Official National Weather Service observations from the automated ASOS station at Central Park, New York City's official site, recorded a maximum temperature of 43°F at 3:51 PM on March 28, 2026—peaking from hourly readings of 38°F at noon to 41°F by early afternoon—driving trader consensus to a 100% implied probability for the 42-43°F outcome. This below-normal high, against a late-March climatological average near 52°F, stemmed from a cool air mass under a persistent upper-level trough and gusty winds to 28 mph amid mostly cloudy skies, capping daytime heating after early-month record warmth. Final NWS daily climate report confirmation is pending, but realistic challenges like rare sensor recalibration or quality control adjustments are unlikely given consistent hourly data.
