"Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research (AER), a unit of Verisk Climate, believes the North American snow tilts the odds towards a cold winter.

“'[Siberian] snow cover has really picked up, it has rapidly advanced over the last week,” Cohen said.  “It’s ahead of anything since at least [the year] 2000...Normally on this date there is about 1 million squared kilometers of snow cover south of 60°N across Eurasia and instead this year there is 5 million.'

"Cohen says this snow cover is a 'robust, strong signal' for a negative AO this winter. He offered a sneak preview of his winter outlook, which he issues in November."
