Some residents in northern Ontario woke up to more than 20 cm of snow on Wednesday morning.
A strong trough that moved through Marathon and Wawa developed into an intense lake effect snow band, which brought upwards of 20 cm of snow to the Kapuskasing area, says Brian Dillon, a meteorologist at The Weather Network. 23 cm fell in just three hours.
School buses in the area were cancelled giving several students their first snow day of the season.
While most of the heaviest snow is already on the ground, an additional five to ten centimetres is possible throughout the day, warns Dillon.
As a result, visibilities will be reduced at times and motorists are advised to exercise caution on the roads.
There is also a risk for snow squalls in the Sault Ste. Marie area Wednesday evening.
We'll see a cold push of Arctic air move in, which will trigger the development of snow squalls off of Lake Superior, says Dillon. The squalls will persist for a good 24 hours with up to 25 cm of snow possible in some places by the time all is said and done.
