Ice storm threatens to hit parts of southern Ontario this weekend

BT Toronto | posted Thursday, Apr 12th, 2018

Talk about a weather roller-coaster.

Spring weather — with pleasant temperatures of 16 C — will hit the GTA on Thursday, but that will come to an abrupt and icy halt this weekend.

A special weather statement issued by Environment Canada warns of a potential ice storm for parts of southern Ontario on Saturday and Sunday.

The agency said the wet weather may start as rain on Saturday, but an increasing northeasterly winds will draw colder air from the Arctic high pressure system to the north, resulting in a changeover to freezing rain.

CityNews meteorologist Adam Stiles says the large spring storm is going to impact travel this weekend, especially north of Toronto. Here is a timeline of the storm and the potential risks associated with it:

Friday
Leading edge of the storm system arrives bringing scattered showers for Toronto. Snow and mixing expected in northern cottage country.

Friday Night
Steady rain sets in for Toronto. Freezing rain starts in cottage country

Stiles adds that the high winds and freezing rain could also lead to potential power outages in some areas.

Due to the storm, the city of Toronto has postponed its annual spring maintenance of the Don Valley Parkway. The DVP will no longer be closed this weekend.
