Southern Ontario braces for biggest snowstorm in years

The Friday morning commute is looking to be an ugly one for Southern Ontario as the Alberta Clipper swinging through the area today is amplified by moisture from another storm system moving up from the United States.

“It might be the biggest storm since 2011,” said Rob Khun, a severe weather meteorologist with Environment Canada, referring to the March 2011 storm that dumped 12.5 cm of snow on the GTA.

Snow from the storm system has begun to fall in southwestern Ontario this morning as the Alberta Clipper tracks through the area, and it should arrive in the GTA by this afternoon. This will leave about 2 cm of accumulation on the ground, however the added moisture arriving from the south this evening will turn this to heavy snowfall overnight and into Friday morning.

Total accumulations for southern Ontario are expected to be between 15 and 25 cm of snow, and strong winds will add blowing snow to the mix, making for hazardous driving conditions tonight, through the Friday morning commute, and possibly into tomorrow afternoon as well.

Eastern Ontario is expected to be even harder hit, as snowfall accumulations already forecast to be up to 25 cm from the Alberta Clipper are pushed up to 35 cm or higher by the approaching storm from the south and local amplification due to winds blowing in off of Lake Ontario.
