts slightly toward a 17°C high in Warsaw on April 19 (32.5% implied probability) over 18°C (27%), reflecting the spread in latest ECMWF and GFS ensemble forecasts amid a weak high-pressure ridge ushering mild continental air into central Poland. IMGW's synoptic outlook, updated April 17, projects a 16°C peak under moderate cloudiness and an approaching cool polar maritime front from the Danish straits, with possible weak rain limiting solar heating. Differentiating factors include model disagreements on frontal timing and cloud cover—earlier clearance could yield 18°C via enhanced insolation, while persistent overcast favors 16-17°C. Typical mid-April highs average 13-14°C; upcoming 00Z/12Z runs and IMGW briefings tomorrow may refine odds before resolution at Warsaw Chopin Airport.
