Area Forecast Discussion National Weather Service Seattle WA 926 AM PDT Tue Apr 23 2024

UPDATE
Forecast on track this morning. Cross cascade gradient has turned negative and reports from North Bend have east winds gusting in the 15 to 25 mph range this morning. Low level flow will not turn onshore for the interior until tonight allowing high temperatures to rise into the mid 60s to lower 70s. Upper level trough arriving Wednesday with cooler and wetter weather into the weekend. Previous discussion below with update aviation and marine sections. Felton

SYNOPSIS
High pressure will maintain mild and dry conditions across the region through Tuesday. From Wednesday through the end of the week, expect a series of disturbances to bring a return of clouds and precipitation with temperatures trending closer to seasonal normals. This pattern will remain through the start of next week with periodic round of mountain snow and lowland rain.

SHORT TERM /TODAY THROUGH THURSDAY/
High pressure brings one more dry and mild day to western WA today. Temperatures will track a few degrees warmer in the interior with afternoon highs in the upper 60s to lower 70s. The coast will see 60s too but winds will be switching to cooler onshore flow this afternoon.

Cooler, cloudier and wetter weather returns for Wednesday as an upper low tracks through B.C. (with a weak front draped over western WA). Most of the rainfall will be over the coast and mountains with some rain shadowing in the central sound. A trough moves inland on Thursday with more rain and cool weather (highs in the 50s). Rainfall will be more widespread with much of the region seeing measurable amounts. 33

LONG TERM /FRIDAY THROUGH MONDAY/
Troughing over the Pac NW will keep western WA cool and showery moving into this weekend.
Temperatures will track below average with highs in the 50s. Lows will be in the 40s. Then, looking further ahead, a deep upper low will spin offshore as we move into next week. Temperatures continue to dip below average and we may see lows in the mid to upper 30s Monday night. Snow levels will lower to around 3000 ft with a few inches of snow possible at the mountain highway passes.

AVIATION
SW winds aloft as an upper-ridge axis shifts eastward with troughing upstream. Widespread VFR conditions are expected through much of the upcoming TAF period. High clouds are pushing in ahead of the next disturbance entering later on Wednesday.
Surface winds are on the lighter side or calm for many this morning but should begin to pick up in the afternoon out of the W/NW between 5- 10 kt as winds push through the Strait of Juan de Fuca and into the Puget Sound area. Winds will trend more out of the south on later overnight in response to the aforementioned system.

KSEA
VFR throughout the TAF period with high clouds. NNE winds 4 to 8 kt this morning becoming WNW 5 to 10 kt in the afternoon before a transition to southerly after around 12Z tomorrow morning.

McMillian/LH

MARINE
Thermal trough to our south with surface high pressure well offshore. Generally benign seas today aside from the Central and Eastern Strait of Juan de Fuca where a SCA is in place through the overnight. The next disturbance is on tap to arrive early Wednesday but won't pack much of a punch. But, the next system will arrive on Thursday. Winds will likely increase with this system but the exact details are still uncertain at this time.

4 to 6 feet seas are in the forecast through much of the week.

HYDROLOGY
No river flooding is expected through the next seven days.
