The NewsEven as it continues to swelter, the South may get a break from steamy weather this week while the Northwest bakes in some of the highest temperatures people there will endure all summer. It isn’t unusual to get a day or two of 100-degree heat in places like Portland, Ore., but three days in a row this late in the season is uncommon, said Clinton Rockey, a forecaster with the National Weather Service in Portland. According to Mr. Rockey, only about 40 percent of the people in northwestern Oregon have air-conditioning, which can be troublesome, especially when the low temperatures at night are expected to also break daily records for heat. The duration of this heat wave, which began on Sunday, and the high overnight temperatures are also a big concern for Matthew Cullen, a Seattle-based forecaster with the Weather Service who said there have been only a few hot days in his region this summer and no significant stretches of heat like this one, which could last at least until Thursday. While the heat is dangerous, Mr. Cullen doesn’t expect this to be anything like the heat wave of June 2021.
