I suspect that we will go AWOL come February 2018, as well (worsening in March -> April). The SSTs in the NATL are a bit colder close to the coast this year, and warmer from Gulf Stream on out, which IMO portends plentiful moisture for large snowfall events into meteorological summer in some spots of Quebec -- past solstice, possibly.
Of course I could be wrong. But it is interesting to note how off the scale 2018 was compared to all other years this October. That kind of deviation re: sea ice would most definitely have been a major feature and topic for discussion (and IMO it is exactly that when happening re: snowcover OR sea ice).
The question is, how quickly does this accelerate? If 2018 is a guide, the transition to "snowy" Quebec is now happening exceedingly rapidly after the snow/loss balance turned around ~2005. After about a decade of slow ramp-umps since then, this year has blown away most others.
I suspect something similar to the period of the mid-1970s is now happening, but with a 2010s background state providing much different impacts depending on region. This was the snowiest year in Greenland since 1972. The ensuing years were marked by increasingly widespread summer Canadian snowcover until 1979.
I wonder if we see something like ^ occur again, except this time the focus will be on Quebec, where snow can accumulate much deeper than the Yukon / Nunavut (where the 70s summertime anomalies were focused).
