Rain, snow clears the air in Oregon after the hottest and driest fall on record

Friday will feel like a weather shock for many Oregonians.

In place of the daily sunshine, hot temperatures and smog, the cold rain and mountain snow that usually defines Oregon in late October returns.

What meteorologists describe as a “pattern change” will begin Friday, bringing several inches of rain to the Willamette Valley and 2 to 4 inches of snow in the passes of the Cascade Range through Saturday and Sunday.

The reason for this change is simple – the ridge of high pressure that has been pushing the Pacific storms north and south is breaking down as the jet stream of moisture moves through it, bringing wet conditions over the next few weeks.

“It’s a wholesale change, and while no single storm produces a ton of rain or snow, it’s something that tends to increase over time,” National Weather Service meteorologist Colby Neumann said.

Smoke from nearby wildfires reduced air quality in the Willamette Valley and downtown Eugene on Monday, October 10, 2022.

The rain is reducing and clearing the air two wildfires that have been producing smoke and poor air quality – the Cedar Creek Fire and the Nakia Creek Fire.

Rain will begin Friday and continue Friday evening. A half inch to an inch and a half will fall in the Willamette Valley over the weekend, and 1 to 3 inches in the Cascade foothills and Coast Range.
