Trader consensus on Polymarket heavily favors a Milan high of 15°C at 28%, reflecting the latest ECMWF and GFS ensemble forecasts averaging 14-16°C for March 23, driven by a mild Atlantic ridge weakening mid-week. Differentiating factors include subtle model divergences: ECMWF hints at peaking at 16-17°C under clearer skies and southerly flow, while GFS leans cooler at 14-15°C with increased cloudiness from Po Valley fog. Historical late-March norms hover around 13-15°C, but urban heat island effects in Milan add 1-2°C. Italian MeteoAM updates tomorrow could shift odds, as low-pressure trough risks tempering warmth amid 2-3°C forecast uncertainty.
