Recent National Weather Service and model guidance indicate Denver will experience clear skies and light southerly winds on October 17 after a midweek cold front, supporting strong daytime heating to the mid-70s while allowing substantial overnight radiative cooling under dry conditions. Forecast lows cluster in the upper 30s to low 40s, with limited model spread among GFS and ECMWF runs reflecting typical autumn variability in boundary-layer mixing and downslope warming. This positions the market near even odds between sub-32°F extremes and 50°F-plus readings, as traders weigh the potential for localized cold pockets against the broader warming trend following earlier 30s lows. Updated NWS briefings and evening model runs ahead of the date will likely refine the exact minimum.
