Latest National Weather Service ensemble guidance and model runs for New York City on July 30 point to an overnight low in the mid-to-upper 60s Fahrenheit, with the tight clustering of market-implied odds around 66–71 °F reflecting modest uncertainty in cloud cover, boundary-layer mixing, and dew-point trends. Clear skies would enhance radiational cooling toward the lower end of that range, while increased moisture or light winds could limit the drop and push readings toward 70 °F. Historical July minima average near 68 °F, providing context for the current spread as forecasters await the next model cycle and any revisions to steering patterns.
