Official observations from ARPA Lombardia meteorological stations, including Milano Linate Airport and city-center Brera, confirm Milan's highest temperature on April 1 reached exactly 16°C, anchoring trader consensus at a 100% implied probability for this outcome amid negligible odds for alternatives. Hourly data captured this peak under partly cloudy skies, light winds, and cool continental air mass influence, matching pre-event ECMWF and GFS ensemble forecasts projecting 15-17°C highs consistent with early April climatology (historical averages near 16°C). While validated measurements carry high certainty, a rare post-processing revision—such as sensor recalibration exceeding 0.5°C—could theoretically shift resolution, though such events are exceedingly uncommon in established networks. Traders await final ARPA daily bulletin for closure.
