The snowfall over the weekend in southern Manitoba, which came after a three-day snowstorm, ended just in time … for more snow.
Environment Canada’s forecast predicts more snow on Tuesday with more certainty on Wednesday, but that’s just the beginning.
The Meteorological Agency is monitoring another low-level tracking of Colorado to Manitoba this weekend – the same type of weather system that brought in piles of snow last week
“We’re not sure if it will bring snow or rain, or icy rains, or all of them. At the moment, we just don’t know yet. It’s not clear enough,” said Environment Canada meteorologist Dave Carlson.
“But what it looks like is that there will be a lot of moisture in this system. Almost all forecast models point to 25-40 millimeters of water equivalent, whether it fell like snow or rain over much of southern Manitoba.
“So, yes, more moisture is coming.”
The system, which is expected to hit almost everywhere in Manitoba south of the Great Lakes, is expected to enter on Friday and stay over the weekend before heading to northwestern Ontario on Sunday.
A spring snowstorm, which officially reached blizzard levels in parts of western Manitoba, erupted somewhere between 13 inches northwest of Winnipeg and 82 inches south of Riding Mountain last week. Winnipeg received 25-35 cm.

The sun appeared for a brief sporadic appearance on Saturday before retiring on Sunday to allow snow to build up again.
In general, they fell about 8-10 cm, although higher altitudes in the southwest probably got more, Carlson said.
“I expect the mountain turtles probably got more, maybe 10 to 15 centimeters, but I have no confirmation of that,” he said.
Late spring snow is not unheard of in Manitoba. The long weekend of Victoria Day, considered the unofficial start of the summer and camping seasons, has been covered in snow in the past.
But it’s abnormal to get so much, Carlson said.
“We usually get a system that carries a decent amount of snow, 15 or 20 centimeters, not one after the other – not like we had this year, that’s for sure.”
The snow layer also keeps temperatures below normal. The average maximum temperature for this time of year is 12 C, and the forecast a few days ago – when the people of Manitoba were looking for hope to overcome the snowstorm – suggested that it could reach 8 C on Monday.
And what happened?
“The temperature is higher in the atmosphere [and] usually that would mean eight degrees down here, but it’s true [the forecast model] it didn’t catch that we have such snow cover here and it modulates it so much, “Carlson said.
Instead, the highest temperature for Monday is expected to be 1 C. The same for Tuesday and the same for Wednesday.
“At this time of year, you can get really, really wild temperature changes. So that’s not very, very strange in itself, but the only thing we’re looking at is that tonight, in Winnipeg, for example, we’re forecasting lows of -16 degrees Celsius, “Carlson said.
“Our record low for this date is -12 C.”

The normal low for this time of year is 0.
“So, yes, that [Monday low] it’s especially cold at this time of year, “Carlson said.
Temperatures are expected to rise slightly by the end of the week, so it is currently unpredictable what type of rainfall will bring low in Colorado.
Winnipeg usually has an average of 127 cm of snow in the winter, but so far it has been hit by 212 cm this winter, making it the sixth snowiest in history as of April 17.
If the incoming humidity falls like snow, it could bring the total closer to third or even second, according to retired Environment Canada meteorologist and weather historian Rob Paola, who runs the popular Twitter account @robsobs.
With another 9 cm of snow yesterday, the seasonal snowfall in Winnipeg now stands at 212.0 cm, the 6th snowiest winter in history as of April 17. The extra snow this week will probably take us to 3rd or 2nd place by the end of the week < a href="https://t.co/VT4vj6smZr">pic.twitter.com/VT4vj6smZr
