Here is your Thursday weather brief.
Atlantic Canada
- Maritimes: Rain forced the cancellation of several firework and Canada Day celebrations Wednesday evening. There are some clouds, fog and isolated showers Thursday morning for the Maritimes.
- Newfoundland: Showers move into Newfoundland Thursday evening, as temperatures hover around the low teens.
Ontario and Quebec
- Ontario: Downpours, gusty winds and a thunderstorm risk for Thursday, as an upper level trough pushes in for northwest portions of Ontario. The thunderstorm risk pushes into north of Lake Superior for Friday. Conditions dry out in southern Ontario and high pressure dominates the weekend forecast for the area. A cold front brings showers and the risk of thunderstorms to central Ontario Saturday.
- Quebec: The heavier band of rain lifted north Wednesday evening easing showers in Montreal and Ottawa. Rainfall warnings are still in effect for central portions of the province. As the humidex level rises, there is a risk of thunderstorms into next week.
Western Canada
- Prairies: Wildfire smoke continues to blow south into the U.S. Visibility has improved marginally. A weak shortwave trough moves east into Manitoba and northwestern Ontario. There is a risk of thunderstorms, with the potential to become severe. Large hail and gusty winds are the greatest threats with this system. A strong cold front and associated low pressure system will bring a messy mix to the Prairies this weekend. A drastic temperature drop is expected for Alberta. There is the potential for severe weather in Alberta as early as Friday afternoon.
- British Columbia: The upper ridge continues to maintain its grip over most of B.C. throughout the next couple of days. An upper level trough is expected to swing onshore Thursday evening, giving strong coastal winds of up to 70 km/h which will funnel down Georgia Strait and offshore Vancouver Island. The hot spot will likely be inland on Thursday around the 35oC to 37oC mark, with a little cooling for the coast on Friday.
