https://ccin.ca/ccw/snow/current as at 18 December 2018The decline in Snow Cover Extent (SCE) in North America is looking like maybe an event is unfolding.
SCE has now declined by about 1 million km2 in the last week or so to well below average as warmth headed North and East across the centre and East.
Snow looks like continuing to retreat in the centre and east of North America until the weekend until cold returns to most of the continent.
Snow Water Equivalent (SWE) also stalled on this day at close to +1 SD, and precipitation looks like being quite low over the next 5 days, and may fall as rain on the far NE seaboard.

Caveat
Looking at the 2017-18 snow season, it was
SWE that went up beyond reason
in February and March 2018 mainly due to a procession of North Easters dumping vast amounts of snow on N.E. Canada. SCE over North America in that period was above normal, but not to the same extent.
