Bitter chill incoming for the Prairies after quick weekend snow

Snow began spreading across parts of the southern Prairies on Saturday morning as a low-pressure system moved through the northern U.S. The system will provide nuisance snowfall totals, ranging up to 15 cm for some areas. A quick blanket of snow is a harbinger of colder days to come. A bitter Arctic chill descending over the Prairies will bring a sharp plunge in temperatures, sending wind chill values into the -30s in some spots. More on the weekend snow and impending Arctic blast, below.

WEEKEND: SHARP DIVIDE BETWEEN NORTH AND SOUTH AS SNOWY SYSTEM PUSHES IN

A chilly pattern settling across the Prairies this weekend will set the stage for some accumulating snow across southern sections of the region on Saturday.

A low-pressure system over the northern United States will track close enough to the international border to spread modest snowfall totals over the southern Prairies. Snowfall warnings are in effect in southwestern Saskatchewan ahead of Saturday’s storm.

The snow began in southern Alberta early Saturday morning. Precipitation will gradually spread through Saskatchewan during the morning hours, reaching Manitoba by Saturday afternoon.

Generally, the region can expect 5-10 cm of snow, with locally higher amounts possible. This won’t be a blockbuster snowfall, but accumulations will be deep enough—and winds blustery enough—to slow down travel and require a decent workout with a snow shovel.

Amounts drop off sharply toward the north. Regina, Calgary, and Winnipeg could see up to 5 cm of snow from this system, with little more than a dusting any farther north.

The system begins clearing out Sunday, largely ending by Monday morning except perhaps for a few wayward flakes in eastern Manitoba.

SUNDAY AND BEYOND: BITTERLY COLD AIR MOVES IN TO START THE WEEK

Arctic air will sink southward by the late weekend into early Monday, bringing parts of the Prairies their coldest temperatures since the depths of last winter.

Bitterly cold daytime highs at or below -20°C are possible for parts of Saskatchewan and Manitoba by Monday. Conditions will feel as cold as, or even colder than, -30 for some when you factor in the winds.

However, milder Pacific air looks to act as a bit of a spoiler at times over the coming days, and that will especially be true with this early-week blast of Arctic chill. While the eastern Prairies are set to shiver, Alberta and parts of southwestern Saskatchewan will be considerably less cold. Some parts of southwestern Alberta may even come within a stone's throw of 0°C.

Those who aren't ready for this kind of deep freeze yet can hang on until mid-week, when temperatures are set to rebound.
