A significant snowstorm is set to impact Denver commutes and bring heavy snow accumulations to the Colorado foothills on Friday, marking the end of a 39-day streak without substantial snowfall in Denver. Most of the Denver metro area is expected to receive between 1 and 3 inches of snow, while the foothill regions, including Golden, Ken Caryl, Castle Rock, and parts of Douglas County, may see accumulations ranging from 3 to 8 inches. The snow is forecast to begin late Thursday night in the mountains and foothills, with moderate to heavy snowfall anticipated throughout Friday. Winter storm warnings and advisories are currently in effect for the central and northern mountains, where some areas could receive a foot or more of snow. Travelers in these regions should prepare for hazardous conditions and potential delays.
