WEEKEND WEATHER: -29 wind chills, ‘significant’ snowstorm possible in southern Ontario

This comes after snowfall warnings on Wednesday in the province.

The snow squalls are expected to move south of the region late Friday morning, Environment Canada said.

Significantly reduced visibility is possible in heavy snow and local blowing snow, the warning said.

“Travel will be hazardous. Visibility will be suddenly reduced to near zero at times,” the warning said. “Roads and walkways will be difficult to navigate due to accumulating snow. Road closures are possible. Prepare for quickly changing and deteriorating travel conditions. Consider postponing non-essential travel and outdoor activities until conditions improve.”

The Niagara Region is under a special weather statement for an additional five centimetres of snow on Thursday.

The Greater Toronto Area does not have any warnings today, but there is a special message for the weekend.

“The coldest air of the season along with very cold wind chills is expected this weekend with the potential for significant snow on Sunday,” the weather forecaster said in the message.
