Latest National Weather Service guidance points to mostly sunny skies and a high near 76°F in New York City on May 16, supported by light west-northwest winds and dew points in the mid-50s that limit afternoon mixing. Ensemble model runs show modest spread, with some solutions allowing brief clearing and slightly warmer boundary-layer air that could nudge the peak into the upper 70s, while others keep readings capped near 75°F. These narrow differences explain why trader-implied probabilities cluster tightly between the 76-77°F and 78-79°F bins. Historical climatology for mid-May places the expected daily maximum around 72°F, so current conditions represent a modest positive anomaly driven by a transient high-pressure ridge. Final resolution hinges on the official Central Park observation at 8 p.m. local time.
