WEATHER: The Heat Dome Returns This Summer With Record Breaking Temperatures

Editors Note: 46 degrees celisus temperatures we’re assuming took place in the article during the heat dome under wild fire conditions and most of this “heat” captured in the dome was probably from forest fires caused by drying conditions of the heat dome itself.

Heat dome inflates over Western Canada, the harbinger of all-time warmth?

Editor’s note: This article is no longer be updated. Click here for the latest on the potential life-threatening heat wave impacting Western Canada.

A heat dome usually camps in the Four Corners section of the southwestern United States; instead, it will bubble up directly over British Columbia by Saturday — extending into the northern territories and Alberta.

This feature will be particularly perilous because it’s so rare in this part of the world. Sixty per cent of British Columbians do not own an air conditioner in their households.

A heat dome is colloquially known as an intense high-pressure system that features descending air that compresses and warms to record levels at the surface.

These features tend to be cloudless, as well; this setup is an excellent inhibitor for vertical motion that produces clouds in the atmosphere. Heat domes often sniff out regions in drought, and as the old saying goes, drought breeds drought.

Then you get a feedback effect. The warm air gets trapped in the lower elevations, and temperatures can only fall into the 20s at night. The following days can be incrementally toastier.

Despite a few setbacks, spring is indeed marching on – to the delight of people drawn to Canada’s wilds for a spot of camping.

But depending on how those proverbial spring showers shake out, the season’s rising temperatures also mean wildfire risk is once again a factor.

That’s where campers come in. While there are few greater joys in life than a good, roaring campfire, they can be a serious wildfire risk if not put out properly (in fact, human-caused wildfires make up more than half of the yearly total).

Watch the video above from Kyle Brittain, The Weather Network’s Alberta correspondent, for tips on how to safely extinguish a campfire.

Extreme Snowfall In British Columbia

Wintry conditions continue to plague B.C. after week of extreme cold, snow

LINK: https://www.cbc.ca/news/canada/british-columbia/wintry-conditions-continue-to-plague-b-c-after-week-of-extreme-cold-snow-1.5432116

After a week of winter weather that walloped much of B.C., some parts of the province are getting a reprieve — others, not so much.

A snowfall warning is in effect for the Fraser Canyon, with 10 to 20 centimetres expected. Freezing rain is expected on the Coquihalla Highway between Hope and Merritt, and for Highway 3 from Hope to Princeton.

A winter storm warning is in effect for the Fraser Valley, including Chilliwack, Hope and Abbotsford.

Total snowfall accumulations could range from five to 10 centimetres. As conditions warm up, that snow could transition from snow, to freezing rain, and then to rain.

A wind warning is in effect for Greater Victoria, North Vancouver Island, and the Southern Gulf Islands, with southeastern gusts of 60 to 80 kilometres per hour expected. Thousands on Vancouver Island are currently without power as a result of the windy conditions.

A winter storm warning is also in effect for east Vancouver Island, from Courtenay to Campbell River, Duncan to Nanaimo, and Nanoose Bay to Fanny Bay. Heavy, wet snow is expected to turn to rain early on Saturday.

A winter storm warning is in effect for the Sea to Sky from Squamish to Whistler, bringing a mix of weather from heavy snow, to freezing rain, and blowing snow. Squamish could get up to 20 centimetres of snow.

Environment Canada is urging people to consider postponing non-essential travel until conditions improve.

Armed Forces to help Newfoundland residents after province records unprecedented levels of snow

ST. JOHN’S, N.L. — Armed Forces personnel were deployed Sunday to help Newfoundland and Labrador dig out from the monster blizzard that paralyzed eastern regions of the province with record breaking amounts of snow, as forecasts called for yet more precipitation overnight.

Premier Dwight Ball asked for Ottawa’s help on Saturday, as residents of St. John’s and other communities on the Avalon Peninsula awoke to drifts that blocked doorways and clogged roads.

Heat Dome Engulfs Europe, Spreading To Canada

The Heatwave in Europe caused by a large “Heat Dome” is also spreading to Canada and causing a massive heat wave.

A Giant ‘Heat Dome’ Over Europe Is Smashing Temperature Records, And It’s on The Move

ANDREW FREEDMAN, THE WASHINGTON POST

A historic heat wave is bringing unprecedented temperatures to Western Europe, and is poised to expand northeastward to Scandinavia and into the Arctic by late this weekend.

Once above the Arctic Circle, the weather system responsible for this heat wave could accelerate the loss of sea ice, which is already running at a record low for this time of year.

First, residents of Paris, London, Brussels, Amsterdam, Munich, Zurich and other locations are suffering through dangerously high temperatures on Wednesday and Thursday.

Already on Wednesday, all-time national heat records in the Netherlands, Belgium and Germany had fallen, right on the heels of a late June heat wave that broke similar records in France and other countries.

The German meteorological agency noted that Wednesday’s national record of 104.9 degrees Fahrenheit (40.5 Celsius) may last just a day before being broken on Thursday.

It’s difficult to beat all-time heat records in mid-July, considering this is the hottest time of year. It’s even more unusual to beat these records by a large margin, which is what is occurring now.

For example, Paris is likely to exceed 100 degrees Fahrenheit (37.8 Celsius) on Wednesday by a few degrees, and break its all-time high temperature record of 104.7 degrees Fahrenheit (40.4 Celsius) by up to 3 degrees Fahrenheit on Thursday, with a forecast high of 108 Fahrenheit (42.2 Celsius).

The city’s all-time high temperature record has stood since 1947.

Multiple all-time records were set elsewhere in France on Tuesday, both for daytime highs and hot nighttime low temperatures.

The UK Met Office is predicting that the country’s all-time national heat record of 101.3 degrees Fahrenheit (38.5 Celsius) will be broken Thursday.

In addition, national heat records in Germany, where the mark to beat is 104.5 degrees Fahrenheit (40.3 degrees), could be set this week as well.

Heat of this intensity constitutes a significant public health threat, particularly for vulnerable populations like outdoor workers, the elderly, young children, those with compromised immune systems and anyone lacking the means to cool down.

In most of the cities currently affected, people lack air conditioning at home and in many public buildings and transit systems.

There have been 15 heatstroke deaths of children left in hot cars in 2019. And it’s not even July.

Fifteen children have died from heatstroke in the USA this year as a result of being left in hot cars – and it’s not even July.

Three of the deaths occurred since last Saturday, and extreme heat is likely in the South and parts of the Midwest on Sunday heading into the Fourth of July.

The latest hot car death came Thursday evening in Morristown, Tennessee, when a 3-year-old boy was found in a minivan after he had been reported missing since 4 p.m. The temperature had reached 90 degrees.

“Officers found the child deceased on the floorboard of a minivan that was parked on the property,” the city of Morristown wrote in a statement on Facebook. “Investigators believe, at this time, the child entered the vehicle without anyone knowing and became trapped.”

Toxic Air Closes Schools In Thailand

Bangkok shuts hundreds of schools as some of world’s most toxic air shrouds city

(Bloomberg) — Thai officials shut hundreds of schools in Bangkok on Wednesday as some of the world’s most toxic air hung over the city.

The metropolis of about 10 million people closed 437 government schools until Friday, its local authority said, prompting private institutions to follow suit. The air quality index, or AQI, was around 170 in the afternoon, the fourth-worst major urban reading globally, according to data from AirVisual, which tracks pollution levels.

Prime Minister Prayuth Chan-Ocha, leader of Thailand’s military government, said he’s seeking temporary closure of some factories during pollution spikes to tackle the problem. He added that he’s ordering soldiers to inspect and report back on the worst polluters.

“In the short-term, shutting down factories may mean accepting some economic damage, but protecting public health must be the utmost priority,” said Kakuko Nagatani-Yoshida, the UN Environment Programme’s regional coordinator for chemicals, waste and air quality.

Global News – https://globalnews.ca/news/4907009/polar-vortex-canada/

Extreme cold has gripped much of Canada thanks to a hovering polar vortex.

Large swaths of the country are under extreme cold alerts. Stretching from Saskatchewan through Manitoba and northern regions of Ontario and into Quebec, temperatures dipped south of -50C with the windchill Wednesday. And it’s not over yet.

“This polar vortex is expanding out to include more of North America on Thursday,” said Global News chief meteorologist Anthony Farnell.
