Forecast models from the National Weather Service and private providers indicate overnight lows near 64–65°F in Denver on August 23, driven by scattered monsoon thunderstorms that limit radiative cooling under partly cloudy skies. Seasonal late-August cooling and typical dew-point levels around 50°F further support mid-60s readings, aligning with the 1991–2020 normal low of 57°F but tempered by current warmth. Trader consensus clusters on 64–69°F outcomes because short-range guidance shows only modest variability from steering flow and moisture; clearer skies could push lows toward 66–67°F, while stronger storms or wind might dip toward 62–63°F. New model runs and NWS updates through the evening will refine these thresholds before overnight observations resolve the market.
