National Weather Service

Virtually every part of Oregon has one or more National Weather Service notices set for this weekend.

An early-season atmospheric river is forecast for Oregon this weekend.

A low pressure system will bring large waves for Friday afternoon through Saturday.

An inch or more of rain is expected across central and western Oregon by the end of the weekend.

Although it may have smelled strongly of smoke Thursday, National Weather Service Meteorologist Colby Neuman said air quality in Eugene saw highs in the “moderate” range.

A heatwave has hit much of western Oregon. In the Willamette Valley, an “Extreme Heat Warning” is now in place through at least Tuesday evening.

Highs are expected in the upper 90s to lower 100s for the Southern Willamette Valley Friday through Monday.

Forecasters say an atmospheric river will bring up to half an inch of rain to the Eugene area over the coming days, with northern Oregon expected to see up to three inches.

The National Weather Service projects temperatures to remain in the high 90s or above 100 in large swaths of Oregon on Tuesday before a big cool down.

Triple-digit temps are expected along both sides of the Oregon Cascades, and stretching east to the John Day Basin and Blue Mountains.

Warmer-than-normal high and low temperatures expected in the coming days.

As much of Oregon endures consecutive days of high heat, climate data shows the state has seen more 90 degree Fahrenheit or hotter days over the past 10 years than in the decades that came before.
