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
The leading edge of the storm system is expected to arrive bringing scattered showers for Toronto. Snow and mixing are expected in northern cottage country.

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

Saturday Morning
Rain is expected in Toronto, freezing rain & ice pellets will move into north GTA. There will be snow in cottage country.

Saturday Night
Freezing rain risk moves into Toronto (2 mm to 20 mm depending on where you are). Wind gusts pick up near 50 km/h

Sunday Morning
Freezing rain and strong winds will continue in the GTA.

Sunday Midday
Temperatures will warm back up and heavy rain moves in (20-40 mm). Wind will gust near 65-70 km/h.

Sunday night
Heavy rain will end and wet flurries will mix in. Winds will begin to taper.

Monday
There will be spotty mixed showers as the system exits the region.

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.
