Winter will take a long break in Quebec and Canada. Forecast.
Two sequences
According to the models, the prevailing atmospheric context would be favorable for an influx of mild air over the next two weeks. Two sequences are planned, which are interrupted by a short cold air descent. Initially, the sweetness traveled from the south of the USA to Quebec. Then the month of February would begin with a mild temperature rise from the Pacific.
A ridge is built
A strong jet stream would promote a gentle flow of air from the Pacific Ocean toward the North American continent. In fact, starting in the last days of January, a mountain ridge would emerge in western North America. This air mass could therefore move towards Quebec a little later.
A taste
Apart from the short period of two or three days during which the province would suffer from the cold, this is a foretaste of the expected spring. Let's not forget that we are still in the middle of winter. This mildness predicted by the models would be relative to this period: about 5 or 6°C above normal. In southern Quebec, the seasonal average is -6°C. During this mild weather period, the mercury would be near or slightly above freezing.
