Official National Weather Service observations from the Central Park ASOS station—the authoritative source for New York City temperatures—recorded a maximum of 64-65°F on April 28, driving Polymarket trader consensus to a 100% implied probability for that outcome as the market effectively resolves. This matched pre-event National Weather Service guidance and NOAA GFS/ECMWF model consensus projecting mid-60s peaks amid a high-pressure ridge promoting subsidence, sunny skies for optimal solar heating, and light winds curbing sea-breeze moderation. Starting from morning readings near 51°F after overnight lows around 46°F, conditions adhered to late-April climatology with normal highs of 61-67°F. Realistic challenges include rare NWS data revisions from equipment calibration issues or quality control audits, though such events are exceedingly uncommon post-verification. Hourly updates through the 2-5 PM EDT peak finalized the record.
