Analysis: The model envisages a slightly colder winter than the average for Western Europe and the northeastern United States. A very cold anomaly is planned for Alaska and northwestern Canada, as he would softer on Russia and the southern United States.

Precipitation are weaker on Western Europe and the southern United States. They are above average in the Mediterranean basin and the northeastern United States (heavy snow).
