A low pressure system is intensifying from Colorado and moving towards Quebec. Snow is expected in southern Quebec starting Thursday evening.
Environment Canada has also issued special weather reports for several areas of the province, including the Montreal region, Quebec City, Laurentians, Llanadier and Maurice.
“These weather reports will become warnings,” said Environment Canada meteorologist Jean-Philippe Bégin, speaking of a “strong storm.”
Significant amounts of snow and blowing snow are expected through Friday. Areas in the St. Lawrence River Valley between Montreal and Quebec are expected to receive 15 to 30 centimeters of snow. Snow accumulations could reach 40 centimeters, particularly in the Bas-Saint-Laurent and Gaspésie regions.
After the snow, a transition to rain is expected with an episode of ice, according to Environment Canada.
Showers should change back to storms before gradually ending Saturday afternoon.

“We’re going to have snow in areas near the St. Lawrence River in southern Quebec with winds of 60 to 70 km/h on Friday. In areas near Quebec, we expect winds of 70 to 80 km/h.
On the temperature side, the mercury should rise as the storm hits Quebec. “It’s completely normal for temperatures to rise when you have a storm,” meteorologist Jean-Philippe Pégin added, adding that they would remain “above normal” until Sunday.
Environment Canada stresses that conditions could quickly go from “good” to “zero” Thursday and Friday, and road conditions could become hazardous due to possible ice.
