Trader consensus on Polymarket reflects near-certainty for Milan's highest temperature reaching 26°C or higher on April 27, driven by confirmed observational data from Milano Linate Airport—Italy's official recording station—already surpassing this threshold amid persistent high-pressure ridging over the Mediterranean. This spring heat episode, fueled by a subtropical anticyclone, has delivered highs 6-8°C above the late-April climatological average of 18-20°C, with clear skies, light southerly winds, and strong solar insolation enabling peak heating by mid-afternoon. ECMWF and GFS ensemble forecasts aligned early, corroborated by ARPA Lombardia updates over the past 48 hours showing no disruptive clouds or fronts. Realistic challenges include an improbable sudden marine inflow or station microsite anomaly, but stability through evening favors resolution to 26°C+.
