For the contiguous U.S. as a whole, the average temperatures almost 4 degrees above the 1901-2000 average - the warmest year since 2000.

The warm temperatures coupled with drier than average conditions resulted in much below average snowfall. Data from the Rutgers Global Snow Lab indicate snow cover extent was third lowest in its 46-year record.
