Seattle (Evening Washington News) May 19, 2026 Seattle weather remains mostly cloudy on Tuesday, with cooler conditions, light drizzle possible at times, and a gradual shift towards warmer, sunnier weather later in the week, according to a report from Fox 13 Seattle on Tuesday, January 8, 2025. As reported by the Fox 13 Seattle weather desk, western Washington will begin the day under onshore flow, with clouds expected to stay in place and any rain remaining light.
What is the weather outlook for Tuesday in Seattle?
Cloudy skies are expected to dominate much of Tuesday, with possible drizzle to start the day and only light rainfall if any develops.
The forecast suggests that the region will stay cooler because of onshore flow, which is bringing marine air inland and limiting sunshine.
As reported by Fox 13 Seattle, the main weather pattern on Tuesday is not a heavy rain event but a modestly damp and overcast one.
The source says clouds will linger through the day, which means Seattle residents should expect a grey, cool day rather than a bright or warm one.
Why is western Washington staying cooler?
The cooler conditions are being driven by onshore flow, which typically brings air in from the Pacific and over the coast.
In this case, that pattern is helping maintain cloud cover and limiting daytime heating across western Washington.
In practical terms, this keeps temperatures suppressed in the Seattle area, where highs are forecast to remain in the mid 60s.
The weather desk’s outlook shows that Tuesday will be noticeably cooler than the warmer stretch expected later in the week.
When does warmer weather return?
Warmer and sunnier conditions are expected to return on Wednesday. The forecast then points to a longer period of improved weather lasting through most of Memorial Day weekend.
Temperatures are expected to rise into the 70s before there is a slight chance of showers late Sunday into Monday.
That suggests a fairly favourable stretch for outdoor plans, especially after the damp start to the week.
What does this mean for Memorial Day weekend plans?
The forecast points to a mostly improved holiday period, with sunshine and warmer temperatures taking hold after Wednesday.
That should offer better conditions for travel, outdoor gatherings, and activities across western Washington.
However, the slight chance of showers late Sunday into Monday means the weekend may not stay completely dry through its end. People planning events should keep an eye on later updates in case the weather pattern shifts.
What was reported by Fox 13 Seattle?
Fox 13 Seattle reported that Tuesday would begin with mostly cloudy skies, onshore flow and possible drizzle.
The station also said clouds would persist through the day and any rainfall would be light.
The same report added that sunnier and warmer weather is set to return Wednesday and continue for most of the holiday weekend.
It also said temperatures could reach the 70s before a slight chance of showers late Sunday into Monday.
Background of this development
Seattle’s weather often shifts quickly when onshore flow develops, especially in spring. That pattern can push in cooler, moisture-laden air from the coast, creating cloud cover, drizzle and lower daytime temperatures.
The current forecast fits that broader seasonal pattern, with a temporary cool, cloudy spell before a more settled and warmer period arrives later in the week.
For western Washington, this is a common transition in late spring when marine influence remains strong early in the week.
Prediction for local audiences
For Seattle residents, the immediate effect is a cooler and greyer Tuesday that may affect commuting, outdoor work and short-term plans. Light drizzle and low clouds can make conditions feel more subdued than the calendar suggests.
For people planning Memorial Day weekend activities, the later outlook is more encouraging because temperatures are expected to improve into the 70s. The only potential disruption in the forecast is the slight chance of showers late Sunday into Monday, which could matter for beach trips, park visits and holiday travel.
