Latest ECMWF and GFS ensemble forecasts point to a midday peak near 14°C as the leading outcome for Milan's highest temperature on March 21, driven by a building upper-level ridge ushering mild southerly flow after recent cooler snaps, aligning with trader consensus at 28% implied probability. Differentiating factors include variable cloud cover from an approaching front, which could cap highs at 13°C (20%) via reduced solar insolation or allow 16°C+ (24%) under clearer skies and peak warm advection; historical March averages hover 12-14°C, but model spread reflects uncertainty in boundary layer mixing. Traders eye ARPA Lombardia's noon update for resolution cues, with 15°C (20%) viable if diurnal heating maximizes.
