Latest ECMWF and GFS ensemble forecasts pinpoint Milan's highest temperature on March 22 clustering tightly around 13-15°C, fueling the neck-and-neck trader odds for these outcomes amid mild southerly airflow from the Mediterranean. Recent model runs show a subtle warming trend since yesterday, lifting 14-15°C probabilities as low-level clouds erode faster than initially projected, potentially unlocking greater diurnal heating. Differentiating factors include urban heat island amplification in central Milan versus cooler rural surroundings, plus uncertainty in afternoon shower timing that could cap peaks at 13°C or allow 16°C+ under clearer skies. Historical March 22 averages hover near 13.5°C at Linate station, underscoring the razor-thin model spread of ±1.5°C driving trader caution.
