Signs of a March Pattern Change

A number of atmospheric teleconnections and long range forecast model data are signaling a potential major pattern change across North America around the second week of March, which may finally signal that the end of this cold, winter onslaught in eastern North America is in sight.

At the same time, as the cold backs down in the east it may shift back into western Canada for a couple of weeks in March with the potential for snow in the Rockies and Prairies.

As the westerlies possibly break through in early March we should expect a wettern pattern along the west coast, especially in the U.S. and perhaps into California.

In the meantime, we still have at least another two blasts of Arctic air into the Prairies then eastern Canada and the U.S. over the next week or so with the potential for more snowstorms.

Below is my latest interpretation of the ECMWF weekly long range forecast model output......
