Record-setting, dangerous heat continued Monday in Portland. The good news? Monday should be the final brutally hot day, for now.

Cooler, but still hot, air was expected to make its way in from the coast beginning Monday night, according to the National Weather Service. The system that had been holding torturously hot temperatures over the Pacific Northwest was expected to shift east of the Cascades by Monday evening.

Overnight low temps Sunday dropped very little. Some locations may see records for warmest overnight low broken for this date.

This made for a very warm start to what would likely be another record-breaking day. Most locations across the central Willamette Valley and northward into Southwest Washington saw another day in triple-digit heat.

The rest of the week will feel relatively “cool” in Portland as high temperatures will lower into the upper 80s to low 90s.

Strong onshore winds, with some gusts up to 30 mph, will help bring the cooling air into the valleys Monday night and into Tuesday. Highs will be near 92 degrees under sunny skies.


The exception may be the central Columbia River Gorge and Hood River valleys as models are showing the heat lingering in those areas and temperatures remaining in the low 100s.

By midweek, Portland should see its first day in the 80s since the middle of last week. Skies will be sunny and temperatures should drop to about 88 degrees Wednesday.

Although Portland will see temperatures lower back down to more agreeable 80s and 90s, central and eastern Oregon will continue under extreme heat warnings well into the week.
