Traders see the minimum temperature in New York City on July 3 clustered tightly in the mid-80s because short-range ensemble guidance shows limited overnight radiative cooling under a strong high-pressure ridge and elevated dew points. Clear to partly cloudy skies combined with light winds and the urban heat island effect are expected to keep surface temperatures from falling much below 82°F, while any increase in low-level moisture or thicker cloud cover could allow modest additional cooling into the upper 70s. Model spread remains modest this close to the event, with the primary uncertainty tied to exact timing of any nocturnal cloud development and boundary-layer mixing. Updated National Weather Service runs and higher-resolution guidance later today will likely refine these ranges ahead of market resolution.
