After four days of extreme heat, the end may be in sight for the heatwave that has gripped not just Weyburn, but all of southeastern Saskatchewan.  

“We’ve had southern Saskatchewan under a ridge of high pressure, which generally means downward motion of air which clears out any clouds and causes warmer temperatures,” stated Samantha Mauti, a meteorologist with Environment and Climate Change Canada. This pressure has prompted the heat warning as daytime highs have climbed above 32°, and overnight lows have stayed above 16°. “However, to end out this week, on Friday and Saturday, we have a little bit of a system coming through bringing the temperatures down a little bit and bringing us more into a stormier pattern for Friday and Saturday.” 

That pattern for the early weekend will be rather intermittent, with no estimation of amounts being forecasted as of yet. Mauti explained this is due to the speed of the systems as they pass through.  

The unsettled weather could even continue into Sunday, with the forecast calling for periods of rain throughout the day. If the forecast holds true, it would be a rare event so far this summer – a rainy day.  

The dip in temperatures isn’t expected to last too long. Behind the unsettled weather that will bring cooler temperatures and possibly rain is another high-pressure ridge. This is expected to start to move in on Monday. 

“The possibility of some high 20s, maybe low 30s for Southern Saskatchewan for early next week, so just keep an eye on the forecast,” Mauti added.  

The heatwave, while warm, did not set any daytime high records in Weyburn, but did come close. Tuesday’s high of 34.9° was just a tenth of a degree from tying the existing record. Overnight lows, though, did see a new record set with 20.3° yesterday being the warmest overnight low recorded for July 25th.
