Canada Weather Forecast: Ontario forecast calls for warmth and wind
Toronto is expected to reach 22 C on Wednesday, well above the normal high of 16 C for October 7.
The forecast calls for a mix of sun and cloud, a 40 per cent chance of showers and windy conditions, with the unsettled pattern continuing into Thursday and Friday.
Southwesterly winds may make the day feel more changeable, particularly for people commuting by bicycle, travelling in high-profile vehicles or spending time near exposed areas.
Ottawa is forecast to reach 18 C, with a 40 per cent chance of showers during the day and stronger southwest winds developing through the morning.
The capital region is also expected to remain unsettled through Friday, with repeated shower chances before cooler overnight temperatures arrive.
Quebec sees mild temperatures with rain chances
Montreal is expected to reach 18 C on Wednesday, with mainly cloudy skies, a 30 per cent chance of afternoon showers and south winds gusting up to 40 km/h.
Showers become more likely overnight, when the chance rises to 60 per cent, while Thursday is expected to remain mild with a high near 17 C and a 70 per cent chance of showers.
The latest Environment Canada alert page also lists severe-thunderstorm watches for multiple Quebec forecast areas, although residents should check the official alert page for their specific location because watches and warnings can change quickly.
The combination of warmth, moisture and wind means outdoor plans may need to remain flexible across southern Quebec.
Fog gives way to milder conditions in Vancouver
Metro Vancouver is beginning Wednesday under a yellow fog advisory, with visibility reported at roughly 200 metres at Vancouver International Airport early in the morning.
Environment Canada says the fog should dissipate late in the morning, with Vancouver reaching 17 C and inland areas approaching 21 C.
Drivers should slow down, use headlights and leave additional space until visibility improves.
Thursday is expected to be sunny and mild, but rain and wind are forecast to return to the region on Friday.
Prairies stay calmer before a weekend change
Calgary is forecast to reach 14 C under a mix of sun and cloud, followed by a clear night with a low near 4 C.
The city is expected to remain relatively mild through Friday before temperatures fall sharply to about 6 C on Saturday, when showers are also possible.
That pattern reflects the broader transition into autumn, when daytime temperatures can remain mild while overnight lows become noticeably colder.
What Canadians should watch next
- Fog-related visibility problems in Metro Vancouver during the early morning.
- Gusty winds and scattered showers in Ontario on Wednesday.
- Periods of rain and possible thunderstorms in parts of Quebec.
- A cooler turn in portions of the Prairies later in the week.
