Southeast Saskatchewan has enjoyed a relatively mild start to the winter season. Since the start of November, we have had daytime highs well above normal, and in some cases, getting into the double digits above 0°. All of that is set to change, with Environment and Climate Change Canada calling for things to get a lot cooler in the coming days, with snow in the forecast as well. 

“We do have a low-pressure system that’s developing just south of the border, so in Montana, and that low is forecast to track to the southeast,” explained Robin Dyck, a meteorologist with ECCC. The system has prompted snowfall warnings in some parts of southwest Saskatchewan, and some of that will be coming east of Assiniboia, tracking right through Weyburn and Estevan. 

“For tonight we’ve got 5-10, so it probably won’t get to that ten-centimetre mark, but somewhere in that 8ish centimetre for tonight,” Dyck added. 

Behind the low-pressure system, though, will be an Arctic ridge that will come through the province, bringing with it temperatures well below what we have been getting used to in recent weeks.  

Dyck explained the ridge will bring northwest winds, and temperatures dropping as low as -22° in the forecast, although the meteorologist stated it may even get colder than that. The winds could also blow around the freshly fallen snow, which could reduce visibility on many highways throughout the southeast, she added.

While temperatures will be plummeting well below normal for this time of year, things are expected to get back to seasonal through the next week.
