For the first time this year, Manitoba may see temperatures above 30°C

Some parts of the province have already recorded 30°C temperatures, but that was a brief stint, while Winnipeg’s airport was 0.1°C below the mark last weekend.

Along with the promise of a warmup for Eastern Canada, Manitoba could see the country’s first heat warning this Sunday. The same ridge of high pressure that’s set to turn up the temperature for Ontario and Quebec will also continue to mingle in Manitoba into next week.

The ridge moving through the Prairies will see Sunday temperatures blast into the mid-30s, which may not fade until Thursday.

With the high amount of heat, we could see the first 35°C of the year on Sunday at the Manitoba-U.S. border, which could also be Canada’s first heat warning of the year.

Parts of Manitoba may meet the criteria for having two consecutive days of daytime temperatures reaching 32°C and nighttime temperatures above 16°C.

The length of the heat remains uncertain, as the ridge could move faster than expected, which would drop temperatures below 30°C Tuesday and Wednesday for southern Manitoba. Currently, the southeastern parts of the province are the most likely to experience three to four days of 30°C+ heat.

It’s also unlikely to beat Winnipeg’s all-time record for the hottest May temperature, which stood at 37.8°C on May 30, 1934.
