‘Heat dome' over Ontario and Quebec causing wild weather across much of Canada
Blame the heat dome hanging over Ontario and Quebec for some of the strange weather hitting other parts of the country. Environment Canada meteorologist Julien Pellerin says scorching temperatures over the eastern part of the continent are causing below-normal temperatures in other regions, which have led to warnings of wet snow and heavy rain in the West. 'If you have a heat dome on a sector, you can expect colder air in another sector, so that's what the Prairies are currently experiencing,' Pellerin said on Sunday. 'It's coming from the United States, a high-pressure system that doesn't move quickly … so it brings intense heat and moist air over southern Ontario and southern Quebec and it'll settle there for the next three days.' The dangerous temperature levels span from southwestern Ontario towards North Bay, Sudbury and Timmins, while in Quebec the highest temperatures are expected from Montreal to Shawinigan and north up to Abitibi.

'By the end of Tuesday and Wednesday, we will have a transition in air mass all over Canada, especially over Quebec and Ontario.' In the meantime, the effects of the heat dome are bringing surprises to other parts of the country. On Saturday, Environment Canada warned that areas in British Columbia could face heavy showers, and over some of the highway summits, the possibility of wet snow. Meanwhile, heavy rainfall advisories that had been in effect in southern Alberta were all lifted by Sunday, but the region received significant precipitation. City residents were being warned to stay off the Bow River. The Calgary Fire Department advised against boating and all other water activities on the Bow due to higher-than-normal water flow, although the city said flooding over riverbanks was not expected. 'We know that Calgarians love their rivers, yet we also know that when our waterways flow this high and fast, there's significant risk to anyone, regardless of your watercraft or skill level,' Calgary Fire Deputy Chief Pete Steenaerts said in a news release. Story continues below advertisement Saskatchewan's Water Security Agency warned the Alberta rain could also lead to increased flows on the South Saskatchewan River between the Alberta boundary and Lake Diefenbaker. The agency said Alberta began dumping water from reservoirs this past week to make room for the additional run-off. It expected lake levels at Lake Diefenbaker, a large reservoir northwest of Regina that's a popular recreation area, to rise over a metre this week as a result of the weather system. Heat levels in Ontario and Quebec led Environment Canada to remind people to stay hydrated by drinking water before they're thirsty, to watch for early signs of heat exhaustion and not overexert themselves. 'Be careful; you know yourself,' Pellerin said. 'Make sure you're aware of what you're feeling and take breaks, Make sure you have a location where you can rest with the air conditioning.' In Quebec, schools are being urged to stay vigilant with the rising temperatures. In a letter from the assistant deputy education minister, schools were encouraged to 'put in place all the preventative measures you judge necessary to ensure everyone's security.' 'Depending on the situation, these measures could go all the way up to closing one or more schools for the day of June 23,' said the message signed by Stephanie Vachon.

Quebec to see scorching temperatures to start the week, says Environment Canada
Southern Quebec is bracing for a heat wave as a warm and humid air mass pushes through Ontario and makes its way across the province. Environment Canada meteorologist Julien Pellerin said the warmer temperatures will hit the Vaudreuil area as early as Sunday morning and will slowly spread across the Greater Montreal area through the day. By Monday, most of southern and southeastern Quebec will be affected by the air mass, Pellerin said, with temperatures reaching 30 C and above with humidex values between 40 and 45. "It's mostly the humidity in the air that will make it feel like really unbearable, if I can say, for some people," he said. The peak of the heat wave will hit on Monday and Tuesday with daytime highs expected to break records in Montreal, according to Pellerin. In an email to CBC he noted that the record for June 23 is 33.1 C and dates back to 2020, while the heat record for June 24 is 32.4, from 2003. Those expecting to get some relief overnight will be out of luck, with temperatures expected to remain above 20 C. Stay hydrated, Environment Canada warns And that is of concern, especially for people with chronic health conditions, older people and young children, Pellerin said, explaining that fatigue accumulates in the body and the warmer temperatures at night don't allow for recovery. With that in mind, the weather agency is reminding people to stay hydrated and drink lots of water, even before feeling thirsty. It is also recommending that people plan any outdoor activities for the coolest parts of the days and to limit exposure to sunlight and heat. To cool down, people can take showers and should try to spend a few hours a day in an air-conditioned or cool location. Meanwhile, those who work with people experiencing homelessness in the Montreal area expressed concern about how the heat wave will affect the unhoused. "Severe heat is a lot more difficult to manage. In some instances, it's because people don't recognize just how hot it is and how important it is to hydrate. And so we've got a challenge ahead of us in the next couple of days," said Sam Watts, the CEO of the Welcome Hall Mission. He added that heat waves are something the mission plans for every year, so they'll be ready to monitor people and keep them hydrated. There is, however, the added concern that Tuesday coincides with Fête Nationale which is a statutory holiday. That means places where people might go to seek out air conditioning like public libraries or malls might be closed. Philippe Massé, a spokesperson for the city of Montreal, said no special recommendations or measures have been issued yet, but that could change.
