"An Arctic air mass continues to bring extremely cold temperatures to Alberta," the weather agency said on its website. "On Dec. 19, temperatures plummeted over the province, leading to many daily minimum temperature records being broken in the evening hours."
Global Edmonton meteorologist Jesse Beyer noted Tuesday that "wind chill values could drop close to -50 overnight tonight in parts of the province."
"Wind chills between -40 and -47 can lead to frostbite on exposed skin in five to 10 minutes, (while at) -48 and colder it can set in as soon as two minutes," he added.
"The cold will stick around for the entire work week, improving to the -5 to -10 range through the weekend."
Global Edmonton weather specialist Phil Darlington noted that "it is not totally out of the ordinary to see a lot of weather records broken at once."
"We have had similar cases when all of the province was under a heat warning," he said.
ECCC noted its summary of broken records should be considered "preliminary or unofficial information" until a final report is completed.

The differences between 1hpa and 10hpa demonstrate the underlying problem, normal models are not able to predict the volatility that is presently happening.
These changes migrate downwards, but there's a trend developing and this has to have a mechanism in operation that can so influence Earth's systems.
Our Sun and Earth's magnetic field movements I believe are part of that process.
