In the coming days, the Arctic is projected to be a massive blow to Canada and To the United States. It is expected that in the next 3 days in the rear of a deep cyclone (965гПа), which was formed due to large temperature contrasts, will begin the inflow of very cold air from Arctic regions.
The magnitude of the temperature collapse in Canada for 3 days at a height of 1.5 km can reach enormous values at 30-36°C (6°C to -30°C), in the middle troposphere at a height of 5.5 km the temperature drops to -42°C and at 2 m the temperature in some areas will decline from 5°C to -25°C.
In addition, the expected strong pressure drop. Behind the cyclone comes anticyclone (1045 – 1050гПа) that will provide rapid cooling of the air under a clear sky.
Arctic cold from Canada will displace the warm air from the Atlantic far to the North of Europe, which later (in mid March) will be the reason for the cooling in the Western, Central and Eastern Europe. By the way, even in these days in Spain is expected to removal of tropical air masses, which is expected to increase daytime temperatures up to 25 to 30°C.
