Portland is spending Thursday, May 14, under a cool gray blanket, with temperatures hovering near 54°F at Portland International Airport and mostly cloudy skies expected through the afternoon. Highs should reach about 67°F before slipping back into the mid-60s later in the day. There is only a slight chance of showers after 5 p.m., so most evening plans and the commute should stay largely dry.
Tonight And Friday
Skies stay mostly cloudy Thursday night, May 14, with a low around 48°F. Friday, May 15, comes in a bit cooler, with a high near 63°F. West-southwest winds will be on the light to moderate side, generally 3–13 mph, with gusts potentially reaching into the low 20s by Friday evening. If you have outdoor plans Friday night, it is smart to keep a light rain layer within reach.
Late Friday Into Saturday
A stronger system moves in late Friday, May 15, into Saturday, May 16, bringing the best chances for steady showers and scattered afternoon thunderstorms on Saturday. Showers will be most numerous near the coast and across the north metro area, and a few spots could pick up a few tenths of an inch of rain in brief, heavier bursts. Gusty west winds around 20–25 mph are possible. Snow levels may drop to roughly 3,500–4,500 feet late Friday into Saturday, and Small Craft Advisories are expected for portions of the outer coastal waters and the Columbia River Bar, so boaters should plan accordingly, according to the National Weather Service Portland.
What This Means For Your Plans
Count on a mostly dry Thursday afternoon, but prepare for a wetter, breezier stretch late Friday into Saturday if you have events or errands lined up. Roads may be slick at times, and gusts can be a nuisance for cyclists and high-profile vehicles. Transit riders should check for any service changes before heading out and build in a little extra time; see TriMet service alerts for updates. If you are aiming for a coastal escape or planning to take a boat out, consider postponing nonessential trips during the advisory period or taking extra precautions.
Sunday And Early Next Week
Conditions should dry out by Sunday, May 17, with partly sunny skies and highs near 65°F. Early next week looks milder and a bit more cooperative for outdoor plans, with inland highs climbing into the upper 60s to low 70s after Saturday’s unsettled stretch.
