On the right is current snow cover in blue, superimposed with typical snow cover for this time of year, outlined in green. Right now, much of Siberia is supposed to be under snow cover. And, as you can see, blue colors exceed the climatology lines, indicating an abundance of snow cover in Siberia.
Siberian snow cover is known to be a help in predicting this winter. Multiple studies (source 1) have shown that Siberian snow cover can predict North America's winter in advance. It has been found that a lack of Siberian snow has led to below normal snowfall in the following North American winter, and this correlation is the same with above normal snowfall in Siberia.
Considering we appear to be off to the races a little bit more than normal, this bodes well with both my forecast and the hopes of many snow lovers this winter. I will be tracking Siberia through October to help me forecast the rest of winter.
