Early Sunday, Portland is starting off damp, with light rain in the city and temperatures around 43°F (6°C) at Portland International Airport. The gray skies will not last all day, though. A brief dry stretch with afternoon sunshine is expected, with highs near 52°F, before a cooler and wetter setup moves in on Monday.
Afternoon Sun, Patchy Morning Fog
Pockets of low clouds and patchy fog early on could slow some neighborhood commutes, especially in more sheltered spots, but conditions should improve after sunrise. Most areas will dry out with breaks of sun and light north winds around 3–5 mph. If you need to run errands or get outdoor chores done, this afternoon is your best bet before the next system arrives.
Rain Monday And A Colder, Showery Week
Rain is likely on Monday, February 16, with highs near 46°F and steadier showers continuing into Monday night. A deep trough early next week will pull colder air over the region, dropping snow levels to roughly 500–1,500 feet and setting up a showery pattern through midweek. Forecasters estimate about a 10% chance that a more organized band of precipitation Wednesday night into Thursday (Feb. 18–19) could bring an inch or two of accumulating snow to a few lowland valleys. According to the National Weather Service Portland, advisory-level snow is most likely in the Cascades, while any valley snow would be brief and melt quickly.
Coast And Marine Hazards
The roughest weather story this weekend is along the coast. Small Craft Advisories remain in effect across parts of the coastal waters, and forecasters warn of a high sneaker-wave threat through Sunday evening. Seas were near 9–11 feet early Sunday and are expected to build again Monday night into Tuesday to around 13–15 feet. Stay off rocks and jetties, and keep children and pets well back from the surf.

Plan Ahead
Plan for extra time on Monday commutes and check mountain-pass conditions before heading east, since chain requirements or temporary closures are possible. Mariners and beachgoers should follow posted advisories and check the latest National Weather Service updates before heading out.
