|AccuWeather radar shows the precipitation changing from rain (green) to snow (blue) across eastern Ontario and the Ottawa Valley early Sunday morning. The snow will spread into Quebec later today.|
Low pressure located over northeast Ontario will move into central Quebec today. A second area of low pressure is currently developing over southern New England and will lift into eastern Quebec. Abundant moisture, along with cold northwest winds, will produce snow over the entire region. The snow will not taper off until late Monday. The temperature will fall to -2C (29F) tonight and rise only to 0C (32F) on Monday. The Monday-morning commute will be challenging in Montreal, to say the least. Give yourself plenty of extra time.
