Predict the rest of the season as you will..


Um, no, Calgary has not "received just 46% of its annual average snowfall". That's nonsense.

It seems this is where you're getting your info from:
https://twitter.com/weathernetwork/s...96244344254467

And you've totally misinterpreted what they're saying. They are NOT saying "Calgary has received just 46% of its annual average snowfall", they're saying that on average Calgary is still typically anticipating 46% of its annual snowfall over the rest of the winter. Which is... a nothingburger of a statement, we all know this already; March and April are the snowiest months in Calgary. According to TWN's chart, Calgary has received 109 cm out of an annual total of 142 cm, or ~77%.

The 'normals' (from the 1981-2010 dataset) from EC are:

September = 3.9 cm
October = 10.0 cm
November = 16.6 cm
December = 15.0 cm
January = 15.3 cm
February = 14.5 cm
March = 22.7 cm
April = 18.8 cm
May = 11.9 cm
June = 0.1 cm


Environment Canada counts from the airport weather station are:

September = 0 cm
October = 13.2 cm
November = 29.4 cm
December = 26.1 cm
January = 6.4 cm
February = trace

That January number is missing data from the 27th, which according to at least one source—our very own Acey —had 33 cm at the airport.

Spoiler!


(I figured I had ~8 cm that day at my house.)

With 33 cm added to the totals above, the cumulative snowfall since October is 108.1 cm, which is pretty close to the number The Weather Network had.

The takeaway really ought to be that this winter has actually been unusually snowy, overall.
