Lake effect snow squalls could dump a few dozen centimetres of snow on parts of Midwestern Ontario by the time the weekend is over.
Snow squall warnings and watches remain in effect for much of the region. What Environment Canada called a "prolonged period of significant lake effect snow squalls" began moving through the region on Saturday. Forecasters expect they will persist into Sunday evening.
The heaviest snow is expected to fall in Grey and Bruce counties. Environment Canada forecasters suggest up to 80 centimetres of snow may fall on some areas by Sunday night. The weather agency also warns that visibilities may be reduced to near zero due to heavy snowfall and local blowing snow.
"Consider postponing non-essential travel until conditions improve. Road closures are likely. If you must travel, keep others informed of your schedule and destination and carry an emergency kit and mobile phone," Environment Canada said.
As of Sunday morning, snow squall warnings are in effect for all of Grey, Bruce, Perth, and northern Wellington County, as well as parts of Huron County.
Snowy, slippery road conditions with poor visibility persist across the region.
As of 8:00pm on Sunday, all snow squall warnings were lifted across midwestern Ontario.
