OTTAWA, Oct 16 (Reuters) — The latest météo forecast predicts up to 20 cm of snow across Québec Saturday night, with overnight lows dropping to –5 °C. The storm follows a rapid cold snap that will push nighttime temperatures below zero across the province.

Météo Overview: Early Snowfall Forecast for Québec

Environment Canada’s national weather service upgraded the winter warning on Saturday, citing a low‑pressure system moving northeast from the Great Lakes. The ECMWF ensemble shows a 78% chance of at least 5 cm of snow in the Montreal‑Quebec corridor, with higher totals near the Laurentians. Radar loops from 12 UTC indicated a band of precipitation intensifying over the St. Lawrence River basin.

Regional Impact and Historical Comparison

The projected snowfall would make this the earliest 10‑cm event recorded in Quebec City since 1998. In 2014, a similar early‑season storm delivered 12 cm on October 28, prompting a province‑wide travel advisory. This time, the colder air mass is deeper, increasing the risk of ice formation on bridges and overpasses.

Timeline and Snow Accumulation Data

The following table summarizes the key parameters expected between 22:00 UTC Saturday and 06:00 UTC Sunday:

Parameter	Details	Recommendation
Snowfall amount	10‑20 cm (model range)	Clear driveways early
Temperature low	–3 °C to –7 °C	Dress in layers, limit travel
Wind speed	15‑25 km/h gusts	Secure loose objects
Probability of snow	78% (ECMWF)	Monitor updates

Official Statements and Future Outlook

Quebec Minister of the Environment, Isabelle Tremblay, said in a press briefing, “The current **météo** scenario warrants immediate precautionary measures. We are deploying snow‑clearing crews to priority routes and will issue travel advisories as conditions evolve.” The ministry plans to reassess the system at 03:00 UTC Sunday and may extend the winter weather warning through Monday if snowfall exceeds 15 cm.

Frequently Asked Questions

How should drivers prepare for the upcoming winter storm?

Clear all sidewalks and driveways before midnight, keep a full tank of fuel, and avoid non‑essential trips until the snow‑plow crews have passed.

Will the early snow affect power infrastructure?

Cold temperatures combined with wet snow increase the risk of line loading; utility companies have pre‑positioned crews to address potential outages.
