A nation-wide pattern shift is taking place across the country, bringing the threat of lake-effect snow and flurries to southern Ontario.

"For the past 23 days, Toronto has seen above-seasonal temperatures," says Doug Gillham, a meteorologist at The Weather Network.

"But with the pattern shift, temperatures will sink slightly below seasonal in southern Ontario over the weekend."

Lake effect rain showers may pop up in southern Niagara, Kingston and Georgian Bay during this time.

By the middle of next week, an Alberta clipper will cause temperatures to sink even lower.

"That could help create lake effect snow," Gillham says. "Flurries are also possible in some places, but it's still to early to tell for sure."

Meanwhile, in the Prairies, temperatures have been chilly.

Wind gusts up to 68 km/h were recorded in Calgary on Thursday -- and in eastern portions of the region, snow showers have been spotted.

Thursday morning was a chilly one in Saskatchewan as well.

The temperature dipped to -9.5°C in Val Marie, setting a new daily record.
