The live forecast above highlights Fortaleza’s conditions; for Canada this week, a powerful Pacific frontal system brings widespread rain to British Columbia while a cold Arctic ridge keeps the Prairies below freezing, with daytime highs ranging from –8°C in Calgary to 12°C in Vancouver and a sharp warming trend expected by Friday in the East.
What drives the weather pattern across Canada this week?
A deep upper-level trough over Alaska funnels moisture into British Columbia, producing heavy rain on the coast and snow in the Interior. Meanwhile, a reinforcing Arctic high across the Prairies traps cold air, keeping the weather for this week in Calgary, Edmonton and Winnipeg well below seasonal averages until a mid-week shift allows milder air to push east. Ontario and Quebec see a mixed pattern: above-zero temperatures early in the week, then a rapid cooling as the Arctic boundary slides south.
How will temperatures trend for major cities?
This week’s temperature range is broad. Vancouver settles between 8°C and 12°C with persistent rain; Calgary sees highs of –8°C to –2°C before a weekend thaw. Toronto sits near 4°C on Monday, dropping to –2°C by Wednesday, then bouncing back to 6°C by Saturday. For those checking toronto weather hourly or weather in toronto 10 days, the mid-week cold snap is the key event. The ottawa weather 14 day trend shows a similar pattern, though Ottawa stays a couple degrees colder. The weather in toronto tomorrow will be the warmest day of the workweek at 5°C.
Will there be any weather warnings this week?
Environment Canada has posted wind warnings for southeastern Alberta and snowfall warnings for northern Ontario. Check our weather warning page for updates as systems develop mid-week.
When is the best day for travel in southern Ontario?
Thursday offers the most stable conditions with light winds and a high near 3°C in Toronto. However, the morning may bring patchy freezing rain; consult toronto weather 14 day and toronto weather 30 days for longer-range planning.
Is the Calgary area expecting snow this week?
Yes. Calgary will see light snow accumulations of 5–10 cm between Monday and Wednesday, followed by a drying trend. The calgary weather for this week includes a gradual warm-up starting Friday, reaching 2°C by Sunday.
