Snow squalls expected in southwestern Ontario

Snow squalls are expected to impact parts of southwestern Ontario this weekend, bringing significant snowfall and hazardous travel conditions.

Environment Canada said total snowfall accumulations of 20 to 40 centimetres are expected, with locally higher amounts possible in some areas.

The weather agency said lake effect snow squalls are expected to develop off Lake Huron beginning Saturday morning, producing poor visibility due to heavy snow and blowing snow.

Conditions are expected to worsen at times, with visibility potentially reduced to near zero. Roads and walkways may become difficult to navigate due to rapidly accumulating snow, the agency warned.

Snow squalls are forecast to shift south on Sunday as winds become northerly, with conditions gradually improving later in the day.
