Trader consensus on Polymarket overwhelmingly favors a highest temperature of 16°C in Milan on March 23, driven by high-resolution short-range forecasts from ECMWF and Italian ARPA Lombardia models, which converge on daytime highs of 15-17°C amid mild spring conditions with light southerly winds and partial cloud cover. Verified ensemble predictions show low spread (±1°C) typical for 24-48 hour outlooks, supported by recent soundings indicating stable boundary layer temperatures around 16°C at peak solar heating near 1400 UTC. Realistic challenges include an unexpected afternoon cold front—unlikely per current vorticity maps—or urban heat island variability at key stations like Linate Airport, potentially nudging readings to 17°C if clearer skies emerge.
