Trader consensus on Milan's highest temperature on March 22 centers around 12°C at 30% implied probability, driven by ensemble forecasts from ECMWF and GFS models projecting daytime highs in the 11-13°C range amid a transitional weather pattern over the Po Valley. Recent developments, including a weak Atlantic front introducing cooler northerly flows and partial cloud cover, have tightened odds among these outcomes, with 11°C gaining from potential morning fog suppressing early peaks and 13°C supported by brief afternoon clearing. Historical late-March averages hover near 12°C, but short-range model uncertainty—stemming from divergent predictions on boundary layer mixing and solar insolation—keeps the market closely matched, with traders eyeing hourly updates from ARPA Lombardia stations for resolution.
