(Travis Golby/CBC)After a mostly smoky and cooler-than-usual summer, Manitobans saw a brief spike in late August temperatures that lasted into Labour Day weekend as the season started to wind down. Sacha Robillard was at The Forks in Winnipeg taking advantage of the heat before it hibernates for the fall and winter. “[We’re] just enjoying the last few days of sunshine and warm weather as much as we can,” Robillard said, adding she’s “fully in denial” about summer ending. Dave Carlsen, a Winnipeg-based senior meteorologist with Environment and Climate Change Canada, said it was definitely hot across southern Manitoba over the past week, but nothing record-breaking. “The last week has been one of our hotter weeks of our entire summer, so I guess by comparison it seems like it was a really hot week,” Carlsen said.Some Manitobans were outside enjoying a short spike in temperatures over the Labour Day long weekend, as the cooler-than-usual summer came to and end. (Travis Golby/CBC)”This time of year, our records are still in the mid to upper 30s [C] in most of southern Manitoba, so we’d have to be getting 36, 37, 38 to be breaking any records. It doesn’t look like we hit any of those.”However, the northern Manitoba city of Thompson broke its heat record for this time of year on Sunday, Carlsen said. Heat warnings were in effect for northern Manitoba over the weekend, after temperatures hit a high of 29 C and a low of 16 overnight for consecutive days. According to the province, temperatures must reach a high of 32 to trigger a heat warning in southern Manitoba. “The top temperature yesterday was 32.7 in Thompson, that did actually break a record for that town for that date,” Carlsen told CBC News on Monday.Smoke choked sunlight, causing cooler temperatures over June, JulyThis summer was Winnipeg’s smokiest ever, with the city surpassing its 65-year-old smoke hour record at the start of August. Carlsen said the northwesterly winds pushed smoke across the province and into the capital throughout much of June and July. “What that smoke did, is it filtered the sunshine and made it a little less hot as well. All of that combined to make it cooler than a normal summer, at least parts of the summer, rather than having those really blazing temperatures in July like we normally have,” he said. The Labour Day weekend heat spell won’t last long, Carlsen warned, with typical autumn weather dropping temperatures to the mid to low teens. “There’s going to be a fairly strong cold front moving through this evening and there’s probably going to be some showers and thunderstorms along that cold front, as it passes through southern Manitoba,” Carlsen said Monday. “It will be quite the transition, quite the shock for everyone who’s been basking in these warm temperatures the last few days.”However, the warmer weather will resurface again next weekend, Carlsen said, with temperatures reaching the low 20s. “There’s still some good weather to come yet,” Carlsen said.
