National Weather Service Portland (NWS) issued a “special weather statement” Wednesday concerning a pair of cold fronts bringing frigid temperatures this weekend through early next week, but confidence is low for snow on the coast.

“Cold air is coming,” NWS Meteorologist Rebecca Muessle said Thursday. “Westerly winds will keep the coast temperatures moderate so we don’t have a lot of confidence for snow in coastal areas. We are expecting snow levels for the coast to be around 1,000 feet.”

Cold fronts will likely bring snow to the Cascades this weekend and snow levels are expected to remain well above the valley floor through Sunday, NWS officials said.

Colder air is expected to arrive early next week, and with it, a chance for snow for most of the Pacific Northwest and southwest Washington. An increasing number of NWS forecast models suggest moisture from the Gulf of Alaska will raise the chance for snow down to the lowest elevations.

Muessle said the pair of cold fronts could cause high surf conditions and NWS is looking into issuing alerts for Friday and Saturday for the coast.

“Right now it looks like 20-25 foot waves are possible,” she said. “Stay tuned to National Weather Service for alerts.”
