Washington's 'normal' snowfall is about to fall further.
D.C. has a new average snowfall, and it’s the lowest it has ever been.
'Out with the old and in with the new. A fresh set of data, incorporating the latest decade of weather statistics, shows Washington’s long-term decline in snowfall continues.
Washington’s new “normal” snowfall, based on average amounts between 1991 and 2020, has dropped to 13.8 inches. During the three decades from 1981 to 2010, it was 15.4 inches. This recent decline reflects a steep downward trend that began a century ago. For comparable 30-year periods in the late 1800s and early 1900s, Washington’s average snowfall was 20 inches or more.
This most recent drop in Washington’s snowfall will become official when the National Oceanic and Atmospheric Administration releases its new 30-year “climate normals” in May, its decadal update of average weather conditions for every location in the United States.'>>>
