Recent model runs from ECMWF and other ensembles show Warsaw maximum temperatures on July 17 centered near 30–31 °C, with trader-implied odds reflecting typical 1–2 °C spread at a two-day lead time. A persistent high-pressure ridge over central Europe, combined with dry antecedent soils from the early-July heatwave and clear-sky solar heating, favors readings in this range while limiting convective cooling. Minor differences among 30 °C, 31 °C, and 32 °C brackets hinge on small variations in boundary-layer mixing, afternoon cloud timing, and exact steering of the ridge axis. Official station observations at Chopin Airport will resolve the market once the daily maximum is recorded.
