Snowstorm Thursday: Two Factors Complicate Montreal’s Weather Scenario
The weather in Montreal is poised for significant changes due to an impending snowstorm. This storm is influenced by a complex depression system moving through Quebec, particularly impacting the southern regions.
Forecast for Thursday: Key Factors Affecting Snowfall
The upcoming storm will be characterized by uncertainty, primarily influenced by two critical factors: the trajectory of the system and the timing of temperature drops.
System Trajectory
The path that the storm takes is essential in determining snowfall amounts. If the storm’s center passes directly over the St. Lawrence Valley, Montreal might see minimal snowfall. Conversely, a slightly southern trajectory could allow for heavier snowfall in both Montreal and Quebec City.
- If centered in the St. Lawrence Valley: Minimal snowfall expected.
- If shifted south: Potential for over 15 cm of snow.
Timing of Temperature Changes
The temperature drop is another factor contributing to the variability in snowfall predictions. A fluctuation of just one degree can significantly impact precipitation types. If temperatures remain above freezing until Thursday morning, much of the precipitation may fall as rain rather than snow.
- Late cooling could lead to rain or minimal accumulation.
- Early cooling may result in rapid snow accumulation.
Potential Snow Accumulation
Current models indicate a wide range of possible outcomes. Some forecast little to no accumulation for Montreal, while others suggest substantial snowfall could blanket the area.
Meteorologist Bertin Ossonon emphasizes the high level of uncertainty regarding the snowstorm. He highlights that either outcome remains possible based on the aforementioned factors. As the storm approaches, continued monitoring will provide clarity on exact conditions expected in Montreal.
