Snow falls in Vancouver, BC, 15 January 2020 (Vancouver PD/Twitter)
Extremely cold Arctic air has enveloped Western Canada.
Temperatures have dropped into the -30s Celsius with bitter wind chills in the -40s on the Prairies and near -50 in the northern territories.
Even the normally mild Pacific coast has not escaped a so-called Arctic outflow.
About 15 to 20 cm snow fell in Vancouver and Victoria.
Schools closed, traffic was snarled and public transit buses got stuck in a region ill-equipped to handle wintry weather.

Another intense low pressure system moved through the Maritimes on the weekend bringing a new round of heavy rain and strong winds.
After a bone-chilling start, winds changed direction and a southerly flow pushed the high in Greater Moncton to 13.8°C – close to the record of 13.9°C from 2008.
Winds were strong with gusts up to 87 km/h in Southeast New Brunswick and a peak of 91 km/h reported in Bathurst.

Snowy Highway 102 in Bedford, NS (NS Highway Cameras)
A Colorado Low tracked through the Maritimes today bringing mixed precipitation and strong winds.
The system brought the first major snowfall to Nova Scotia with 23 cm at Halifax Stanfield Airport and lesser amounts in the city but it caught drivers and plow operators off guard creating gridlock.
About 10 to 20 cm of snow also fell in central and southwestern New Brunswick where some schools closed with slippery road conditions.
Greater Moncton had a rain/snow mix this morning with 2 cm before it changed to rain.
As this system moves off to Newfoundland, brisk winds behind it will produce gusts up to 90 km/h with snow squalls expected along coastal areas.

Blustery but mild weather on Halloween continued throughout the first day of November in Southeast New Brunswick.
A cold front created strong winds with a sustained high of 64 km/h and a peak gust of 94 km/h at the Greater Moncton Airport.
Many trees and branches – already weakened by Dorian earlier this fall – came down onto power lines with NB Power dealing with almost 60,000 customers without electricity by late Friday.
Environment Canada warned of gusts up to 110 km/h in the Tantramar Marsh which forced the shutdown of the Trans Canada Highway between Amherst and Sackville until winds subsided.
The daytime high on 01 November was 19.4°C which was slightly warmer than the October maximum of 19.3°C.
The same storm system also hit Quebec where more than one million customers lost power, one man was killed by a falling tree and a canopy collapsed at a service station.
Fallen leaves, Centennial Park, Moncton, 14 Oct 2019 (Dearing)
Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.
A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.
Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.
Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.
Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.
The wind may not die down until early Saturday.

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.
Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.
Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.
Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.
Forecasters are calling for more wet weather and cooler conditions by Halloween.
