Canadian city will experience 20-degree drop in temperature AND snow this week

Some Canadian communities are set for a dramatic change in weather over the next few days, according to The Weather Network.

Temperatures in the western Prairies might leave some feeling like the weather pattern has skipped fall and headed straight for winter.

While the first few days of the new season will be sunny and mild in Alberta, a sharp change is set to roll in for the second half of the week.

The forecaster predicts that temperatures in Calgary will plummet from 19 C Monday to 2 C Friday, dropping down again over the weekend with -4 C as the expected low on Sunday.

The dramatic drop in temperatures will coincide with some heavy snowfall along the Rockies. There is also a chance of snow as far east as Edmonton by the end of the weekend.

To the east of the country, summer continues to be in full flow across southern Ontario and southern Quebec.

Temperature in these regions will be in the 20s this weekend, with both Toronto and Montreal expecting to reach 24 C on Saturday.
