The Portland area is expected to receive up to half a foot of snow in between Friday night and Saturday, with the potential for more accumulation later into the weekend. 

“We’re expecting accumulations on the order of 2 to 6 inches in the Portland metro area including Clark County in southwest Washington,” said Andy Bryant with the National Weather Service’s Portland office. 

In Salem and Eugene, amounts of one to four inches can be expected. Some areas on the coast may also see snow, Bryant said. The Coast Range and Cascades are also expected to see “several inches” of snow, he said.

Accumulating snow will arrive anywhere from Friday into early Saturday depending on location.

“We’ll see some rain [Friday] afternoon and evening in much of the area,” Bryant said. “Overnight we’re expecting colder air to move in and that rain will change to snow and that could happen in the Portland metro area as early as somewhere between 7 and 10 p.m.”

He added: “The farther north you are, the earlier that [accumulating snow] is probably going to be.”

Farther south into the Willamette Valley, that change from rain to snow is expected to happen later Friday night or earlier into Saturday morning. 

“And it just keeps coming,” Bryant said. “We get a little bit of a break on Sunday, and then there’s the potential for more snow Sunday night and Monday — details still to be determined.”
