The snow started early Saturday morning in southwestern Alberta and will intensify throughout the day.
“As this low continues to cross the Rockies, more of that Pacific moisture is starting to get drawn in,” explains Rob Davis, a meteorologist at The Weather Network.
Calgary, Medicine Hat and Lethbridge could see 10 to 15 cm of snow; that combined with sustained winds of 40 to 50 km/h means drivers could face poor visibility and treacherous conditions on the roads.
The storm begins to push into Saskatchewan later on Saturday, with the heaviest snow expected south of the Trans-Canada Highway in places like Estevan, Leader and Shaunavon, where double-digit accumulations are not out of the question, according to Davis.
Areas to the north, including Swift Current and Regina, will see lesser amounts. By Sunday, the system slides into Manitoba and northwestern Ontario, where up to 10 cm of snow is expected for some communities.
