|A spring snow covers southern Quebec this morning, after 10 to 12cm overnight.|
Heavy Rain Warning
Low pressure will move from the central Great Lakes towards Lac Saint-Jean by Thursday night. A second wave of low pressure will move north towards Lake Champlain. The combination of these two systems will produce widespread heavy rain across the entire region. Expect 25-50mm (1 to 2 inches) of rain through early Friday morning. Environment Canada has issued heavy rain warnings for Montreal and a swath of southern Quebec. The rain and melting snow will cause sharp rises in some rivers and lakes, as well as produce minor street flooding. Behind the storm, colder air will move into Montreal overnight, with a low near 3C (38F). On Friday, showers mixed with snowflakes are forecast, with colder temperatures steady near 3C.
