Mercury Set to Plummet Drastically in Coming Days

The weather forecast for the coming days indicates a significant drop in temperatures across Quebec. A cold air mass is set to arrive, potentially pushing temperatures below the 10°C mark, a notable change as autumn progresses.
Upcoming Temperature Decline in Quebec
Starting from October 20 until October 26, temperatures in southern Quebec are expected to approach seasonal norms. Meteorologist Kevin Cloutier notes that the average high during this period typically ranges between 11°C and 12°C.
Cold Snap Expected
- Temperatures may fall below 10°C on Friday and Saturday.
- This temperature drop represents the first instance since May 9 when Montreal’s temperature dips below 10°C.
- Both Ottawa and Sherbrooke have already recorded temperatures below this threshold.
Historical data shows that the first temperature drop below 10°C in Montreal occurred on October 14 in 2024 and on October 22 in 2023. The upcoming chilly days are part of a normal seasonal transition.
Factors Influencing Perception of Cold
The anticipated chill may feel more intense due to various factors, including rain, cloud cover, and windy conditions. Cloutier highlights that a temperature of 15°C can feel vastly different under sunny, calm conditions compared to a gray, rainy day.
As such, residents are reminded to prepare for the shifting conditions. If you’ve not pulled out your scarf yet, it might be time to reach for it as colder weather sets in.
