Trader consensus on Polymarket reflects tight uncertainty in forecast models for Milan's highest temperature on April 18, with ECMWF and GFS ensembles clustering around 24-25°C under a persistent high-pressure ridge over central Europe. This setup promotes subsidence, southerly winds advecting mild Mediterranean air, and mostly sunny skies favoring solar heating to above-normal levels—well beyond April's climatological average of 17-18°C at Milano Linate or Malpensa stations. The slim edge for 25°C stems from recent runs showing stronger boundary-layer mixing and urban heat amplification in Milan, versus cooler GFS outliers with potential afternoon clouds capping peaks at 24°C. ARPA Lombardia's morning bulletin and real-time observations will refine this before afternoon maximums.
