Frigid air descends back over the Prairies, bursts of late April snow

After basking in another round of astounding late spring-like warmth on Wednesday, temperatures took a fast and steady tumble early Thursday as an arctic front pushed through the western Prairies, changing all of the overnight preciptation to snow. Snow totals will be generally light through the foothills, though with locally heavier amounts in the Rockies. More on how much to expect and the next reinforcing shot of cold air for the weekend, below.

THURSDAY: TEMPERATURES DROP, SNOW PUSHES IN

Similar to what happened last weekend, the late-spring warmth that graced the region to start the week will quickly disappear thanks to the arctic front that sent temperatures rapidly plunging. As the system sinks further south, and with the much cooler air in place, bursts of snow are also expected to develop.

Flurries will set up across the Edmonton area Thursday morning. A band of snow is then expected to push into Red Deer, Calgary and eventually further south by the afternoon hours.

Snowfall amounts will be highly terrain-driven with upslope enhancement -- giving way to locally heavy accumulations along the Rockies and southern foothills. Between 5-15 cm is possible in these regions. Areas along Highway 2, however, are likely to get closer to 2-5 cm, but areas just a few kilometres west could get amounts in the 5-10 cm range.

After the passage of the system, winds will increase and switch to a north-northwest direction. Gusts between 50-60 km/h are possible, even hitting 70 km/h in southern Manitoba, delivering a chilly air mass to the region.

More noticeable will be the temperature nosedive on Thursday, possibly dropping by as much as 20 degrees in Calgary in comparison to Wednesday's balmy highs. There will be quite a contrast in temperatures across the Prairies, as Winnipeg will be approaching the 20-degree mark.

BEYOND: CHILLY CONDITIONS SPREAD EAST, REINFORCING SHOT OF ARCTIC AIR

Colder weather will continue to spread east for Friday, with temperatures only reaching 1°C for Winnipeg. A reinforcing shot of arctic air will push in on the weekend, with as much as 5-10 cm possible for southern Alberta, including Calgary on Saturday afternoon.

"Milder weather gradually returns to southern areas next week, but northern areas remain on the cool side of seasonal until the middle of next week," says Dr. Doug Gillham, a meteorologist at The Weather Network.
