Synopsis for the northern and central washington coastal and inland waters - Broad surface ridging will remain centered well offshore with low pressure inland and will result in onshore flow for much of the forecast period.

Area Forecast Discussion National Weather Service Seattle WA 821 PM PDT Fri May 17 2024

SYNOPSIS
Upper level troughing will be the main feature over western Washington this weekend, keeping showery and cooler conditions around. A weak ridge looks to briefly build in the area for the start of next week, before troughing returns for more cool and showery conditions.

UPDATE
Evening remains dry and a mix of clouds and sun continue through the evening. Updated aviation section below, otherwise forecast remains on track.

HPR

SHORT TERM /TONIGHT THROUGH MONDAY/
Upper-level trough is east of the Cascades as its axis is over the Inland Northwest. Upstream, a transient ridge is taking aim at western Washington as it's currently overhead Vancouver Island. As a result, we'll see mostly dry conditions across the area this evening. Can't rule out spotty light showers for higher elevations tonight. Otherwise, benign weather is in the forecast. Overnight lows are to fall into the low to mid 40s.

Widespread precipitation looks to return on Saturday. The next upper-low is slated to arrive with rain showers and below normal high temperatures in the mid 50s to near 60 F. A few showers are to remain on Sunday, mostly over the mountains before conditions dry out overnight as upper-level ridging builds overhead. This will set up a dry day on Monday as deterministic models indicates the aforementioned ridge axis nosing into BC and far western Alberta. We'll also see the warmest temperatures of the upcoming week on Monday with highs in the mid 60s to near 70 F, around average for mid-late May. But, rain and cooler temperatures will soon return as the week continues. Overnight lows are to remain in the 40s through the short term forecast.

LONG TERM /TUESDAY THROUGH FRIDAY/
As hinted, we'll be back to regularly scheduled programming starting on Tuesday. Active weather looks to resume as another upper-low out of BC dives south into the region followed by an additional shortwave sliding through on Wednesday. Showery and cool weather will continue into the long term period with temperatures slightly below normal.

AVIATION
West to northwest flow continues into Saturday with an upper trough over the Pacific Northwest. Generally VFR mid to high clouds this evening with onshore flow at the surface. Another trough will move through on Saturday for lowering cigs into Saturday morning. Generally MVFR Saturday morning with some areas remaining low end VFR. In addition, light rain increases Saturday morning and continues into the afternoon, especially over central Puget Sound with convergence activity. MVFR cigs will slowly improve to VFR, generally 3000-5000 ft Saturday afternoon before some SCT/BKN later Saturday. Rain showers dissipate later Saturday. Localized IFR cannot be ruled out either Saturday morning, but expected to be isolated. Light S/SW west tonight with increasing onshore flow on Saturday.

KSEA...VFR conditions continue through early tonight. Cigs will begin to lower tonight into Saturday morning with low level moisture and a system moving towards the area. MVFR cigs expected to develop late tonight into Saturday morning, with slow improvement to VFR Saturday afternoon. Rain potential increases Saturday afternoon before dissipating in the evening. Southerly winds continue into Saturday morning before shifting north Saturday afternoon. Although north winds are expected to remain generally below 7kt on Saturday, there may be brief periods of N winds 7-10 kts. JD

MARINE
High pressure over the NE Pacific will interact with lower pressure inland and will maintain onshore flow across the region through the weekend. Strongest winds will likely be along the Strait of Juan de Fuca with Small Craft Advisory winds looking to persist through late tonight. The next frontal system then looks to move across the area waters on Tuesday.

Seas hovering at 7-9 ft across the coastal waters this afternoon.
Expect seas to continue to subside towards 5-7 ft over the weekend and to persist into early next week. 14
