Dangerous Tuesday travel as lingering snow squalls hang over southern Ontario

Tuesday, November 23rd 2021, 7:40 am - Persistent snow squalls threaten as much as 30 cm of snow over the hardest hit areas of southern Ontario through Tuesday.

Snow squall warnings remain in effect for parts of southern Ontario Tuesday, with up to 30 cm of snow possible in some of the hardest hit areas. Travel will also remain difficult at times, and drivers are urged to prepare for quickly changing and deteriorating conditions, especially along the shores of Lake Huron and south of Georgian Bay. The squalls will weaken to flurries as the winds weaken throughout the day, but the next round isn't far off and threatens more difficult travel by the week's end. More on what's left to come from the snow squalls into Tuesday and beyond, below.

TUESDAY: TRAVEL REMAINS TRICKY THROUGH THE FIRST HALF OF THE DAY

Snow squalls remained persistent through Monday overnight and into early Tuesday morning across southern Ontario, and while they are forecast to dissipate through the afternoon hours, some difficult travel is still expected.

Areas along the shores of Lake Huron, western sections of the Greater Toronto Area towards Kitchener, and areas south of Georgian Bay, including Collingwood towards Barrie, will be at the greatest risk for these lingering squalls throughout Tuesday.

TIMING THE SQUALLS:

Snow squall warnings remain in effect for these regions, with the threat for up to 30 cm of snow for those that experience the most persistent squalls.

"Travel will be difficult at times and motorists are advised to exercise caution," warns Environment and Climate Change Canada. "Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow."

LOOK AHEAD: TEMPERATURE RECOVERY MID-WEEK, FOLLOWED BY MORE UNSETTLED WEATHER

The chilly air mass that has spanned much of southern Ontario will not be locked in place for very long, as seasonal temperatures return to the region by Wednesday.

Friday will be blustery and colder with scattered flurries expected, as bands of lake-effect snow set up across the snowbelt regions east and southeast of Lake Huron and Georgian Bay once again. Saturday and Sunday will be partly sunny and chilly with passing flurries, with the bands of lake-effect snow continuing across the snowbelts.

Though near seasonal temperatures are expected early next week, forecasters are closely watching the potential for a few days of very mild weather for the start of December.
