Winter Storm Watch for Montreal & southern Quebec
A Winter Storm Watch is now in effect for Montreal for late Sunday and Monday morning. Snow and freezing rain will develop late Sunday and last into the Monday morning commute before transitioning into rain from Montreal south and remaining as freezing rain from Montreal north and west into the Laurentians and Ottawa Valley. This is a very complex forecast with lots of change possible as the storm track becomes more clear. It will nevertheless bring a prolonged period of wintry precipitation, something we have not see yet this season. Travel Monday morning will be much slower and difficult than it has been in some time. The official watch from Environment Canada can be found HERE, and may be upgraded to a warning as needed depending on the exact track of the storm which is forecast to move very close to Montreal by Monday. I still believe Montreal will see more liquid precipitation than snow, but this is always a tricky scenario here in the St. Lawrence Valley and dependent on how fast the cold air is scoured off the valley floor.
