Snow Accumulation for Portland, Oregon Coast Range; Few Flakes on Beaches

(Portland, Oregon) – The Oregon coast may actually see a tiny bit of snow this week, but it won’t last long and it won’t stick. A cold front is moving into northwest Oregon and southwest Washington and you’re going to start seeing a few dustings and some sticking snow, depending where you are. All that is further inland, however.

According to the National Weather Service (NWS), parts of Portland will likely see snow, though usually mixed with rain, while its upper elevations may see some accumulation. It’s the Oregon Coast Range you may have to worry about during some parts of the early week, however.

“The coldest air mass of the season is expected to move over the Pacific Northwest Sunday night and linger through most of the upcoming week,” the NWS said. “Snow levels will lower through the day Sunday, likely falling below 1000’ by Sunday night. Low pressure is expected to set up just offshore Sunday night and Monday bringing light precipitation to the region.”

It’s the Oregon Coast Range that will get the worst of this, affecting traffic on Highway 18, Highway 6 and Highway 26. Routes south of these will fare better.

“Precipitation will likely fall as snow for much of the Coast Range, Willapa Hills, and Cascade foothills bringing the first accumulating snowfall of the winter to these areas,” the NWS said. “This is a complex low weather pattern and honing in on the timing and strength of the features is challenging. Good news is that the road surface temperatures for the lower valley locations will be likely be too warm to support accumulating snow.”

One to three inches of accumulation is expected in the Lincoln County portion of the coast range, while northern portions may see as much as four inches of snow gathering.

For those higher elevations as well as Portland, most of the snowfall will be brief and often mixed with rain. But there is the possibility of some roadway issues in that area as well as the coast range.

“Road conditions Sunday night into Monday may be more problematic as any liquid remaining on the road surfaces may freeze and result in icy spots,” the NWS said.

For the beaches, however, there is only a slight chance for seeing even just a few flakes. Chance for precipitation is 90 percent, the NWS said, but little to no snow accumulation is expected.

There is a chance of another snow event later in the week, however. - See Oregon Coast Traffic Conditions. - See Oregon Coast Weather. More photos of Oregon snow scenes below:
