  • B.C.: Prince George can expect up to 15 cm of snow, Fort St. John, 30+ cm, The Rockies, 40+ cm
  • Alberta: Edmonton is expecting up to 20 cm, which Calgary will see between 5 and 10 cm of snow. Meanwhile, communities in and around Grande Prairie may see more than 30 cm of snow accumulate.
  • Saskatchewan: SaskatoonRegina will see between 5 and 10 cm of snow.
  • Manitoba: Considerable snowfall is possible — but forecasters aren’t sure how much will fall yet. “There’s some track discrepancy at the moment,” says Weather Network meteorologist Kelly Sonnenburg.


4. WIND

“Winds in Alberta will not be exceptionally strong, however due to heavy snowfall, even weak-to-moderate winds will reduce visibility,” Sonnenburg says.

“As the clipper strengthens, southern Saskatchewan and Manitoba will most likely see stronger wind gusts as the system tracks south.”

Winds are likely to create frigid temperatures well below seasonal levels.

5. TEMPERATURES

“Strong ridging through Alaska will allow a cross polar flow to set up,” Sonnenburg says.

Daytime highs are expected to be in the minus twenties across the Prairies next week.
