Area Forecast Discussion National Weather Service Seattle WA 841 AM PDT Sat May 4 2024

UPDATE
Light rain continues at times this morning, primarily from Snohomish County southward and along the Olympic Peninsula with an upper low tracking into southern Oregon and northern California. This trend will continue today, with the steadiest precipitation along the coast and south of Seattle. Otherwise, temperatures today in the 50s, with the exception of Whatcom County into the 60s.

SYNOPSIS
A return to cool and unsettled conditions will continue across the Pacific Northwest this weekend, with little change through early next week. A shift in the pattern is then expected for the second half of next week as high pressure aloft likely develops over the region. This will bring a return of drier and much warmer conditions to the region.

SHORT TERM /TODAY THROUGH MONDAY/
Latest NWS radar imagery reveals the steady precipitation has largely remained draped along and south of a roughly Port Angeles to Mount Rainier line early this morning. With the boundary making little significant progress, still expect the progression of any rain north of Seattle to be rather minimal through the morning today. Some light rain likely expands inland and a little more north, but the focus for the consistent precipitation will remain across the southwestern portions of the local area. In fact areas of Whatcom County near the border will likely remain mostly dry and also a bit on the warmer side. The upper level trough slides east of the region by early Sunday but remains close enough to continue to spread some showers across the local area. More significantly, the next cold upper trough induces stronger onshore flow as it approaches, which will increase the rain coverage across the region. With stronger orographic support, expect heavier rainfall up in the mountains (and snow in the higher Cascades above 4000 ft or so) but some shadowing to keep rainfall totals in the Seattle metro area notably lower. We stay locked in the active pattern with the upper trough crossing the region into Monday. As lapse rates steepen, will have the potential for some isolated thunderstorms and stronger onshore flow will likely bring a developing Puget Sound Convergence Zone.

LONG TERM /TUESDAY THROUGH FRIDAY/
The start of the long term period likely remains unsettled and showery with the lingering upper trough still over the region. Strong support in the ensemble guidance for a pattern shift around midweek though, with high confidence in an upper ridge taking shape over or near the region.
While still some subtle variations among the various clusters of solutions, the general trend suggests this warmer and drier weather will be with us for the second half of the week. Have maintained temperatures in line with the NBM, with likely temperatures in the mid to upper 70s across much of the lowlands late in the week.

AVIATION
A frontal system will move over the southern portion of the area today with an associated upper low moving into the Oregon/California region this evening for southerly flow aloft becoming more southeasterly tonight. Generally VFR mid and high clouds this morning with areas of MVFR/IFR and even patchy LIFR cigs into portions of southern Puget Sound. Lower cigs, generally MVFR/IFR will expand northward later this afternoon and into this evening, with MVFR/IFR cigs tonight into Sunday morning. In addition, light rain will continue at times, generally KPAE southward and along the Olympic Peninsula. A more northerly component exists to this winds this morning, before winds for most areas transitions to W/SW later this afternoon.

KSEA...VFR mid clouds with light rain at times through this morning. Cigs will slowly lower to MVFR this afternoon and especially this evening. Brief periods of IFR may occur tonight into Sunday morning. North winds ranging 9 to 14 kts this morning will transition to SW later this afternoon (generally between 21-00z). Southerly winds expected tonight. JD
