Portland is in for a stunning late-May Thursday — sunny skies with a high near 86°F — but a thunderstorm threat moves in after 7 PM tonight, so make the most of the afternoon.

Today’s Setup

A weak ridge of high pressure is keeping the metro warm this morning, with temperatures climbing toward 86°F under mostly clear skies and light northwest winds of 1 to 8 mph. The National Weather Service notes that organized convection will build this afternoon primarily over the Cascades and Hood River Valley. There’s a real — if lower — chance storms drift west into the Portland/Vancouver metro by evening. The Weather Prediction Center has also flagged a marginal risk of excessive rainfall for portions of the Northwest today through Friday morning, mostly a timing concern for those evening hours.

Best Window To Be Outside

Sunrise through roughly 3–4 PM PT is your golden window. This is prime time for Forest Park trails, a Willamette River float, or a backyard cookout on your propane gas grill. If you want some sun protection for the afternoon, check out UPF 50+ fishing shirts for $6.50 — a solid deal for days exactly like today.

Allergy Heads-Up

Warm, breezy mornings push pollen counts higher across the Willamette Valley, and today is no exception. Keep an allergy relief nasal spray in your bag if you’re spending extended time outside, and run a HEPA air purifier at home to keep indoor air clean when you return.

Storm Risk Tonight

Showers and thunderstorms are possible after 7 PM PT, with WNW winds gusting to 20 mph and a low settling near 54°F. Tuck a packable rain jacket in your bag if you’re heading out for the evening — the National Weather Service puts the storm window roughly between 7 PM and midnight, with drier conditions returning overnight.

Weekend Events & What To Expect

Friday (May 29) brings the Oregon Ducks Baseball team hosting the NCAA Baseball Regional at PK Park. Morning showers are possible before 8 AM with a high near 66°F and gusts to 20 mph — bring a layer and rain gear for early innings.

Saturday (May 30) looks considerably drier. Sierra Ferrell takes the outdoor stage at McMenamins Historic Edgefield Manor — a great venue when the skies cooperate. Grab a Sierra Ferrell t-shirt and Find tickets on StubHub if you’re still hunting for seats. Also Saturday, the Portland Fire host the Indiana Fever at Moda Center — fully indoors, so weather is zero factor. Grab Official team gear on Fanatics before tip-off.

Dinner Tonight & Next Few Days

Tonight’s warm-then-stormy setup is perfect for a quick pasta or stir-fry you can pull together before the thunder rolls in. Need ingredients? You can order groceries on Amazon and have everything delivered well before the evening weather turns.

Looking ahead: a cooler, mostly cloudy Friday (high near 66°F) gives way to a drier weekend and an early-next-week warm-up, per the National Weather Service. Browse outdoor gear deals to stay ready for whatever Portland spring decides to throw at you.
