A persistent warm, humid tropical airmass across the Northeast has elevated overnight lows in New York City well above early-August climatological norms of the mid-60s, keeping the market focused on the 74–79 °F range. High dew points near 75 °F, elevated moisture, and limited clear-sky radiational cooling suppress temperature drops, while model guidance and recent observations show modest variability tied to cloud cover, scattered showers, and wind patterns that can alter the exact minimum by a degree or two. Traders price in this uncertainty because small shifts in steering flow or timing of any convective activity can differentiate between 76–77 °F and 78–79 °F outcomes; updated National Weather Service model runs and local observations tonight will provide the next key data points before resolution.
