Current ensemble forecasts from European and global models indicate a minimum temperature in Milan on August 31 likely between 20–23°C under clear to mostly clear skies and light variable winds, driving the tight spread in market-implied odds across the 16–23°C bins. High pressure and minimal cloud cover promote radiational cooling overnight, yet residual warmth from recent days and urban heat island effects limit further drops, while slight model disagreements on exact wind patterns and dew points create the observed clustering around 19–21°C outcomes. No major frontal systems or advection changes are expected before resolution, though updated runs from agencies like the Italian Meteorological Service could shift probabilities if guidance revises overnight lows.
