On 24 June, a heavy band of clouds associated with an extratropical cyclone is seen over the Eastern Pacific and Gulf of Alaska. Heat released in these clouds ended up in the cloud-free region over Western North America on 29 June, where a blocking anticyclone formed and caused the extreme heat.
Where did the Oregon heat wave come from?
The heat is originating from a ridge of high pressure, or “heat dome,” that’s parked in the northeastern Pacific west of British Columbia.
What is causing the excessive heat wave?
Heat waves are typically caused by “unusually strong, high pressure systems,” said Feldkircher. According to the Farmer’s Almanac, air from atmospheric upper levels is pulled downward and is then compressed, causing increases in temperature. The longer this high pressure system stays, the hotter the area becomes.
Is Oregon getting another heat wave?

Why is it so hot on the West Coast?
California is hot because it has a high-pressure climate caused by the coastal mountains and greenhouse gases. California gets a lot of sunshine and very little rain, which means it stays hot most of the year. The greenhouse gases also trap heat, so it stays hotter for longer periods.
Why is Pacific Northwest so hot?
Heat domes, or sprawling ridges of high pressure, are a staple of summertime. They bring copious sunshine and sinking air that heats up as it is compressed. This particular heat dome is unprecedented for its strength in the Pacific Northwest.
Is the heat wave due to climate change?
Scientists say climate change is making them more frequent. As much of the nation swelters under temperatures that have canceled outdoor sports, sparked wildfires and taxed the infrastructure keeping people cool, experts warn that heat waves will only get more common.
What was the worst heat wave in history?

Will Seattle get another heat dome?
As summer is just a couple months away, let’s get one thing out of the way: We’re likely not going to see another heat dome like we did last year. A lot of us are still feeling the burn of that event. But as Climatologist Nick Bond tells KUOW, that was more of a “freak event” which likely won’t be occurring annually.
