A major snowstorm is unfolding from the Rockies into the Plains, unloading more than a foot of snow across portions of Colorado.
On Wednesday morning, slick conditions were in place across portions of I-25, I-70 and I-80, including through many of Colorado's major cities.
The early-May snow will be historic across portions of the Midwest.
