Key message

The trough may decide Canada’s summer. The challenge is that it will be a moving target: oscillating, stretching, and occasionally anchoring in place.

A faster west-to-east flow lowers the odds of long-lasting, continent-wide extremes, but cut-off highs and lows can still detach from the main jet stream and create impactful stretches of heat.

We forecast the season and try to anticipate the broad patterns and themes, not the individual weekends and specific weather patterns ahead. We know one bad long weekend can reshape the reputation of an entire summer.
