Winter storm warnings have spread to eastern Prairies and northern Ontario as the effects of a major spring storm begin to move later Tuesday night. This long-running snowfall will last until Friday, potentially going down in history as one of the worst snowstorms in decades. People are now being asked to prepare for extensive and significant travel, electricity and school holidays and are encouraged to stock up on supplies and medicines before the storm closes. Until it is finished, some spots may appear up to 75 cm of snow, with a potentially dangerous and almost impossible route. More about the schedule and what you can expect in the coming days, below.

At an all-time low, temperatures well below normal will create the ground for a major blizzard in southeastern Saskatchewan, southern Manitoba and northwestern Ontario in the second half of this week.
On Tuesday there will be single-digit prices in Manitoba, temperatures you would not expect just before a major snowstorm.
The Colorado low will intensify rapidly as it heads toward the Midwestern United States and eventually reaches Manitoba and northwestern Ontario. This will be a subversive system south of the border, with the threat of snowstorms in the northern plains and several days of strong thunderstorms in the southern half of the Plains and the states of the Far South.
The snow will start early Tuesday afternoon near the international border and then push north throughout the night. By Wednesday morning, heavy snowfall will fall in much of southeastern Saskatchewan, southern Manitoba and northwestern Ontario as the storm continues to push north. Snowfall rates will continue to rise, with possibly a few inches per hour at times.
“As the heaviest snowfall zone rises north on Wednesday, snowfall rates may temporarily decrease later in the day for the southern regions, but then the snowfall rates will rise again on Thursday and will be widespread in all southern parts.” , warns Kelly Sonnenburg, a meteorologist at The Weather Network.
Strong north winds will develop and persist until Friday morning, as the low will rotate slowly in Minnesota in northwestern Ontario.
It forms into a historic high-impact storm with heavy snowfall and gale-force winds that could lead to periods of calcium conditions for many areas. Winter storm watches were upgraded to winter storm warnings and blizzard warnings first thing on Tuesday.
The possibility of reduced visibility and white light conditions will significantly disrupt travel along a section of the Trans-Canada Highway on the Canadian side of the border as the day progresses on Wednesday. The extensive closure of highways is almost certain. Until Wednesday afternoon, even commuting within communities may become impossible as heavy snow and strong winds continue. More on the same is expected on Thursday.
“Do not plan to travel – this storm has the potential to be the worst blizzard in decades,” Environment and Climate Change Canada said in a winter storm warning. “Save the supplies and medicines now.”
Power outages are possible and rural areas should be prepared for extended outages. Also, school cancellations are also almost certain.
Widespread sets of 20-40 cm are possible, with some spots possibly collecting up to 50-75 cm of snow. However, it can be difficult to measure the exact amount of snowfall due to natural and drifting snow. The wide range and slow motion of this storm means that it will be a prolonged snowfall, with snow lasting up to 48 hours in some areas.
The heavy snowfall accompanied by north winds of 70-90 km / h, will give almost zero visibility at times.
By Friday the snowfall will subside, but the winds will remain strong with gusts of 50-70 + km / h – and remind that you do not need snow to create a blizzard. The winds will start to weaken on Friday afternoon.
On Saturday, there will be occasional stormy winds, while by Sunday the conditions will finally be much calmer.
“There seems to be a favorable temperature trend beyond this system to help with flood concerns, with daytime highs projected to remain below zero until at least the middle of next week,” Sonnenburg added.
