Current forecast consensus from National Weather Service and private models points to a Denver overnight low in the mid-60s on August 23, driven by partly to mostly cloudy skies, scattered thunderstorm activity, and light variable winds that limit radiational cooling. Diurnal temperature ranges remain compressed under this pattern, with afternoon highs near 90–92°F yielding morning minima several degrees above the late-August climatological normal of ~57°F. Model spreads create the tight market split between 64–65°F and 66–67°F bins, while the 27.5% on 57°F or below reflects residual uncertainty around clearer-sky scenarios or stronger downslope flow that could enhance cooling before sunrise. Updated model runs and NWS evening briefings will likely refine the exact threshold ahead of resolution.
