Thanksgiving Snow Cover the Last Five Years
Snow cover across the Lower 48 states on Thanksgiving Day was over 20 percent in four of the past five years.

Thanksgiving 2014 had the most widespread snow coverage in the past five years at 33 percent. Boosting the snow cover that year was Winter Storm Cato, which brought widespread snowfall to the Northeast the day before Thanksgiving.
The lowest snow coverage on Thanksgiving Day in the last five years was 2012 at just 6 percent across the Lower 48. Most of the snow cover was confined to the Rocky Mountains.
Playing a role in the low amount of snow cover that year is the fact that November 2012 ranked as the eighth driest on record in continental U.S. dating to 1895.
