Parts of Alberta have seen a wintry setback, putting a halt to spring with an extended period of snow this weekend. The snow will continue Sunday, with the heaviest totals in the foothills of Alberta, though populated places such as Calgary and Lethbridge will see a dusting of snow, as well, before it finally tapers in the evening. Snowfall warnings are still in place. More details, along with a look ahead to milder weather, below.
SUNDAY: SNOW CONTINUES, TEMPERATURES DIVE
Much of Sunday will be snowy and frigid across parts of Alberta. It has been a somewhat long-lasting event through the weekend. A weak, but persistent, upsloping flow will help keep the snow falling through the afternoon hours.
As well, a secondary area of low pressure has now formed south of the border, which is helping to beef up snowfall totals along the eastern slopes of the Rockies, in addition to the upslope enhancement.
Additional accumulations will be focused along the foothills, with the threat for 10-15 cm by the time the snow finally diminishes. Snowfall warnings are in effect.
The Calgary area may see about 5 cm Sunday, enough to catch some drivers off guard and make for tricky travel at times throughout the weekend. 5-10 cm is expected for areas just west of the city.
The light snow will also track east of Highway 2, drifting into Saskatchewan Sunday. The snow will gradually diminish by Sunday evening.
Temperature-wise, Sunday's daytime highs will hover around the mid-single digits for much of southern Alberta, though slightly less for Calgary, and a few degrees warmer in northern Alberta and elsewhere in the Prairie region.
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.
