Multiple snow squalls, reduced visibility and bone-chilling temperatures invade southern Ontario

Monday, January 27, 2014, 7:32 PM -

Reduced visibility and treacherous roads were reported across southern Ontario Monday evening following a weekend of wintry weather.

Snow squall and wind chill warnings are in effect across the region.

Environment Canada is warning of squalls that can produce "near zero" visibility at times and are warning drivers to exercise caution on the road.

The conditions are courtesy of a frigid air mass that's allowing for the return of snow squalls off the Huron shores, says Weather Network meteorologist Monica Vaswani.

"A Siberian Arctic airmass has settled over Ontario once again," she says.

"It is expected to bring bitter wind chills that will feel like the -30s Monday evening into Tuesday morning, and it will generally feel like -25 to -30 through the day Tuesday across southern Ontario."

Meanwhile, in northern Ontario, wind chills are expected to exceed the -40s through Monday night.

But relief is on the way.

"Temperatures should return to more seasonal levels by the end of the work week," Vaswani says.
