More than 150 million people across the United States are under some form of heat alert for Tuesday or the coming days, with temperatures soaring from the parched and smoky West, to the Great Lakes and the Plains, and the Mid-Atlantic and Northeast.
Most of Washington State, 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.
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.
Stifling heat will also be found across portions of the Great Lakes region, the Mid-Atlantic and the Northeast early in the week, the Weather Service said. High temperatures are forecast to reach into the 90s, with the heat index — a measurement that combines heat and humidity — approaching 100 degrees.
By midweek, temperatures in Spokane, Wash., are expected climb into the lower 100s, and possibly reach 109 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 of up to 105 degrees or higher 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 110 degrees over the next few days.
