A low-pressure system over the northeastern United States is predicted to bring snow to southern Quebec, Environment Canada said.
Environment Canada says 15 to 20 centimetres of snow will fall in the greater Montreal region late afternoon Monday and continuing into Tuesday.
Quebec could be pelted with up to 20 cm. of snow by Tuesday
The agency issued a snowfall warning Sunday, predicting 15 to 20 cm of snow in the Montreal area beginning Monday late afternoon and continuing overnight, along with some below-average temperatures throughout the week.

The snowfall is expected to get heavier into the evening. There may also be blowing snow on Tuesday morning, with wind gusts of about 50 km/h expected for the central and eastern parts of the province, including Montreal.
"We can expect the morning commute to be bad," said Antoine Petit, a meteorologist for Environment Canada.
The snow will create hazardous driving conditions because of reduced visibility, especially on Tuesday.
Petit said that the Eastern Townships and Gaspé Peninsula might see as much as 25 cm of snow Monday night.
"Behind the system is a cold air mass so we're going to be well below average for the next few days," he said.
"After that, we're barely reaching zero during the day and we could see [temperatures] as low as -10 C at night."
With the deadline to install winter tires being Dec. 1, the snowfall may be an issue for some drivers who have not yet made the switch.
Jesse Caron, an automotive expert at CAA-Quebec, said drivers who haven't changed their tires yet should avoid driving during this snowfall and should make an appointment to change them as soon as possible.
"People tend to wait to see the first snowflakes on the ground before it gives them the signal to make an appointment," Caron said.
CAA-Quebec recommends that drivers get their tires changed before Nov. 10. People who need to buy new tires should do it earlier in the season to ensure they can get the right kind for their car, Caron said.
"The more temperatures drop, the more the rubber on all-season tires will become harder, and hard rubber won't be able to have good grip and traction on a road that is already frozen," he said.
As for the low visibility, Caron recommends that drivers look where they're going and avoid focusing on obstacles. He said drivers should also make sure to keep a larger distance between themselves and the vehicle ahead of them.

MONTREAL — Notice to motorists who have not yet put their winter tires on, Quebecs first snowstorm is likely to hit at the beginning of the week.
This first dump of snow could complicate motorists return home late Monday afternoon in the greater Montreal area and intensify Tuesday.
However, this first winter storm should especially leave its mark off the Island of Montreal, explained the meteorologist Alexandre Parent of Environment and Climate Change Canada.
"Estrie, the centre of Quebec and eastern Quebec, Bas-Saint-Laurent, Gaspésie and Cote-Nord, will not escape, but the intensity remains to be seen," he said.
For the moment, Environment Canada forecasts 15 to 20 centimetres of snow in southern and central Quebec and possibly more in Estrie, Beauce and eastern Quebec. The snow will be accompanied by strong winds, particularly in central and eastern Quebec, which will make travel difficult.
"The impacts should be mainly Tuesday, with snow in the sky, strong winds and potentially blowing snow," said Parent.
"It could affect Montreal, but lets say that the more southerly regions have the highest probability of having significant amounts of snow because the depression will slide along the American east coast. As these areas are closer to the system, larger amounts of precipitation are expected.
"However, it could be just a taste of winter since Mother Nature can be tempted to play yo-yo," said the meteorologist. "After Nov. 20, the vast majority of models bring us to temperatures closer to normal and even above. So we could have a return to the fall, if I may put it that way, at the end of November, with a mercury that could return to around 7 or 8 degrees Celsius during the day."
In the meantime, Québec should experience a good cooling, with a temperature of about minus 15 degrees Celsius at night, with the wind factor.
"It will probably be until the end of November," said Parent, explaining that no clear trend stands out for the moment, except one.
"Currently, what we are watching is this warmer body of water on the northeastern Pacific, along the coast of British Columbia. Sometimes its going to influence the general circulation of the atmosphere, which could make us look a bit colder when we watch the episodes in the past."
