Seattle is starting Thursday with wall-to-wall sunshine and a high near 78°F — one of the best days this month to get outside. Take full advantage today, because rain arrives tonight and will dominate your Friday. Check the Seattle weather forecast for updates as conditions shift.
Today’s Setup
The National Weather Service puts Western Washington in a brief sweet spot between a weakening upper-level low over California and a trough exiting the Gulf of Alaska. Warm air aloft — 850 mb temps near plus 15°C — means sunshine from Ballard to Bellevue, with light northwest winds at 0 to 6 mph. Green Lake, Discovery Park, and the Cougar Mountain trails are all excellent choices. Evening lows drop to the low 50s, so bring a layer if you’re out after sunset.
One catch: warm, clear days drive pollen counts higher across the metro. Tuck an allergy relief nasal spray in your bag before heading out, and consider running a HEPA air purifier at home tonight if you’ve had the windows open all day.
Rain, Wind & Flood Risk
Light rain arrives after 11 PM Thursday, pushed in by a marine surge through the Strait of Juan de Fuca. By Friday morning, the National Weather Service puts the chance of rain at 70% with a high near 59°F. The Weather Prediction Center flags a marginal risk of excessive rainfall across portions of the Northwest on Friday — totals should stay light (under a tenth of an inch), but a packable rain jacket is a must for the next 48 hours.
Mariners Gameday Weather: Friday vs. Arizona
The Seattle Mariners host the Arizona Diamondbacks at T-Mobile Park on Friday, May 29 — right in the wet window. Expect clouds, temperatures near 59°F, and a solid chance of drizzle during game time. Layer up: a Seattle Mariners jersey over a long sleeve with a Seattle Mariners fitted cap handles the chill nicely. Snag seats via Find tickets on StubHub or Get tickets on SeatGeek.
Tonight’s Events & Weekend Plans
Tonight is a great night out before the rain flips things. Joe Jackson + Band brings the Hope and Fury Tour 2026 to Moore Theatre — fully indoors and weather-proof. Heading to the Black Keys: PEACHES ‘N KREAM at Remlinger Farms on Friday? That’s an outdoor venue smack in the middle of the rain window — waterproof hiking boots and a rain shell are the smart call. Browse outdoor gear deals before you head out.
Dinner Tonight
A sunny 78°F evening is perfect for pasta primavera or a fresh veggie stir-fry. Need tonight’s ingredients? Amazon Fresh groceries can be at your door in hours — you can order groceries on Amazon right from your phone.
Next Few Days
Friday stays cloudy and wet with a high near 59°F. Saturday continues with onshore flow and lingering showers. Sunday into early next week, the National Weather Service hints at an upper-level ridge building, with drier and warmer conditions possible as we head into June — a welcome turn after the soggy stretch.
