Area Forecast Discussion National Weather Service Seattle WA 854 PM PDT Sat May 4 2024

SYNOPSIS
Cool and unsettled weather will continue over western Washington into early next week. A pattern shift can be expected by midweek as upper level ridging builds over our region, bringing drier and a much warmer conditions to our area.

SHORT TERM /TONIGHT THROUGH TUESDAY/
Cutoff upper low and attendant surface low continue to slowly move across Oregon and parts of the Great Basin this evening. Precipitation coverage has dwindled to some extent on radar, though light drizzle, mist, and otherwise damp conditions persist across most of western Washington. Much of the remaining rain into tonight will be focused along the coast, the Olympic Peninsula, and Olympia southward as thats where the boundary is focused. Low temperatures tonight won't drop a whole lot with mid to low 40s across the region.

The broad area of low pressure associated with an upper level trough will continue to move eastward inland on Sunday, but will still remain close enough to continue showers for western Washington. With another trough right behind it, onshore flow will be strong Sunday providing more wetter conditions, especially for interior locations. Along with rain showers throughout the interior, some snow can be expected in the higher Cascades..
generally around 4000 to 5000 feet, but will be rather light.

As the upper level trough crosses the region into Monday, cooler air aloft will help produce some instability along with steep lapse rates, which could help the development of some isolated thunderstorms over the interior into Monday afternoon. Strong onshore flow will continue as well, also prompting the development of a potential Puget Sound Convergence zone into Monday evening.

Unsettled showery conditions look to continue through Tuesday and Wednesday as the upper level trough lingers over the region.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
There is strong support from ensemble guidance that a pattern shift is upon western Washington, with an upper level ridge building over the region starting on Wednesday. Although there are some small variations in timing and placement of the upper level ridge, there is a general agreement that much warmer and drier conditions will take place throughout much of the long term, with NBM high temperatures in the lowlands around mid to upper 70s into Friday and Saturday.

AVIATION
An upper low will move into the Oregon-California border this evening with southeasterly flow aloft transitioning westerly on Sunday. Generally VFR north of the Seattle terminals this evening with MVFR/IFR across the coast and southern Puget Sound. CIGs will continue to slowly lower through the night to where most all terminals will be MVFR/IFR by Sunday morning. Light rain will continue at times into early tonight, with another round of lighter rain on Sunday. Some improvement to CIGs possible by Sunday afternoon, especially north of Seattle, but generally MVFR to low- end VFR expected through the TAF period. Southerly winds through the TAF period, increasing overnight to 10 to 15 kt with gusts to 25 kt possible in the afternoon tomorrow.

KSEA...MVFR ceilings this evening. CIGs will remain low-end MVFR with potentially periods of IFR tonight into Sunday morning. CIGs generally remain MVFR Sunday afternoon with light rain at times.
Southerly winds, increasing overnight, becoming gusty by tomorrow afternoon and evening.

JD/LH

MARINE
A frontal system will move through the southern portions of the waters into this evening. Another weather system will move across the waters Sunday night into Monday. Northwesterly winds this evening will transition more west to southwesterly tonight into Sunday. A westerly push through the Central and Eastern Strait of Juan de Fuca tonight will result in brief Small Craft Advisory level wind gusts, for which a Small Craft Advisory is in effect through tomorrow afternoon. West winds then increase through the Strait of Juan de Fuca again Sunday afternoon into early Monday for another round of SCA winds. Winds may also reach SCA for adjacent areas, including Admiralty Inlet and Northern Inland Waters, and south of the San Juan Islands during this period. In addition, winds will increase Sunday afternoon into Monday morning for Puget Sound with an increased likelihood of SCA wind gusts during this period.

Additional westerly pushes through the Strait of Juan de Fuca are likely Monday and Tuesday evening. Winds will then transition more northerly Wednesday into late week as high pressure builds into the area.

Seas of 5 to 8 feet will continue into Monday before building to 9 to 12 feet Monday night through Tuesday.
