Latest ECMWF and GFS ensemble forecasts indicate a consensus maximum temperature around 19-20°C for Warsaw on May 1, reflecting trader sentiment with 20°C at 44.5% and 19°C at 35.5%, amid broken clouds and light northerly winds allowing moderate solar heating above the early May historical average of 17°C. Key differentiators include subtle variations in afternoon cloud cover—thinner breaks favoring 20°C via enhanced insolation—and boundary layer stability, with urban heat at Warsaw Chopin Airport potentially tipping the balance. Model spreads capture this uncertainty, as recent 00Z runs show slight upward adjustments from cooler IMGW outlooks earlier in the week. Final IMGW hourly guidance expected later today could refine probabilities before resolution.
