A snowy weekend is in store for parts of the southern and eastern Prairies as a moisture-packed clipper scoots into the region.
Forecasters expect a swath of heavy snow to fall from Saskatoon to Thunder Bay, including Dauphin and Winnipeg. Mixed precipitation is possible farther south toward the international border.
Beware the risk for slow travel along the Yellowhead and Trans-Canada Highways beginning Saturday night and lasting into Monday. Be sure to stay up to date on all of the weather warnings in your area, as well, and have a plan in place as conditions worsen.

This system will produce the whole spectrum of precipitation—rain, snow, and freezing rain—as it moves east across the Prairies through the weekend. Heavy snowfall rates will be the main threat during this event.
Strong winds of 50-70 km/h will make extensive blowing and drifting snow a serious problem for drivers throughout the region. Be sure to stay on top of road conditions before heading out this weekend.
We’ll watch a disturbance cross over the Rockies to start the weekend, seeding the development of our Alberta clipper during the day Saturday. Edmonton should generally see less than 5 cm of snow from this system as it gets going.
Snowfall rates will pick up as the clipper grows organized and picks up additional moisture, moving east into Saskatchewan and Manitoba through the overnight hours Saturday into early Sunday.

Expect snow to begin in Saskatoon on Saturday night and continue through Sunday morning before ending as the system pushes east. The snowfall will begin in Winnipeg by Sunday morning, increasing in intensity through the day before tapering off through the evening hours.
The heaviest snows are expected in northern Ontario, where snow will begin in Dryden and Thunder Bay on Sunday afternoon and continue through the first half of Monday.
We’re looking at some hefty snowfall totals by the end of the storm. A swath of 15-20 cm of accumulation is on tap from the Saskatoon area east toward Dauphin and Winnipeg. Locally heavier amounts up to 25 cm are possible around the Interlake Region.
Northwestern Ontario is on track to win the snowy jackpot with this clipper, where widespread totals of 20-40 cm are in the forecast, including Dryden and Thunder Bay.
