Major Weather Pattern Change?

For most of December and January, the wind flow in the upper atmosphere has been from east to west west to east across North America as shown with the thin black lines on the 18,000' wind map from this morning:
The deep purple is the extraordinary cold (even for winter) in Canada.

The 10-day forecast from the European Center for Medium Range Forecast shows a major change in pattern very wet weather in the West and the potential for some of the very cold air to come south in about 14 days.

Stay tuned.

    I thought the wind generally travelled from west to east, not the other way around?
