Recent National Weather Service model runs indicate overnight lows for New York City on July 6 clustered in the upper 60s to low 70s, with the market's tight spread across 66–71°F bins reflecting modest ensemble disagreement on cloud cover and wind. Clearer skies would enhance radiative cooling toward the 66–69°F range, while increased humidity or a marine layer from the Atlantic could limit drops near 70–71°F. Urban heat island effects in Manhattan add a few degrees of variability compared to Central Park observations, and any late-day frontal approach could shift the minimum by 2–3°F. Updated NWS guidance and evening model runs tomorrow will likely tighten the range before resolution.
