A significant weather system, characterized as a robust clipper, is forecasted to impact Quebec starting Friday evening. This phenomenon is notable for its dramatic temperature contrasts, which will result in a mix of rain and snow across various regions.
Weather Impact Overview
- Arrival: The weather system is anticipated to arrive late Friday night.
- Precipitation: Expect snow and rain across different areas on Saturday.
- Wind Speeds: Wind gusts could exceed 90 km/h in some eastern regions.
- Temperature Drops: A steep decline in temperatures is expected from Saturday to Sunday.
Little Humidity but High Activity
This system, while containing low humidity, is projected to be very active due to substantial temperature contrasts. As a result, Quebec can expect moderate yet sustained precipitation along with powerful wind gusts. A notable drop in temperatures will follow this weather system’s passage.
Snow Accumulation and Road Conditions
The clipper will likely bring significant snowfall, particularly in Northeastern Ontario, causing potential issues in regions like Abitibi and Jamésie. Specific roads to monitor include:
- Route 117: Expect partial snow coverage.
- Routes 109 and 113: Anticipate snowfall up to 10 cm.
Precipitation Trends Across Quebec
As the system moves south and east on Saturday, temperatures will rise, leading to rain in southern Quebec and snow further north. Precipitation types may vary based on real-time temperature changes. Notably:
- Route 175: May become snow-covered, impacting drivers in the Laurentian Wildlife Reserve.
- Côte-Nord: Forecasts suggest sustained snow, potentially accumulating up to 10 cm.
Wind Gust Information
The system also brings a secondary concern: strong winds. Gusts in Abitibi-Témiscamingue, the Laurentians, Outaouais, and Montreal will range from 50 to 60 km/h, while areas from Quebec to Gaspésie could see gusts hitting 70 to 90 km/h. These winds might lead to blowing snow conditions and could also damage trees, potentially causing power outages.
Expected Temperature Changes
As the front of cold air approaches, temperatures are expected to drop sharply. In the Abitibi-Témiscamingue region, a decrease of approximately 10°C could occur within three hours. In Montreal, Saturday’s afternoon high is forecasted to reach 7°C, before plummeting to -12°C by Sunday morning.
Residents are advised to take advantage of Saturday’s mild weather to clear any snow and ice from walkways to prevent hazardous conditions later. The abrupt change in temperatures could result in a layer of ice forming.
Stay tuned for updates and prepare accordingly for this robust system as it approaches Quebec.
