Special Weather Statement

Issued at 22:47 Saturday 20 January 2018

Freezing rain likely developing on Monday.

A Colorado low is forecast to cross the lower Great Lakes for the start of the work week. Some inconsequential drizzle may be present during the Monday morning commute. A few areas north from the Oak Ridges Moraine into the Dundalk Highlands may also have patchy freezing drizzle.

However, more significant freezing rain appears likely during the day Monday. Increasing easterly winds are expected to pump in slightly colder air, causing temperatures to dip to near or just below the zero degree mark. As a result, incoming precipitation from the low will likely fall as freezing rain, especially Monday afternoon and potentially into the evening. The areas most likely to be affected are north from the Oak Ridges Moraine into the Dundalk Highlands into Eastern Ontario. A few millimetres at most are expected. It is becoming less likely that the immediate Toronto area will see much freezing rain, except perhaps the northern suburbs. The fact that Arctic air is not in place prior to the onset of freezing rain should help diminish the impacts of slippery roads in some areas. However, the Monday evening commute may be impacted by icy roads in some areas.

Freezing rain warnings will likely be issued in some areas as the event approaches.
