A winter storm taking aim at southwestern Ontario will be “relentless.”

That’s according to Environment Canada meteorologist Gerald Cheng, who says we can expect snow to begin later this evening.

“We are expecting about 2-4 centimetres of snow. Then we’re going to get all types of precipitation. It’s going to change to ice pellets during the overnight hours. And then before the rush hour on Tuesday morning, it will be freezing rain. So when people are getting up for work, for school – that’s when the freezing rain is expected to happen,” explains Cheng.

Cheng says the temperature should rise above the freezing point after 9:00 tomorrow morning, with precipitation turning to just rain.

“The tail end of the storm may be around 9:00, that’s when the temperatures will rise above 0 and really turn everything to turn less icy,” says Cheng.
