Early August will also see a decent amount of rainfall pushing into portions of British Columbia and Alberta. Some sporadic rain could even fall across parts of Saskatchewan and Manitoba where wildfires are currently contributing to poor air quality for large portions of the country.

The eastern cooldown won’t last long. We’ll see above-seasonal temperatures quickly return to Ontario, Quebec, and Atlantic Canada as we enter the second week of the month.
