**Persistent high-pressure ridging over the western Mediterranean, reinforced by subtropical and African anticyclone influences, continues to advect hot, dry air northward into northern Italy, sustaining elevated temperatures across the Po Valley through the end of July.** Clear skies, light winds, and strong daytime insolation are maximizing surface heating, while Milan’s urban heat island effect adds several degrees relative to surrounding rural areas. Recent ensemble guidance from leading models (ECMWF and GFS) shows maximum temperatures clustering in the mid-to-upper 30s °C on July 31, with limited spread that keeps 36 °C and 37 °C as the two most probable outcomes and explains their near-equal market shares. Earlier 2026 European heat episodes have already produced multiple red alerts for Milan and confirmed peaks above 35 °C, providing historical context for the current setup. The market’s tight distribution around these values reflects remaining uncertainty in exact peak timing and any minor model adjustments before the official daily maximum (typically measured at Milano Linate or Malpensa stations) is recorded on July 31.
