The top graphic is the 7 day snow cover change over the northern Hemisphere, with the bottom image depicting a graph of snow cover anomalies over the same region. It appears a recent burst of snow over Canada and Russia is contributing to this above normal marking.
I expect the Canadian snowfall to diminish over the next week or two, as a massive ridge covers most of the nation, thereby reducing chances for sustained snow cover in the region. However, the continuous building of the Siberian snowpack tells me that snow will likely return for Canada this winter, as well as much of the Eastern US.
Expect my new thoughts on this winter to come out late October-early November.
