Recent National Weather Service and model guidance indicate overnight lows near 69–71°F for New York City on August 22, reflecting a stable late-summer airmass with moderate humidity and limited nocturnal radiative cooling under partly to mostly cloudy skies. This keeps the market tightly bunched among the 66–71°F bins, as small differences in cloud cover, wind, or precipitation timing can shift the Central Park minimum by 2–3°F. Urban heat retention further buffers extremes compared with rural sites, while historical August climatology (average low ~67°F) provides context for the narrow spread. Updated model runs ahead of the overnight period remain the key near-term catalyst.
