Whoops, she’s doing it again.
Wednesday: A couple of places in the south Willamette Valley could hit 90.
Thursday: A number of places in the valley and the Portland-Vancouver metro could hit 90. A lot of upper 80s, too.
Friday: Bring it. Many places, and likely Portland, make it to 90 degrees!
How Late In The Year Can Portland Hit 90
The latest ever, as you can see here, is October 5th. But four of the last five years it has happened during mid-late September. And guess what? The forecast models I use are hinting at another possible 90 degree visit the weekend of September 15-16. That’s a long ways out…it’ll probably rain that weekend instead. But just in case…you heard it here first!
