Old fashioned Canadian winter

Winter in Canada. Long. Cold. Brutal. But even by Canadian standards, this winter has been especially tough. We've been spoiled by several mild and pleasant winters in the last decade, but this season feels different. For many it feels like an old fashioned Canadian winter, where winter boots are well used and long johns are necessary.

The remarkable thing is that it’s been a very active winter right across the country. Usually when one half of the country is cold or stormy, the other half is relatively mild and calm. But almost all areas of the country have been walloped this season. Here are a few noteworthy stories:

Record Snowfall in Calgary

Calgary has received a massive amount of snow so far this winter. So much so that city crews are running out of places to put it.

In a city where brown Christmases are just as common as white Christmases, many residents haven’t seen snow piled this high in a while. In fact, Calgary received a record amount of snow in the month of December – 54 cm – the highest December snowfall in 112 years, and over triple the monthly climate normal.

Winnipeg Stuck in a Deep Freeze

Winnipeg (or “Winterpeg”) is famous for its long winters and frigid temperatures, but this season has been especially tough.

A cold air mass remained locked in place over the centre of the continent in December, making it one of the coldest Decembers in Winnipeg since the 1800s. That’s significant.


RECORD COLD: The coldest temperatures recorded...EVER


The cold temperatures have lingered into January as well, reaching a bone-chilling -38.0C (-51 with the wind chill) on January 5th. Since December 1st (the beginning of meteorological winter), sixteen days have dipped below -30C. That’s a stark contrast to the (non-)winter of 2011-2012, when Winnipeg failed to reach minus 30 once.

Sub-Zero Streak and Record Snow Pack in Newfoundland

Cold and snowy conditions weren't limited to western Canada. In Newfoundland, Stephenville and Gander set a record for consecutive days below zero.

Additionally, St. John’s, Gander, Deer Lake, and Stephenville all finished the month with a record snow pack. St. John’s snow depth on Dec. 31st was 66 cm, surpassing the previous December record of 64 cm in 1955.

#IceStorm2013 and #PolarVortex

Two major weather events had southern Ontario residents talking this winter. The worst ice storm in decades across the Greater Toronto Area left thousands without power just before Christmas, and officials estimate that the storm could end up costing the City of Toronto $100 million.

Then, in early January, an extremely cold air mass descended across the US Midwest and into the Great Lakes region. This cold air mass was, in fact, a manifestation of the polar vortex – a large upper-atmospheric circulation, usually centered around the polar regions – diving southward. Even though the polar vortex is a permanent fixture in the northern hemisphere during winter, the buzz word took off on social media.

The extreme cold was accompanied by very strong winds across southwestern Ontario. This is noteworthy given that the coldest temperatures usually occur under areas of high pressure with clear skies and calm winds. As a result, London and Kitchener broke their all-time wind chill records, hitting -42 and -41 respectively on the morning of January 7th. The cold winds also brought a massive amount of lake effect snow to the snow belt regions.

Oscillating Between Dry and Wet in BC

While the rest of Canada dealt with cold and snowy conditions, much of BC had it relatively easy in December. In fact, December 2013 was one of the driest Decembers on record for the city of Vancouver, with only 70 mm of precipitation recorded at the airport. (The climate normal is around 160 mm.)

The story changed in early January, when a train of Pacific lows impacted the south coast. Vancouver received over 100 mm of rain in five days, while the mountains received significant snow.
