Arctic chill settles in Alberta, ushering in prolonged snowfall

Spring has taken a pause on parts of the Prairies this weekend, thanks to Pacific moisture interacting with Arctic air funneling south across the western Prairies. The result is snow, and considerable amounts, too, but the heaviest of it will be focused along the southern foothills. Parts of Saskatchewan may see a bit of snow, as well. Snowfall warnings are in place for areas along the foothills, where a swath of 10-15 cm is expected. For more on timing and snow impacts through the weekend, plus a look at when the milder weather returns, see below.

SATURDAY/SUNDAY: SIGNIFICANT SNOW IN PARTS OF ALBERTA, TEMPERATURES DIVE

A long-duration snowfall event is expected to continue Saturday along the eastern slopes of the Rockies. Snowfall won't be heavy, but the long-lasting nature of it could see totals pile up somewhat.

A weak, yet persistent upsloping flow, will help keep the snow falling through Sunday evening.

"We will see increasing accumulations on Saturday and into Sunday, as a low along a boundary draped across the Alberta and British Columbia border funnels upsloping winds into the southern foothills," explains Nadine Hinds-Powell, a meteorologist at The Weather Network.

The highest accumulations will be focused in the foothills, with the threat for 10-15 cm by the time the snow finally diminishes. Snowfall warnings are in effect.

The Calgary area, along and south of the QE2, may see 3-5 cm, enough to catch some drivers off guard and make for tricky travel at times throughout the weekend.

Sunday will see the light snow venture east of Highway 2, drifting into Saskatchewan. The snow will gradually diminish by Sunday evening.

LOOK AHEAD: CHANGEABLE TEMPERATURES, MILDER AIR SURGES IN SOUTHERN AREAS

A weak ridge will build over the northwestern U.S. to start next week, bringing a return to seasonal temps across the southern Prairies. They will be changeable across the region as Arctic air builds again across northern areas, while milder weather surges into southern areas at times.

There is the potential for significant snow near or just north of the Yellowhead in Alberta Monday night into Tuesday, along with the sharp temperature gradient. Cooler air returns mid-week, but then much warmer weather is possible for parts of Alberta by late-week.
