Latest National Weather Service and ensemble model guidance for Denver on August 24 point to an overnight minimum in the upper 50s to mid-60s, with the tight spread among leading market outcomes reflecting genuine uncertainty in how cloud cover, scattered showers, and light southwesterly winds will modulate radiational cooling. Recent high temperatures near 90–94°F have left residual warmth in the boundary layer, while 30% thunderstorm chances and variable humidity could limit clear-sky cooling that historically produces lows near the 57°F climatological average. Forecasters emphasize that small shifts in timing of any evening convection or overnight cloud breaks remain the key variables that could push the actual minimum across the clustered 55–65°F thresholds.
