Area Forecast Discussion National Weather Service Seattle WA 826 PM PDT Sun May 12 2024

SYNOPSIS
Upper level ridge will continue to exit to the east today. A weak upper level trough moves through on Monday. Another upper level ridge will build in from the west on Tuesday and remain in place through the remainder of the week. An upper level trough may develop and move through late week into the weekend.

SHORT TERM /TONIGHT THROUGH THURSDAY/
Cloud coverage will continue to increase tonight as a weak shortwave impulse passes over western Washington into tomorrow. This, along with surface high pressure over the eastern Pacific pushing closer to the coast will allow for a westerly push of the marine layer on Monday along the coast and develop mostly cloudy conditions through the interior. A few light showers are possible in the Cascades and foothills as well as the potential for a convergence zone over Snohomish/northern King County. High temperatures will be again be around 10 degrees cooler than today, into the upper 50s to 60s, a few degrees below normal for most.

Surface high pressure broadens on Tuesday and into Wednesday as an upper level ridge develops and approaches the region from the west. High temperatures will bounce back into the 70s with dry conditions and mostly clear skies, with the exception of the marine layer along the coast.

LONG TERM /FRIDAY THROUGH MONDAY/
Model guidance is still somewhat dissonant with a 10 to 15 degree range in high temperatures between the 25th and 75th percentile Thursday and beyond but the synoptic pattern is beginning to look more consistent for the long term forecast. Expecting mostly dry conditions on Thursday. An upper level trough will move through British Columbia and into southern Alberta, and some ensemble members are hinting that the associated surface frontal system may produce some showers in the Cascades on Thursday and into Friday.
Elsewhere, conditions will be mostly dry. Another upper-level trough may approach the region next weekend, but deterministic models disagree on the exact evolution and many ensemble members keep conditions dry through the weekend.

AVIATION
Westerly flow aloft will back to southwesterly tonight as an upper ridge gives way to a weak upper trough and associated front that will cross the region late tonight into early Monday. Increasing onshore low-level flow will bring a push of IFR to low MVFR stratus to the coast this evening. Meanwhile, expect ceilings to gradually lower into the MVFR range early Monday morning with gradual lifting to VFR possible later in the day.

KSEA...VFR with increasing high level moisture and cloud cover expected through the evening. Ceilings expected to fall to the low end of MVFR by 12Z-15Z Monday. Increasing N/NE surface winds to 10-13 kt as a weak shortwave approaches. Confidence on wind direction becomes lower after 09z, with the most likely scenario being a return to southerly winds. However, if the onshore push through the Strait of Juan de Fuca is stronger, this could create a more variable wind direction or delay this switch.

MARINE
Onshore flow continues as a weak system approaches the area across the north. Elevated winds through the Strait of Juan de Fuca through the early morning Monday. The gale warning remains in effect, with small craft advisories for the adjacent waters.
Another round of gusty winds is possible Monday night as well with the following disturbance so will see how winds develop with this round and consider any needed extensions or subsequent warnings or advisories.

Meanwhile, seas remain rather steep across the coastal waters this after noon. This, coupled with continued gusts into the 20-25 kt range, warrants the continued advisory through this evening. Expect that the winds over the coastal waters will ease and the dominant period to lengthen a bit, so this advisory will run through 11 PM as planned for now.

Onshore winds look to temporarily weaken around midweek, but again likely strengthen later in the week. Seas over the coastal waters will build a bit with each passing system to 7 to 9 feet with periods remaining short (around 8 seconds).
