Dangerous heat gripping the Pacific Northwest
A heat wave is gripping the Pacific Northwest with some temperatures soaring higher than 100 degrees in some areas. FOX Weather meteorologist Steve Bender has the latest.
PORTLAND, Ore. - Mother Nature is beginning to crank up the temperatures in the Northwest.
A ridge of high pressure has started a warming trend across the region, with highs expected to reach well into the 90s and 100s across much of Oregon and eastern Washington through midweek.

"When we look at the air temperatures for today, if you thought yesterday was hot, it's going to be even warmer (Tuesday) afternoon," FOX Weather meteorologist Steve Bender said. "You're going to get those temperatures in Portland of 102 degrees."
That means widespread triple-digits across Oregon. Portland and Eugene are forecast to reach 100-102 degrees, while it's likely to reach 103 in Bend, 105 in Pendleton, and well over 100 across Washington's Columbia Basin.

The triple-digit temperatures will also extend into Idaho, where Boise is expected to reach 102 degrees late Tuesday afternoon.
STYLISH VS. PROTECTION: WHAT TO KNOW WHEN CHOOSING YOUR NEXT PAIR OF SUNGLASSES

Even Seattle gets in on the heat with highs reaching the low to mid-90s from Tuesday through Thursday, which for Tuesday is threatening the daily high-temperature record of 92, set in 2018.

About the only place to find relief is along the Washington coastline and islands, where highs are expected to remain in the 70s to low 80s.
The heat is expected to last several days – all the way through the end of the week.
"This definitely is going to be prolonged — we're looking at five days with temperatures above average," FOX Weather meteorologist Britta Merwin said.
There is one forecast wrinkle: Wildfire smoke
Unfortunately, with this heat comes a potential for hazy skies, thanks to large wildfires burning in California.
Forecast models now suggest the possibility of smoke from the Oak Fire and Washburn Fire near the Sierra Nevada mountains may be carried north into western Oregon on Tuesday.
"While (smoke is) not expected at the surface, if dense enough aloft, it could block some of the solar radiation and thus, keeping things slightly cooler," forecasters with the National Weather Service office in Portland said. "This effect is challenging to forecast, so will have to keep tight weather watch on that."
The heat is expected to wane as the week nears its end, with cooler but still above-average temperatures expected to hold through the weekend.
No rain is expected across the Northwest for the next 7-10 days.
