Regenerating heat dome is forecasted for the northwestern USA and neighboring Canada minimally until the end of July 2021, with the result of the next historic heatwaves, when all-time records are falling and extensive wildfires are spreading.
Heatwaves will be shifting from the northern Rocky Mountains into the Midwest, the Great Lakes region, and in a short time even to the Northeast in the next decade (the 3rd decade of July 2021).
In Montana, the coldest US state excluding Alaska, on Monday, 19. July 2021, 110°F / +43°C in Glasgow was measured. The all-time state record from 1937, 117°F / +47°C although hasn´t been overcome, but at many stations were broken all-time temperature records according to coolwx.com.
A similar situation is persisting across the Rocky Mountains, parts of western Canada, and the partially western coast of the USA for several days, with the result of many extensive wildfires across the western half of the USA and Canada.
Smoke from wildfires in Canada has moved over 1000 miles away, above Mid-Atlantic, the USA.
67 weather stations in the USA have already recorded their all-time hottest temperatures in 2021.
The destructive Bootleg Fire, one of the largest in modern Oregon history, has already burned more than 476 square miles, an area about the size of Los Angeles according to https://www.staradvertiser.com/.
“Unpredictable winds, fire clouds that spawn lightning, and flames that leap over firebreaks are confounding efforts to fight the blaze, which is sweeping through southern Oregon.”, is describing Bootleg wildfire a New York Times – a system is creating its own weather.
Wildfires are every year the worst at the end of summer and at the beginning of autumn, therefore it´s very possible, that the worst in the western USA and Canada is only coming.
