Seattle’s second-longest dry streak on record ended late last week when light rain fell for the first time in 51 days. But the region is expected to once again bake under an intense heat wave this week, meteorologists said, with triple-digit temperatures amid the already dry conditions.

Most of Washington, western Oregon and parts of Northern California — including near where the Dixie Fire is burning — will be under an excessive heat watch this week, according to the National Weather Service. That means temperatures could be hot enough to trigger heat stroke and other medical issues.

“It’s going to be a real oppressive week with dangerous heat and hot conditions,” the Weather Service tweeted.

It’s going to be a real oppressive week with dangerous heat and hot conditions. Excessive heat watches are up across much of the Pacific Northwest. Meanwhile, heat advisories are in effect for a good part of the south-central U.S. and parts of western New York state. #heatsafety pic.twitter.com/2823gpKne8

Temperatures in Spokane, Wash., are expected to reach the low 90s on Monday and climb into the lower 100s by midweek and possibly reach 108 degrees by Friday. Areas around southwestern Oregon and Northern California are expected to see similar conditions, with temperatures forecast to hit the lower 100s from Tuesday through much of the week.

While temperatures in the region won’t be as high as they were in late June and early July, when a heat dome killed hundreds in the Pacific Northwest, they could still have negative health effects.

The center of the United States, from Iowa and Nebraska down to parts of Louisiana and Texas, will be under a heat advisory through Thursday, the Weather Service said.

Heat indexes — a measurement that combines heat and humidity — of up to 106 degrees are expected for portions of Missouri, Iowa and Illinois. “Hot temperatures and high humidity may cause heat illness to occur,” meteorologists said. Temperatures in Tulsa, Okla., could feel more like 113 degrees over the next few days.
