After temperatures soared into the 80s Monday in parts of Colorado and Wyoming, warmth was quickly replaced by temperatures in the 30s and a late-season snow.
More than 6 inches of snow have piled up in Cheyenne through Wednesday morning, and now snow is falling across the city of Denver. Up to 18 inches of snow has been reported for parts of Larimer County.
Roadways will be slick Wednesday as the snow covers portions of I-25, I-70 and I-80 through many of Colorado's major cities. Enough snow could fall to cause dangerous travel along these routes, possibly shutting down portions of the roadways.
Around 3-6 inches of snow could accumulate in Denver on Wednesday with as much as a foot more possible in the mountains west of the city.
Other major cities to receive the winter weather include Casper, Wyo., and North Platte and Scottsbluff, Neb.
