Recent National Weather Service guidance and ensemble model consensus point to a Tuesday high near 86°F for Denver under partly sunny skies with only a slight afternoon thunderstorm chance, supporting the market’s tight clustering around 84–87°F. This aligns closely with the 1991–2020 climatological average high of 84.3°F for September 1. Key variables still influencing the exact peak include the timing and coverage of any convection, which could briefly suppress temperatures, versus stronger insolation and downslope warming that would favor the upper end of the favored range. Updated model runs and afternoon observations over the next 48 hours will refine the maximum before resolution.
