    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.
