Recent ensemble forecasts from major global models place Milan's expected maximum temperature for August 13 near 34–35 °C, reflecting the primary driver behind the closely matched leading probabilities. Persistent high pressure and warm advection associated with Italy's ongoing fourth summer heatwave support these values, consistent with observed highs exceeding 37 °C earlier in the month. Minor differences among outcomes hinge on subtle variations in boundary-layer mixing, urban heat-island effects at the reference station, and any late-day convective cloud development. With resolution based on official meteorological observations, traders are monitoring the next high-resolution model runs and any updates from Italian forecasting centers for shifts in the final peak.
