Recent National Weather Service and model guidance indicate mild overnight conditions persisting into August 19, with forecast lows centered in the low 70s due to above-average warmth, southerly flow, and limited radiational cooling under partly cloudy skies. This aligns with trader emphasis on the 72-73°F bin, as seasonal baselines show typical August minima near 67°F yet recent days have trended warmer amid a broader heat pattern. Key variables include any last-minute shifts in dew points or cloud cover that could nudge readings a degree or two lower, with updated model runs and official observations from Central Park expected to refine probabilities before midnight.
