Recent forecast guidance from European and global models points to a high-pressure ridge over northern Italy sustaining mild spring conditions in Milan, with daytime maxima expected between 20°C and 22°C on May 18. Subtle differences in predicted cloud cover and boundary-layer mixing explain the tight clustering around 20–21°C, as reduced insolation or light northeasterly flow could cap temperatures at the lower end while clearer skies would allow modest radiative warming. Climatological averages for mid-May near 22°C provide context, yet current ensemble spread remains wide enough to keep probabilities for adjacent outcomes nearly even. Updated model runs and local observations over the next 48 hours will refine these values ahead of market resolution.
