The Weather Network – Your Canada Day forecast hinges on this powerful summer trough

If you’re hoping for a sunny and warm long weekend, head all the way to the Arctic Circle, which has arguably Canada Day’s best weekend weather.

The northernmost coasts of the Northwest Territories and Yukon flirt with high 20s or low 30s as a summer ridge raises temperatures in Canada’s far north.

Western Canada will also benefit from this ridge. Occasional sunshine, with seasonal or just above temperatures are expected in BC and Alberta. However, the pleasant start to the weekend could end with isolated thunderstorms.

Frequent pop-up thunderstorms can interrupt camping, hiking or backcountry activities in mountainous areas during the second half of the weekend.

In Central Canada, Friday afternoon and evening will be one to watch for Ontario and Quebec.

While no wash-down rainfall is in sight, a classic summer forecast is expected for Toronto, Ottawa, Montreal and Atlantic Canada: hot, humid, with a chance of thunderstorms.

A subtropical air mass rising along the east coast will compete against a cold low-pressure system located in the middle of Hudson’s Bay.

The chilly May-like temperatures in central Manitoba, Ontario and Quebec, colliding with the summer heat in the south, will create an active storm barrier across the Great Lakes.

This poses the risk of isolated thunderstorms as a cold front moves through Ontario and Quebec on Canada Day, eventually reaching Atlantic Canada on Sunday.

There is uncertainty about the timing and how far south in Ontario the thunderstorm will reach, so homes in the regions mentioned should be back when more details become known.
