The image below is a higher resolution visible satellite image courtesy of NASA Earth Observatory. This image was taken on February 5th, showing the large snow field covering much of the region after the major winter storm struck much of Northeast Colorado, Southeast Wyoming, Northwest Kansas, and Nebraska February 2-4.
And here's a close-up view of Northeast Colorado. Note the lack of snow north of a Fort Collins to Greeley line. This area received much less snowfall due to downslope flow off the higher terrain along the Wyoming Border.
