National Weather Service ensemble models project a daily high in the mid-70s for New York City on May 25, driven by persistent southerly warm-air advection and mostly clear skies that enhance surface heating in line with late-May climatology. This robust model consensus underpins the market-implied 100% probability for a high of 70°F or higher. Historical May averages near 74°F further align with current conditions, while minor uncertainty centers on the precise timing of any weak frontal boundary or localized marine-layer influences that could briefly limit readings. Refreshed short-range guidance will continue to refine boundary-layer details and steering flow ahead of resolution.
