Current ensemble forecasts from NOAA and NWS models indicate an overnight low in central NYC on July 25 in the mid-to-upper 60s°F, driven by a stable air mass with light winds and partial cloud cover that limits radiative cooling. This range aligns with the tightly clustered market-implied odds across 64–69°F outcomes, reflecting genuine uncertainty from small differences in urban heat retention, dew point trends, and exact timing of any clearing. Historical July minima average near 68°F, providing context for why traders assign minimal probability to extremes below 62°F or above 72°F. The next NWS forecast update and morning observations will likely narrow resolution criteria around the 65–68°F thresholds.
