Recent forecasts from multiple models indicate a shift to increasing cloud cover and scattered showers in Warsaw on August 29 as a frontal system moves in, replacing earlier high-pressure conditions and limiting solar heating. This supports market-implied odds favoring a daily maximum near 20–21°C, with precipitation and southwesterly flow suppressing temperatures below the clearer, warmer days immediately preceding and following. Model consensus shows modest uncertainty in exact timing of rain and cloud thickness, which could differentiate outcomes between 19°C and 22°C depending on how much insolation occurs before showers develop. Historical August maxima in the region average near 24°C under typical late-summer patterns, underscoring how this synoptic setup creates the observed clustering of trader probabilities around the lower end of the seasonal range. Updated model runs and official meteorological agency guidance expected within the next 24–48 hours will likely refine these thresholds.
