TORONTO – Seasonal or increased than regular temperatures throughout much of the nation will supply Canadians an opportunity to benefit from the summer, however predictions from a outstanding nationwide forecaster warn the humidity might welcome a relatively stormy few months.
Chris Scott, chief meteorologist at The Weather Network, says the warmth coupled with an energetic jet stream will lead to above regular precipitation that runs throughout the Prairies by means of to Ontario and Quebec.
Whereas that “doesn’t imply on daily basis goes to be a wash-out,” Scott says he expects “some relatively intense storms from time to time.”
Scott says Western Canada isn’t shaping up to face the identical situations that led to final 12 months’s devastating warmth wave and wildfires in British Columbia.
The westernmost province is predicted to regularly emerge from a cool spring and into near-normal temperatures beginning in June, which he says will drag out the snow soften and gradual the beginning of wildfire season.
Throughout the Rockies, the extremes of springtime dryness in Alberta and floods in Manitoba will start to even out, he stated, as precipitation throughout the Prairies returns to extra regular ranges.
Nevertheless, he famous the risk of drought situations lingers in southern Alberta, which could possibly be influenced by the “epic warmth” anticipated to grip areas simply south of the border.

“We’ll have to watch precisely the place that big warmth dome units up,” he stated.
“This does set the stage for thunderstorms … We are able to get big hail, big wind within the Prairies and we expect this summer truly has a reasonably good likelihood of having a number of extra of these big storms than regular.”
In Ontario and Quebec, most of the area is probably going to expertise a “very heat and humid summer” that doesn’t fairly contact the degrees of final 12 months’s sweltering June.
“We’re going to see rather a lot of heat climate, rather a lot of dry days,” he stated, forward of the beginning of the meteorological summer on June 1. The official begin of summer is June 21.
“However after we get the setups for precipitation, simply be further vigilant this summer as a result of we expect these storms can actually pack a punch.”
Scott doesn’t anticipate a duplication of the “extraordinarily uncommon” extreme wind and thunderstorm that swept by means of Ontario and Quebec on Might 21, however he urges Canadians – significantly campers – to be vigilant when it comes to fast-moving climate patterns.
The Atlantic provinces can count on above regular precipitation and above regular temperatures. These elements recommend a really energetic hurricane season within the area, he stated.
“We are able to’t say precisely what storms do what; seasonal forecasts are a sketch,” he stated.
“But it surely’s a heads up for those who’re in Halifax or Yarmouth – wherever you might be in Atlantic Canada and admittedly again to Quebec and Ontario. Bear in mind of the state of affairs, particularly into July and August with the development for tropical storms and hurricanes.”
Temperatures must be beneath regular in Yukon and Nunavut, whereas precipitation stays shut to regular.
Round Hudson Bay, he stated to count on above regular precipitation.
Scott famous that whereas excessive warmth eventualities are on the rise and can proceed in that route.
“We all know that our local weather is warming; that’s unequivocal,” he stated.
“Science tells us that the world is warming as a complete and Canada’s local weather is warming. So any occasion that may be tied to that – like a warmth wave that we noticed final 12 months in B.C. – that’s made extra possible in a warming local weather.”
Some of the current phenomena round excessive climate occasions, akin to extreme thunderstorms, are tougher to predict, he added.
“We’re getting extra warmth waves, completely 100 per cent. We’re additionally getting much less extreme chilly spells,” he famous.
“In between, you’ve acquired this combine of heavier rainfall, however then what’s occurring with extreme wind and hail and tornadoes? We don’t actually know in that space. We might by no means as a result of it’s a really advanced half of climate.”
