Cold week ahead for Montreal

A weak clipper system will give Montreal 5cm of snow Monday before another surge of arctic air tonight.

 Snow is falling this Monday afternoon in Montreal and across most of Eastern Quebec and Southern Ontario. We are not expecting much in the way of accumulations, perhaps 5cm (2 inches) in the city, and a little more to the south. It is mild currently with a temperature around -2C (29F) in Montreal. It won't last much longer as another arctic cold front is moving across the Ottawa Valley. Behind that front is a surge of cold air on gusty northwest winds. The temperature has dropped down to -13C (9F) in North Bay, Ontario this afternoon and that cold air is on the way. Expect a very cold night in the St. Lawrence Valley as the snow tapers off to a few flurries with lows plummeting to -22C (-8F). There may be a brief period of steady snow along the front late this afternoon, but it will be short lived. Skies will clear out tonight and remain that way for most of the week. High temperatures on Tuesday under sunny skies will only be -16C (3F). It will be very cold again Wednesday night, down to -20C (-4F) before we begin a slow warming trend into the upcoming weekend. At this time no major storms are on the horizon for southern Quebec and eastern Ontario.
