Canada's Thanksgiving weekend forecast: You may need to plan ahead

The heaviest snow will occur through the day Friday with a slight shift in the storm track to the west.

"The greatest accumulations will likely be between the North Dakota border and Highway 1, between Brandon and Portage la Prairie where 50+ cm is possible through Saturday," warns Weather Network meteorologist Kevin MacKay. "Accumulations of 20-30 cm will extend westward into Saskatchewan and slowly diminish to zero in Regina."

Strong winds with gusts up to 60 km/h will also continue through Saturday with the strongest gusts of 80+ km/h picking up during the day on Friday. This will likely lead to blizzard conditions south of Lake Manitoba and along the Trans-Canada Highway.

"Consider postponing non-essential travel until conditions improve," Environment Canada says in the winter storm watches and warnings issued. "Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow."

Blizzard Info

Conditions will gradually improve in Manitoba on Saturday, although with winds still remaining gusty at times. At this point, Sunday will be the most ideal day to travel as quieter weather moves in.

HEAVY RAIN, STRONG WINDS IN SOUTHEASTERN MANITOBA, NORTHWESTERN ONTARIO

If the snow wasn't enough, east of Winnipeg and across northwestern Ontario, heavy rain will be the concern with the same system. That's as a mild southeast flow on the east side of the low will keep the region above freezing through the weekend.

"The heaviest rain will be through Lake of Woods where 50-70 mm is expected by Saturday, meanwhile less than 20 mm is expected east of Dryden and towards Thunder Bay, where locally higher amounts are expected along the Lake Superior shore," says MacKay.
