Snow Depth Duration
This application creates a table of duration of snow cover for a given day. The default example answers the question, "When there is snow on the ground for Christmas in Ames, how long does it stick around for?" The IEM's archive of COOP snow depth reports only goes back to 1991 for most stations.
