A winter storm is on the horizon for Montreal as a complex low-pressure system approaches Quebec on Wednesday and Thursday. This storm raises concerns due to two uncertain factors: the storm’s trajectory and the timing of temperatures dropping below freezing.
Forecast for Heavy Snow Thursday in Montreal
The expected snowfall in Montreal this Thursday may vary significantly based on the storm’s path. Weather experts are analyzing a newly forming impulse, which could bring substantial snowfall to the region. The outcome, however, remains uncertain.
Key Factors Affecting Snow Accumulation
- Storm Trajectory: The path of the storm plays a critical role in snowfall amounts. If the system moves directly through the Saint Lawrence Valley, heavy snowfall will likely be confined to the north, leaving Montreal with little accumulation. Conversely, a shift southward could lead to significant snowfalls in Montreal and Quebec City.
- Timing of Temperature Drop: The precise timing of when temperatures fall below freezing is crucial. A slight variation in temperature during Wednesday night could determine whether precipitation falls as rain or snow. A delayed drop in temperature could hinder accumulation, while an earlier transition would allow for greater snow accumulation.
Possible Snowfall Scenarios
Current forecasts indicate a wide range of possible outcomes for snow accumulation:
- Minimal accumulation if the system stays north.
- Potential for over 15 centimeters (6 inches) of snow if the storm tracks further south.
Meteorologist Bertin Osson notes the importance of these two factors. He emphasizes that even a minor change in the storm’s path could lead to different outcomes for snow amounts in Montreal and surrounding areas.
Conclusion
As winter weather approaches, residents of Montreal should prepare for varying conditions. Accurate predictions are challenged by the complexities of the developing weather system. Continuous updates will provide clarity on what to expect this Thursday.
