Before I get to the weekly stuff, there will be a weak clipper-like storm tracking across the Prairies into tomorrow with a band of light snow. The map below shows the expected accumulations....
Here is my latest interpretation of the ECMWF long-range forecast model through early January. This product updates twice a week.
Shorter-range and long-range modeling consensus are still keeping most of the really cold air up across Alaska and western Canada through most of this winter. Looking at a number of models and upper-air data over the past few months, I continue to see very little support for sustained cold in the eastern half of North America; however, that does not mean there still cannot be some significant snowfall events, especially across the interior Northeast U.S. and throughout eastern Canada.
I will certainly keep you posted on future changes.

Widespread above-normal temperatures will likely dominate into the first half of December.
My thoughts on the snow through Tuesday in the East and West.
Other than a blast into western Canada next week, most of the Arctic air will remain north of the Arctic Circle into December with just brief intrusions while mild, Pacific air takes hold from west to east.
Still happy with my old snow map.
Accumulating snow this weekend for parts of southern, central and eastern Ontario.
Wild storm in the West through Tuesday. A little snow in the east for the weekend?
