Warm weekend ahead for Winnipeg ... but will it be a heat wave?

Summer has finally returned to parts of Canada.
While warm temperatures are in store for the city of Winnipeg, it doesn't look like temperatures will meet heat wave credentials -- at least not in the city.
Chris Scott, a meteorologist at The Weather Network, says although the term "heat wave" gets thrown around a lot during long stretches of summer heat, a true heat wave must meet certain criteria.
A heat wave is defined as three or more consecutive days with temperatures above 32°C. Quebec has a slightly lower threshold, with a heat wave defined as three or more days with temperatures over 30°C.
These parameters mean actual heat waves are fairly rare, Scott says. “Quite often, we'll get a string of hot days, but one of them has a maximum temperature just under 32°C, which negates the official heat wave,” he explains.
Still, a southerly flow is expected to bring above-seasonal temperatures to the city, and it will get warmer as the weekend progresses.
"The warm weather will last through to next week," explains Gerald Cheng, a meteorologist at The Weather Network.
"While the weather is a bit above average, it's not out of the ordinary for Winnipeg to see weekends like this, especially in August."
