A storm currently out over the eastern Pacific will push inland across B.C. this weekend and will bring widespread accumulating snow to the Canadian Rockies then down into the western and southern Prairies by Sunday and Sunday night.
Computer models are still at odds in regards to the track, which will be critical for snowfall totals. At this point, I expect a heavy snowfall in the Canadian Rockies and a moderate snowfall from central and southern Alberta into southern Saskatchewan.
This same storm could end up turning into a major eastern U.S. snowstorm (likely missing Ontario/Quebec) later Tuesday into Wednesday. Too early to say if it will impact Atlantic Canada, though I suspect the blocking pattern will force the storm far enough to the south later next week.
Season snowfall tidbits...
I did a little research yesterday and found that Vancouver is averaging about 43 percent of normal snowfall up to this point and about 99 percent of the 19 cm fell from just one storm back in December. No measurable snow in January or February at the Vancouver International Airport. After a wet start, the winter certainly turned dry as expected.
I also found that the latest snowfall in Toronto (Pearson) brought the total to just over 92 cm for the season, which is very close to the normal of 91 cm through this date for the season.
