Here is a learned, peer-reviewed study published in Nature in 2014

In a warming climate, precipitation is less likely to occur as snowfall. A shift from a snow- towards a rain-dominated regime is currently assumed not to influence the mean streamflow significantly. Contradicting the current paradigm, we argue that mean streamflow is likely to reduce for catchments that experience significant reductions in the fraction of precipitation falling as snow.

Here is the 2001 IPPC report:

Milder winter temperatures will decrease heavy snowstorms

Here is climate expert Robert F Kennedy Jr in 2008:

In Virginia, the weather also has changed dramatically. Recently arrived residents in the northern suburbs, accustomed to today’s anemic winters, might find it astonishing to learn that there were once ski runs on Ballantrae Hill in McLean, with a rope tow and local ski club. Snow is so scarce today that most Virginia children probably don’t own a sled. But neighbors came to our home at Hickory Hill nearly every winter weekend to ride saucers and Flexible Flyers.

In those days, I recall my uncle, President Kennedy, standing erect as he rode a toboggan in his top coat, never faltering until he slid into the boxwood at the bottom of the hill. Once, my father, Atty. Gen. Robert Kennedy, brought a delegation of visiting Eskimos home from the Justice Department for lunch at our house. They spent the afternoon building a great igloo in the deep snow in our backyard. My brothers and sisters played in the structure for several weeks before it began to melt. On weekend afternoons, we commonly joined hundreds of Georgetown residents for ice skating on Washington’s C&O Canal, which these days rarely freezes enough to safely skate.

Here – lest we forget – is the most-read online story in the history of the Independent.
