Snow began falling overnight in Saskatchewan, meaning people in the southern part of the province woke up to a wintery scene.
Six centimetres had accumulated in Regina by Sunday afternoon; The Pas had five centimetres and Saskatoon had three centimeters.
In addition to the snow, winds of 30 to 40 km/h caused some problems on the roads; Saskatchewan's Ministry of Transportation warned of poor visibility and slippery patches on the Trans-Canada highway from North Battleford to the Manitoba border. Officials urged drivers to avoid Highway 1 through Swift Current altogether due to blowing snow.
Snow was expected to continue falling in southeastern Saskatchewan through the day Sunday. Some places could see up to 15 cm by the time the system moves out of the region.
Parts of Alberta already felt winter's bite this week. A strong upper low from Idaho moved into the province Friday, bringing several cm of snow to Calgary, Edmonton and other cities.
Though most areas saw less than 5 cm, that was enough to cause problems for drivers unused to slippery roads.
In Calgary, traffic was snarled on several different roadways as drivers navigated icy surfaces for the first time since last spring. Police had responded to more than 300 accidents -- dozens involving injuries -- by Saturday.
Temperatures will also dip in the wake of the storm -- quite the contrast from this time last year, when several Prairie communities saw temperatures near 20°C.
Motorists are urged to winterize their vehicle and be prepared for reduced visibility and blowing snow.
