Trader consensus on Polymarket closely splits between 21°C (32.5%), 22°C (33.5%), and 23°C or higher (26.0%) for Milan's highest temperature on April 4, reflecting ensemble forecast spreads from ECMWF and GFS models averaging near 21°C amid a high-pressure ridge ushering clear skies and southerly flows after recent rainy conditions. Differentiating factors include subtle variations in afternoon cloud cover—potentially capping peaks at 21°C—or sustained subsidence and light winds allowing full insolation for 23°C, compounded by Milan's urban heat island effect at the Linate station. ARPA Lombardia guidance projects further warming with stable weather for Easter weekend; monitor today's 12Z model updates and hourly observations for late shifts in diurnal maximums.
