A series of two Pacific storms tracked across the Rocky Mountain region bringing widespread winter conditions to western Colorado. The first system dragged a cold front across the state and spread snowfall across the western Colorado mountains and valleys of northwest Colorado. The second low pressure system dropped down into the Great Basin region and formed a closed low pressure system near the four corner region. This continued mountain snowfall across the central and southern Colorado mountains, and brought significant snow to some of the southern Colorado valleys.
