Recent National Weather Service and model guidance indicate overnight lows in New York City on September 8 will likely settle in the low-to-mid 60s under building high pressure, northwest flow, and partly cloudy skies that support moderate radiational cooling. Forecasts from multiple sources converge on a minimum near 62–65°F, consistent with the historical average low of 64°F for the date and the season’s transition away from summer humidity. The tight spread between the 64–65°F and 66–67°F bins reflects uncertainty in exact timing of the daily minimum, urban heat-island buffering at the Central Park observation site, and minor model differences in boundary-layer mixing. Clear conditions and light winds favor the lower end of that range, while any increase in cloud cover or southerly return flow could hold temperatures a degree or two higher.
