Friday, July 3, 2015, 7:03 AM - Wet conditions in some parts of eastern Canada due to a low, as the threat of severe storms lingers over regions in the West. Parts of the country will play a temperature switcheroo this weekend.

Here's your Friday weather brief.

Atlantic Canada

  • Maritimes: A low pressure system tracking through Nova Scotia could move inland, bringing rain ashore Friday morning. Another low moving offshore could develop further, resulting in more shower activity on Sunday. Sunny skies, with temperatures closer to seasonal for the rest of the Maritimes.
  • Newfoundland: Rain continues Friday afternoon into the evening for the Avalon as the low will pass by the coast of Nova Scotia and bring up to an additional 20 mm of rain for cities like St. John's. A special weather statement was issued for significant rainfall in the province as this system approaches Newfoundland from the southwest. 

Ontario and Quebec

  • Ontario: Northwestern Ontario saw scattered thunderstorms Thursday evening. There is a chance the same conditions could spark up Friday morning into the early afternoon in areas around Lake Superior. Southern portions of the region will remain slightly below seasonal but sunny as high pressure dominates. Temperatures and humidity are expected to boost to seasonal and above over the next couple of days. The next round of rain for southern Ontario will arrive on Monday into Tuesday, as a cold front from another low passes through.
  • Quebec: Another dry day for southern Quebec and the Eastern Townships with mainly sunny skies amid seasonal temperatures.

Prairies: 

Air quality advisories cover nearly two thirds of the prairie provinces due to wildfire smoke. Forecasters are keeping watch on the threat of potentially severe thunderstorms popping up Friday afternoon.

  • A strengthening Alaskan low tracks into the northern Prairies Friday, bringing a risk for thunderstorms and scattered showers through central Alberta and central and northern Saskatchewan by the afternoon. Storms are capable of producing large hail, strong winds and possible rotation, with the greatest risks through Edmonton and Red Deer. Storms are most likely to initiate around 6 p.m. local time and could last until the pre-dawn.
  • Daytime heating could spark thunderstorms in Manitoba and southern Saskatchewan.
  • Friday will be the last day in a long line of hot summer temperatures, as daily high's drop back to seasonal by Saturday. Some areas could see temperatures drop by more than 10 degrees.
British Columbia: 
  • A few temperature records were broken across the province Thursday. The hot spot was in Lillooet with 39.4oC, breaking the old record of 36.8oC in 2008. Conditions to remain hot and dry as a strong ridge remains in place. 
  • The pattern change affecting most of Canada will not be felt in British Columbia.
