Recent forecasts from the National Weather Service and models place Denver’s overnight low for August 23 in the low-to-mid 60s, with most guidance clustering near 60–66°F amid partly cloudy skies, light winds, and residual moisture from afternoon thunderstorms. High elevation promotes strong radiative cooling after sunset, but variable cloud cover and any lingering humidity from daytime convection can limit how far temperatures drop. The tight spread among leading bins (64–65°F at 46% implied probability, followed closely by adjacent ranges) reflects genuine uncertainty in exact minimum readings, driven by small differences in overnight wind, dew-point recovery, and storm timing that can shift the low by a few degrees. Official observations from Denver International Airport will resolve the market once the calendar day closes.
