Canadians nationwide are bracing for the impact of an unusually potent jet stream poised to develop over the Pacific Ocean, warns the Weather Network's Forecast Centre. Stretching over 10,000 kilometres from China to British Columbia in a straight line, this formidable jet stream is anticipated to usher in distinct weather changes across the country.
Meteorologists project the West Coast and Northwest Territories to experience early effects, with atmospheric river events hitting British Columbia next week. This will result in a surge in temperatures, leading to substantial alpine rain. The Pacific air stream's northward movement will generate a warm air ridge, elevating temperatures by up to 20 degrees Celsius in certain regions, impacting nearly all the Northwest Territories and the entire Prairie provinces by the following Tuesday.
In Eastern Canada, the jet stream's positioning is set to introduce a different scenario. Colder air will be directed into the region, disrupting a recent temperature spike in Ontario and Quebec. While southern Ontario may eventually experience warmer air, southern Quebec is expected to remain below-freezing for most of the upcoming week. The prospect of lingering colder weather looms over Eastern Canada throughout February and March.
Atlantic Canada, on the other hand, anticipates an influx of arctic air early next week, resulting in colder-than-normal temperatures. However, the Weather Network assures a milder turn of events later in the week, with no storms expected in the region during this period.
In summary, Canadians are preparing for the impact of an exceptionally robust jet stream over the Pacific, ushering in various weather phenomena across the country. From atmospheric river events and heightened temperatures on the West Coast to colder air infiltrating Eastern Canada and milder conditions in Atlantic Canada, the nation is set for a diverse weather experience in the coming weeks.
