Area Forecast Discussion National Weather Service Seattle WA 730 PM PDT Wed Apr 23 2025
SYNOPSIS
High pressure will build over the region through Thursday, with dry and warming conditions. Cooler and wetter weather will move in later this weekend, with a return of drier and warmer weather possible towards the latter half of next week.
SHORT TERM /TONIGHT THROUGH SATURDAY/
Another evening under the ridge with clear skies in place over W WA. Some low 60s still in place over the south Sound and SW interior at the time of this writing, while remaining obs find themselves in the mid to upper 50s. Inherited forecast remains on track with no need for evening updates. For additional forecast details, please refer to the Previous Discussion section below.

From Previous Discussion...Upper level ridging will continue to build over the region through Thursday for dry and warm conditions.
Temperatures this afternoon have been warming steadily into the mid to upper 60s, with some localized spots in 70s. Temperatures will warm a touch more on Thursday, with most of the interior locations seeing temperatures in the lower 70s - areas along the water will see highs close to the mid 60s.
A weak trough offshore will start to increase cloud cover slightly heading into Friday, as a cutoff low continues to move southward into California. Latest ensemble guidance has continued this track of a southward progression, which would decrease precipitation chances for western Washington. High temperatures on Friday will continue to be the upper 60s/lower 70s.
A split flow regime looks to set up heading into the weekend, with Saturday looking to be mainly dry and temperatures in the low to mid 60s.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Split flow will slightly differ as a upper trough opens way for precipitation chances on Sunday. Ensembles are having a difficult time grasping on the strength and spread of precipitation as it seems weak, but overall, it looks generally light, if any precip, on Sunday.
Showers may linger through midweek before drier weather returns.
Mazurkiewicz
AVIATION
An upper level ridge axis over the coastal waters will shift onshore tonight with north to northwest flow aloft becoming light southerly overnight. The low level flow remains northerly. The air mass is dry and stable. Mostly clear skies expected through the period except for some patchy stratus along the coast and locally in the Chehalis Gap on Thursday morning.
KSEA...VFR. Surface winds north/northwesterly 5 to 8 knots becoming light northeasterly tonight then north/northwesterly 7 to 10 knots once again Thursday afternoon. 27
MARINE
A surface ridge centered offshore will weaken through tomorrow. A broad area of weak surface low pressure will develop late in the week over the Pacific Northwest while high pressure remains centered well offshore. This will lead to an overall increase in onshore flow leading into the upcoming weekend. The end result will likely be a period of small craft advisory winds across the coastal waters as well as the central/east portions of the strait. 27
HYDROLOGY
No river flooding is expected over the next 7 days.
SEW WATCHES/WARNINGS/ADVISORIES
WA...None.
