Current ensemble forecasts from major numerical weather prediction models cluster around daily maximum temperatures of 25–26 °C in Warsaw for July 13, consistent with the closely matched market-implied probabilities of 23 % and 21.5 %. At a two-day lead time, typical 1–2 °C spread arises from uncertainties in cloud cover, boundary-layer mixing, and the precise track of weak Atlantic fronts modulating shortwave radiation and warm-air advection. Historical July averages near 24–25 °C provide climatological context, while the absence of blocking highs or strong subsidence keeps extreme outcomes below 10 % probability. Updated model runs and observational data over the next 48 hours will narrow the distribution ahead of market resolution.
