On top of that, a roller coaster of temperature changes is approaching the Montreal region.
Saturday's high is expected to hit -10 C, while Environment Canada says Sunday's high will be 10 C.
Then temperatures will likely plummet again, to a high of -11 C on Monday.
Special weather warnings are in effect for nearly half of Quebec's surface area, including:
- Eastern Townships.
- Richelieu Valley.
- Quebec City.
The weather forecast is owed to a major low pressure system emanating from the southwestern U.S.
"We're looking at snow starting in the second half of Saturday afternoon, giving anywhere from to 10 to 15 centimetres of snow, before it changes over to freezing rain in the overnight hours, before it changes again into liquid rain sometime Sunday morning," Environment Canada forecaster Denis Thibodeau said.
The combination of types of precipitation make for particularly dangerous conditions.
"Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Take extra care when walking or driving in affected areas," reads the Environment Canada weather warning.
