Recent ECMWF and GFS ensemble forecasts from the past 24 hours drive the tight trader consensus around 22–24°C for Milan's highest temperature on April 5, with 23°C edging out at 32% implied probability amid model spread. A persistent high-pressure ridge over the Mediterranean delivers sunny skies and mild southerly flow, pushing daytime highs well above the early April climatological average of 17–18°C at Milano Linate station, where official measurements resolve the market. Differentiating factors include variability in peak solar heating timing, boundary layer mixing, and potential for thin afternoon clouds in select runs, creating genuine uncertainty between 22°C conservative estimates and warmer 23–24°C outliers. Updated model cycles expected every 12 hours could refine this before resolution.
