(Portland, Oregon) – Expect more snow for the Oregon Coast Range in the coming weekend, but possibly some dustings later in the week making for some travel impact. Meanwhile, Portland, the Willamette Valley and surrounding regions will still get bits of the white stuff at higher elevations, then turning to a drier and colder week.

The National Weather Service (NWS) said there's some sunny days ahead for the coastline, Coast Range and the valley, but that will only make things colder, given that a lack of clouds lets all the heat flow upwards. However, you'll still need to take caution over the weekend.

“Skies will become cloudier Friday night into Saturday with showers increasing from west to east as a weak surface low moves inland,” the NWS said. “This low will bring accumulating snow in the Coast Range and Cascades, however forecast snow amounts are not high enough to justify the issuance of a winter weather advisory. Nevertheless, there will be minor travel impacts over the coastal mountains with 1-2 inches along portions of highway 26 and a dusting to one inch along the highest portions of highway 22.”

On the Oregon coast and south Washington coast look for rain, but that precipitation will create a rain / snow mix in the valley and I-5 corridor, including Portland/Vancouver metro, lower Columbia and Cowlitz Valley.

Saturday still sees some rain and snow in elevations above 1200 feet but the snow levels soon rocket upwards, leaving the mountains with mere droplets. Sunday there's more chances of rain, while the midweek stays generally chilly but dry or just above freezing.

“Any snow that does fall below 500 feet will most likely melt upon contact with the ground due to southerly winds and slightly above freezing surface temps,” the NWS said. A very light dusting on elevated surfaces and grassy surfaces will be possible at best, and no travel impacts are expected for elevations below 500 feet.”

The NWS said it's possible there will be up to half an inch in areas like Portland's West Hils or Chehalem mountains, as well as Salem's Eola Hills.

“Overall, another day with flakes in the air down to the valley floor, but no accumulation to worry about,” the NWS said.

Along the coastline, sunny days midweek are a bit balmy compared to the valley: clocking in at near 50 degrees in many areas like Seaside, Lincoln City or Coos Bay.

As the week rolls on, the metro area gets chillier. East winds from the Gorge will take over and drive temps down through Thursday.

“The long term forecast is highlighted by high confidence for abnormally cold temperatures and low confidence for potential snow, sleet and/or freezing rain down to the valley floor,” the NWS said.
