Heavy rain to soak Oregon's Willamette Valley, foothills with some snow on Cascade passes

People walk with umbrellas as rain falls in Salem in 2019. Another round of heavy rainfall will hit Oregon over the next few days, but it’s probably not enough to bring flooding, said National Weather Service meteorologists.

Another round of heavy rainfall will hit Oregon over the next few days, but it’s probably not enough to bring flooding, said National Weather Service meteorologists.

Around 1-2 inches of rain is forecast to soak the Willamette Valley and foothills Friday to Sunday, while the mountains could get 2-4 inches.

The highest mountain passes could see 3-6 inches of snow, but it’s not expected to bring a whiteout or serious travel impacts.

NWS meteorologist Rebecca Muessle said the system of rain isn’t an atmospheric river, but rather a particularly juicy front coming in from the south.

“It’s bringing a lot of moisture and is pretty warm, but it’s fast moving and isn’t taking on the structure of an atmospheric river,” she said.

Muessle added that while rivers will rise, flooding isn’t expected to occur, largely because of how dry Oregon had become following a “flash drought” that sucked the soil dry during April.

“The rivers will bump up, but right now we’re only seeing a 5% chance that rivers even make it to ‘action stage,’” she said.

Overall, this is just a helpful hit of rain for water supply, irrigation, gardens and wildlife before drier weather returns later next week. The eight to 14 day forecast shows warmer and drier conditions than normal across most of Oregon.

This rain system is also helpful because it’s forecast to bring up to an inch of rain east of the Cascades where the drought has persisted.
