Southeast Saskatchewan is set to bask in another mild weekend, with temperatures above seasonal averages before a significant cool-down next week. As residents enjoy the warmth, a shift in weather patterns is on the horizon, bringing the promise of typical fall conditions.
Christy Climenhaga, a scientist with Environment and Climate Change Canada, said today’s temperature will hover around the seasonal average of about 10 degrees.
“It looks like today will be pretty pleasant, maybe 12 degrees. So, you might get a little warmer than seasonal. Then in for another very mild weekend, temperatures jumping up into the mid-teens by Saturday.” Noting that temperatures could reach as high as the low twenties.
“Very warm end of the weekend and start to next week, and then we have quite a change in our pattern, a cool push of air back into the prairies bringing more seasonal temperatures for the rest of the week and next week, and maybe a little more precipitation as well.”
“What we’re seeing as we move into Tuesday is a low-pressure system moving through the southern prairies, which will bring in some of that wet weather and also a push of cooler air into the region from the north, which is bringing that more typical fall weather that you would expect with cooler conditions.”
Climenhaga explained that this change is due to an upper ridge “Which pulls warmer than normal air into the prairies quite consistently through the fall, and you know into this week, and then a big pattern change on the way for next week into that more cooler air.”
“When you’re looking at patterns where you’re seeing those upper ridges building over a region, it really stops a lot of that precipitation from happening. Kind of the systems generally miss you, and that’s kind of what we’ve been seeing for the Estevan area.”
Heading into next week, the southeast could see some precipitation; however, it likely won’t be much.
“Looks like maybe 3 to 4 centimeters or so, with more of that precipitation happening a little further north in the province, but that’s definitely a switch from what we’ve seen with that mild, sunny weather.”
