National Weather Service observations from Central Park, New York City's official measuring station, recorded a high temperature of 79.0°F at 3:00 PM EDT on April 1, confirming the 100% market-implied probability for the 78-79°F outcome as trader consensus aligned with verified data. This marked a significant warm anomaly above the historical April 1 average of 56°F, driven by a persistent ridge of high pressure ushering in a mild southerly flow and partly sunny skies that exceeded pre-event forecasts near 76°F from NOAA models. While authoritative station measurements carry strong evidentiary weight, realistic challenges could arise from rare post-processing revisions if instrument anomalies or quality-control flags emerge in upcoming NWS summaries, though such adjustments are infrequent for settled daily highs.
