Parts of southwestern and west-central Saskatchewan are bracing for an early taste of winter as a powerful storm system moves into the region on Tuesday, bringing a mix of rain, snow, and freezing rain that is expected to create hazardous travel conditions along major routes.
Environment and Climate Change Canada (ECCC) meteorologist Brian Proctor explained that the storm is part of a “vigorous frontal system” moving across the Rockies from the BC coast. “It’s a shortwave that’s tracking almost straight eastwards across the prairies, bringing a significant swath of moisture from Alberta into southwestern and west-central Saskatchewan,” he said. “Snow will likely start developing overnight and persist throughout the day Tuesday.”
Those travelling along the Trans-Canada Highway between Medicine Hat and Swift Current should prepare for particularly messy conditions. Smith warns that “10-15 cm of snow is possible along that stretch, likely turning roads slick and visibility low.” Conditions are expected to be worse near the Alberta-Saskatchewan border, where temperatures are expected to hover near 0°C, resulting in a rain-snow mix with a risk of freezing rain.
Proctor noted that snowfall will also hit parts of west-central Saskatchewan, with 5-10 cm expected by Tuesday evening. “For those in west-central Saskatchewan, the real challenges could come from gusty winds up to 60 km/h, creating blowing snow and further visibility issues,” he explained. "We could see patchy freezing rain across southern Alberta and Saskatchewan, adding to travel risks.”
The system will bring heavy snowfall and gusty winds to the Cypress Hills area, which could receive the highest snowfall amounts due to the elevated terrain. Snowfall warnings in place for those areas.
While Proctor noted that the ground’s warmth may help prevent excessive blowing snow, the mixed precipitation and wind will still create travel hazards. “Since the ground hasn’t frozen fully, snow may stick initially, but drivers should still expect reduced visibility from blowing snow,” he said. The heaviest snow and most significant impacts are anticipated during the first part of Tuesday, especially along Saskatchewan’s western boundary with Alberta.
Motorists are advised to check weather and road reports before setting out, as the system is expected to linger in the area through Tuesday night, weakening and moving southward into Montana and the Dakotas by Wednesday morning.
“None of us are fully ready for this first real shot of winter,” Proctor said. “Drivers should be prepared to adjust their habits—take extra time and be ready for the season’s first real blast.”
