Weather forecasters say temperatures in the Pacific Northwest will rise to triple digits in some cities after several days of extreme heat before returning to heat over the weekend. Some easing is expected this week.
Portland, Oregon, experienced a week-long heat wave, with daily highs reaching 102 degrees Celsius on July 26, said Lisa Kriederman, a meteorologist for Portland’s National Weather Service. On Sunday, in Portland, she had temperatures above her 95 degrees Celsius for the seventh straight day, breaking her previous record of six straight days.
Temperatures were above 90 degrees Celsius for the eighth straight day, still below the 10-day record in 2009.
Temperatures in Portland also haven’t hit last summer’s record of 116 degrees Celsius, but the recent heat wave is on the mend. Cool air from the coast keeps moisture levels high and temperatures don’t rise as much. Kriederman said this compared to last year when Portland was coming from the central Oregon area where the air was drier.
“It hasn’t been that hot, but we’ve had a long run of above-average temperatures,” she said.
The region is expected to cool down through Thursday and warm up again over Friday and over the weekend, Kuredermann said. Highs are expected to be 87 degrees on Tuesday, 86 degrees on Wednesday, 78 degrees on Thursday and 83 degrees on Friday. According to the Japan Meteorological Agency.

In Pendleton, Oregon, about 200 miles east of Portland, temperatures hit 111 degrees on Friday, said Larry Nierenberg, a meteorologist at Pendleton’s National Weather Service. By Sunday, Pendleton had recorded temperatures above 100 degrees for seven days, he said.
Smoke from the McKinney wildfires in Northern California pushed temperatures in Pendleton down from 110 degrees on Saturday to 101 degrees on Sunday. According to Nirenberg, wildfire smoke acts like a cloud, blocking the sun from coming through for several hours.
A similar pattern was seen in the cities of Kennewick, Pasco, Richland and West Richland in southeastern Washington state, with Friday highs of 112. The temperature has been above 100 degrees Celsius for 8 days in a row. A heat advisory was in effect for the region as of Monday afternoon.
Temperatures in Pendleton and throughout southeastern Washington were about 10 to 20 degrees above normal over the past week, Nirenberg said, with temperatures in the high 90s in Pendleton and slightly higher in the city.
In eastern Washington and the Idaho Panhandle, average July temperatures were not on record, said Daniel Butler, a meteorologist at the National Weather Service in Spokane, Washington.
But Spokane reportedly hit or surpassed 100 degrees Celsius for the fourth day in a row. In 1928 he set the record for six consecutive days with temperatures above 100°C.
Butler said the recent heatwave hasn’t brought the hottest days on record, but it’s been hotter for longer.
“It’s been pretty impressive, the longevity of this event,” he said.
