Trader consensus on Polymarket heavily favors Milan recording a high of 13°C (34.5%) on March 22, driven by the latest ECMWF and GFS ensemble forecasts converging on 12-14°C amid typical early spring variability in the Po Valley. These models differentiate outcomes through subtle discrepancies: ECMWF leans warmer (mean ~13.5°C) due to projected southerly airflow enhancing föhn effects, while GFS shows cooler biases (~12°C) from potential northern intrusions. Historical data from ARPA Lombardia indicates March 22 median highs of 12.5°C, with 1-2°C model spreads common 48 hours out; traders await tomorrow's high-resolution runs, as cloud cover or late cold fronts could tip the balance between these closely matched probabilities.
