Recent National Weather Service and model guidance point to a minimum temperature near 67–69°F in New York City on July 24, driven by modest overnight radiative cooling under partly cloudy skies, light winds, and dew points in the low-to-mid 60s that limit further temperature drops. Ensemble spreads from the GFS and ECMWF create the tight clustering of market probabilities across the 64–73°F bins, as small shifts in cloud cover or boundary-layer mixing can easily move the low by 2–3°F. With July climatological normals around 70°F, current conditions favor values slightly below average but remain sensitive to any late-day convective remnants or urban heat-island effects at the official Central Park observing site. Updated model runs and the evening forecast discussion will be the next key inputs for traders.
