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. High pressure well offshore looks to remain into early next week. Another frontal system looks to traverse the area waters on Tuesday.

Area Forecast Discussion National Weather Service Seattle WA 259 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.

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.

.Northwesterly flow will persist aloft today as an upper level trough over WA/ID continues to push east and a ridge of high pressure remains situated over the NE Pacific. Flow aloft will become more westerly into Saturday as another trough drops down into WA from BC. Post- frontal onshore flow will continue tonight into Saturday. Radar this afternoon shows some light showers in the north and central Cascades, but shows showers gradually diminishing. Conditions widespread VFR this afternoon and expect conditions to remain so through tonight. With the low level air mass remaining moist, and with onshore flow continuing, expect to see another round of MVFR cigs develop overnight into Saturday morning. An approaching shortwave will bring another round of showers to the area on Saturday and could result in localized MVFR to IFR conditions at times across area terminals.

KSEA...VFR conditions to persist through tonight. With low level moisture, could see another round of MVFR conditions develop early Saturday. Winds generally S/SW persisting at 8 to 12 kt, with a few gusts to 20 kt. Winds look to ease towards 5 to 10 kt overnight and then shift to the N, but persist at 7 kt or less Saturday afternoon into evening. Showers will possible at times on Saturday. 14

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
