According to Environment Canada’s forecast website on Wednesday evening, snow is expected to start falling on Thursday night with periods of snow leading into Saturday morning, stopping briefly for a few hours of sunshine before a 60 per cent chance of snow flurries on Saturday night and into Sunday morning.
Gusty winds are expected along the foothills with some areas that could see up to 70 kilometres an hour wind gusts, Lowry explained.
“Cloud cover and then how much remnant cloud is behind this front will play a role in how cold the temperatures actually get. I mean, you can see the potential for, especially where fresh snow has fallen, even minus-20 C perhaps,” he said.
“We got snow in western Alberta Wednesday morning but temperatures are still fairly moderate. By comparison, this cold front is going to be a bit stronger with the thermal gradient behind it.”
AccuWeather also released its 2020 to 2021 winter forecast for Canada, predicting another season of La Niña impacts that are likely to play a “prominent role in the general weather pattern across North America this winter.”
Senior meteorologist Brett Anderson said in the release La Niña is a climate phenomenon that results in abnormally cooler sea-surface temperatures along the equatorial Pacific Ocean. He expects there to be two distinct storm tracks that will dominate Canada this winter, one in the west and another in the east.
Regions of Alberta and British Columbia are expected to receive quite a bit of snowfall and more wind than under normal conditions.
“This will deliver numerous storms into southern British Columbia this winter, which will result in copious amounts of rainfall along the coast with heavy snowfall for ski country in the Coastal Range and also throughout the Rockies of southeastern British Columbia and southwestern Alberta,” Anderson said.
“In terms of temperatures, the core of the Arctic air is expected to hang out across northern B.C. and the Yukon Territory, but there certainly can be brief spells of bitter cold through the Prairies and into eastern Canada.”
