Forecasters anticipate that more records will be broken this week.
“The large-scale weather pattern across the nation is not expected to change appreciably over the next few days, maintaining anomalous weather conditions across many areas,” the National Weather Service said in its forecast discussion on Sunday. “The historic Northwest Heat Wave will continue through much of the upcoming week, with numerous daily, monthly, and even all-time records likely to be set,” the National Weather Service said in its forecast discussion on Sunday.
Forecasters predicted that Seattle would reach 111 degrees on Monday, raising concerns because many homes in the city lack air conditioning. Scientists said the temperatures were “unheard of,” and the heat was so intense in parts of Washington that asphalt roads began to buckle. Gov. Jay Inslee (D) suspended COVID-19
limits at publicly-run cooling centers so residents could seek refuge.

The oppressive weather is linked to a heat dome, which is an unusual, slow-moving weather pattern that has parked itself over the Pacific Northwest, stretching from Washington up to British Columbia and over to parts of Idaho.
Scientists have long warned that previously unprecedented temperature spikes will only become more common and severe as climate change continues unabated, fueled by the world's continued reliance on fossil fuels
announced in January that 2020 would tie 2016 as the hottest year on record, capping the hottest 10-year period in history
