Tuesday, April 28, 2026 — Seattle woke up to a classic gray special this morning, with light rain, drizzle and patchy fog hanging over the city and temperatures near 48°F at Boeing Field. Visibility is reduced in spots and wet roads could slow commutes during the morning peak. The damp start is expected to stay mostly on the light side, more mist and brief showers than any kind of steady soaker, with conditions set to trend drier and brighter later in the week.
Forecast Through Early Next Week
Mostly cloudy skies stick around Tuesday, with a high near 59°F before a building area of high pressure starts to tip the balance toward clearer weather. Wednesday is on track to be sunny and mild with a high near 65°F, and Thursday looks mostly sunny with highs around 70°F before a dry front slides in late in the day.
From there, temperatures are projected to climb into the mid 70s by Sunday and near 78°F on Monday, with probabilistic guidance showing about a 20–30% chance of a moderate heat risk for the Seattle–Tacoma metro area. The National Weather Service also notes that no river flooding is expected over the next seven days.
Commute and Marine Notes
Low clouds and stratus are set to keep visibility hit-or-miss through Tuesday morning, with fog expected to lift and low ceilings to scatter into the afternoon, improving conditions for evening travel. KSEA and other regional airports may see brief pockets of MVFR this morning, but ceilings are expected to lift by Wednesday.
Out on the water, mariners can look for light onshore flow through midweek, with a stronger onshore push possible down the Strait of Juan de Fuca late Thursday into Friday. Boats and ferry riders are advised to check updated marine forecasts before heading out.
