Area Forecast Discussion National Weather Service Seattle WA 329 PM PDT Sat May 18 2024

SYNOPSIS
Cool and showery conditions will persist today with an upper level trough situated over the region. The trough will move east by Sunday afternoon allowing for upper level ridging to nudge into Western Washington. Dry and warmer conditions are expected Monday, before another system moves into the region on Tuesday for a return to wet and unsettled conditions. Troughing over the region then looks to bring unsettled conditions through much of the next week.

SHORT TERM /TONIGHT THROUGH TUESDAY/
An upper level trough sinking into the area from British Columbia today will continue to bring cooler and showery weather to western Washington. Radar this afternoon shows scattered shower activity across much of western Washington. Breaks in the cloud cover and increasing instability will yield a slight chance of thunder for the area through this evening. Thunder chances then wane through the evening hours. Expect shower activity to continue through this evening and gradually taper through the overnight period into Sunday. High temperatures today will generally trend a good 5 to 10 degrees below normal - topping out in the mid to upper 50s.

The upper trough axis will then shift east tonight, allowing for showers to gradually taper on Sunday. Hi-res guidance indicates only a few remnant showers persisting in the Cascades. Drier northerly flow aloft Sunday afternoon will allow bring some afternoon sun to western Washington. High temperatures on Sunday will warm a few degrees and generally look to top out in the upper 50s to low 60s.

Weak upper ridging will nudge into the region on Monday for drier and warmer conditions. Afternoon highs look to climb into the mid to upper 60s for the interior. Highs along the coast will remain in the upper 50s and low 60s.

The next upper level trough then looks to dig southward from British Columbia and into western WA through the day on Tuesday.
Its associated surface front will move across the region, bringing the next round of more widespread precipitation to western WA.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Cool and showery conditions will persist into midweek as the aforementioned upper trough continues to traverse southeastward across the Pacific Northwest.
The forecast details become a bit more uncertain late in the week, though ensembles generally hint at troughing over the Pacific Northwest persisting while a ridge of high pressure remains situated over the Gulf of Alaska. Ensembles still struggling with the depth of the trough over the Western US. However, with guidance continuing to hint at troughing, have maintained cooler conditions and chances of showers in the forecast for now through late week.

AVIATION
West/northwesterly flow aloft today as an upper level trough moves through the region. Ceilings this afternoon bouncing between VFR and MVFR with a broken cloud deck and scattered showers across the region. Scattered showers will begin to diminish the evening. Ceilings will remain through the early evening, with a decent chance of more solidly MVFR conditions building in between around 12-18Z Sunday. Cloud cover will break throughout the day tomorrow with a return to VFR conditions.

Onshore winds continue through the TAF period, decreasing to light overnight. Northerly through the Seattle area, southerly through the remainder of the interior, then transitioning back to south through the entire interior tonight.

KSEA...Ceilings between VFR and MVFR with light showers in the vicinity. Showers diminishing by around 03Z. Better chance at redeveloping MVFR CIGs between 12-18Z Sunday. Winds generally light northerly this afternoon and evening, switching back to southerly between 03-06Z Sunday. Winds remain light southerly through the overnight and into tomorrow.

LH

MARINE
Broad high pressure over the NE Pacific will maintain onshore flow across western WA through the weekend. Strongest winds will be over the Strait of Juan de Fuca with Small Craft Advisory winds extending through late tonight. The next frontal system looks to move through the area on Tuesday, with another push of westerlies down the strait possible with the potential for additional headlines. Otherwise, winds look to remain fairly benign through the coastal waters.

Seas around 6 ft through most of the forecast period, through the frontal system on Tuesday may raise seas closer to 8 to 10 ft, making waves steep with an 8 second period.
