Recent National Weather Service guidance and ensemble model runs point to a Tuesday high near 65°F for Denver as a cold front advects cooler northeast air into the region behind Monday’s 81°F peak. Increasing cloud cover, lighter winds shifting from southwest to northeast, and a modest chance of afternoon showers are limiting surface heating and contributing to the tight clustering of market-implied probabilities around 62–67°F. Official point forecasts range from 63–66°F depending on the exact timing of cloud onset and boundary-layer mixing, while historical mid-October climatology for Denver shows a mean daily maximum near 66°F. Traders appear to be weighting the official NWS 65°F call most heavily, with dispersion reflecting uncertainty in short-range model guidance ahead of the next update cycle.
