Current ensemble forecasts from major models indicate a highest temperature in Warsaw on July 23 most likely between 17°C and 20°C, driving the tight clustering of market-implied odds around those outcomes. A passing Atlantic trough is expected to increase cloud cover and bring light showers or patchy rain, limiting daytime insolation and keeping maxima below seasonal July averages near 24°C. Minor differences among leading probabilities reflect subtle variations in predicted frontal timing, low-level moisture, and wind patterns across runs from agencies such as ECMWF and GFS, with updates through July 21 showing stable consensus rather than sharp shifts. Historical analogs for late-July cool outbreaks in central Poland support the current distribution, while resolution hinges on official maximum readings from Warsaw meteorological stations.
