Looking at the latest guidance, it looks like a significant pattern change is in store in about a week across Canada. Between Aug. 21 and 25, there will be a surge of cool air coming down into the Prairies and perhaps a portion of British Columbia. At the same time, very warm and increasingly humid air will spread northward into the Midwest U.S., eastern Canada and the Northeast U.S., which is more typical of what we expect in August. Farther northeast, a persistent upper-level low will likely bring Newfoundland a stretch of cooler and showery weather during the above time period.
Going farther ahead, below is my latest interpretation of the European long-range forecast model weeklies going out through the second week of September.

Mild Pacific air will be common in the West and East during the month of October, as the core of cold air mostly hangs out across the North with some intrusions into the Prairies.
