The heat wave was caused by what meteorologists described as a dome of high pressure over the Northwest and worsened by human-caused climate change, which is making such extreme weather events more likely and more intense.
What is causing the heatwave in the Pacific Northwest?
The Pacific Northwest temperature spike was caused by what scientists call a “heat dome”, or a mass of high-pressure air parked over the region. Like a lid on a pot, the dome trapped hot air beneath it. “This event was shocking to everybody who experienced it in the Pacific Northwest.

It’s coming! Summer temperatures are predicted above-normal for about two-thirds of the country, especially in the South and East. While typically the hottest weather can be expected in late July or early August, this year’s summer heat could peak in late August, into early September.
Why is it still hot in October 2021?
Higher temperatures this week are in part caused by a high pressure system spreading across the South up through New England — calling for more sunshine and warmer weather. Recent rain and snowstorms on the West Coast created the high pressure system, Gartner said.
