20 cm of snow coming to some parts of southern Ontario

Residents may have briefly savoured a hint of spring-like weather last week, but winter appears to linger a while longer with snow expected over the next few days in southern Ontario.

According to Instant Weather, as colder air returns it will usher in lake-effect snowfall, primarily affecting Lake Huron and the Georgian Bay shorelines. The most impacted regions could accumulate snow totals of up to 15 to 20 cm by the end of today (March 10).

The outer bands of a system tracking up from the northeastern United States may bring snow, especially to Ontario’s far eastern regions beyond Ottawa.  Meteorologists predict these areas could accumulate 10 to 15 cm of snow by Monday morning, potentially impacting commutes with hazardous road conditions and reduced visibility.

“Heavy lake-effect snow is forecasted for areas stretching from Goderich to southward through Grand Bend and even into London and south of Georgian Bay, encompassing the Meaford and Collingwood area,” Instant Weather noted on their website.

Depending on the intensity of the lake-effect snow, neighbouring areas like Port Elgin, Wingham, St. Thomas, Meaford and Collingwood could receive up to 10 cm of snow. Meanwhile, southwestern Ontario and the Golden Horseshoe are expected to see less than 5 cm of snow.

If you live in an area that could be impacted by snow, it might be a good idea to prepare for the weather by dressing warmly and planning for potential travel delays.
