Recent National Weather Service model runs and ensemble guidance point to a Denver minimum temperature on August 25 centered in the low-to-mid 60s, driven by a stable high-pressure ridge suppressing strong overnight cooling while residual moisture from earlier monsoon activity limits radiational losses. Diurnal temperature ranges typical for late August—normally 25–30°F under clear skies—are narrowed by forecast partly cloudy conditions and light winds, keeping the overnight low from dropping toward the 50s. Historical climatology shows August 25 normals near 57°F, yet current above-average soil moisture and a lack of strong cold-air advection support the market’s clustering around 60–63°F. Key uncertainties include the timing and coverage of any late-day convection, which could alter boundary-layer mixing and shift the exact minimum by 2–3°F.
