Pattern change on the way: A look into the weeks ahead

January 2014 has brought two very distinct and contrasting weather patterns across Canada. The month started with a week of exceptionally cold weather with numerous records broken from the Rockies to the Atlantic. Typically when eastern Canada is unusually cold, the west is mild and vice versa, but during early January, British Columbia was the only province to escape the harsh winter conditions.

The map below highlights temperature anomalies during the first week of January.

In other words, instead of showing the actual temperature, the colours highlight regions that were warmer or colder than the seasonal temperatures for each location. 

The blue, green and purple colours indicate the colder-than-seasonal temperatures from Alberta to Newfoundland with parts of Manitoba, western Ontario and Atlantic Canada 10 to 16°C below what those regions typically see during the first week of January.

The next map shows the dramatic change in the weather pattern (our January thaw or wintermission) that occurred during the second week of January.

The orange and brown colours with embedded grays and whites highlight the regions that were as much as 16°C above seasonal for a week or longer. Northern Ontario, Quebec, much of the Maritimes and parts of Alberta and Saskatchewan experienced the warmest temperatures relative to their “normal” temperatures.
