Multiple clipper systems take aim at Ontario and Quebec

An active storm track persists with the start of December across southern Ontario and Quebec, with a series of Alberta clippers bringing multiple shots of snow and rain right into this first weekend of the month. While these clippers will be relatively weak in nature, it will keep conditions unsettled, with more wintry weather hitting parts of the region. Daytime highs will also be flip-flopping, as milder Thursday temperatures give way to a chillier December weekend. More on the timing and impacts, below.

WEDNESDAY INTO THURSDAY: SNOW SPREADS ACROSS NORTHERN ONTARIO AND QUEBEC, TEMPERATURES CLIMB IN SOUTHERN ONTARIO

After a double shot at widespread snow across much of southern Ontario earlier this week, the region will see a brief reprieve from the wet weather on Wednesday, before wet snow or rain develops Wednesday night.

Snow will spread across northern sections of the province on Wednesday, sliding south into eastern Ontario and southern Quebec through the overnight hours. Periods of freezing drizzle also slicked up the roadways in the north early Wednesday, before the snow changes to mostly snow for the afternoon and evening.

In all, between 10-15 cm of snow is likely to fall through Thursday, with even heavier amounts expected for areas north of Quebec City.

Widespread rain showers will continue through Thursday afternoon for southern Ontario, as temperatures remain mild, with some mixing expected for the higher elevations into the early evening. Daytime highs could possibly reach the double-digits for areas in southwestern Ontario, with the mid to upper single digits for places like Ottawa and Montreal.

The snow across southern Quebec will also transition to rain through Thursday morning, as the system gradually makes its way out of both provinces by Thursday night.

FRIDAY INTO THE WEEKEND: LAKE-EFFECT SNOW SQUALLS RETURN, EYES ON A MESSY WEEKEND SYSTEM

Blustery and more seasonal conditions return for Friday, along with local lake-effect snow squalls for areas south and east of Lake Huron and Georgian Bay.

Another weaker clipper will spread some light snow across northern Ontario and then into southern Ontario early Saturday morning. Only minor accumulations are expected.

Forecasters are also watching the next messy system for Sunday, though with a wide range in computer model scenarios at this time. One shows a stronger system that tracks farther north, bringing snow first with a change to rain for more southern areas. Another scenario has a weaker system tracking south of the region, with just some light snow and minimal impacts expected.

"Regardless, this system should intensify and become a significant storm as it tracks into Atlantic Canada for early next week," says Dr. Doug Gillham, a meteorologist at The Weather Network.
