Canada 2014-2015 Winter Forecast

This is a regional winter forecast for the nation of Canada. For more winter forecasts, please visit the 2014-2015 Winter Forecast Directory.

The Weather Centre
The winter forecast for Canada this season calls for alternating swaths of alternating temperature anomalies. In western Canada, particularly in British Columbia, slightly warmer than normal conditions are expected, as conditions warrant potentially consistent ridging along the western coast of North America. On the other side of Canada, covering the Nova Scotia, Newfoundland and Quebec areas, there is a threat of periods of very warm conditions. This stems from the increased risk of ridging over the Greenland region (known by many as a negative NAO phase), and could stick around for some time.

In the middle of Canada, right around Manitoba, Saskatchewan, Ontario and into the Nunavut regions, cooler than normal conditions are expected. This projection comes from the prediction that the two areas of ridging on either coast of North America may allow a piece of the dreaded polar vortex to be forced south into Canada, possibly towards the US, thus resulting in very cold conditions.

No precipitation anomalies are marked, as uncertainty is too high to demarcate any anomalies at this time. However, drier than normal anomalies might be seen in far southwestern Canada in due time, with slightly wetter than normal conditions in southern Ontario in the near future.

Explanations of why this forecast is as it is can be found on the Official 2014-2015 Winter Forecast post, accessible from the Winter Forecast Directory link at the top of this page.

I'm confused about areas around Maine. In your US and Northeast US forecasts you have that area very cold to frigid but in your Canadian forecast your have either normal temperatures or 'Risk for prolonged warmth' covering this same area. Could you clarify about the discrepancy here?
