January promises to be much more generous in snow than December.
After a marked snow deficit across Quebec, January could finally offer a real month of winter. Montreal, which has only accumulated 38 centimeters of snow since the start of the season, remains well below seasonal averages. In Val-d’Or, only 76 centimeters were measured, far from the usual 108 cm. In addition, a mild spell expected at the end of December could melt the remaining snow.
Return of snow at the start of the month
Snow could make a comeback in the first days of 2025. A transition to colder temperatures, combined with a favorable position of the jet stream, would allow the passage of winter storms at the beginning of the month.
Two scenarios for mid-January
From mid-January, the forecasts are more uncertain. Two main scenarios emerge, depending on the position of the jet stream:
1. Trajectory further south: In this case, winter storms could mainly affect the northeastern United States, making it difficult to cross the Quebec border. Quebec would then see less imposing systems, such as clippers from Alberta. These drier systems would still bring some accumulations.
2. Trajectory further north: This scenario could pave the way for abundant precipitation, particularly in the south of the province.
In any case, cold temperatures will favor snow over rain.
