Winter isn't over yet: Burst of widespread snow to impact Ontario
A persistent Alberta clipper will bring a burst of widespread snow across Ontario through Tuesday. Forecasters are also looking at the potential for a U.S. low to bring significant impacts to parts of southern Ontario and the GTA on Thursday.
After another snowy week across Ontario last week, forecasters are looking at an incoming clipper system from the Prairies that is forecast to drop widespread snow across the entire province through Tuesday.
Forecasters are also looking ahead to the later half of the week, when a developing stateside low could bring even more snowy impacts to parts of southern Ontario, including the Greater Toronto Area (GTA).

Snowy clipper moves through Ontario Tuesday
A snowy clipper making its way across the Prairies will track through northwestern Ontario Tuesday morning, bringing up to 15 cm of snowfall to Highway 17 between Kenora and Thunder Bay, as well as to Highway 11 between Fort Frances and Thunder Bay.
The system will continue to trek east over the rest of northern Ontario throughout the morning and afternoon, bringing 10-15 cm of snow along the north shore highway to Sault Ste. Marie, which has already received more than 400 cm of snowfall so far this season.
The clipper will reach southern Ontario by the late evening hours, impacting post-dinner commutes across the GTA with heavy snow and 50-60 km/h winds.
Flurries will then linger into Wednesday as the system moves into Quebec, but we could still see some lake-effect snow bring heavier totals to the snowbelts.
Overall, southern Ontario is forecast to see a widespread 5-10 cm of snow by the end of the day Wednesday.
Stateside low could be a hit or miss Thursday
Forecasters are closely watching the developing storm track of a stateside low that could bring more snowy impacts to the GTA on Thursday.

Two scenarios could play out at this time:
Hit: The storm will lift a few kilometres north, bringing heavy snow to southwestern Ontario, including the GTA.
Miss: The storm will stay stateside and bring little snow and few impacts to southern Ontario.
As we continue through the week and more data comes in, forecasters will be able to more confidently predict the storm's track and any impacts it may bring to Ontario, so keep checking back for more updates.
