Persistent, unusual heat on the Prairies will come with wind threat

Must read

Get ready for more of summer 2.0 on the Prairies as temperatures are set to climb high on the Prairies this week. But there’s a caveat for some areas.

Intense heat is relative by the end of September, of course. But the warmth will be so unusual that afternoon highs will be our overnight lows by Thursday morning across portions of the region.

DON’T MISS: Fall’s here, but September heat keeps rising in this Canadian town

Conditions really turn on their head by Wednesday as temperatures climb 10-15°C above seasonal for this point in September. In Saskatchewan, Saskatoon will try to reach 30°C in the final week of September –– for the first time since 2011.

Meanwhile, on Wednesday, strong, downsloping winds could gust to more than 100 km/h in the Alberta foothills.

Through Thursday

On Wednesday, an area of low pressure and cold front is driving across central Alberta, kicking up strong, downsloping winds that will gust to more than 100 km/h in the foothills. In Saskatchewan, Saskatoon will try to reach 30°C in the final week of September –– for the first time since 2011.

Even though daytime highs will touch 30°C across southern Alberta and Saskatchewan, the greatest anomalies will occur on Wednesday evening through the overnight hours, where temperatures barely dip below 20°C in pockets of the central Prairies

By Thursday, the warm air is lofted across Manitoba, with temperatures across Alberta and western Saskatchewan taking a significant tumble behind the cold front.

How unusual are we talking in Manitoba?

Take a look at The Pas, Man., where the average high temperature this time of year is about 16°C. Wednesday night’s low temperature in The Pas will come in around 18°C, making for a low temperature that’s two degrees warmer than the average high. The previous record-high minimum temperature in The Pas this late in the year was a balmy 13.5°C on the morning of Sept. 25, 2014, so we’ll watch this reading closely for any potential records.

The warmth spreads up even to Churchill, Man., which is in the midst of a record-breaking September.
