Record rain for Portland, 90-degree temperatures later this week

PORTLAND, Ore. (KOIN) — After receiving record rainfall on Sunday, Portland is forecast for 90-degree temperatures by Friday.

KOIN 6 Meteorologist Kelley Bayern says that an atmospheric river dropped 0.69 inches of rain on Portland Sunday, beating the previous record of 0.67 inches set in 2010. Portland is forecast for more cool, cloudy weather to start the week before the heat sets in.

“Monday and Tuesday remain cool and showery in the 60s,” Bayern said. “High pressure then builds to boost temperatures in Portland back into the 80s and 90s for the end of the workweek and the weekend.”

While daytime temperatures will see a 26-degree swing between Monday and Friday, Bayern reports that Portland isn’t forecast to break any temperature records.

“We’re not looking at record heat right now, but we’ll see how the forecast adjusts heading into the next few days,” Bayern said.
