An exceptional anomaly that has been plaguing Quebec since the beginning of the month will soon end. Indeed, the cold has every intention of resuming its rights everywhere in the province… Explanations.
Impressive softness
The first third of the month of January is interesting to say the least, in terms of the average temperature of all sectors of Quebec… Has January itself made a surprising resolution to start the new year? This is what one might believe by taking a look at the average temperature in the northeast of the province from January 1 to 10, in comparison with the thermometer in the west and south, for the same period. Temperatures have been 19° above normal since the start of the month, near Kuujjuaq! For its part, Fermont recorded 15° above its normal, while Sept-Îles experienced an anomaly of 13°. It’s exceptionally mild for the start of the year, for these sectors.
During this time, the west and south of Quebec were treated to a good dose of so-called normal cold, for the same period. For example, Montreal is right on its normal average temperature.
An atmospheric context that desires change
No matter, everything is getting ready to be put back in place. A fairly large cold air mass will envelop the province. Arctic air will descend southward for the middle of the week.
A more prolonged period of cold weather will begin to set in towards the end of the week, but especially for next week. All of Quebec will then find itself 2° to 6° below normal from January 17 to 23.
Back to a more typical scenario
It is therefore soon that Quebec will stop being reversed in this way. The cold air current that will sweep across the province in the next five days will bring these areas warmer until now in 2025 back to their climatic “habits”. Following a brief oscillation this week, greater Montreal will be treated to temperatures below -10° for several days and Kuujjuaq will be below -20°.
This “yes, yes, it’s really warmer in Kuujjuaq than in Montreal” anomaly lasted more than two weeks. An average temperature of -3° compared to a usual normal of -22° clearly does not go unnoticed… A bit like those who opt for a radical change of mind, we can say that it is an atmospheric context which had a great desire to change!
