Total snowfall the next 2 weeks from the last 12 European Ensemble model. Most of this is week 2.

Total snowfall the next 6 weeks(thru January 5, 2026). There will be swaths of snow laid down by individual storms/perturbations, instead of an increasing/decreasing snow gradient distribution pattern like this.

500 mb map from the last 12z European Ensemble model at 360 hours. December 6th. This is around 16,000 feet above the ground and a point where half the atmosphere's weight is above it and half of it is below it.

Anomalies compared to average. Positive anomalies west/negative anomalies east are a favorable couplet(teleconnection) for cold air to be transported from high latitudes to the middle latitudes with the streamlines/jet stream between them spreading Arctic air south, thru Canada into the US, especially the northern US.

We have an upper level ridge off the West Coast but especially from Alaska, almost to Siberia. An extremely deep low over the southwest part of the Hudson Bay is an unusually far south displaced Polar Vortex with some frigid temperatures associated with it.
