Latest ECMWF and GFS ensemble forecasts project Milan's Malpensa Airport high around 19-21°C on April 4 under a strengthening high-pressure ridge across the Mediterranean, fostering clear skies and light winds that enhance Po Valley solar heating beyond the early-April climatological average of 16-17°C. Trader sentiment splits evenly among 21°C (33%), 22°C (28.5%), and 23°C or higher (28.5%) due to model divergences—GFS operational runs trending slightly warmer near 22°C amid ridge amplification, while ECMWF emphasizes potential afternoon cirrus clouds capping peaks at 20-21°C—compounded by microscale factors like sea-breeze moderation or airport-specific measurements. April 2's clearing skies yielded ~18°C highs, previewing further warming; new 12Z runs tomorrow may tip the balance before Wunderground finalizes the daily maximum.
