- How severe:
A couple of hours of freezing rain likely north of lakes Erie and Ontario this evening. Significant freezing rain over Eastern Ontario overnight. Risk of a flash freeze for rush hour Monday morning.
An intensifying storm centred over Southern Indiana is forecast to cross the Greater Toronto area overnight reaching Petawawa Monday morning. Heavier snow is beginning to develop across parts of Southern Ontario in advance of the low. It will quickly spread across many areas this evening from Southwestern Ontario and to the east of Lake Huron and Georgian Bay.
The snow is forecast to transition to freezing rain then to rain later this evening as temperatures rise above the freezing mark. One or two hours of freezing rain is likely north of Lake Erie and around the west end of Lake Ontario. More prolonged freezing rain is possible overnight in Eastern Ontario with potentially several hours worth before temperatures rise above zero very early Monday. This is not expected to be anything like the recent severe ice storm.
In the wake of the storm, bitterly cold west to northwest winds will develop on Monday. There is a risk of flash freeze conditions near the path of the low where temperatures have briefly risen above zero then fall shaprly early Monday. This may include the Greater Toronto area. These winds will produce widespread dangerous wind chills beginning Monday night as some of the coldest air in years produces record-shattering cold. Wind chill warnings will likely be issued later tonight.
Travel conditions are expected to deteriorate and become hazardous due to slippery conditions from snow and freezing rain, especially on untreated surfaces.
Environment Canada will continue to monitor this evolving situation and update warnings accordingly.
