The low pressure system that brought snow to parts of Manitoba and Northwestern Ontario and rain to Southwestern Ontario is hitting the Ottawa - Montreal area today.
Southwestern Ontario and the GTA
As the low moves out of the area today (Boxing Day), temperatures will drop. There is the chance of trace amounts of snow with the risk of freezing rain for areas around the GTA along the 400 highway. Drivers should continue to exercise caution on the roads Saturday. For the GTA, the system will move out today leaving conditions fairly clear for the rest of the weekend. In the traditional snowbelt areas, lake effect snow will pick up late on Boxing Day behind the system. As the system moves out only trace amounts of precipitation are expected.
Ottawa / Montreal
The system will bring a rain/ snow mix during the day with the possibility of freezing rain. The system should move out by Sunday morning with temperatures dropping behind the system. The risk of a freezing rain event is significant for Boxing Day. Drivers should use caution on Saturday as roads could be icy.
As the low moves out of the area on Boxing Day, colder temperatures behind the system could bring up to 10 cm of snow for some areas. Lake effect snow will also pick up behind the system adding to the snow accumulation and reducing visibility is some areas.
Please stay tuned for updates as this event unfolds.
