Latest ensemble guidance from the National Weather Service and global models shows surface high pressure building over the Northeast, promoting light southerly flow and modest boundary-layer mixing that supports a daytime maximum near 80–83 °F at Central Park on May 18. This consensus anchors the tight clustering of implied probabilities around the 80–83 °F and 84–85 °F buckets, with traders differentiating outcomes based on subtle afternoon cloud-cover variability and any late-day sea-breeze reinforcement. Historical May climatology places the long-term average high at 75 °F, so current conditions reflect a modest warm anomaly without strong warm advection or significant moisture return. The next high-resolution model runs tonight and early Wednesday will refine the exact peak, while official NHC and local METAR observations at resolution time will determine the final bucket.
