A winter storm developing over Montana is expected to bring as much as 20cm of snow over the Prairie provinces this week.
Light snow will begin to spread across southern parts of Alberta, with some scattered flurries and cool rain showers expected across central Saskatchewan through Tuesday.
By Wednesday morning, widespread light snow, with possibly higher snowfall rates in the foothills and southern Alberta, will be falling in a widespread swath across Alberta, central Saskatchewan and into northern Manitoba as well.
The snow, coupled with gusty winds, could lead to difficult travel on major routes across southern Alberta Wednesday morning. With reduced visibility expected, it’s best to plan for a slower commute in the Calgary and surrounding areas.
The snow will begin to ease across Alberta on Thursday, though continuing for Saskatchewan and Manitoba through the afternoon hours. The system will then pull east out of the Prairies by Thursday evening.
“Between 15-30 cm of snow is not out of the question for areas along the northern track of the low pressure system,” says Kelly Sonnenburg, a meteorologist at The Weather Network. “Heavy snow is also likely along the southern foothills of Alberta and across the Rocky Mountains.”3
