Current National Weather Service and ensemble forecasts indicate Denver's minimum temperature on September 26 will likely fall in the mid-50s °F under mostly clear to partly cloudy skies, light southerly winds, and dry conditions that favor radiational cooling overnight. Model consensus shows limited spread around this range, with surface high pressure and downslope flow suppressing cloud cover and moisture. The closely matched market-implied odds for extremes above 64 °F or below 45 °F reflect residual uncertainty in exact timing of any boundary-layer mixing or minor forecast adjustments before resolution, while narrower bins around 50–59 °F capture the highest-probability outcomes based on historical September climatology and current observational trends.
