Snowy, windy clipper persists on the Prairies into Monday

Heavy snow that’s swept over portions of Saskatchewan and Manitoba on Sunday will continue pushing into northwestern Ontario into the day Monday.

A patchwork of winter storm and snowfall warnings line the path of the system across the Prairies. Mixed precipitation is possible farther south toward the international border.

Beware the risk for slow travel along the Yellowhead and Trans-Canada highways, 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.

Snow continues into Monday

This system has produced a whole spectrum of precipitation––rain, snow, and freezing rain––as it moves east across the Prairies. 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.

Temperatures will also take a dive from west to east, but it won't be enough to make it a deep freeze.
